How to get found in Claude: how Anthropic’s AI finds your content

Claude is Anthropic’s AI assistant and it is growing fast as an alternative to ChatGPT and Google Gemini. Millions of people ask Claude questions every day, about products, services, strategies and recommendations. If your business is not visible in Claude’s answers, you are missing a growing channel.

The bigger picture across all platforms is called AI visibility.

But how does Claude decide which sources to cite? And what can you do to appear in them? This article explains how Claude’s web search works, what Anthropic’s crawlers do and which steps you can take to become findable.

How Claude’s web search works

From language model to search assistant

At its core, Claude is a large language model (LLM). It was trained on large amounts of text and learned patterns in language, facts and reasoning. But a language model on its own has no access to current information; it only knows what was in its training data.

With web search, that changed. When a user asks a question that needs current information, Claude can search the web and fetch relevant sources. The answer is then put together from those sources, with references.

That makes Claude comparable to Perplexity or Google AI Mode: it gives a compiled answer with sources. But the way Claude selects sources differs.

Anthropic’s approach: accuracy first

Anthropic puts a strong focus on safety and reliability. That shows in how Claude handles sources:

• Source quality over quantity. Claude would rather cite three reliable sources than ten doubtful ones.
• Transparency about uncertainty. If Claude does not find enough reliable information, it says so instead of guessing.
• Minimizing hallucinations. Anthropic invests heavily in techniques to keep Claude from making things up.

For businesses this means: when Claude cites your content, that is a strong signal of trustworthiness.

Anthropic’s crawlers

Anthropic has several user agents, not one

This is where most robots.txt files fall short: they only filter on ClaudeBot, while Anthropic visits with several user agents. They do different things, and blocking them does different things.

User agent	When it visits	What blocking it means
ClaudeBot	Crawls broadly to collect content for Anthropic’s models	Your future content is left out of that collection
Claude-User	Fetches a page because a user asks Claude about it right then	Claude cannot open your page when someone explicitly asks for it
Claude-SearchBot	Feeds the search function Claude uses to select sources	You do not qualify to be cited as a source
anthropic-ai	An older agent name you still see in logs and existing robots.txt files	Mainly relevant for complete log analysis

The distinction that matters is the one between ClaudeBot and the other two. If you allow only ClaudeBot and forget the rest, you can still be invisible at the moment a user asks Claude a concrete question. That is exactly the moment you care about.

So list them explicitly in your robots.txt:

User-agent: ClaudeBot
Allow: /

User-agent: Claude-User
Allow: /

User-agent: Claude-SearchBot
Allow: /

User-agent: anthropic-ai
Allow: /

If you do not want your content used for training, you can block ClaudeBot while keeping Claude-SearchBot and Claude-User allowed. Then check your server logs for all names, not only ClaudeBot. If you see ClaudeBot but never Claude-SearchBot, you are crawled but not selected as a source, and that is a very different problem with a very different solution.

Claude’s crawlers versus other AI crawlers

Crawler	Company	Purpose
ClaudeBot	Anthropic	Model training
Claude-SearchBot	Anthropic	Search in Claude
GPTBot	OpenAI	Model training
OAI-SearchBot	OpenAI	Search in ChatGPT
Google-Extended	Google	Gemini training and grounding
PerplexityBot	Perplexity	Perplexity’s search index

Each of these needs its own permission in your robots.txt. If you want to be findable in all AI search engines, allow the search bots of each. The broader strategy is in getting found in AI search engines, and the full bot overview in how AI crawlers read your site.

Which sources Claude cites, and how

Source selection: quality as a filter

When Claude searches, it fetches several web pages. But not every page found gets cited. Claude weighs:

• Source authority. Established, well-known sources get more weight.
• Relevance to the question. The content must answer what the user asks directly.
• Consistency with other sources. Information confirmed by several reliable sources gets priority.
• Freshness. For time-bound questions Claude prefers recent information.

What citations look like

Claude shows sources as citations in the answer, linking to the original page. Compared with Perplexity, Claude generally cites fewer sources per answer. That makes each citation relatively valuable: every mention is a deliberate choice by the model.

How Claude differs from ChatGPT and Perplexity

Compared with ChatGPT

• ChatGPT cites more broadly. It often shows more sources per answer.
• Claude weighs source quality heavily. Anthropic’s focus on reliability means stricter filtering.
• Training data differs. The underlying knowledge of Claude and ChatGPT comes from different datasets, so they have different frames of reference.

Compared with Perplexity

• Perplexity searches more aggressively. Almost every answer contains several sources.
• Claude is more selective. Not every question leads to a web search; Claude uses its trained knowledge first.
• Perplexity cites niche sources more often. Because of the large number of citations, smaller websites come into view faster in Perplexity.

What this means for your strategy

Claude’s selectivity means your content has to meet a higher bar to be cited. It is less about “being everywhere” and more about “being the most reliable source on a specific topic”. The basic principles are in what is GEO.

Practical steps for Claude

1. Make sure Claude’s crawlers can reach your site

Check your robots.txt, your firewall and your CDN. Without crawl access, your content does not exist for Claude.

2. Write content that answers questions directly

• Start paragraphs with the answer, not an introduction.
• Use concrete numbers, examples and facts.
• Avoid vague wording; be specific.

A page that starts with “In this article we discuss…” does worse than a page that starts with “The average conversion rate for B2B landing pages is 2.6 percent.”

3. Build authority in your field

• Publish consistently on your core topic.
• Get mentioned on other trusted websites (trade publications, industry associations, partners).
• Show author information on your content: who wrote this and why is that person an authority?

4. Use structured content

• Use H2 and H3 headings that summarize the content.
• Put key facts in lists or tables.
• Use schema markup (JSON-LD) for organization information and article data.

5. Be the primary source

Claude prefers original sources over derived content. If you do your own research, have your own data, or are first to cover a topic, your chance of being cited goes up:

• Publish your own benchmarks or market research.
• Write case studies with specific results.
• Be the first to cover a new topic in your niche.

6. Keep content current

For time-bound questions Claude prefers recent content. Update your most important pages regularly with current numbers and insights. A page about “Trends for 2024” has little value in 2026.

7. Keep it technically accessible

• Make sure your pages load fast.
• Avoid content that only appears after JavaScript runs; AI crawlers do not run it.
• Keep a clear sitemap with your most important pages.

Claude’s growing role in search

Claude is no longer only a chatbot for productivity tasks. With web search it is becoming a real search platform, and Anthropic keeps expanding what Claude can do. As with SEO ten years ago, starting early gives a head start that is hard to catch up with later.

Summary

Getting found in Claude comes down to three principles:

1. Give access. Make sure Claude’s search and user bots can crawl your content.
2. Offer quality. Write content that is reliable, specific and directly relevant.
3. Build authority. Be the most credible source in your field.

Claude is more selective than many other AI platforms. That makes it harder to appear, but also makes each citation more valuable. For the complete picture, read getting found in AI search engines.
