Introducing A Better, Simpler Ad Rotation
The right ad rotation can help you show your best ads to people looking for what you have to offer. However, it’s not always clear which rotation makes the most sense for your business. That’s why, starting in late September, we’re simplifying ad rotation to two settings: “optimize” and “rotate indefinitely.”
Optimize for your best ads
Powered by Google’s machine learning technology, the new “optimize” setting prioritizes ads that are expected to perform better than other ads within an ad group. This setting will optimize your ads for clicks in each individual auction using signals like keyword, search term, device, location and more.
Keep in mind that using an optimized ad rotation with three or more ads per ad group can increase both clicks and impressions. The more of your ads our system can choose from, the better the expected ad performance.
If you’d like to prioritize conversions, the best way is to use Smart Bidding. Smart Bidding helps you tailor your bids based on the likelihood of a conversion, and will choose the ad most likely to drive that conversion. Note that if you’re using Smart Bidding, Ads will automatically use the “optimize” ad rotation.
Simplifying even rotation
While an optimized ad rotation works best for most advertisers, we know that some of you prefer more control with an even rotation. Because the “rotate indefinitely” setting is already the easiest way to give your ads equal preference, it will be the sole option for an even rotation going forward.
And to give you even more control, ad rotation settings will be available at the ad group level–meaning that you can use multiple rotation settings across a single campaign.
