A

Average position

Average position is the mean rank of a page or query across all its impressions. It is an average of very different situations and moves for reasons that are not always improvements.

C

Conversion rate

Conversion rate is the share of visits that complete a defined goal — a purchase, a lead, a booking. In SEO it is what turns traffic into a business case.

CTR (click-through rate)

CTR is clicks divided by impressions. In organic search it depends on position, on what else occupies the result page, and on how compelling the title and snippet are.

G

Google Search Console

Search Console is Google's free reporting tool for site owners: real impressions, clicks, positions, index coverage, Core Web Vitals and structured data status.

I

Impressions

An impression is counted when a page appears in search results for a query, whether or not anyone scrolled to it. It measures eligibility, not visibility.
