The "Ad rotation" setting allows you to specify how often you’d like the ads in your ad group to be served relative to one another. If you have multiple ads within an ad group, your ads will rotate because no more than one ad from your account can show at a time. In this article, you'll learn about ad rotation settings.
Ad rotation settings
You can use the "Ad rotation" setting in Shopping, Search and Display campaigns. There are 2 settings for ad rotation: "Optimize" and "Do not optimize".
Optimize
The "Optimize" setting optimizes your ads for clicks in each individual auction using signals (such as keywords, search terms, devices, locations, and more), and prioritizes ads that are expected to perform better than other ads within an ad group.
As data is accumulated, ad serving will become weighted more heavily in favor of the ads that appear statistically likely to perform better. Ads expected to attract more clicks (and conversions if you’re using a Smart Bidding strategy) are delivered more often into the ad auction than other ads in the ad group. These ads show more often, resulting in higher ad-served percentages. However, it's possible for ad serving to remain relatively even within this setting. For example, if ads in an ad group have similar performance, or if the ad group doesn’t receive a significant amount of impressions and clicks for some period of time, ad serving might remain the same.
Tip:
Do not optimize
The "Do not optimize" option means your ads will enter into the ad auction more evenly for an indefinite amount of time.
Keep in mind
"Do not optimize" isn’t recommended for most advertisers. While the percentage of impressions for ads served in the ad group will be more even than the other ad rotation options, the percentage of impressions for each ad may not be even due to the quality of the ad. An ad with high quality may appear on the first page of search results, while an ad with low quality may show on the second page of search results, which reaches a smaller number of users.
