How to get your brand named by AI assistants.
AI visibility is how often AI assistants name your brand when buyers ask about your category. This guide explains how ChatGPT, Perplexity, Claude and Google AI Overviews choose which brands to name, the four things that decide whether yours is one of them, what to skip, and a four-week plan to measure and fix it.

What changed when buyers started asking AI?
A search engine returns a page of links and lets the buyer choose. An AI assistant writes one answer and names a handful of brands in it. There is no page two: a brand that is not in the answer is not considered.
The answer is built from sources the buyer rarely opens. When we ran 20 category questions about our own market on four engines, the answers cited 387 different websites, and 43.5% of the citations were comparison pages: listicles, "alternatives" pages and "X vs Y" pages. Your own site is one voice among hundreds.

Same scan, brand questions, read by handWhat decides whether an AI engine names your brand?
Four things, and they gate each other in this order. Content work cannot help if a crawler cannot read the page, and a perfect page cannot help if the engine thinks you are a different company.
Can its crawlers read you?
The bots each engine sends must reach your pages and see real text, not an empty shell.
Does it know who you are?
The engine has to tell your company apart from others with similar names.
Are you on the pages it cites?
Comparison pages, review sites and lists decide most shortlists. You need to be on them.
And a fourth that runs through all three: answer the questions buyers actually ask.
Can AI crawlers read your site?
Each engine sends its own bots, and each can be allowed or turned away separately. The ones that decide whether you can appear in answers today are the search and user fetchers. The training crawlers decide what future models may learn.
| Engine | Bots that matter |
|---|---|
| ChatGPT | OAI-SearchBot, GPTBot, ChatGPT-User |
| Perplexity | PerplexityBot, Perplexity-User |
| Claude | ClaudeBot, Claude-SearchBot, Claude-User |
| Google AI Overviews | Googlebot, Google-Extended |
Two failures are common, and neither shows up when you look at your site in a browser.
- Blocked at the edge. A CDN's bot-blocking setting can return an error to AI crawlers even when robots.txt allows them. On 4 Oct 2026 our own site did exactly this: GPTBot and ClaudeBot got a 403 from the edge while robots.txt allowed every bot.
- Empty until JavaScript runs. If your text only appears after scripts execute, many bots see a blank page. The same day, a bot fetching our homepage saw 9 of its 2,416 words.
Check it yourself in five minutes
Fetch a key page as each bot and look at the status code and the words you get back:
curl -s -o /dev/null -w "%{http_code}\n" -A "GPTBot" https://yoursite.com/
curl -s -o /dev/null -w "%{http_code}\n" -A "ClaudeBot" https://yoursite.com/
curl -s -A "OAI-SearchBot" https://yoursite.com/ | sed 's/<[^>]*>//g' | wc -wA 403 or 503 means something is blocking that bot. A word count far below what you see on the page means your text depends on JavaScript. Fix the block at the CDN, and serve your main content in the HTML.
Does the AI know which company you are?
Before an engine can recommend you, it has to know which company you are. When a name is close to a better-known one, the model falls back on what it knows best.
It happened to us. Asked five questions about Proofsource by name, ChatGPT, Claude and Google AI Overviews described other companies, most often ProveSource, a social-proof popup tool with a similar name. Only Perplexity, which read our site live, got it right.
- Write one plain sentence that says what you are and who it is for. Put it at the top of your homepage, in your meta description and on every profile.
- Use one spelling of your name everywhere, including LinkedIn and review sites.
- Add Organization structured data with your official site and links to the profiles that confirm it.
- If you share a name with another company, say so plainly: one sentence that you are not them gives engines something to quote.
Which pages do AI engines cite, and how do you get on them?
For "best tool for X" questions, engines lean on pages that compare options: listicles, alternatives pages, versus pages and review sites. In our scan those were 43.5% of citations. Most of them are written by third parties, and many accept submissions or corrections.
- Ask each engine the buyer questions that matter most to your pipeline.
- List every page they cite, and mark which ones mention you.
- Sort the ones that do not by how often they are cited. Those are your targets.
- Pitch the authors with something useful: accurate facts, a fair comparison, a real customer.
