Good SEO gets you most of the way to GEO, but not all of it. AI engines still crawl, index and weigh authority, so the foundations carry over; what’s new is how answers decide which brands to name. Most companies don’t need a separate GEO program. They need a GEO workstream inside search, sized to how their buyers research.
Definitions: SEO, GEO and AEO
- SEO (search engine optimization) is the work of ranking your pages in search results so people click through. The unit is the keyword and the ranked link.
- GEO (generative engine optimization) is the work of getting your brand mentioned, recommended and cited inside AI-generated answers: ChatGPT, Perplexity, Gemini, Claude, Microsoft Copilot, and Google’s AI Overviews and AI Mode. The unit is the prompt and the answer.
- AEO (answer engine optimization) is the older term, from the featured-snippet and voice-assistant era. It focuses on being the direct answer to a question. Today it’s used almost interchangeably with GEO.
The distinction that matters: in SEO, winning means a click. In GEO, winning often means being named in an answer the buyer reads without clicking, then visiting your site directly days later.
How search engines and AI engines choose sources
A search engine ranks documents by relevance, links and many quality signals. The reader sees the list and does the comparing.
An AI engine assembles an answer, and it draws on two sources:
- What the model learned in training. If your brand appeared often and consistently across the web before the training cutoff, the model may mention you without searching. You influence future models by being widely and accurately described.
- What it retrieves live. When an assistant searches the web, it pulls a handful of pages and writes an answer from them, usually with citations. Google describes AI Mode as breaking one question into several sub-queries (“query fan-out”), so a single prompt can pull sources from many searches.
Retrieval is where SEO and GEO meet. Google’s AI Overviews and AI Mode draw on Google’s index, and Google’s guidance says there are no extra technical requirements beyond being indexed and eligible to show with a snippet. Copilot runs on Bing, Bing has also been a source for ChatGPT search, and ChatGPT and Perplexity run their own crawlers. If you only watch Google, you can miss the assistants your buyers actually use.
The biggest difference is the shortlist. An AI answer does the comparing itself and usually names only a few options. Ranking sixth on Google still earns clicks; being sixth-best in an AI engine’s view usually means not being mentioned.
What carries over from SEO
Most of what makes a site rank also makes it retrievable and citable. Fix these before spending on GEO-specific work:
- Crawl access. Important content is in the server-rendered HTML, not only loaded by JavaScript. Many AI crawlers don’t run JavaScript.
- Indexing in Google and Bing. The site is verified in Bing Webmaster Tools, not just Search Console.
- No accidental bot blocking. robots.txt and CDN rules allow the search crawlers you want, including OAI-SearchBot and PerplexityBot.
- Authority. Links and brand mentions from credible sites still tell engines which sources to trust.
- Content quality. Pages that answer the question better than the alternatives get retrieved and quoted more.
- Clear structure. Descriptive headings, internal links and structured data make each page’s topic obvious.
This is why I push back when a company wants to “start GEO” on a site that’s half-indexed. No GEO tactic makes an AI engine cite a page it can’t fetch.
What’s genuinely new in GEO
Entity clarity
AI engines describe your company the way the web describes it. If your homepage says “revenue intelligence platform,” your LinkedIn says “sales analytics,” and review sites file you under “CRM,” the model has no consistent picture and won’t confidently recommend you for any of those categories.
Pick one category and one-sentence description, then make it match everywhere: homepage, About page, Organization schema with sameAs links, LinkedIn, review profiles, directories and partner listings.
Third-party mentions
SEO values links. GEO values mentions, linked or not, on the pages AI engines retrieve for category questions: “best X” roundups, comparison articles, review platforms, community threads, and media or analyst coverage. When an assistant answers “what are the best tools for Y,” it often builds the list from those pages, not from your homepage.
Citation-worthy facts
Models quote specific, checkable statements more readily than marketing language. Pricing, integrations, limits, who the product is for, original data and clear definitions all give an answer something to cite. “Plans start at $49 per user per month and include SSO” is citable. “Flexible pricing for teams of every size” is not.
Answer-ready formats
Put the direct answer in the first sentence or two under each heading, then the detail. Use comparison tables, short definitions and question-style subheadings that match how buyers ask. Prompts are longer and more specific than keywords (“best project tool for a 20-person agency that bills hourly”), so pages covering specific use cases match more of them.
For the execution side of all four, see the GEO service overview.
