An advertiser is running two ad campaigns with different deals. Campaign 1 has a Best Deals offer with a return on ad spend of $8.42, while it's $4.82 for campaign 2 that has a Subscribe & Save offer. How can the advertiser optimize their ad creatives to improve performance of both the campaigns?

The correct answer is "Run both the campaigns with a Best Deals offer." Since Campaign 1, which uses a Best Deals offer, has a higher return on ad spend (ROAS) of $8.42 compared to Campaign 2's ROAS of $4.82 with a Subscribe & Save offer, the advertiser can optimize performance by running both campaigns with the Best Deals offer. The Best Deals offer is clearly generating a higher return, indicating that it resonates better with customers or has more appeal, leading to higher sales relative to ad spend. By standardizing the offer across both campaigns, the advertiser can improve consistency in performance and potentially increase sales, as the Best Deals offer is proving more effective at driving conversions. In contrast, continuing with the Subscribe & Save offer or using different offers in both campaigns might lead to inefficiencies and missed opportunities for optimization.
