Google provides translated versions of our Help Center, though they are not meant to change the content of our policies. The English version is the official language we use to enforce our policies. To view this article in a different language, use the language dropdown at the bottom of the page.
Third-party ad serving is only available to a limited number of customers on a case-by-case basis. Except where indicated otherwise in this policy, all creatives related to a third-party tag must comply with Google's image ad policies.
You must comply with these policies if you serve ads or use pixel-tracking (beacons) on the Google Display Network and:
- Are participating in the third-party ad serving program.
- Use a third-party server.
- Use a research vendor.
- Are a third-party server.
- Are a research vendor.
If you have a Google Account Manager: Submit a request for third-party implementation for your Google Ads account with the Third-party tags and pixels implementation request form.
If you don't have a Google Account Manager:
- To request implementation of third-party 1x1 pixel and 3P viewability tags, submit the Third-party tags and pixels implementation request form.
- To request implementation of third-party ad tags, submit the Third-party ad tag implementation request for unmanaged accounts form.

Load:
- Initial load size:
- 150 kilobytes (KB) maximum is recommended for the fastest initial load time.
- For an optimum viewer experience, we recommend compressing and using the minimum required assets in initial load.
- Total non-viewer initiated load size*: 2.2 MB maximum.
- *Total non-viewer initiated load size includes initial and subsequent/polite loads.
- Viewer-initiated load size:
- Up to 10 MB per interaction.
- 2.2 MB maximum total load size is recommended for optimal performance.
- For an optimum viewer experience, third-party served ads must not exceed 40% of the central processing unit (CPU) capacity of a viewer’s computer. Common causes of high CPU use are continued animation, heavy animation sequences, and animation that surpasses the 30-second limit. If applicable, you can use the Task Manager feature in Windows to check for compliance with this rule.
Animation length:
- Maximum host-initiated play: 30 seconds
- Maximum user-initiated play (click required): 4 minutes
Creatives
- Creatives may not expand past ad unit boundaries.
- All creatives must be free of applications including, but not limited to, ActiveX, viruses, exit pops, spyware, and malware.
- Creative coding may not use cross-domain scripting or set cookies in unapproved domains.
- All creatives must open in new windows. The target window for the click-through URL must be set to "_blank" so the click-through will open in a new window. Do not leave the target statement undeclared.
- All sound and animation (including video) must stop upon exit click.
- On all ads with partially black, white, or transparent backgrounds, you must add a visible border of a contrasting color to the majority background color of the creative (i.e. not black if partially black, not white if partially white).
- You must supply a default image.
HTML5 creatives:
- File requirements
- Flash content and Flash fallback (SWFs and FLVs) are not allowed to serve with an HTML5 ad.
- HTML5 ads must include:
- <!DOCTYPE html> declaration and must contain a <html>, <head> and <body>tag.
- Ad dimensions must match the placement dimensions to prevent distortions. Add an ad size <meta> tag within the <head> tag.
- If your HTML5 ad includes video content, you must provide video assets in an MP4 format as well as either WebM or Ogg formats to ensure compatibility across all major browsers.
- Rich media and other features
-
Features including, but not limited to the following, must be fully tested and pre-approved for cross-device functionality by gTech. Any ad element not meeting the specifications in this policy will be returned for revision, which may cause a campaign delay.
- Expandable ad units
- In-banner video
- Research, including in-banner surveys or invitations
- Geolocation
- Forms
- Drag and drop or mouseover/hover interaction
- 3D transforms
-
Creatives
- Standard format image tags, iFrame and Javascript tags are eligible to run on the AdMob In-App Network.
- Keep in mind that the third party ad server will determine which creative to serve, so if a tag contains an unsupported file type (such as SWF), the ad server will serve the backup/default creative. Similarly, advertisers should be aware that if their third party served creatives contain other features, such as cookies, they may not be as effective in the mobile app environment.
- The only inventory available for mobile in-app expandables are interstitials, which are not available for third party ad serving at this time.
SSL-compliant ad units are accepted on the Google Display Network according to the following policies. We require that all ads and tracking pixels targeting SSL inventory are SSL-compliant. As SSL inventory increases on the web, non SSL-compliant ads will have fewer opportunities to serve and will win fewer auctions. To ensure your ads are eligible for the most amount of inventory, ads should follow the SSL-compliant ad guidelines below.
SSL-compliant ads guidelines
- Please notify your Google account representative that you are submitting an SSL-compliant ad. Note that if an ad is declared as SSL- compliant but makes any non-SSL-compliant responses, the ad will be disapproved.