How measurement differs
SEO measurement is mature. GEO measurement is younger and noisier.
| SEO | GEO | |
|---|---|---|
| Unit | Keyword | Prompt |
| Visibility | Rankings, impressions | Mention rate, citation rate, share of voice vs competitors |
| Official data | Search Console, Bing Webmaster Tools | Limited; Google folds AI Overview and AI Mode data into overall Search Console totals |
| Stability | Fairly stable day to day | Answers vary between runs, users and models |
| Traffic | Organic sessions | AI referral sessions (chatgpt.com, perplexity.ai, gemini.google.com and others), usually small |
| Business signal | Organic conversions, pipeline | Self-reported attribution, branded search and direct traffic trends |
Three practical rules:
- Track a fixed prompt set. Write 30-50 prompts your buyers actually ask, run them on a schedule across the engines that matter, and record whether you’re mentioned, cited and how you’re described.
- Separate AI referrals in GA4. Create a custom channel group so sessions from AI assistants don’t disappear into “Referral.” ChatGPT often adds
utm_source=chatgpt.comto outbound links. - Ask buyers. Add “ChatGPT or another AI assistant” to your “How did you hear about us?” field. Much of GEO’s value shows up as someone who read an answer and then came direct.
Don’t judge GEO by AI referral sessions alone; the answer often persuades without a click. The guide to tracking your brand in ChatGPT, Perplexity and AI Overviews covers the setup.
How to split effort and budget
Define the split as the share of search effort going to work that wouldn’t happen in an SEO-only plan: entity cleanup, mention programs, prompt tracking and restructuring pages for citation. The SEO share still feeds AI visibility.
These are my usual starting points, not benchmarks. Adjust them after the first baseline.
| Situation | SEO / GEO-specific | Why |
|---|---|---|
| New domain or technically weak site | 90 / 10 | AI engines can’t cite what they can’t crawl; fix foundations first |
| Local or service business | 85 / 15 | Google Business Profile, reviews and local pages do most of the work; reviews also feed AI answers |
| Ecommerce / DTC | 80 / 20 | Discovery still runs mostly through Google, Shopping and marketplaces; GEO work goes to reviews and roundups |
| B2B SaaS, considered purchase | 70 / 30 | Buyers build shortlists in AI chats; comparisons and third-party mentions decide inclusion |
| Established brand losing clicks to AI Overviews | 60 / 40 | Rankings are already strong; the gap is how answers present you |
A worked example with round numbers: a B2B SaaS company spends $10,000 a month on search. At 70/30, $3,000 goes to GEO-specific work: about $1,500 on third-party presence (review profiles, roundup outreach, partner content), $1,000 on making comparison, pricing and use-case pages citation-ready, and $500 on prompt tracking. The other $7,000 keeps the SEO engine running.
Mistakes I see when companies set this up:
- Hiring a separate GEO vendor that rewrites pages the SEO team just optimized. One owner, one roadmap.
- Buying a tracking tool before fixing crawl access. You pay to measure a problem you can often fix in a day.
- Treating AI referral traffic as the main KPI. It’s small by design; shortlist inclusion is the real goal.
- Faking consensus. Planted reviews and astroturfed forum posts break platform rules and tend to get removed or called out.
That’s how I run GEO and AI search visibility work: inside the search program, with its own line in the plan and its own metrics.
A combined six-month roadmap
One team, two tracks, shared pages, with a monthly checkpoint.
| Month | SEO track | GEO track | Checkpoint |
|---|---|---|---|
| 1 | Technical audit: crawl, index, rendering, Bing Webmaster Tools | Build the prompt set, baseline mentions vs 3-5 competitors, confirm AI search crawlers are allowed | Baseline report |
| 2 | Fix high-impact technical issues; map keywords to commercial pages | Entity cleanup: one category, one description, About page, Organization schema, consistent profiles | Same description everywhere |
| 3 | Rewrite top commercial pages for search intent | Make the same pages answer-ready: direct answers, specs, pricing, tables | 10-20 priority pages shipped |
| 4 | Publish comparison and alternatives pages | Third-party program: review profiles, roundup inclusion, partner pages, podcasts | Target mention sources worked |
| 5 | Content for gaps in keyword data | Content for gaps in prompt data; publish original data others can cite | Top gaps covered |
| 6 | Report rankings and organic pipeline | Re-run prompt set vs baseline; review self-reported attribution | Reset the split for the next six months |
Month 6 is the decision point. If prompt visibility and self-reported AI mentions are rising, hold or increase the GEO share. If nothing moved, check whether the gap is authority (too few mentions) or content (nothing citable) before shifting budget.
