What is GEO and how it differs from classic SEO

Classic SEO answers the question "how to get into Google's top 10". GEO (Generative Engine Optimization) answers a different one: "how to make AI systems (ChatGPT, Perplexity, Gemini, Google AI Overviews) cite my brand in their answers".

Classic SEO
  • Fighting for a position in the list
  • Metrics: rankings, clicks, CTR
  • Users browse 3–5 sites to compare
  • Content written for humans
GEO (new reality)
  • Fighting for a mention in the AI answer
  • Metrics: citation frequency, share of voice
  • Users read one answer and decide
  • Content for AI + for humans
SEO and GEO are not competitors — they complement each other. But while SEO tracks rankings and clicks, GEO tracks how often your brand is cited in AI-generated answers.

Why 2026 is a turning point for AI search

If before, a customer in the search funnel would visit 3–5 sites and compare, now they read one generated answer and make a decision. Whoever is mentioned in that answer wins. Whoever isn't — simply doesn't exist.

The window of opportunity Most markets are 6–12 months behind the US in adapting to GEO. Claiming your position now is far cheaper than doing it a year from now. That window will close.

How AI decides who to cite

When a user asks a question, the model accesses a knowledge base in real time (retrieval-augmented generation, RAG) and extracts the most relevant fragments. Sources that get cited share specific traits:

  • Clear structure — H2/H3 headings that match exactly what users ask
  • Factual density — numbers, dates, specific examples instead of vague statements
  • Schema markup — structured data that explains to AI what's on the page
  • Brand reputation — mentions on independent external sources
  • Content freshness — visible publication and update dates
A site with structured facts, clear headings, tables and specific numbers gets cited tens of times more often than a site with beautiful but vague marketing copy.

7 GEO optimisation steps you can start tomorrow

1. Check whether AI can see you at all

Go to ChatGPT, Perplexity and Google AI Overviews. Ask 8–10 questions your business should answer. Build a table: query / system / mentioned or not / which competitors / tone. This is your baseline benchmark for the next 6 months.

⚠️
If you're not mentioned — you have not one problem, but three AI doesn't know you, your competitors are already there, and clients are going to them. Without this benchmark you won't know if GEO is working at all.

2. Add schema markup to all key pages

Schema explains to AI what's on the page. Without it — just a wall of text. With it — a structured database that's easy to extract facts from.

  • Organization — who you are as a company
  • LocalBusiness — if you have a physical location
  • Service — on service pages
  • Article — on all blog posts
  • FAQPage — on Q&A blocks
  • Review / AggregateRating — for client reviews

3. Rewrite your content in "AI-friendly" format

Imagine your text is being read by a machine searching for short factual answers. Clear H2/H3 headings matching specific questions, numbers instead of general statements, direct answer in the first sentence of each paragraph.

💡
The "out-of-context" test Write so that a single sentence makes sense on its own. AI often extracts one sentence and inserts it into an answer. If your sentence starts with "This means that..." without explaining what "this" is — no one will use it.

4. Create expert content with real data

AI hates "generic fluff". What it loves:

  • Your case studies with specific numbers ("client X, niche Y, was 12 leads/month, became 47 in 90 days")
  • Internal market research and original analytics
  • Statistics you collected from your own projects
  • Expert opinions attributed to real named authors
One case study with real numbers gets cited more often than twenty "top-10 tips" articles.

5. Build brand presence beyond your website

AI evaluates not just your website, but everything written about you across the internet. The more mentions from independent sources — the higher the chance AI recognises you as an authority.

  • Optimised Google Business profile
  • Registration in industry directories (clutch.co, designrush, G2)
  • Regular guest posts on relevant publications
  • LinkedIn activity from real team members
  • Client reviews on third-party platforms

6. Optimise for E-E-A-T

Experience, Expertise, Authoritativeness, Trustworthiness — in 2026 this is critical for AI. Anonymous articles are almost never cited — AI can't verify the source.

👤
What to do right now Every key page needs a real author with a bio and LinkedIn link. Your "About" page should be a full document with team photos, roles and specific experience. AI evaluates this mechanically through structured data.

Common mistakes that kill your AI visibility

❌
Mistake 1 — "perfect" marketing site with no real substance Test: replace your company name with a competitor's. If the text is still just as true — it's empty. AI never cites vague phrases like "we are the best, we are reliable".
❌
Mistake 2 — a blog full of 300-word posts AI cites in-depth content from 1,500 words with specific data. One 3,000-word article per week beats five shallow ones in the same time.
❌
Mistake 3 — AI bots blocked in robots.txt Check yourdomain.com/robots.txt — are GPTBot, ClaudeBot, PerplexityBot allowed to crawl your site? Many teams block all new bots "just in case" — making the site completely invisible to AI.
❌
Mistake 4 — outdated content AI prioritises freshness. A 2022 article has almost no chance against a 2026 one on the same topic. Every 6 months — update your top 10 blog posts with fresh data.

Frequently asked questions about GEO

Will GEO replace SEO?

No — they complement each other. Core principles overlap: quality content, technical accessibility, expertise. But the tools and metrics are different. Ideally, run both in parallel.

How much does GEO optimisation cost?

Basic technical fixes (schema, robots.txt, content structure) — from $300. A full strategy with content plan and mention building — from $800/month.

Can I do GEO without an agency?

The basics — yes: schema, rewriting key pages, adding FAQ blocks. Deeper work with external mentions and visibility monitoring usually requires either an in-house team or an agency.

What tools to use for GEO monitoring?

Semrush AIO, Profound, Otterly — or manual checks in ChatGPT, Perplexity and Gemini once a week, logged in Google Sheets.

Do I need to redo the whole site for GEO?

No. Optimise 10–15 key pages: homepage, main service pages, most important blog posts. Visibility starts there, then you scale.