- For secure pages (HTTPS://) the ad, creative and tracking pixels must only use HTTPS. Additionally, for ads and creatives loaded using a secure connection (HTTPS://), all subsequent requests to media assets or tracking URLs must also use a secure connection (HTTPS://). This means that all creatives must be able to deliver over HTTP and HTTPS without the need for special trafficking. If tracking pixel URLs are provided, they must be SSL compliant (begin with HTTPS://). The only part of an ad permitted to be non-SSL compliant is the click URL (target landing page).
- Any 4th-party calls to other technologies within the ad unit must also be from SSL-compliant vendors.
- Approved SSL-compliant ad vendors are listed in the Vendors lists.
You must comply with these policies if you use third-party tracking, including pixels (beacons) on the Google Display Network. The policies under “SSL-compliant ad units” also apply.
Format
Only 1x1 pixels are supported for third-party tracking site-served ad units. Javascript is not allowed.
Click trackers are supported for third-party tracking clicks on select site-served ad units. See the Ad formats section for a full list.
Certified vendors
Google Ads supports third-party tracking on the Google Display Network from certified vendors. Please consult the list of certified vendors for your region in the Vendor list section. Buyers may only use a technology vendor approved by Google, which must be declared per Google instructions.
Click tracking vendors are not required to be certified for third-party ad serving.
Fourth-party calls and multiple vendor tracking
Multiple impression pixels per event are not supported for our site-served display ad units through Google Ads. However, clients may submit up to 3 pixels per event (i.e., 3 impression, 3 view, and 3 skip) for site-served video ad units. For any additional pixels, clients may daisy-chain multiple vendor tracking or fourth-party calls into a single asset. This must be a standard format 1x1 pixel that fires simultaneous calls to each vendor upon serving the impression. The client or agency is responsible for piggybacking or daisy-chaining the pixels. The maximum amount of fourth-party calls permitted within a third party tag varies by the type of vendor that is being used (1 certified ad server or Rich Media vendor, 3 research products and 1 Online Behavioral Advertising Option Icon).
Ad formats
Third-party pixels are supported on the below ad formats. Some ad formats allow for multiple events to be tracked. However, only one pixel can be appended to site-served display units, while up to 3 pixels can be appended per event to site-served video ad units.
| Ad format | Pixels allowed | Click trackers allowed |
|---|---|---|
| Display (including Ready Lightbox) ads | Yes - 1 impression pixel | Yes |
| GDN Responsive ads | Yes - 1 impression pixel | Yes |
|
TrueView in-stream ads skippable |
Yes - up to 3 impression, 3 view, and 3 skip pixels | Yes |
|
TrueView in-stream ads non-skippable |
Yes - 3 impression pixel | Yes |
| Bumper ads | Yes - 3 impression pixel | Yes |
| Outstream ads | Yes - 3 impression pixel | Yes |
| In-feed video ads | No | No |
| Text ads | No | Yes |
| Gmail ads | No | Yes |
| Performance Max responsive ads | Yes - 1 impression pixel | No |
Companion banners
Separate tracking for companion banners is not supported for auction video ads. Videos and their accompanying companion banners will share the same tracking assets.
Policy Requirements on the Google Display Network through Google Ads
Google reserves the right to remove any ads deemed intrusive or inappropriate. Please review our advertising policies for more information.
Ads must:
- Conform to Google's specifications.
- Contain family safe content.
Ads may not:
- Contain fake hyperlinks.
- Resemble Windows, Unix, or Mac dialog boxes.
- Simulate fake interactivity.
- Contain sexual content.
- Contain audio (exception: user-initiated rich media ads).
- Initiate downloads.
- Be intrusive.
- Advertise competitive content.
- Contain misleading content.
- Cookies and targeting: You may use cookies for reporting purposes and creative selection, provided that the data you use was collected in accordance with industry standards:
- NAI Self-Regulatory Code of Conduct for Online Behavioral Advertising (networkadvertising.org)
- IAB UK Good Practice Principles for Online Behavioral Advertising (youronlinechoices.com)
Where there is a conflict between the NAI and IAB UK policies, the more stringent policy applies. Google determines at its own discretion whether or not you are compliant with these standards.
In particular, the certification process requires you to have the following:
- A descriptive privacy policy on your site
- A prominent link to opt-out from the privacy policy
- No PII used in the creation of segments (including PII related to the user's mobile phone device)
- No sensitive segments or segments targeted at children under 13 years of age
- No packet sniffing in the collection of behavioral data
You may not use locally shared object (LSO) technologies (including but not limited to flash cookies, browser helper objects, or HTML5 localStorage) or device fingerprints for behavioral advertising, ad delivery, reporting, and/or multi-site advertising.
