The Complete Guide to SEO, GEO and AEO Strategy for AI Search
A complete SEO, GEO and AEO strategy is one plan with three goals. SEO gets your pages ranked in Google. AEO (answer engine optimization) shapes them so a search engine can lift them as the direct answer to a question. GEO (generative engine optimization) makes them the sources that ChatGPT, Perplexity, Gemini and Google’s AI Overviews quote. The work overlaps more than the acronyms suggest. Google says there are no additional requirements or special optimizations needed to appear in AI Overviews or AI Mode: a page must be indexed and eligible to show with a snippet. So the order is simple. Fix the foundation, write pages that answer, back them with sources, then measure clicks and citations.
Plan for answers, and not only rankings, because of the click gap. SparkToro found that 68.01% of US Google searches ended without a click in January to April 2026, against 60.45% in 2024. When fewer searches send visitors, being the name inside the answer is part of being found.
SEO, GEO and AEO: what each one means
The three terms describe where you want to appear. Each asks something slightly different of your pages.
| Term | Where you show up | What it asks of your pages |
|---|---|---|
| SEO | Classic Google results | Crawlable, fast, indexed pages that match what people search |
| AEO | Direct answers to one question, in search results and AI summaries | A clear answer at the top of each section, question-style headings, lists and tables |
| GEO | AI answers that cite sources: ChatGPT, Perplexity, Gemini, AI Overviews, AI Mode | Facts with sources, numbers and quotes, plain language, insight only you can give |
For Google, the lines blur on purpose. Its AI features use the same index as classic search, and SparkToro’s 2026 study notes that AI answers draw heavily on what already ranks well. ChatGPT and Perplexity pick sources their own way. We test them directly instead of assuming Google’s rules carry over.
Layer 1: technical SEO that search and AI engines can read
If a page is not indexed, no engine can cite it. Google’s best practices for its AI features read like a technical SEO checklist. Each item is decided when the site is built.
- Allow crawling in robots.txt, and check that your CDN or hosting does not block crawlers either.
- Keep important content in text form, not only inside images or video.
- Link your pages to each other so engines can find every one of them.
- Meet the three Core Web Vitals: LCP, INP and CLS. INP replaced First Input Delay as a Core Web Vital in March 2024, so any checklist still listing FID is out of date.
- Design for phones first. SparkToro weights its 2026 panel at two-thirds mobile searches.
- Make sure structured data matches the text visible on the page.
- Keep your Google Business Profile and, for shops, Merchant Center details current.
Layer 2: AEO, or pages that answer the question
Answer engines lift short, self-contained passages. A page is easier to quote when each section opens with its answer and adds detail after.
- Open each section with a one or two sentence answer, then expand.
- Phrase headings the way people search, often as the question itself.
- Use lists for steps and tables for comparisons, prices and plans.
- Give each main question its own page or section, and link related pages together.
What changed with FAQ and HowTo schema
Many SEO guides still say FAQ and HowTo schema boost your snippet chances. That advice has expired. HowTo rich results were deprecated in September 2023. Google stopped showing the FAQ rich result on 7 May 2026 and removed its documentation on 15 June 2026. Google also says AI features need no special schema.org markup.
Schema is still worth adding where it describes what is really on the page and qualifies it for other rich results. Just stop treating it as a shortcut into AI answers.
Layer 3: GEO, or getting cited in AI answers
The best public evidence on GEO comes from a KDD ’24 paper by researchers at Princeton and IIT Delhi. They rewrote web pages in different ways and measured how often generative engines used them. Citing sources, adding quotations and adding statistics improved visibility by 30 to 40% on their main metric. Edits for fluency and easy reading added 15 to 30%. Keyword stuffing gave little to no improvement.
The most useful finding for smaller sites: pages ranked fifth in classic results gained 115.1% visibility from citing sources, while the top-ranked page lost 30.3% on average. A well-sourced page does not need the first position to be quoted. One caveat. The tests ran on BingChat, Google’s SGE (the experiment before today’s AI Overviews) and Perplexity, not ChatGPT. Read the numbers as direction, not a guarantee.
In practice, state facts with their source, quote named people, write short plain sentences, and add what only you know: your process, your prices, your cases. Tricks carry risk too. In May 2026 Google clarified that its spam policies also apply to its generative AI answers.
Do you need llms.txt?
Not for Google. Google says llms.txt files are not needed for Google Search and won’t help or hurt your rankings, though keeping one for other services is fine. We treat it as optional and cheap to maintain, never as a ranking fix.
How to measure SEO and GEO results
Search Console counts appearances in AI Overviews and AI Mode in the Performance report, under the “Web” search type. They are mixed in with classic results, so you read them through patterns rather than a separate line.
- Compare impressions and clicks per page. Rising impressions with flat clicks often means your page is seen in answers but not visited.
- Run the same set of prompts every month in ChatGPT, Perplexity, Gemini and Google AI Mode, and note whether your site is named or linked.
- Check pages you rank for against those prompt results. A ranking page that is never cited usually needs clearer answers or stronger sources.
Where to start: the order of work
- Confirm in Search Console and robots.txt that your key pages are indexed and crawlable.
- Fix Core Web Vitals and mobile layout on the pages that bring leads.
- Rewrite those pages so the first paragraph answers the main question.
- Add sources, numbers and your own cases to the pages you want quoted.
- Set a monthly prompt test and read it next to your Search Console data.
- Update pages when facts change. Advice that was true a year ago, like FAQ schema tips, now costs trust.
Why this belongs in the build, not a plugin
Most of the list above is decided when the website is built: how text renders, how pages link, how fast they load, which crawlers are allowed. Adding it later means reworking templates your team already uses. We see a website as a growth system your team runs every week, not a launch-and-forget project. So we build Webflow and Next.js sites with search and AI answers planned in from day one. We also set them up so the founder or one person in the office can edit pages without waiting for a developer. That matters for GEO, because answers stay quotable only while they stay current.
