The short answer: SEO gets your website found and ranked on Google, while GEO (Generative Engine Optimization) gets your content picked and cited when ChatGPT, Perplexity, Gemini or Google AI Overviews put together an answer. One does not replace the other. GEO sits on top of SEO: a page that search engines have not indexed and do not trust is very unlikely to be quoted by an AI engine.
This article explains the difference, where many brands go wrong, and what you can start doing on your company website right away.
What are SEO and GEO?
SEO (Search Engine Optimization) is the work of getting your pages to appear in search results for the keywords your prospects search for. It is measured the classic way: rankings, clicks and leads from organic search.
GEO (Generative Engine Optimization) is the work of making your content the source AI engines draw on when they answer a question. The measure changes: not "what position are we in" but "is our brand mentioned and linked in the AI answer".
| SEO | GEO | |
|---|---|---|
| Goal | Rankings and clicks in search results | Being mentioned and cited in AI answers |
| Where it shows | Google's list of results | Google AI Overviews, ChatGPT, Perplexity, Gemini |
| What is judged | Relevance, quality, backlinks, technical health | Clear answers, verifiable facts, source credibility |
| Success metric | Rankings, organic traffic, leads | Mention frequency, AI referral traffic, brand mentions |
Why GEO still needs SEO
Many people assume GEO is a "new SEO" you can do without the basics. It is the other way round. In its documentation on AI features, Google says SEO best practices remain relevant for AI Overviews and AI Mode, and that there are no additional requirements or special optimizations needed to appear there. Other AI engines also generally find candidate pages through a search index before writing an answer.
So the order of work is clear:
- Pages must be crawlable and indexed.
- Pages must be judged relevant and high quality for their topic.
- Only then does the way you write decide whether your passage is the one that gets quoted.
Do not put basic SEO on hold to chase GEO. Do both at once.
What makes content get cited by AI
An academic study titled GEO: Generative Engine Optimization (Aggarwal et al., presented at KDD 2024) tested different ways of writing and their effect on visibility in AI answers. The key finding: adding source citations, quotations and statistics raised a page's visibility in AI answers by up to about 40%. Old tricks such as keyword stuffing did not help.
From our work on brand websites and content, the most consistent patterns are:
- Answer first. AI engines look for sentences that answer the question directly. If the answer only appears in the fourth paragraph, your chances drop.
- Verifiable facts. Numbers, dates, named standards and clear sources are easier to trust and to quote.
- Your own data. Campaign results, customer surveys and case studies are things competitors do not have, so they can only be cited from you.
- A clear author and date. Articles without an author or date are hard to judge for credibility and freshness.
- Clean structure. Question-style subheadings, bullet lists and comparison tables make it easy for AI to lift the right passage.
7 practical steps for a company website
1. Make sure content can be read without JavaScript
Many modern websites show their content through JavaScript in the browser. Some AI crawlers do not run JavaScript, so all they see is an empty page. Make sure important pages are rendered on the server or prerendered into static HTML.
2. Answer one question per article
Pick one real question prospects ask often, and answer it in the first two sentences. The rest explains, gives examples and lays out steps. The best list of questions usually comes from your sales team and the people answering your WhatsApp.
3. Build a topic cluster, not random articles
Write several related articles around one theme and connect them with internal links to your service pages. This helps search engines understand that your website is an authority on that topic.
4. Add data and sources
Every claim with a number should have a source you can link to. Better still is data of your own, such as the average cost per lead across campaigns you have run, shared with client permission or in anonymised form.
5. Add structured data
Use Article or BlogPosting schema, FAQPage for question-and-answer sections, and Organization for your company identity. Schema helps machines understand who wrote a page, when it was published and what it covers.
6. Update old articles regularly
Outdated content easily loses out to newer pages on the same topic. Review articles every three to six months: refresh figures, examples and the "updated" date.
7. Build your reputation beyond your website
AI engines also judge a brand by what other sources say: Google reviews, business directories, press coverage and social media conversations. Consistent business name, address and description across every channel matters too.
Mistakes to avoid
Mass-producing unedited AI articles. Google's spam policies call publishing many pages mainly to manipulate rankings, with no value added for readers, scaled content abuse. The policy applies whether the content is written by people or by AI. What is judged is the purpose and the usefulness.
Writing only "what is..." articles. Definition questions are increasingly answered by AI directly, without the user clicking through. Articles that keep their value cover how-to, comparisons, case studies and business decisions.
Blocking AI crawlers without thinking it through. Blocking every AI bot in robots.txt does keep your content out of model training, but it can also close the door on your brand being mentioned in AI answers. Make a deliberate choice rather than copying someone else's settings.
Frequently asked questions
Is SEO still relevant now that AI Overviews exist?
Yes. Google says SEO best practices still apply to AI Overviews and AI Mode, so pages that are strong in SEO remain the main candidates to be cited.
How long do SEO and GEO take to show results?
For a website that is just starting, it usually takes three to six months of consistent content before organic traffic and AI citations begin to show. Older, trusted domains can move faster.
How many articles should we publish?
Quality matters more than quantity. Two to three good articles a week on a focused topic usually beat dozens of thin ones.
Can we write articles with the help of AI?
Yes, as long as a person edits the result, checks the facts and the article genuinely adds value for readers. Google judges how useful content is, not which tool made it.
Conclusion
SEO makes sure your website is found. GEO makes sure your brand is mentioned when people ask AI. Both demand the same thing: content that answers real questions, is grounded in facts, is clearly structured and is written by people who know the field.