- Data collection: You may use a cookie, web beacon, or other tracking mechanism to collect pseudonymous traffic data for purposes of aggregated reach, frequency and/or conversion reporting, provided you use a certified third party vendor for this purpose. Collecting impression-level data via cookies or other mechanisms for purposes of subsequent re-targeting, interest category categorization, or syndication to other parties on Google Display Network inventory is prohibited. (This restriction does not apply to view-level, click-level, or conversion-level data.) You may not associate cookies, web beacons, or other tracking mechanisms with personally- identifiable information (PII) for any purpose or with precise user location for behavior targeting unless the user has knowingly and expressly opted in. (For purposes of this document, PII and precise user location does not include IP addresses.) You will not, and will not assist or knowingly permit any third party, to set a cookie, or alter or delete a cookie set, on any Google owned and operated domains, including, without limitation, on a Search Ads 360 domain. You must display a prominent privacy policy with an option for users to persistently opt out of any cookie, web beacon, or other tracking mechanism set by you for data collection.
- Fourth-party calls: All ads may only include tracking elements from certified third-party servers or research vendors already approved by Google. No fourth-party calls are permitted, except tracking elements associated with certified third-party servers or research vendors expressly authorized by Google, calls to Google hosted and approved code libraries, jQueries to Google and Amazon storage, and jQueries solely for the purpose of creative rendering. We require the use of the AJAX post() method; the AJAX get() method is not allowed. For more information, see Guidance for complying with the Identifying Users Policy. All tags may only be associated with a single advertiser. Multiple advertisers cannot be represented through a single tag. The maximum amount of fourth-party calls permitted within a third party tag varies by the type of vendor(s) being used (1 certified ad server or Rich Media vendor, 3 research products and 1 Online Behavioral Advertising Option Icon).
- Creative approval: All creatives and tags that call the third-party server or research vendor must be fully tested and pre-approved by Google Ad Operations at least 72 hours prior to the campaign start date.
- Creative modifications: Creative substitution or modification via the third-party vendor without prior approval isn't allowed. All creatives must be pre-approved by Google Ad Operations. Any ads with dynamically changing content must be initially reviewed and pre-approved by Google Ad Operations but may be exempt from additional reviews and approvals at Google's sole discretion.
- Delays due to revisions: Any ad element not meeting the specifications in this policy will be returned for revision, which may cause a campaign delay.
- Tag performance: Tags must display consistently. If a tag doesn't conform to our performance or reliability standards, we reserve the right to pause or stop the campaign.
- Sending tags: All tags must be sent in an email text attachment, not in the body of an email.
- Reporting: Traffic or impression reports provided by Google will be the reports of record between Google and the advertising partner. Any reports delivered to the advertising partner by the third party will not affect the rights or obligations of Google and the advertising partner.
- Data from context-aware macros: Unless permitted otherwise by Google in writing, you may only use data from context- aware macros exclusively for the impression associated with that data. You may not use data from context-aware macros elsewhere or at any other time.
- Site-level tagging: If you use Google's placement targeting feature, you must aggregate a minimum of four unique web properties with adequate impression distribution across properties with each ad tag. You may not associate impression-level cookies, web beacons, or other tracking mechanisms with individual sites.
- Brand Features and Publicity: You may not publicly indicate your participation or compatibility with the program or disclose any relationship between you and Google without Google’s prior written approval.
- Google Analytics auto-tagging: Google Analytic's auto-tagging feature is not currently compatible with third-party served ads. If you rely on auto-tagging, we suggest using separate accounts for third-party served ads and Google Ads-hosted ads. Follow these instructions to enable or disable auto-tagging.
- Policies:
- When creating ads, you may not use cross-domain scripting or set cookies in unapproved domains.
- Ads must support Google's click-tracking. Where supported, all click events must be passed to Google.
- The http headers for Google's click-tracking URL must be sent by the viewer's browser. A client-side HTTP request, not a server-side request, must be sent to the Google click-tracking URL.
A pop-up:
- Is a window that opens in addition to the original window.
- Includes pop-unders, timed or intermittent pop-ups, mock system warnings, and pages that automatically initiate a download.
- Is prohibited regardless of its content.
Audio requirements:
- Effects must be user-initiated on click; ads may not play sound automatically.
- Audio settings must be set to 'off' by default.
