Let AI crawlers in. Otherwise you are invisible.
AI assistants can only cite what they can read. Many sites block AI crawlers in robots.txt without knowing it, often through old rules that block all bots.
Do this: open your robots.txt and make sure the settings are right: which bots are allowed (and not allowed) to visit which pages.
What about llms.txt? It does no harm, but Google's official guidance (May 2026) says it is not used for Search, AI Overviews or AI Mode. Focus on robots.txt instead.

Answer the question first. Explain after.
LLMs favor content that gives a clear, complete answer early on the page. Long introductions make content harder to cite, and industry data suggests AI citations are drawn disproportionately from the first part of a page.
Do this: open every important page with two or three sentences that answer its main question directly, then go deeper.

Statistics, expert quotes and sources: the strongest evidence.
The first major academic study in the field tested nine tactics across 10,000 queries. Three stood out: adding statistics, expert quotes and source citations increased visibility in AI answers by 30 to 40 percent.
Do this: review your most important pages and add concrete numbers, quotes from named experts and linked sources where it makes sense.

Structure your visible content for machine reading.
A clear heading hierarchy, bullet lists, tables and FAQ sections make content easy to extract. Important: several AI crawlers do not render JavaScript, so content that only appears after JS rendering may never be read. Microsoft's official guidance points the same way: do not hide key content in tabs, PDFs or images only.
Do this: make sure your key content is in the HTML at page load. Test it: view the page source and search for your key text.

Cover the whole topic. One AI question becomes many.
When someone asks a question, AI assistants perform a so-called fan-out: the question is split into several narrower sub-queries that are answered separately. A single search can trigger anywhere from a handful to twenty or so sub-queries. A cluster of focused pages covering the topic broadly gives you more chances to catch one of them.
Do this: map the questions your customers ask within your topic and cover them with a cluster of focused pages. One question per page usually beats one giant page about everything.
Fan-out is Google's own term for how AI Mode fans a question out into several sub-queries.

Build your name beyond your own site.
AI models learn about brands from the whole web: industry media, podcasts, forums, YouTube, LinkedIn and review sites. In Ahrefs' study of 75,000 brands, brand mentions were the factor that correlated most strongly with AI visibility, more than three times stronger than backlinks. Correlation is not causation, but the signal is clear.
Do this: ask ChatGPT and Perplexity which sources they cite in your industry. Then make sure you appear in the ones that matter most.

Show who is writing. Anonymous content has worse odds.
Credibility carries weight in both worlds. Named authors with a role, credentials and a real author page give LLMs a reason to trust your content, and to cite it.
Do this: where possible, give every important article a byline with name and title, linked to an author page with background and expertise. Show publication and update dates.
-
Keep content fresh. AI has a strong recency bias.
LLMs prioritize recently updated content. In Ahrefs' analysis of 17 million AI citations, the content AI cites was on average about 26 percent fresher than regular search results.
Do this: set up a quarterly routine to update your content (text, figures, years, examples and so on) on your most important pages. Ideally, display the update date clearly.

Own a data point nobody else has.
AI avoids citing generic content that exists on a hundred other sites. Your own data, such as a survey, a benchmark or statistics from your business, is the most citable thing you can publish. The industry calls this information gain. Whoever owns the number owns the citation.
Do this: publish an annual survey or an industry benchmark built on your own data. Give it a name people can refer to.
-
Measure your AI visibility, every month.
AI traffic is still small in volume, but several independent measurements suggest it often converts better than average organic traffic. What you do not measure, you cannot improve.
Do this: ask ChatGPT, Perplexity and Gemini your most important customer questions once a month and note whether and how you are mentioned. Segment AI referral traffic in GA4.
Note: AI answers vary between people, sessions and phrasings. Treat your own tests as an indication, not an exact measurement.
