What Are SEO and GEO? Being Visible in Search and AI
Over the past year, my clients' question has changed. First they asked "are we showing up on Google", now they ask "does ChatGPT recommend us". The two look like the same question, but they are not. The first is about appearing in search results, the second is about being cited as a source inside an AI answer.
In this article I explain the difference between SEO and GEO, what a site needs to perform well in search engines, and what it takes to be cited in AI answers. Let me say it upfront: one does not replace the other. GEO is a new layer built on top of SEO.
What SEO is, briefly
SEO means search engine optimization. The goal is to rank high in organic results on engines like Google and Bing and bring the right person to the site. Here the measure is the click. The user sees ten results, clicks a few, and the rest stay on the screen.
SEO is not a list of tricks. It is a way of telling the search engine "this page genuinely answers this question". When the title, content, page speed, technical health, and off-site trust signals all tell the same story, the result follows.
What GEO is
GEO means generative engine optimization. It aims to make you a brand that is cited and referenced in the answers given by generative AI tools like ChatGPT, Perplexity, Gemini, and Google AI Overviews.
Here there is no ranking in the classic sense. The model writes a single answer and puts three, five, sometimes eight sources inside it. The user does not see ten blue links and choose. Either your name appears in the answer or it does not.
So winning at GEO does not mean being on the first page. It means being one of the sources the model trusts.
The difference between SEO and GEO
| Topic | SEO | GEO |
|---|---|---|
| Goal | High ranking and clicks | Citation and attribution inside the answer |
| Competition | Ten blue links | Three to eight sites in the source list |
| Main signal | Content, speed, backlinks, intent | Clear answer, structured data, trustworthy source |
| Measurement | Search Console and GA4 | Brand mentions, referral traffic, manual query testing |
The two share the same common ground: being a trustworthy source. Both the model and the user are really asking one thing. Does this page genuinely know this subject?
What influences SEO
Technical foundation: speed and a clean page
A fast-loading page is not a bonus, it is the price of admission. Sites that lag in Core Web Vitals measurements fall behind in ranking even when their content is good. Mobile load, HTTPS, the correct canonical tag, an up-to-date sitemap, and working redirects are all part of this foundation.
When I say a clean page, I do not mean design alone. Piles of unnecessary scripts, ads that cannot be closed, content hidden behind JavaScript, and unreadable HTML are also part of cleanliness. Googlebot and the visitor should both see the same clear content when they open the page.
On ferhatbalaban.com I generate pages server-side. The HTML sits in cache for an hour, so both the visitor and the bot get the same lightweight output. That solves speed and crawlability in a single move.
Content and search intent
A page should cover a single topic. Whatever the title promises, the answer should arrive in the first paragraph. If the user searches for "what is SEO", they do not want to read an agency pitch halfway down the page.
Depth matters too. If ten sites answer the same question the same way, the difference comes from your experience. A sentence like "in this project I tried this and got this result" is far more valuable than a copied definition.
Internal linking, category structure, and fresh dates also fall under this heading. Publishing a post and not touching it for three years is a silent way of telling the search engine this place is abandoned.
Authority and consistency
Links from outside the site still matter. But it is not just the count, it is who they come from and how relevant they are. Searches for your brand name, writing the same name and title the same way everywhere, and linking your social profiles to your site all grow trust.
What GEO requires
GEO should not be treated as a magic technique. The model cites a well-written and trustworthy page. The difference is that the page is organized in a way that makes the model's job easier.
1. A clear and short answer
Let the title ask the question, and let the first two or three sentences give the answer. The model produces a summary and skips long introductions. If the answer to "what is GEO" sits on the third screen of the page, it will most likely not be cited.
2. Structured data
Article, Person, Organization, and FAQPage schemas tell the machine what the page is. Adding your LinkedIn and Instagram profiles to the sameAs field of the Person schema is the cleanest way to confirm you are the same person. I have added this to the head across the site.
3. Quotable blocks
A definition paragraph, a bullet list, a comparison table, and a one-sentence conclusion. When the model builds an answer, it uses these blocks. Instead of long and scattered paragraphs, you need sections that carry meaning on their own.
4. Source and evidence
A date, a number, and a first-hand example. A sentence like "in October 2026 I made this change and saw this result" is far stronger than an unsourced claim. The model also cites these concrete statements more easily.
5. Crawlability
ChatGPT's GPTBot, Perplexity's bot, and Google's AI bots should not be blocked in robots.txt. Content should not sit behind a login wall. The llms.txt file is not a standard yet, but some clients read it, and adding it does no harm.
6. Consistent identity
The same name, the same title, the same service description everywhere. If the site says one thing and LinkedIn says another, the model struggles to merge the two into the same person.
7. Off-site mentions
LinkedIn, GitHub, industry directories, forums, and real client work. When the model sees the brand name consistently in different places, trust grows. Talking only on your own site is not enough.
No GEO without SEO
AI answers often draw from pages that are indexed and rank well. You cannot rescue a site with a broken technical foundation through GEO. On the other hand, good SEO alone is not enough either. You can be in the top three on Google and never be mentioned in an AI answer.
That is why I think of the two not as separate jobs but as two layers of the same job. SEO is the foundation of visibility, and GEO is the new surface of that visibility.
A 30-minute checklist
SEO
- Is there a single H1 on the page
- Is the title under 60 characters and the meta description under 155
- Is the heading and text easy to read on mobile
- Do the images have alt text
- Is the canonical address correct
- Is the sitemap up to date, and does robots.txt block the page
- Are there broken links or 404s
- Does the page load in under three seconds on mobile
GEO
- Does the first paragraph answer the question
- Is there Article, Person, and FAQ schema
- Are the social profiles filled in the sameAs field
- Is there at least one table or bullet list
- Are the publish and update dates visible
- Does robots.txt block GPTBot and PerplexityBot
- Is the same information also on your LinkedIn profile
- Have you asked ChatGPT about your brand and checked the answer
Finally
Search engine optimization has stood on the same foundation for twenty years: good content, a fast site, a clear structure, and trust. GEO does not tear this down, it adds a way of answering on top of it.
If you want to make a site visible both on Google and in AI answers, let us start with a clean page and a fast infrastructure. We will build the rest together.
