Q: What do clicks, impressions, CTR, and average position mean?

The four Performance report metrics in one place: what each measures, how they are calculated and grouped, and how to read them together without errors.

They are the four metrics at the top of Search Console's Performance report. Clicks count visits from Google to your site. Impressions count how often a link to your site was shown. CTR is clicks divided by impressions. Average position is where your link ranked, 1 being the top, averaged across searches. Each answers a different question, and none of them tells the whole story alone.

The four metrics at a glance

Metric	Measures	Calculated as	Watch out for
Clicks	People who left Google for your page	A count; a repeat click on the same link counts once	Interactions that stay on Google are not clicks
Impressions	Times a link to your site was on screen	A count, with rules for carousels, expandable blocks and page two	Grows when you rank, even badly, for more searches
CTR	How often an impression became a click	Clicks ÷ impressions	Heavily tied to position and to what else is on the page
Average position	Where your topmost link sat	The best position per search, averaged	Only recorded when there is an impression

The report shows clicks and impressions by default. Select the Average CTR and Average position boxes above the chart to add the other two to the chart and the table.

How grouping changes the numbers

Search Console counts in two ways, and it matters which one you are looking at:

By property (the chart, and the queries, countries, devices and dates tables): all your links in one result count as one impression, and position is the topmost of them.
By page (the pages and search appearance tables): each URL counts separately.

Google's example is a knowledge panel showing five of your pages. By property that is one impression; by page it is five, one for each URL. This is why the totals in the pages table can exceed the chart, and why CTR and average position look better when grouped by property.

Reading the four together

Single metrics mislead; combinations explain. A few patterns:

Impressions up, position down, clicks flat. You now appear for many new, broader searches, mostly low in the results. Growth, not decline.
Position steady, CTR down. The results page around you changed (an AI Overview, ads, a video block) or a competitor's snippet became more attractive.
Clicks down, impressions down, position steady. Fewer people are searching. Compare year on year to separate seasonality from a real loss.
Position better, clicks the same. You moved from 15 to 9: an improvement, but still below the positions where most clicks happen.

The deeper question behind each metric has its own page: clicks versus impressions, how CTR is calculated and how to interpret average position.

Three rules that prevent most mistakes

Read totals from the chart, not from summing table rows: rare queries are left out of the rows but counted in the totals.
Compare like with like. The same number of days, ideally whole weeks, and the same search type (web, image, video, news).
Segment before concluding. Split by device, country, or branded versus non-branded queries; an average over everything hides opposite movements.
