What is GEO and how is it different from SEO?
SEO (Search Engine Optimization) optimises your content to appear in a list of results that the user then browses and compares. GEO (Generative Engine Optimization) optimises your content so an AI reads it, understands it and cites it directly inside a written answer — often without the user ever visiting your site or seeing any other result.
GEO doesn't replace SEO: it builds on top of it. Most of the signals that already work for ranking on Google remain relevant, but there are additional signals that only matter when what's "reading" your content is a language model rather than a user scrolling.
The two mechanisms AIs use to answer
It's key not to confuse them, since they're optimised differently:
- Live search — ChatGPT with browsing, Perplexity, Copilot: they run a real search query on the spot and write the answer from those results, citing sources. This depends directly on your SEO ranking and your presence in the directories and listings that engine consults.
- Trained knowledge — what the model "knows" from memory, without searching, learned during training. This depends on how often and in what context your brand was mentioned in press, directories, forums or reference pages. It changes very slowly and isn't actionable short-term.
Practical implication: today, most of the available lever is the same as classic SEO, plus having a presence in the specific directories and listings these AIs consult when they search live.
Traditional SEO vs GEO: comparison table
| Dimension | Traditional SEO | GEO |
|---|---|---|
| Goal | Appear in the results list | Be cited inside an answer |
| Winning format | Optimised titles and snippets | Self-contained question→answer content |
| Key signals | Backlinks, keywords, speed | Schema markup, brand consistency, directories |
| Speed of change | Slow, measured in months | Fast, shifts with every model update |
| Measurement | Search Console, rankings | Still no standard; audited via mentions |
Technical checklist: 6 actions to become "citable"
- Schema.org markup (Organization, LocalBusiness, FAQPage) — helps the model extract structured data instead of having to interpret free-form HTML.
- Content in question→answer format, short and self-contained — the format these engines prefer to quote verbatim.
llms.txtfile at your domain root — an emerging standard that summarises what your company is and links your most relevant content.- Presence in sector directories and listings — exactly the pages Perplexity and ChatGPT cite when someone asks "best providers of X in [city]".
- Brand consistency (NAP): same name, address and phone number across your site, social media and directories.
- Backlinks and press mentions — still the strongest authority signal, both for SEO and for the model's long-term trained knowledge.
Our own case: on dataversesolutions.net we implemented exactly this checklist: Schema.org markup (Organization, WebSite, FAQPage) across all 4 language versions, an llms.txt file, fixed old URLs that returned errors and sent bad-quality signals, and sign-ups in sector directories. You can verify it yourself: ask ChatGPT or Perplexity "AI consulting firms in Barcelona" and check which sources it cites.
The most common mistakes that block your AI visibility
- Orphaned or 404 pages still indexed — they erode the crawler's trust in the rest of the site.
- Content with no clear structure: everything in one long block of text, with no direct questions and answers a model can extract.
- Zero presence in the directories and listings where your potential customers already search for providers.
- Brand inconsistency between your site, social media and directories (different name, address or phone number).
- Relying only on the homepage, with no dedicated pages or posts per service or topic that can be cited independently.
How to get started: 3 questions to self-assess your business
- If you ask ChatGPT "who offers [your service] in [your city]", does your company show up? If not, that's your starting point.
- Does your site have Schema.org markup and an
llms.txtfile? If not, it's the fastest technical improvement to apply. - Do you appear in the directories and listings where your potential customers already search for providers? If not, that's your next priority.
Conclusion
GEO doesn't replace SEO: it extends it. The companies that gain visibility over the next few years will be the ones that treat conversational AIs as another acquisition channel, with their own technical checklist and their own content strategy.
