What is considered a good benchmark ROAS for the Microsoft Retail Media onsite campaigns?

The selected answer option is correct because a 300% Return on Ad Spend (ROAS) is generally considered a good benchmark for onsite campaigns in the Microsoft Retail Media platform. A ROAS of 300% means that for every dollar spent on the campaign, the advertiser is generating three dollars in revenue, which is considered a strong return in the advertising industry. This benchmark reflects a balanced and effective campaign that is driving significant sales while maintaining efficient ad spend. While higher ROAS figures (such as 1,000%+) are possible in some highly optimized campaigns, 300% is typically a reasonable and achievable goal for most advertisers, indicating that the campaign is performing well and delivering substantial returns on investment.
