What is a search impression in Google Search Console?

Here an impression is not what someone takes away from meeting you, nor an ad impression in Google Ads, which has its own rules, nor a visit to your website. It is the metric Search Console uses to count the times your site showed up in Google's results, whether there was a click or not. For a store it is the first signal of all: a new product page gains impressions before clicks, and a drop in impressions warns you of a problem before you notice it in sales. But it is also the metric most often misread, because an impression does not guarantee that anyone saw the link.

How it works

Google's definition. An impression is counted when someone has seen, or could have seen, a link to your site in Search, in Discover or in Google News.⁠^{[1]Search Console Help. What are impressions, position, and clicks?} In the performance report, Google sums it up as the number of times your site appeared in the results.⁠^{[2]Search Console Help. Performance report (Search results)}

The general rule. On a normal results page, an item counts as an impression as soon as it appears on the results page being viewed, whether or not it reaches the screen, as long as nothing has to be clicked to see more results.⁠^{[1]Search Console Help. What are impressions, position, and clicks?} If your product page comes up in position eight and the searcher never scrolls past the third result, your page still adds an impression.

The exceptions. In carousels and in sections that expand, such as an FAQ result, the item normally has to come into view within the carousel, or be expanded with a click, to count.⁠^{[1]Search Console Help. What are impressions, position, and clicks?} And if someone only looks at the first results page, what is on the second registers no impression.⁠^{[1]Search Console Help. What are impressions, position, and clicks?} In infinite-scroll results, such as image search on mobile or a Discover card, the item also has to reach the screen. And going back and returning during the same search adds no new impressions.⁠^{[1]Search Console Help. What are impressions, position, and clicks?}

In Google's AI features. In AI Overviews the usual impression rules apply, clicking an external link counts as a click, and an AI Overview takes up a single position, so all its links get that same position.⁠^{[1]Search Console Help. What are impressions, position, and clicks?} The generative AI performance report separates those impressions from the rest.

By site or by page. The same result can add one impression or several depending on how you group the data. Grouped by site, an item with several links to your website counts a single impression; grouped by page, each linked page adds its own. Google's example is a knowledge panel with several text and image links to the same site: one impression if you look at the site, five pages with one impression each if you look at the pages.⁠^{[1]Search Console Help. What are impressions, position, and clicks?} That is why the total on the pages tab does not have to match the one on the queries tab.

From impression to CTR. The performance report gives four metrics: clicks, impressions, CTR (clicks divided by impressions) and average position.⁠^{[2]Search Console Help. Performance report (Search results)} Because CTR is calculated from impressions, anything that inflates or trims impressions also moves CTR. Google puts it its own way: the goal is not to have more impressions, but meaningful impressions, from people who find what you offer useful.⁠^{[1]Search Console Help. What are impressions, position, and clicks?}

The fine print on the data. Data usually takes two to three days to arrive; days are counted in Pacific time; very infrequent queries are removed from the table for privacy but count in the chart total; and the table shows a maximum of 1,000 rows.⁠^{[3]Search Console Help.

On a store

Three moments in the same product page over a month, each with its own tool. This is a fictional example: the store and the figures are invented to separate what each metric measures.

Three readings that work for any store. The first row measures opportunity, the second interest and the third business, and each one has its own fix: few impressions call for work on indexing or the product page's relevance; many impressions and few clicks, the title and the snippet; many clicks and few purchases, the product page itself. The first two come from Search Console with Google's definitions.⁠^{[1]Search Console Help. What are impressions, position, and clicks?} The third comes from Analytics, where a key event is an especially important action for the business, such as a purchase, that you mark as such.⁠^{[4]Google Analytics Help. About key events} They are two tools that do not count the same thing, so their figures do not line up row by row: a click is not a session, nor a session a purchase.

How to check it

1. Open the Search Console performance report and turn on the impressions, clicks and CTR metrics, to see the three together.⁠^{[2]Search Console Help. Performance report (Search results)}
2. Look at the same product page on the queries tab and on the pages tab. If the totals do not match, it is not an error: the way of grouping changes.⁠^{[1]Search Console Help. What are impressions, position, and clicks?}⁠^{[3]Search Console Help. Performance report (Search results): Troubleshooting data discrepancies}
3. Filter by search type. Text web search, multimodal search (the kind that starts from an image, like Google Lens), image, video and news search are counted separately.⁠^{[2]Search Console Help. Performance report (Search results)}
4. Leave out the latest days when comparing periods: data takes two to three days to arrive and is counted in Pacific time.⁠^{[3]Search Console Help. Performance report (Search results): Troubleshooting data discrepancies}
5. For the conversion, go to Google Analytics and check that the purchase is marked as a key event; if it is not, there is no third row to compare.⁠^{[4]Google Analytics Help. About key events}

Related concept: CTR

CTR (click-through rate) is the quotient of clicks and impressions.⁠^{[2]Search Console Help. Performance report (Search results)} The impression is the denominator: it says how many times you showed up; CTR says what share of those times convinced someone. That is why a falling CTR is not always bad news: if a product page starts appearing in many more searches, even in low positions where almost nobody clicks, impressions rise faster than clicks and CTR falls, with the same number of visits or more. Before judging CTR, look at what happened to impressions. And before judging either, remember that the sale is measured in another tool, and that part of it may arrive by another route, as assisted conversion explains.

To keep going, the measurement and verification reading path puts the rest of the terms in order.
