To help you reach more potential customers, your ads will now show on content that matches any of the topics, placements or display/video/search keywords you target. For example, if you targeted 'bikes' as a topic and 'cycling' as a display/video keyword, your ads will show on content that matches either.
You’ll also notice contextual targeting simplified into a single page in Google Ads, so you can manage all content targeting types (topics, placements, display/video keywords and exclusions) in a single view. The new page can be found in the 'Content' section under Campaigns 
A targeting method you can use to specifically choose websites, videos, channels, apps and app categories that are part of YouTube and the Display Network where you'd like to show your ads. Unlike other targeting methods, where your ads are placed on sites automatically for you (like keyword targeting or topic targeting), you select the placements yourself.
- Placement targeting is an optional feature that can help you have more control over the websites, videos, channels, apps and app categories that can show your ads.
- You can add placements in the 'Content' section while creating a new campaign and you can edit existing placements through the Content page.
- By combining multiple content targeting methods, your ads will target any of the selected content in your ad group and help you reach a broader audience.
- You can use placement targeting to assign a unique bid to a specific web page. If your ad performs well when it shows on a certain web page, you could add it as a placement and set a higher bid. By adding the placement using the 'Change bid adjustment' setting, you can make your bid more competitive just for that particular placement.
