How AI search is changing SEO in 2026

AI search changes the results page and the way people ask questions. It does not change what earns visibility: pages that can be crawled, are indexed, and are clear and genuinely useful. Google says there are no extra requirements to appear in AI Overviews or AI Mode, and no special optimisation is needed.

What shifts is how much a few habits matter. This post covers what Google says, what really changes, and what we would do this quarter.

What Google says about AI features

Google’s page on AI features and your website is short and worth reading in full. The key points:

• There are no additional requirements to appear in AI Overviews or AI Mode, and no other special optimisations are necessary.
• A page must be indexed and eligible to be shown in Google Search with a snippet.
• You do not need new machine-readable files, AI text files or special markup.
• Traffic from these features is counted in your overall search traffic in Search Console, under the Web search type.
• The advice is the same as before: create helpful, reliable, people-first content, and keep the technical basics in order.

What really changes

Some answers now appear before the click

A question with one short answer, such as “what is a canonical tag”, can be answered on the results page. A page that only repeats the obvious will see fewer visits for that query.

A page that goes further still gives a reason to click: a worked example, a decision framework, a price range with its conditions, or a checklist someone can use today.

Questions get longer and keep going

AI Mode invites follow-up questions. Google describes a technique it calls query fan-out: it breaks a question into subtopics and runs many searches at once, then pulls the results together (Google).

For a writer, this means one page should answer the main question and the obvious next ones. We cover how to plan that in what changes when search becomes a conversation.

More places can cite you

ChatGPT search, Perplexity, Gemini and Copilot also show answers with sources. Each chooses sources in its own way, and none publishes a formula. Nobody can honestly promise you a citation. What you can control is how easy your page is to understand and quote.

Measurement is blurrier

Search Console does not split AI features out of the Web report. So watch the trend in impressions and clicks, but judge success by what the traffic does: enquiries, calls and sales.

What stays the same

Area	Still true	What to do
Crawling and indexing	A page that is not indexed cannot be shown	Check the Pages report in Search Console. Fix pages that are blocked or marked noindex by mistake
Helpful content	Google asks for people-first, reliable content	Write for the reader’s decision. Show who wrote the page and what they know
Speed and usability	Pages that are slow or hard to use lose people	See does page speed affect rankings
Mentions and links	Other sites referring to you still helps	Earn mentions from relevant sites. Keep your Google Business Profile accurate

Six things to do this quarter

1. Check indexing first. Open Search Console, go to Pages, and confirm your important pages are indexed. A page outside the index cannot be a source for anything.
2. Put the answer first. Under each question-style heading, answer in 40 to 60 words, then explain. It helps readers and it makes the page easy to quote. Writing content that AI answers can cite shows how.
3. Add what a summary cannot. Use your own process, a worked example, a mistake you see often, or your own data. If you do not have the data, say so rather than filling the gap.
4. Cover the follow-ups. For each page, list the three questions a reader asks next and answer them on the page or link to the page that does.
5. Be consistent about who you are. Use the same business name, address and service names on your site, Google Business Profile and LinkedIn.
6. Report on enquiries. Set up form submissions, calls and WhatsApp clicks as events in GA4, so you judge SEO by leads and not only by clicks.

Questions we hear

Do I need an llms.txt file for Google’s AI features?

No. Google says you do not need to create new machine-readable files or AI text files to appear in these features. We treat llms.txt as optional and low priority.

Will AI search remove organic traffic?

Nobody knows. For some questions the answer now sits on the results page, so some visits will not happen. We would not plan around one forecast. Track your own clicks and enquiries and adjust.

Should we stop publishing blog posts?

No, but stop publishing posts that say what everyone else says. Publish fewer posts with more in them.
