Google Search Console (GSC) is an important online tool to make your website SEO friendly. Website managers who see the value in SEO are generally already registered with Google Search Console.
Among its services, GSC offers performance reports for standard Google searches, Google news, and, as of recently, also for Google Discover. However, performance reports for Discover will only be shown in the Google Search Console if your website has reached a minimum number of specific “Discover impressions” over the last 16 months. This basically means the number of users who had a specific Discover card shown to them. Only one impression is ever counted per session. As well as the impressions, the Google Discover performance report shows you the metrics “Clicks” and “CTR” (click through rate, click rate, or clicks per impression).
A click is counted as a user clicking on the relevant Discover card and visiting the website from which the corresponding content was displayed. If the user simply shares the card, this is not counted as a click. The metric CTR tells you how often on average users have to see a card until they click on it and open the content. For example, a click rate of two percent means that, out of 100 users who were shown a specific card, two of them actually clicked on it and visited the website.
In its performance report for Discover, Google itself gives more information about how these metrics are presented and evaluated in the Google Search Console. It is important to continuously track SEO measures for their success if your goal is to constantly be improving your content for Google Discover.