- Users must have the option to mute all audio in the ad.
- Audio volume must be encoded at no more than -12 db.
Ads may not directly capture any personally-identifiable user information. Personal information includes, but isn't limited to, e-mail addresses, telephone numbers, and credit card numbers. No sensitive information can be collected through the ad.
You may not associate cookies, web beacons, or other tracking mechanisms with personally-identifiable information (PII) for any purpose or with precise user location for behavior targeting unless the user has knowingly and expressly opted in. (For purposes of this document, PII and precise user location does not include IP addresses.)
If authorized by Google, you may implement research studies in connection with an ad campaign. If expressly approved by Google, these research studies may be exempt from some of the third-party serving restrictions outlined above.
All research must be conducted as follows:
- You may conduct research only for the purpose of measuring the effectiveness of mutually agreed-upon, ad-served advertising placements purchased through Google.
- Google must approve, in writing, the public disclosure of any campaign-specific data and compilation or aggregation of data across multiple campaigns attributable to Google prior to any such disclosure.
- Only a third-party research provider that appears on Google's approved provider list may conduct research.
- A maximum of 3 research products (Analytics/Performance, Brand-Lift Studies, Verification Services, etc) are allowed within an ad tag. Even if a Google-paid study is conducted, this should be included in the 3-product maximum.
- All methodologies and survey tools (including recruitment processes, incentives, solicitation/invitation content, questionnaire content, data collection, and survey appearance) will be subject to Google's advance approval.
- For brand studies, please reference the following survey content guidelines.
- You are responsible for ensuring that all survey results and associated data are kept strictly confidential, and that personally- identifiable data is not solicited or collected, except as necessary by you for granting incentives to research participants. All personally-identifiable data may be used only to deliver the relevant incentives, and such data must be destroyed promptly following delivery of the relevant incentives.
- If you are a verification or audience metric service provider, as classified by Google, you must be able to demonstrate that your service has gone through a formal third-party audit. Any data you collect must be used strictly for reporting against the advertiser's campaign. You must not collect site-level information (domain/URL) in connection with a cookie. You may not sell or make available for resale any information you may collect via your service to others. You may not share or aggregate data beyond the advertiser's campaign for whom you are providing the reporting. Note: Verification Services are not permitted to drop cookies.
- Verification and audience metric service providers may only be used for research and analytics purposes. You may not use any technology that will effect or prevent the serving of the ad, which includes but is not limited to services like ad blocking. Certification of these vendors only indicates that Google permits their use by clients on our network, but Google does not validate the accuracy of the data and analysis reported by any research vendors in our program including but not limited to verification and audience metric service providers. Google does not offer credits for any discrepancies between our reports and the third party's reports or for any issues flagged by these types of services.
If you would like to display a third-party Advertising Option Icon for online behaviorally targeted ads, you must abide by the following requirements:
- For ads served on the Google Display Network for most publishers, Google's Advertising Option Icon (“AdChoices”) will appear at the top right corner of the ad unit in accordance to industry standards.
- If you choose to use a third-party Advertising Option Icon and layer it over the Google Advertising Option Icon, the third-party vendor is responsible for complying to the requirements outlined by the Self- Regulatory Program for Online Behavioral Advertising (aboutads.info), which includes but is not limited to the following specifications:
- The layer must use the Advertising Option Icon’s official 76x15 “AdChoices” image. If the 19x15 “i” image is used instead, the layer should change to the full 76x15 “AdChoices” image upon mouseover.
- The Icon must appear in the top-right corner of the ad.
- The ad must have a z-index value of less than 9010 to ensure that the Google and third-party icon appear above the ad. If you are using an expandable ad unit, the initial unexpanded layer of the creative must still have a z-index value that is less than 9010, and the expanded layer must have a z-index value greater than 1110.
- Additionally, if a third-party Advertising Option Icon covers the Google Advertising Option Icon, the 3rd-party icon must include the Google, Inc. as a company associated with user data collection and/or usage within the ad, and the user must be provided with Google’s cookie opt-out.
- Any privacy notification must appear within the ad units boundaries or open in a new browser window. No pop-ups are allowed.
- Any vendors that are permitted by Google to display an Advertising Option Icon may not write and/or read cookies in association with any functionality of the icon.
- You may only serve third-party Advertising Option Icons from a Google-approved vendor. See the list of approved Google Ads third-party vendors and search for vendors that include "Advertising option icon" in the "Product offerings" column.
