Best GEO Techniques for Generative Search Engines (2026)
Some GEO techniques have been tested in controlled experiments. Most of the advice in circulation hasn’t.
We stick to the first kind here, using peer-reviewed research, platform documentation and our own tracking data. You’ll also find technical GEO and a way to test any technique on your own prompts. If you need the definition first, read what generative engine optimization is.
Key takeaways
- In the GEO paper, citing sources, adding quotations and adding statistics raised source visibility by 30% to 40%.
- Keyword stuffing was the only tested method that scored below the unchanged text.
- Lower-ranked pages gained most: a source ranked fifth saw a 115.1% visibility increase from citing sources.
- AI search engines strongly favor earned media over brand-owned content, so third-party mentions are a core technique.
- Technical GEO means allowing AI search crawlers, keeping key text in the HTML and matching schema to visible content.
What does the research say about GEO techniques?
The paper "GEO: Generative Engine Optimization" by Aggarwal et al. was accepted at KDD 2024. It tested nine ways to rewrite a source page and measured that source’s visibility in generated answers.
The authors built GEO-bench, a set of 10,000 queries across 25 domains. They measured how much of each answer drew on the rewritten source.
Results varied by topic. Statistics did best on law and government, debate and opinion queries, while quotations did best on people and society, explanation and history.
The paper also tested Perplexity.ai. There, Quotation Addition improved the main visibility metric by 22%, while keyword stuffing did 10% worse than baseline.
Why lower-ranked pages gain the most
So these techniques pay off most for pages on page one that aren’t at the top. Better evidence can win them a share of the answer.
The best GEO techniques for generative search engines
The first four techniques come straight from the GEO study. The rest come from platform documentation and from what we see in tracked answers.
1. Cite credible sources
Link each claim to a primary source, such as official documentation or a named study. Put the link right next to the claim it supports.
Citing sources was one of the three strongest methods in the GEO paper. It gives human readers a reason to trust the page, too.
2. Add statistics with context
Replace vague phrases such as "many teams" with a number, a date and a source. Keep the sample and time frame in the same or the next sentence.
Original data works best, because nobody else can supply it. A small, well-described sample beats a recycled industry number.
3. Add short quotations from named experts
A one-sentence quote from a named person with a clear role gives the engine a statement it can attribute. Pick quotes that say something specific. General praise adds nothing.
In the Perplexity test, Quotation Addition led on the main visibility metric. It did best on questions about people and society.
4. Write fluent, easy-to-understand answers
Fluency and readability rewrites gained 15% to 30% in the study. Use short sentences and plain words, with one idea per paragraph.
Open each section with a sentence that answers its heading. Then add detail and examples.
5. Match the format to the prompt intent
Engines reuse the format that fits the question. Pick the page type before you write.
- A "best" or "top" prompt calls for a ranked guide with stated criteria and the limits of each pick.
- A "how to" prompt wants numbered steps with an example and a short checklist.
- For a "what is" prompt, give a one- or two-sentence definition, then examples and related terms.
- An "X vs Y" prompt needs a comparison that applies the same criteria to each option.
6. Cover the follow-up questions with query fan-out
Google says AI Overviews and AI Mode may issue several related searches across subtopics before answering. This is called query fan-out.
List the sub-questions behind each priority prompt, such as pricing or integrations. Query fan-out analysis shows them. Then check that some page on your site answers each one that matters.
7. Earn mentions on third-party sources
The 2025 study "Generative Engine Optimization: How to Dominate AI Search" found a strong bias toward earned media. AI search engines favored third-party sources over brand-owned and social content.
Our data at Ansvisor, an open-source AI search intelligence platform, points the same way (Ansvisor tracking data, September 15 to October 14, 2026).
Among third-party domains cited in our tracked answers, Reddit had the largest share at 14.5%. YouTube followed at 11.6%, GitHub at 11.5% and LinkedIn at 10.4%.
| Third-party domain | Share of third-party citations |
|---|---|
| 14.5% | |
| YouTube | 11.6% |
| GitHub | 11.5% |
| 10.4% |
So take part where those citations come from, whether that’s a subreddit, a YouTube channel or a GitHub repo. Skip fake mentions, which Google says are not as helpful as they might seem.
