If you have multiple ads in an ad group, what does Google do?

• A. It rotates evenly regardless of performance.
• B. Google will optimize your ads and show the best performing one the most often.
• C. Ads are served randomly, no optimization.
• D. Bids are changed automatically for all ads.

Answer: (B)

When there are several ads in an ad group, Google uses delivery optimization to decide which ad to show in each auction. The system evaluates performance signals and predicts which ad is most likely to meet your goal, then serves that ad more often. Over time, the higher‑performing ads appear more frequently, helping you achieve better results. This is different from rotating ads evenly or serving them randomly. Bids are guided by your bidding strategy and aren’t simply swapped for all ads because of which ad is shown; the focus here is on optimizing which ad gets the impression.
