Three clients in three weeks have sent us versions of the same email. The subject line varies. The screenshot is always the same: a Search Console impressions chart that looks like a ski slope going the wrong way. The fear is identical too — are we being penalized? did the latest core update kill us?

In nine cases out of ten right now, the answer is no. Rankings are holding. Clicks are mostly steady. The impressions number itself has changed what it means.

What "impression" used to mean

It used to be straightforward. Your page appeared in a search result page that a user saw, you got an impression counted. If it was on page two, you still got it counted, just with a worse average position. The metric was a reasonable proxy for "how visible are we in Google."

That proxy has degraded badly over the last eighteen months, and the degradation accelerated this spring. Three things are happening at once, and most agency reports we've seen are still reporting impressions like none of them happened.

AI Overviews count differently than they used to

Through most of 2025, if your page was cited as a source inside an AI Overview, you got an impression credit each time the Overview appeared, more or less the way you'd have gotten one if you'd ranked in the equivalent organic slot. Around late February of this year, Google quietly changed the rules. AI Overview source citations now only count as impressions when the Overview is fully expanded and the user actually scrolls to the source list, or when the source is one of the inline-cited domains visible above the fold.

If your page is one of the six or eight sources at the bottom of a collapsed Overview, and the user reads the AI summary and bounces — you get nothing. No impression. No click. No data point. In the old counting, you'd have at least had the impression to compare against next month. Now you don't.

For sites with a lot of informational content — anything that gets picked up as an Overview source frequently — this single change can show up as a 15-25% drop in reported impressions, with zero change in actual ranking. We've measured it on three client properties so far. The rank tracker numbers are flat. The impressions are not.

Deduplication tightened

Google has always deduplicated results from the same site for a given query, but the rules got noticeably stricter in early 2026. If you have three pages that target overlapping queries — a category page, a guide, a product detail page that mentions the same topic — Google is now more likely to surface one of them and suppress the others. The suppressed ones used to still get logged as impressions in some configurations. They don't anymore.

The practical effect is that sites with deep, internally competing content libraries will see total impressions drop while click numbers stay flat. Google is showing the user the best page, the user is clicking it, and the four "almost as good" pages are no longer haunting the impression counter. It's mostly a reporting artifact. It looks alarming on the chart.

Bing is taking share

This one nobody wants to talk about because Bing has been a punchline since 2010, but the numbers are real. Bing's US desktop share went from around 6% in mid-2024 to something north of 11% as of last month, mostly driven by ChatGPT search routing through it and Edge's OS-level integration on Windows 11. Eleven percent isn't a lot. It is, however, three to four points more than Search Console is going to tell you about, because Search Console only reports Google.

If you're looking at total organic traffic in GA4 it'll show up as flat or up. If you're looking only at Search Console impressions, it'll look like decline. The traffic moved. The reporting tool didn't.

How to read the data correctly

We've changed how we look at Search Console for every client this year. Three rules.

One: always pair impressions with clicks and average position. If impressions are down but clicks are flat and position is stable, you are not losing ground. You are losing impressions that weren't generating clicks.

Two: segment by query type. The informational segment is where the AI Overview accounting change hits hardest. The transactional segment usually shows much smaller impression movement, which tells you the underlying ranking health is fine.

Three: stop reporting Search Console impressions as a top-line KPI. We're transitioning every retainer to a blended view — organic clicks from GA4 across engines, conversion rate from organic, and ranking position on a tracked keyword set. Impressions are a diagnostic, not a goal.

The one case it actually is bad

If impressions are down, clicks are down by a similar percentage, and your tracked keywords have moved against you on a rank tracker, then yes — you're losing visibility, and it's time to figure out why. That pattern shows up in maybe 10% of the impression-drop conversations we have. The other 90% are people scared by a chart that's measuring something different than it was a year ago.

The chart is not lying. It's just answering a different question now.
