First, check that the drop actually shows up in Google. Then look at which pages are losing traffic and whether they were earning you anything.
Since July 22, 2026, when Google turned on AI Overviews in France, many stores have seen their organic sessions fall. Some of that traffic wasn't buying from you anyway.
The benchmark
Start by comparing two numbers that should tell the same story. In April, at a clothing brand we support, GA4 reported organic traffic down 22% over one month.
We had the reflex everyone has: look for whatever had broken in SEO. Yet Search Console showed 7% fewer clicks, a slightly higher click-through rate, and the brand name alone accounting for about a third of clicks. SEO explained only a small part of the month's drop.
The gap comes from how each tool counts: GA4 can't see visitors who decline its cookies and groups sessions by its own rules, while Search Console counts clicks at the moment they leave Google.
If the drop is confirmed in Search Console, isolate the queries that contain your brand name. Google added a dedicated filter to the Performance report in late 2025, available only to top-level properties that receive enough queries.
Next, read impressions, position and clicks on the same line. Falling impressions point to shrinking demand, because the season is changing or a competitor has taken your spot.
If impressions and position hold but clicks still melt away, the results page has changed: an answer now appears above your link. In the United States, Pew Research measured that people click a traditional result in 8% of visits when an AI summary appears, versus 15% without one.
The rule
Measure organic traffic in sales and sign-ups rather than sessions. According to Ahrefs, 99.2% of queries that trigger an AI Overview are informational. At the end of 2025, on those queries, the top result had a click-through rate 58% lower on average on desktop when a summary appeared above it.
So the clicks that disappear mostly come from queries like "how to care for a wool sweater," typed by people who wanted an answer and now get it without leaving Google.
In our view, a store can lose a good share of its organic sessions without losing sales. Focus your defense on the pages that sell, since the purchase still happens on your site.
The steps
- The check. Put GA4 and Search Console side by side for the same dates. If the gap is large, fix your measurement before touching the site.
- The top twenty pages. Compare the two periods in the Pages tab of Search Console, export, then sort by clicks lost.
- The sort. On one side, pages that sell (collections, product pages, the brand page). On the other, pages that inform (guides, articles).
- Pages that sell. Useful collection copy and complete product data, with links leading to them from your articles.
- Pages that inform. A clear answer in the first paragraph, with numbers and sources, because that's what a summary picks up and cites.
- Sign-up. Every visitor coming from Google should be able to leave their email, for a newsletter or a back-in-stock alert.
- The line for leadership, if your numbers back it up:
"Our non-branded clicks on the pages that sell are holding. What we're losing are guide readers who rarely bought."
The trap
The temptation is to make up for it by publishing more informational articles, which is exactly the content automated answers replace best.
What keeps its value is what an AI can't do for you: your data, your tools, your products, and an audience that belongs to you, your newsletter, which doesn't depend on any search engine.
Also be wary of year-over-year comparisons until summer 2027, since they set a results page from before July 2026 against one from after.
