An advertiser is running two ad campaigns with different headlines. Campaign 1 has a click-through rate of 20%, while it's 8% for campaign 2. How can the advertiser optimize their ad creatives to improve the performance of both campaigns?

The correct answer is "Run both the campaigns with the same headline as campaign 1." By running both campaigns with the same headline as campaign 1, the advertiser can leverage the higher click-through rate (CTR) of 20% to improve the performance of campaign 2. Since campaign 1 is performing better, it indicates that the headline is more effective in capturing the audience's attention and driving clicks. Applying the same successful headline to both campaigns increases the likelihood that both will experience better engagement and performance. The goal is to standardize the creative elements that are proven to work, ensuring that both campaigns benefit from the higher-performing headline, rather than continuing to use less effective variations or trying to equalize them by using a less effective headline.
