Summary
Getting cited by Claude comes down to four things: letting Anthropic's search bots reach your pages, writing passages that answer one question clearly, earning mentions in the niche and trade publications Claude reads, and keeping key pages up to date. SEO for Claude builds on good SEO, but your Google ranking won't carry over automatically. Check your visibility in Claude directly, and keep testing.
Whether you’re comparing software, choosing a supplier or looking for a service, you no longer need ten open tabs. You can ask Claude, which searches the web, reads the pages and comes back with one answer, sources attached. Those few links are where your brand now needs to be seen. Claude SEO is how you earn that place. This guide explains how Claude chooses what to cite, and five steps to show up in Claude answers more often.
How Does Claude Find and Cite Sources?
Claude only cites sources when it searches the web. Otherwise, it answers from what it already knows from its training. With web search on, it looks up current pages and attaches citations to its answer. Those AI citations are built in. Anthropic’s web search documentation for developers says citations are always enabled for web search, and each one carries the page title, the URL and up to 150 characters of the cited text. In other words, Claude quotes a single passage, not your whole page, and that passage has to stand on its own, whether you’re a startup or a household name.Which Search Index Does Claude Use?
Anthropic hasn’t explained where Claude’s search results come from, and its developer documentation doesn’t name a provider. In March 2025, TechCrunch reported that Anthropic had added Brave Search to its list of data-processing partners, and that Claude’s search function contained a parameter called “BraveSearchParams.” A page that ranks well on Google isn’t automatically visible to Claude, so search for your most important pages on Brave Search and see whether they appear.Anthropic’s Three Bots at a Glance
Anthropic’s help article on how its crawlers work and how to block them lists three bots:| Bot | What it does | If you block it |
|---|---|---|
| ClaudeBot | Collects public content that may be used to train Anthropic’s models | Your future content is left out of training |
| Claude-SearchBot | Indexes content to improve search answers | May reduce your visibility in Claude’s search results |
| Claude-User | Fetches pages when a user’s question needs them | Claude can’t retrieve your pages for those questions |
Step 1: Make Sure Claude Can Reach Your Pages
Start with your robots.txt file. Anthropic says its bots follow robots.txt rules, and each subdomain needs its own file. Check that Claude-SearchBot and Claude-User aren’t blocked on any subdomain you want cited, such as your blog or help center. If you use a firewall or bot-protection service, ask your developer to confirm it isn’t turning Anthropic’s crawlers away. Anthropic publishes the IP addresses its bots use. Then look at how your pages load. Anthropic’s web fetch tool documentation says the tool doesn’t support websites rendered dynamically with JavaScript. If your pricing or FAQs only appear after scripts run, put that content in the page’s HTML.Step 2: Write Passages Claude Can Quote
This is the heart of how to optimize content for Claude. Every important section of your page should make sense on its own:- Lead with the answer. Put the direct answer in the first sentence under each heading, then add detail.
- Use question-style headings. Phrase them the way buyers ask, such as “How long does setup take?”
- Name your product or service. Use the product or service name rather than “it,” so a quoted line still makes sense.
- Swap vague claims for facts. Numbers, prices and timeframes give Claude something concrete to repeat. Our guide on getting your data and statistics cited by AI covers this in more detail.
| Hard to cite | Easy to cite |
|---|---|
| “We offer affordable plans for growing teams.” | “Plans start at ₹2,499 per user per month, billed annually.” |
| “Onboarding is quick and painless.” | “Most teams finish setup within five working days.” |
| “Our support team is always there for you.” | “Support runs 9 am to 9 pm IST, Monday to Saturday.” |
Step 3: Earn Brand Mentions in the Publications Claude Reads
What others say about you matters as much as what you say about yourself. Muck Rack’s analysis of how Claude cites media found that Claude’s 100 most-cited outlets have about 50% fewer average monthly visitors than ChatGPT’s top 100. Its conclusion: trade publications, industry-specific outlets and specialist reporters are even more valuable when it comes to Claude. For a B2B brand, that’s good news. A byline in an industry journal or a quote in a specialist newsletter can do more for Claude visibility than chasing national news coverage. Our post on E-E-A-T in the AI era explains why these credibility signals matter more now. Keep your brand details consistent everywhere. If your website and an old directory listing disagree, any AI tool reading both gets a muddled picture.Step 4: Keep Your Key Pages Fresh
The same research found Claude has a “citation sweet spot”. Claude cites news articles from the past 10 weeks most often, and it is about three times more likely than ChatGPT to cite one that is two to four weeks old. The study looked only at news coverage, but the takeaway for your website is the same: keep your key pages fresh. Review your most important pages on a set schedule, update facts as they change and show a visible “last updated” date.Step 5: Track Whether It’s Working
List 10 to 20 questions your buyers would ask, then run them in Claude with web search on. Note whether your brand appears, which page is cited and which competitors show up instead. Repeat the same questions over time, because AI answers can change from one session to the next. Your server logs help too. Visits from Claude-SearchBot and Claude-User show whether Anthropic’s systems are reaching your pages.

Claude SEO means making your content easy for Claude to find, understand and cite when it searches the web. It covers crawler access, clear writing, third-party mentions and regular updates. It sits under the wider practice of generative engine optimization (GEO), also called answer engine optimization or LLM optimization.
Anthropic hasn’t said which search provider powers Claude. TechCrunch reported in 2025 that Anthropic listed Brave Search as a partner, so a strong Google ranking alone doesn’t mean Claude can see your pages.
ClaudeBot collects content that may be used for training, while Claude-SearchBot and Claude-User handle search. Anthropic lets you block each one separately, so you can opt out of training and still allow search.
There’s no public evidence that it does, and Anthropic’s help article on its crawlers doesn’t mention llms.txt. Your time is better spent on the basics: letting Claude’s bots reach your site, writing clear answers and getting mentioned on trusted sites.
Yes. Claude cites specific passages rather than whole websites, and Muck Rack’s research shows it favors smaller, specialist outlets. A clear, factual page and a few trade mentions give a small business a fair chance to get cited by AI.
Both tools cite pages when they search the web, but each uses its own bots. ChatGPT finds sites for its search answers through OpenAI’s OAI-SearchBot, while Claude uses Claude-SearchBot and Claude-User. Make sure your robots.txt lets both sets in, and check your brand in each tool on its own.
Perplexity almost always searches the web and shows its sources with every answer. Claude shows sources only when it searches the web. Each tool sends its own bot to read your site, so allow PerplexityBot as well as Anthropic’s bots.
Not entirely. Gemini gets its results from Google Search, while Claude reportedly uses Brave Search. A strong Google ranking helps with Gemini but may not carry over to Claude. Clear, current content works for both, so test your pages in each.