Requirements on the Google Display Network through the Google Ad Manager
To run ads on the Google Display Network through the Google Ad Manager, you must follow the requirements below.
- Cookies and targeting: You may use cookies for reporting purposes and to target ads, provided that the data you use was collected in accordance with industry standards:
- NAI Self-Regulatory Code of Conduct for Online Behavioral Advertising (networkadvertising.org)
- IAB UK Good Practice Principles for Online Behavioral Advertising (youronlinechoices.com)
Where there is a conflict between the NAI and IAB UK policies, the more stringent policy applies. Google determines at its own discretion whether or not you are compliant with these standards.
In particular, the certification process requires you to have the following:
- A descriptive privacy policy on your site
- A prominent link to opt-out from the privacy policy
- No PII used in the creation of segments (including PII related to the user's mobile phone device)

- Data collection: You may use a cookie, web beacon, or other tracking mechanism to collect pseudonymous traffic data for purposes of aggregated reach, frequency and/or conversion reporting, provided you use a certified third party vendor for this purpose. Collecting impression-level data via cookies or other mechanisms for purposes of subsequent re-targeting, interest category categorization, or syndication to other parties on Google Display Network inventory is prohibited. (This restriction does not apply to click- or conversion-level data.) You may not associate cookies, web beacons, or other tracking mechanisms with personally- identifiable information (PII) for any purpose or with precise user location for behavior targeting unless the user has knowingly and expressly opted in. (For purposes of this document, PII and precise user location does not include IP addresses.) You will not, and will not assist or knowingly permit any third party, to set a cookie, or alter or delete a cookie set, on any Google owned and operated domains, including, without limitation, on a Search Ads 360 domain. You must display a prominent privacy policy with an option for users to persistently opt out of any cookie, web beacon, or other tracking mechanism set by you for data collection. Please note that 3rd-party reported reach and frequency numbers tend to be less accurate on the mobile platform.
- Fourth-party calls: All ads may only include tracking elements from certified third-party servers or research vendors already approved by Google. No fourth-party calls are permitted, except tracking elements associated with certified third-party servers or research vendors expressly authorized by Google.
- Tag performance: Tags must display consistently. If a tag doesn't conform to our performance or reliability standards, we reserve the right to pause or stop the campaign.

- Standard image banner ads must be served via a standard redirect tag, as in: <a href="..."><img src="..." /></a>
SSL-compliant ad units are accepted on the Google Display Network according to the following policies:
SSL-compliant ads guidelines
- All ad responses must be SSL-compliant (“HTTPS”). All servers involved require full SSL certification.
- It is preferred that your ad tag can auto-detect that it is being requested from the HTTP/HTTPS protocol and will auto-adjust any responses to be SSL-compliant if necessary. Otherwise, Google has a protocol macro that we can insert in any URIs or ad tags to auto-update “http” to “https” if necessary.
- Any 4th-party calls to other technologies within the ad unit must also be from SSL-compliant vendors that have been certified by Google.
- Ad Exchange buyers must declare through RTB or the Ad Exchange UI that the ad is SSL-compliant. Note that if an ad is declared as SSL-compliant but makes any non-SSL-compliant responses, the ad will be disapproved.
- Please see the section In-stream video ad units (VAST-compliant) for SSL-compliant VAST ad specifications.
- A vendor must receive specific certification to serve ads on SSL-compliant publisher inventory. Approved SSL-compliant ad vendors are listed in the Vendors lists.

Creatives
- Third-party, in-stream ads must be served via a linear VAST tag (pre-fetch tag) by a VAST vendor approved specifically for Ad Exchange.
- The VAST tag must comply with Google's XML summary for VAST ad server response.
- For each video ad served in the VAST tag, there needs to be a minimum of 2 separate nodes included - one for MP4 and WebM video formats. Other formats may be included, but will not be used.
- Consistent <AdSystem> Node Value: Please be sure that your all of your VAST tags include a specific consistent value for your company in the <AdSystem> node in the VAST XML. For example, Google would always include the following for all our VAST tags: <AdSystem>Google</AdSystem>
- Unique Ad ID Value: Each VAST tag generated should include a unique value for the “id” attribute in the node. Two different VAST tags should not have the same Ad id value. For instance:
- VAST tag 1: <Ad id="3947179">
- VAST tag 2: <Ad id="8741831"> - Note that only the following resource types will be allowed for
node in the VAST XML:- StaticResource: URI to a static file, such as an image or SWF file
- IFrameResource: URI source for an IFrame to display the companion element
The HTMLResource type will no longer be permitted.