- Publish your own honest comparison pages, with sources for every claim about other products. Engines discount pages that only flatter their author.
Our own comparison of AI visibility tools is written to that standard, weak spots included.
Which buyer questions should you track?
Track the questions a buyer asks before they know your name: "what is the best X for Y", "X alternatives", "X vs Y", "which X has a free trial". Those are where shortlists are made.
- Start small. Five or six topics with up to three questions each is enough to see the pattern. More questions are worth adding once you act on the first set.
- Keep brand questions separate. A question that names you will mention you whether or not the engine knows who you are, so it says little about visibility. Use it to check accuracy instead.
- Write them the way buyers do, in full sentences, with the constraints they care about: price, team size, integrations.
Why is one check not enough?
Ask the same engine the same question twice and you can get two different answers. One answer is a sample, not a fact, and a handful of samples can mislead.
The honest way to report a rate from a small sample is with an interval. Named in 6 of 20 answers is 30%, but the 95% Wilson interval runs from about 14.5% to 51.9%. At 60 of 200 it narrows to about 24.1% to 36.7%. A change only means something once it is bigger than the interval, so re-measure after every fix, on the same questions and engines.
The full method is on the methodology page, and the terms are in the glossary.
What should you skip?
- llms.txt as a ranking fix. It is a proposed file listing your key pages for language models. It is harmless, but Google says no special AI text files are needed for AI Overviews, and none of the engines we track has said it uses llms.txt for ranking.
- Special "AI markup". Google states there is no special schema.org markup you need for its AI features. Normal structured data still helps engines read you.
- Blocking training crawlers by reflex. It is a fair choice, but it means future models learn less about you. Decide it deliberately, and never block the search fetchers by accident.
- Fake reviews and planted mentions. They are against the rules of the sites engines trust most, and one exposed review can undo the rest.
What does a four-week plan look like?
- Week 1, baseline. Pick your questions, ask every engine, record who is named and what is cited. Run it twice, a day apart.
- Week 2, access. Check each bot against your key pages, fix CDN blocks and JavaScript-only content.
- Week 3, identity and sources. Publish your one-sentence definition everywhere, and pitch the five most-cited pages that leave you out.
- Week 4, re-measure. Ask the same questions on the same engines. Keep what moved beyond the interval; rethink what did not.
How does Proofsource help?
Everything above works with a spreadsheet and a fetch command. Proofsource does it on a schedule: it asks ChatGPT, Perplexity, Claude and Google AI Overviews your buyer questions every day on paid plans, records who is named and what is cited, puts a 95% interval on every percentage, checks crawler access, and drafts the fix for each gap for you to approve.

What people ask after reading this guide
How do I get my brand mentioned by ChatGPT and other AI assistants?
Work through four things in order: let their crawlers read your site, make it obvious which company you are, get onto the pages they cite for your category, and answer the questions buyers actually ask. Then measure on every engine, more than once.
How long does it take to show up in AI answers?
Engines that search the web live, such as Perplexity, ChatGPT search and Google AI Overviews, can reflect a change within days of a re-crawl. Answers built from a model's training change only when a new model ships, which can take months.
Is AI visibility the same as SEO?
It overlaps. AI engines draw on web pages and search indexes, so crawlability, clear pages and authority still matter. The outcome is different: being named inside one written answer rather than ranking on a page of links, and that outcome changes from run to run.
Do I need llms.txt to appear in AI answers?
No. Google says no special AI text files or markup are needed for AI Overviews or AI Mode, and none of the four engines Proofsource tracks has said it uses llms.txt for ranking. It is harmless to add, but it is not the fix.
Can I do this without a tool?
Yes, for a first look. Ask each engine your ten most important buyer questions, note who is named and which pages are cited, and repeat a few days later. A tool earns its place when you need to track many questions on several engines every day and tell real change from noise.