8. Keep your brand entity clear and consistent
Use one company name, one category description and the same product facts on your site, docs, review profiles and social pages. Engines need that consistency to name you in the right context.
Connect authors to bios that show real experience. When a price or a statistic changes, update it.
What is included in technical GEO?
Technical GEO is about whether AI search systems can reach and read your pages. Most of it is technical SEO. A few checks are specific to AI.
- Allow the search crawlers behind each engine, such as Googlebot, Bingbot, OAI-SearchBot and Claude-SearchBot.
- Keep priority pages indexable and eligible for a snippet in Google and Bing.
- Put key facts in HTML text. Facts that live only in images or PDFs, or behind tabs and scripts, may be missed.
- Use one canonical URL per page, and list only indexable pages in your sitemaps.
- Use schema that matches what users can see on the page.
- Return fast, consistent 200 responses to bots and users.
Which AI crawlers should you allow?
Search crawlers and training crawlers are different, so decide on each one.
OpenAI’s crawler documentation says sites that opt out of OAI-SearchBot will not be shown in ChatGPT search answers.
GPTBot is a separate OpenAI crawler for model training. You can block it and still allow OAI-SearchBot.
Anthropic runs ClaudeBot, Claude-User and Claude-SearchBot. Its crawler help page says blocking Claude-SearchBot may reduce your visibility and accuracy in search results.
Google-Extended controls whether your content is used for Gemini training and grounding. Google says it doesn’t affect inclusion in Google Search.
How to do technical GEO in seven steps
- Check robots.txt plus CDN and firewall rules for blocked search crawlers.
- Confirm priority pages return 200 and are indexed in Google Search Console and Bing Webmaster Tools.
- Watch Search Console’s generative AI performance reports for page impressions in AI Overviews and AI Mode.
- View the rendered HTML and confirm the key answers appear as text.
- Fix canonicals, redirects and sitemap entries for the same pages.
- Validate structured data and remove markup that doesn’t match visible content.
- Re-check after site releases. A template change can block crawlers by accident.

Do you need llms.txt or special schema?
Not for Google. Google’s guide to generative AI features says you need no AI text files, special markup or Markdown to appear. It adds that llms.txt neither helps nor harms visibility in Google Search.
If you publish an llms.txt file, treat it as an optional map. It never replaces crawlable pages, sitemaps and internal links.
Platform-specific GEO techniques
Each engine searches a different index, so check the basics for each one.
| Platform | GEO technique |
|---|---|
| ChatGPT | Allow OAI-SearchBot and earn mentions on the third-party sites ChatGPT cites for your prompts. |
| Google AI Overviews and AI Mode | Earn strong Google rankings, because both rely on core Search ranking systems. |
| Gemini | Keep Google indexing and brand facts consistent, and track Gemini apart from Search. |
| Microsoft Copilot | Verify your site in Bing Webmaster Tools and fix Bing indexing gaps. |
| Claude | Allow Claude-SearchBot and publish precise, well-sourced pages. |
| Perplexity | Keep pages fresh and accessible, since it searches the live web. |
Worked example: applying GEO techniques to one paragraph
Here’s a typical paragraph before and after four techniques.
"Every AI platform shows lots of sources, so getting cited is easy if your content is good."
"In Ansvisor tracking data from September 15 to October 14, 2026, Google AI Overviews cited about 14 links per answer. ChatGPT cited about 5, so a page has fewer citation slots to win there."
- The vague "lots of sources" became two specific numbers.
- The data source is named and dated in the same sentence.
- The fact comes first and the implication second.
- Two short sentences replace a vague claim that was also wrong.
How to improve your GEO rankings
GEO rankings are rates: how often you’re mentioned and cited across a prompt set. Test techniques against them the way you’d test ads.
- Pick 20 to 50 prompts where you are cited rarely or not at all.
- Record a two-week baseline of mentions and cited URLs on each platform.
- Change one thing on the target pages, such as adding sourced statistics.
- Keep a similar set of prompts and pages unchanged as a control.
- Re-run both sets weekly for four to eight weeks and compare citation rates.
