What is GEO (generative engine optimization)?

GEO is the practice of making content more likely to be used and cited in AI-generated answers from tools such as Google AI Mode, ChatGPT and Perplexity. Google's position is that optimising for generative AI search is still SEO: original, expert, well-structured and crawlable content.

Is SEO dead because of AI search?

No. AI search engines still rely on crawling and ranking web pages to choose their sources. Studies show AI answers reduce clicks overall, but pages cited in AI answers receive more clicks than uncited ones, so strong SEO matters more than ever.

Do I need llms.txt or special schema for AI search?

Not for Google. Google's documentation says it does not use llms.txt and that no special schema is required for its AI features. Standard structured data is still useful for describing your business accurately.

How do I get my business mentioned by ChatGPT?

Make sure your site is crawlable, publish clear and expert answers to the questions your customers ask, keep your business information consistent across the web, and earn genuine mentions from publications and directories your industry trusts.

Do AI Overviews reduce website traffic?

On average, yes. Pew Research found people click traditional results about half as often when an AI summary appears. However, Seer Interactive found brands cited inside AI Overviews get substantially more clicks than brands that are not cited.

How to Rank in AI Search in 2026: Google AI Mode, ChatGPT and the Truth About GEO

Search has changed more in the last two years than in the previous ten. Google answers many questions directly with AI, ChatGPT and Perplexity act as research assistants, and a new acronym — GEO, generative engine optimisation — promises to get you into those answers. Some of the advice circulating is useful. Much of it is not. Here is what the evidence and Google's own documentation actually say.

How big is AI search now?

At I/O 2026, Google said AI Mode passed one billion monthly users and that AI Overviews and AI Mode are merging into a single AI search experience (Google).
Since October 13, Google's newest model, Gemini 4 Argon, powers AI Mode for Pro and Ultra subscribers (Google).
ChatGPT reported more than 900 million weekly users in early 2026.

What it does to clicks

The data is consistent: AI answers reduce clicks, but being cited helps.

Pew Research Center found users clicked a traditional result on 8% of visits when an AI summary appeared, versus 15% when none did — and clicked a link inside the summary on just 1% of visits (Pew).
Seer Interactive's 2026 study of 53 brands found organic click-through rates were lower on queries showing an AI Overview — but brands cited inside the AI Overview earned about 120% more organic clicks than uncited brands on informational queries (Seer Interactive).

So the goal has two parts: still rank well, and be the source the AI chooses to cite.

What Google officially says about "GEO"

Google published guidance on optimising for its generative AI features, last updated in July 2026 (Google Search Central). The key points:

"Optimizing for generative AI search is … still SEO." AEO and GEO are new labels for the same work.
No special markup or files are required. Google says it does not use llms.txt, and you do not need special schema or to "chunk" content for AI.
Do not mass-produce pages for AI. Creating pages purely to target the many sub-questions AI search generates can fall under Google's scaled-content abuse policy.
No third-party tool has access to Google's internal ranking or AI systems — be sceptical of anyone who claims to guarantee AI placement.
What helps: original, "non-commodity" content based on first-hand experience and expertise; clear headings and structure; a crawlable site; good images and video; accurate Business Profile and Merchant Center data.

That is good news for businesses with real expertise: AI search rewards the same things good SEO always did — just more strictly.

Where GEO research does help

The term "generative engine optimisation" comes from a 2023 academic paper by researchers at Princeton and others, which found that adding citations, quotations and statistics to content increased its visibility in AI-generated answers (GEO paper on arXiv). This lines up with Google's advice: content that is specific, sourced and genuinely informative is easier for AI systems to trust and quote.

A practical checklist for 2026

Content

Answer real questions directly. Put a clear, one- or two-sentence answer near the top, then go deeper.
Show first-hand experience. Case studies, original data, screenshots, pricing ranges you actually charge, lessons from real projects — the things generic AI content cannot copy.
Cite your sources and include numbers. Link to primary sources; attribute statistics with dates.
Keep content current. Update key pages when facts change and show the updated date.
Cover topics in depth rather than publishing many thin pages on near-identical keywords.

Structure

Use descriptive headings that match how people phrase questions.
Use lists and tables for steps and comparisons — they are easy for both readers and AI to extract.
Add FAQ sections where they genuinely help readers.
Use structured data (Organisation, Article, Product, LocalBusiness) to describe your business accurately — not as a ranking trick, but so your details are unambiguous.

Technical

Make sure your site is crawlable and fast, with important content in HTML rather than hidden behind scripts or logins.
Check your robots.txt — if you block AI crawlers, those assistants cannot read or cite you. Decide deliberately.
Keep your Google Business Profile complete: address, phone, categories, hours, photos and reviews.
Watch the Search Console generative AI report to see how you appear in AI features.

Authority

Earn genuine mentions in industry publications, directories and communities your customers trust. Google notes that seeking inauthentic mentions does not work.
Be consistent everywhere — the same company name, address, phone and description across your site and profiles.

What about ChatGPT and Perplexity?

ChatGPT and Perplexity search the live web through their own indexes and partners, then cite sources. The fundamentals are the same: be crawlable, be the clearest and most credible answer, and be mentioned by sites they already trust. ChatGPT drives the large majority of AI chatbot referral traffic today, but AI referrals are still a small share of total website traffic — so treat AI visibility as an addition to SEO, not a replacement.

Mistakes to avoid

Chasing "GEO hacks" — hidden prompts, keyword-stuffed FAQ blocks or invisible text for AI. They violate spam policies and erode trust.
Publishing AI-generated filler at scale. It is exactly the "commodity" content Google says it does not want.
Ignoring brand searches. As more answers happen inside AI, people who already know your name are your most valuable traffic. Build a brand worth searching for.

The bottom line

There is no secret formula for AI search. The businesses that show up in AI answers are the ones with clear, current, expert content, solid technical foundations and a real reputation. That is more work than a trick — but it compounds.
