Facebook announced earlier this month that they are going to retire the relevance score metric and replace it with three new ad relevance diagnostics metrics. The three new metrics will measure relevance more granularly across three separate dimensions.
Average Position has often been used as the source of truth in evaluating where ads are showing or the level of competition for any given campaign, ad group, ad or keyword. While this has been useful over the years, Google Ads is going to sunset this metric and replace with new metrics that were created to give a clearer view of how prominent your ad is on search results.
Like Responsive Search Ads in Google Search, there is now a display ad format that takes the AI learning and dynamic features of RSA into display efforts. This newer ad format is appropriately named Responsive Display Ads.
