If your search clicks are falling, how do you know whether your SEO and link building are still working? This guide separates the numbers that have become unreliable from the ones that still show progress, and gives you a monthly report you can copy.
Clicks are the last step in a long chain. When an AI summary answers the question on the results page, fewer people take that last step, even if your page was shown and helped. So measure the steps before the click (links, impressions, brand searches) and the steps after it (enquiries, sales), and treat the click count as one number among several.
Start with the best independent evidence we could find, and be clear about what it covers.
Pew Research Center, July 2025. Pew tracked the browsing of 900 U.S. adults who belong to an online panel and agreed to install a tracking app. It looked at 68,879 unique Google searches from March 2025. About 18% of those searches (12,593) produced an AI summary. Pew found that people who saw an AI summary clicked a traditional result link in 8% of visits. People who didn't see one clicked a result in 15% of visits. Clicks on a link inside the AI summary itself happened in 1% of visits. And the browsing session ended after the page on 26% of pages with an AI summary, against 16% of pages with only traditional results. Pew counts a session as ended when the person exits the browser for five seconds or more.
Clicks and exits, with and without an AI summary
What this doesn't show: it covers Google only, U.S. adults only, and one month in 2025. It says nothing about any single website, and it can't tell you whether the person who didn't click got what they needed.
Ahrefs, February 2026. Ahrefs compared 150,000 keywords that triggered an AI Overview in December 2025 with 150,000 informational keywords that didn't, using aggregated Search Console data (average desktop click-through rate, which is clicks divided by impressions). For the page ranking first, the rate on keywords with an AI Overview fell from 0.073 in December 2023 to 0.016 in December 2025. On keywords without one it fell from 0.076 to 0.039. Ahrefs' headline figure is 58% lower, up from 34.5% in its April 2025 version of the study. Limits: desktop only, only keywords that had an AI Overview in December 2025, and Ahrefs sells SEO software.
Google, August 2025. Liz Reid, who leads Google Search, wrote that total organic click volume from Google Search to websites "has been relatively stable year-over-year" and that average click quality has increased. The post gives no figures, charts or method for that statement.
So the sources disagree. Pew and Ahrefs measure click behavior on results pages that show AI summaries. Google makes a claim about total clicks across all of Search, without showing its work. Both can be partly true: individual results can lose clicks while the total holds up. Nobody outside Google can check the total.
Our view: you don't need to settle that argument. You need a measurement setup that works if clicks keep falling and still works if they don't.
A click needs three things in a row: your page is shown, the person chooses it, and they leave the results page for yours. AI summaries mostly interfere with the second and third steps. Your page can be shown just as often as before and still get fewer visits.
Other things also move clicks, with no AI involved: seasonality, a rival's new page, a change in how Google lays out the page, and your own edits. Pew's finding that people exit more often after an AI summary is a reminder that "no click" can mean "question answered", not "page ignored".
That's why a single number, such as organic sessions, can't tell you whether your SEO and link building work. It tells you how many people arrived. It doesn't tell you how many people saw you, remembered you, or came back later by typing your name.
Many people assume AI traffic is hidden. It's more accurate to say it's blended in. Here is what Google's own pages say.
Two practical points follow. First, you can't pull "AI clicks" out of the main Performance report; they sit with everything else in Web. Second, the AI report counts shown links, not visits, so a rise there is a sign of being included, not a sign of traffic.
None of these proves that a link caused a result. Together they tell a story that a click count alone can't.
Count the sites that newly link to you each month, and note whether they're relevant to your topic and market. This is the most direct measure of the work you paid for or did. Our guide to link quality metrics explains how to judge a site without leaning on one score, and how to measure link building success covers checking each placement.
Where a link was paid for, keep in mind that Google's spam policies treat links that are bought or sold to pass ranking signals as link spam, unless the link is marked rel="sponsored" or rel="nofollow". Some placements carry a label. Record which ones do, so your count is honest.
A link that sends no one is still a link, but one that sends real readers is a link people actually saw. In your analytics, look at sessions from referral sources and see which linking pages bring readers who do something useful. Small numbers are normal. Judge direction over several months.
When more people search your name, your products or your domain, someone has heard of you. Search Console has a branded queries filter in the Performance report. Google's help defines branded queries as those that include your brand name, domain, or a brand-specific product or service, including common misspellings and variations. The filter isn't available for sub-properties (such as a site's /blog/ section) or for sites with few impressions, and its data starts from March 11, 2025. Compare branded impressions and clicks across quarters, not weeks.
This number is the closest cheap proxy for "more people know us", and it holds up when AI summaries answer the general questions.
Put impressions and clicks for the same pages next to each other and watch the gap. Rising impressions with flat or falling clicks is the pattern you'd expect when summaries take some of the clicks. Falling impressions is a different problem: you're being shown less. Don't judge by average position alone, for the reason above.
Count the enquiries that matter to the business, and ask new customers how they found you. A required "How did you hear about us?" field on a contact form costs nothing. In Google Analytics 4, the attribution reports let you compare attribution models side by side, which helps you see organic search or referral visits that came earlier in a path and didn't get the last click.
What to watch, and what to stop leaning on
Still shows progress
Don't rely on alone
These numbers are invented to show the reasoning. They aren't from a real client.
A small software company reviews April against January:
A click-only view says "traffic fell 10%, SEO isn't working." The wider view says the site was shown 20% more often, a smaller share of people clicked, more people searched the brand name, the link profile grew with relevant sites, and enquiries rose 10%. That isn't proof that links caused the rise in enquiries. It is enough to say the program isn't failing, and enough to keep going and look again next quarter.
The reverse case matters too. If impressions, branded searches and enquiries all fall while clicks fall, there is a real problem to investigate.
Keep it to one page. The same fields every month matter more than clever charts.
Month and comparison: [This month] against [last month] and against [the same month last year].
Search Console, Web search type: impressions, clicks and click-through rate for [your 5 to 10 key pages]. Note the change in each.
Branded searches: impressions and clicks with the branded queries filter on, if your site has access to it.
Generative AI report: impressions shown, if the report appears for your site. Treat it as "was shown", not "was visited".
Links: new referring domains this month, with the site name, the country and why it fits. Mark any placement that carries a sponsored label or a nofollow attribute.
Referral visits: sessions from the pages that link to you, and what those visitors did.
Business results: enquiries, calls, demo requests or sales, and where new customers say they heard of you.
Changes we made: new pages, edits, redirects, campaigns, anything that could move the numbers.
Notes and next step: one sentence on what the data does and doesn't support, and one action for next month.