- For Google’s Flash SDK to serve video ads from a 3rd-party ad server, the 3rd-party ad server must include a crossdomain.xml with specifications to allow access to all specific Google domains or all domains. Also, the attribute secure needs to be set to “false”. The crossdomain.xml should be formatted as follows:
<cross-domain-policy>
<!-- Allow access to ALL domains
<allow-access-from domain="*" secure="false"/>
<!-- OR allow access to the domain from originating request
</cross-domain-policy>Important: When you add a domain to your website's crossdomain.xml file, any Flash file hosted within that domain can access data belonging to users logged into your website. Due to this, you should generally not add advertising network hosts to crossdomain.xml files on websites that contain authenticated functionality such as user profiles.
- For Google’s HTML5 SDK to serve video ads from a third-party ad server, the third-party ad server must include a CORS header in all of its responses. The CORS header must be formatted as follows:
Access-Control-Allow-Origin: [allow access to the domain from originating request]
OR Access-Control-Allow-Origin: *
Note: Access-Control-Allow-Origin: * cannot be use in combination with Access-Control-Allow-Credentials: true - Audio is not allowed for companion ads.
- Creatives may not expand past ad unit boundaries.
- On all ads with partially black, white, or transparent backgrounds, you must add a visible border of a contrasting color to the majority background color of the creative.
- All creatives must be free of applications including, but not limited to, ActiveX, viruses, exit pops, spyware, and malware.
- Companion ads containing Flash must not exceed 50% of a user's CPU. Common causes of high CPU use are continued animation, heavy animation sequences, and animation that surpasses the 30-second limit. If applicable, you can use the Task Manager feature in Windows to check for compliance with this rule.
- Creative coding may not use cross-domain scripting or set cookies in unapproved domains.
- All creatives must open in new windows. The target window for the click-through URL must be set to "_blank" so the click-through will open in a new window. Do not leave the target statement undeclared.
- For Flash creatives:
- Creatives must be built to use Flash versions 7 through 11.2 (AS2 & AS3).

- It is preferred that your VAST tag can auto-detect that it is being requested from the HTTP/HTTPS protocol and will auto-adjust the URIs and companion banners to be SSL-compliant if necessary. Otherwise, Google has a protocol macro that we can insert in your VAST tag to auto-update “http” to “https” if necessary.

If authorized by Google, you may implement research studies in connection with an ad campaign. If expressly approved by Google, these research studies may be exempt from some of the third-party serving restrictions outlined above. Research tags may not be used in in-app ad campaigns.
All research must be conducted as follows:
- You may conduct research only for the purpose of measuring the effectiveness of mutually agreed-upon, ad-served advertising placements purchased through Google. You may only use a web beacon or other tracking mechanism in order to track a user's exposure to an ad. No surveys or survey invitations are allowed to be served on the Google Display Network via the Ad Exchange. When trafficking 3rd-party tags that serve surveys and survey invitations, the appropriate research vendor needs to be selected from the "Ad Technology" drop-down in the user interface. This will allow the survey and survey invitations to run on other AdX inventory, but not the Google Display Network.
- Google must approve, in writing, the public disclosure of any campaign-specific data and compilation or aggregation of data across multiple campaigns attributable to Google prior to any such disclosure.
- Only a third-party research provider that appears on Google's approved provider list may conduct research.
- You are responsible for ensuring that all survey results and associated data are kept strictly confidential, and that personally- identifiable data is not solicited or collected, except as necessary by you for granting incentives to research participants. All personally-identifiable data may be used only to deliver the relevant incentives, and such data must be destroyed promptly following delivery of the relevant incentives.
- If you are a verification or audience metric service provider, as classified by Google, you must be able to demonstrate that your service has gone through a formal third-party audit. Any data you collect must be used strictly for reporting against the advertiser's campaign. You must not collect site-level information (domain/URL) in connection with a cookie. You may not sell or make available for resale any information you may collect via your service to others. You may not share or aggregate data beyond the advertiser's campaign for whom you are providing the reporting. NOTE: Verification Services are not permitted to drop cookies.
- Verification and audience metric service providers may only be used for research and analytics purposes. You may not use any technology that will effect or prevent the serving of the ad, which includes but is not limited to services like ad blocking. Certification of these vendors only indicates that Google permits their use by clients on our network, but Google does not validate the accuracy of the data and analysis reported by any research vendors in our program including but not limited to verification and audience metric service providers. Google does not offer credits for any discrepancies between our reports and the third party's reports or for any issues flagged by these types of services.
