What this tile shows
High impressions with a low CTR usually means your title and description, not your ranking.

Where the number comes from
Google Search Console. Organic search performance: clicks, impressions, position, and query data.
What you need for it to appear
A connected Google Search Console property, through the same single Google sign-in.
