What are the main metrics to monitor when optimizing retail media campaigns? Select all that apply.

The selected answer options are correct because both Spend-through and ROAS are key metrics to monitor when optimizing retail media campaigns. Spend-through refers to the total amount of money spent on the campaign relative to the budget, helping advertisers track whether they are staying within their allocated budget and how effectively their ad spend is being utilized. Monitoring spend-through ensures that the campaign's financial performance aligns with the set goals. ROAS (Return on Ad Spend) is another critical metric, as it measures the revenue generated for each dollar spent on the campaign, indicating how effectively the campaign is driving sales and providing a return on investment. By focusing on these two metrics, advertisers can assess both the efficiency of their spend and the overall effectiveness of their campaigns in generating profitable results. Although CTR (Click-Through Rate) is also important, the focus on Spend-through and ROAS provides a deeper understanding of campaign performance in terms of both cost and revenue generation. Campaign name, on the other hand, is not a performance metric and does not directly influence optimization decisions.
