Quick answer
AI search does not replace SEO. Pages still need to be crawlable, indexed and useful, and Google says AI features draw on the same foundations. What changes is that results appear inside written answers, so brands must also measure mentions and citations, not only rankings.
Key takeaways
- Crawlability, indexing and helpful content still come first.
- Answers reduce some clicks, so influence must be measured beyond traffic.
- Treat AI visibility as an added layer on your SEO, not a rival programme.
What still works?
Fast, indexable pages, clear titles, useful content, honest sourcing and a good site structure. Google states that to appear as a supporting link in AI features, a page needs to be indexed and eligible to be shown with a snippet, with no special extra markup required.
What is new?
- Users may read a summary and never click, so a mention can matter without a visit.
- Assistants compare and recommend, which puts third party sources in the spotlight.
- Answers vary between runs, so you need sampled measurement.
What should teams do?
Keep the SEO programme. Add a prompt set, report mention, recommendation and citation rates, and fix the omissions and source gaps that appear. Use the same content calendar for both.
What the data actually supports
There are two easy stories about AI and search. One says search is over. The other says nothing has changed. The evidence supports neither. It supports a narrower conclusion: some queries now end in an AI-written answer, clicks on ordinary results fall on those pages, and the fundamentals that decide whether a page can appear at all are unchanged.
8%
of visits included a click on a traditional result when an AI summary appeared
15%
of visits included one when no AI summary appeared
1%
of visits with an AI summary clicked a link inside the summary
These figures come from Pew Research Center's analysis of the browsing data of 900 U.S. adults during March 2025. They describe Google searches in one country and one month, and they measure clicks, not influence. A person who reads a brand name in an AI summary and searches for it later will not appear in these numbers at all.
Pew's data is one country and one month, and it measures clicks on Google. Read carefully, it says that on pages with an AI summary, ordinary results get clicked less often. It does not say those pages are unimportant to brands.
A forecast that shaped the debate
A forecast, not a measurement
Whatever the eventual measurement shows, the forecast made many teams ask the right question: what happens to our visibility if some of our audience starts with an assistant. The answer is to measure that layer directly.
Where SEO and AI visibility overlap
| Area | SEO | AI visibility | Shared foundation |
|---|---|---|---|
| Goal | Rank and earn clicks | Be named, described and cited in answers | Be the clearest, most credible answer |
| Measured by | Positions, clicks, traffic | Mention, recommendation and citation rates | A stable, defined method |
| Access | Crawlable, indexable pages | The same, plus readable by search-oriented AI crawlers | A healthy, fast, accessible site |
| Content | Useful pages for queries | Answer-first passages that can be quoted | Accurate, current, specific writing |
| Off-site | Links and authority | Independent descriptions and reviews | A credible presence beyond your own site |
How to split effort sensibly
- 1Keep the SEO programme running. Nothing here argues for cutting the base that AI features also rely on.
- 2Add a small, steady AI visibility layer: a prompt set, a monthly measurement and a short list of fixes.
- 3Reuse the same content work. A page rewritten as a clear direct answer helps both readers and systems.
- 4Review the two together each month so that findings in one inform the other.
What Google says about the base
A note on reporting
Report the two layers separately and then together. Clicks and rankings tell you about the search layer. Mention and citation rates from a fixed prompt set tell you about the answer layer. Showing both stops a fall in one from being mistaken for a fall in the other.
Should we cut SEO budget for GEO?
There is no evidence-based reason to. The two share foundations. Add measurement and clarity work instead of removing what already works.
Where do I start?
With the AEO checklist and a baseline prompt set.
Should I move budget from SEO to AI visibility?
The evidence does not support a wholesale move. The two share foundations, and the AI layer is best added as a measured extra. Adjust the split as your own data shows where your buyers are.
How do I explain this to a sceptical executive?
Show the Pew figures with their limits, show your own baseline mention rates on a fixed prompt set, and propose a small monthly measurement rather than a large reallocation.
