How Claude picks its sources

  1. Your question

  2. Web search

  3. Pages Claude may read

  4. Answer with sources

Sample data

  • Claude searches the web and shows its sources

    Claude can search the internet for up-to-date information. According to Anthropic, every answer it gives this way includes citations, so you can check for yourself where the information comes from.1

  • Claude-SearchBot serves the search results

    Claude-SearchBot navigates the web to improve the quality of search results in Claude. Block that bot and, according to Anthropic, your site may be less visible and less accurately represented in those results.2

    robots.txt
    User-agent: Claude-SearchBot
Allow: /

  • Training is a separate choice

    ClaudeBot collects content that could contribute to model training. Block ClaudeBot and, according to Anthropic, your future material is excluded from training. Claude-SearchBot has its own rule. So you can refuse training and still stay readable for search.2

    robots.txt
    User-agent: ClaudeBot
Disallow: /

  • A user question goes through Claude-User

    Claude-User fetches a page when someone asks Claude a question that needs it. Block that bot and Claude cannot retrieve your content for such a question. Claude-User follows robots.txt too.2

What Atlas checks

Atlas reads your robots.txt separately for Claude-SearchBot, Claude-User and ClaudeBot and keeps search, user questions and training apart. Then Atlas checks the pages Claude could show as a source.

What we do to your website

  • The questions behind a purchase

    We find out which questions customers ask an assistant before they buy, and which pages are missing for them.

  • Pages worth citing

    We build pages with concrete facts: sizes, materials, delivery time and terms. An answer should be able to take a correct sentence from them, with your page as the source.

  • Access and technical setup

    Atlas checks whether Claude-SearchBot and Claude-User may read and whether titles, content and product data are in the HTML.

  • Honest about measuring

    We do not check Claude answers by hand at the moment. Claude is not in any plan, nor in our free scans. You do get the check of the Claude crawlers and the work on your pages.

Which plan fits

Claude is not in any plan right now: we do not check Claude answers by hand. We do the work on your pages and the technical setup in every plan, and Claude can read those pages too if Claude-SearchBot is allowed.

FAQs

Answers to the questions business owners ask us most.

Which crawlers does Claude use?

Anthropic names three. Claude-SearchBot navigates the web for the search results in Claude. Claude-User fetches a page when a user asks Claude something that needs it. ClaudeBot collects content that could contribute to model training. All three follow robots.txt, so you set each one with its own rule.

Can I refuse training by Claude and still be found?

Yes. Training and search run through different bots. With a rule that blocks ClaudeBot, your future content stays out of training, according to Anthropic. Claude-SearchBot and Claude-User each have their own rule, which you can leave in place. If you do block those two, your site may be less visible in Claude, according to Anthropic.

Which websites does Claude use as sources?

When Claude searches the web, the pages it used are listed as citations with the answer. Claude decides which ones. Pages that answer a question fully and verifiably, with the key text in the HTML and a robots.txt that allows Claude-SearchBot, stand a better chance. Nobody can guarantee a mention.

Which search engine does Claude use?

That is not in Anthropic’s public documentation. What is known is that Claude-SearchBot navigates the web to improve the search results in Claude. A good position in one search engine does not cover Claude automatically. Make sure Claude-SearchBot may read your pages.

Does Outseen track what Claude says about my business?

No, not at the moment. Claude is not in any of the plans, and our free scans do not measure Claude either. We do use Atlas to check whether the Claude crawlers may read your pages, and we work on the content Claude can use as a source.

Can I block the Claude bots by IP address?

We advise against it. According to Anthropic, blocking by IP address may not work correctly and does not reliably keep you out. It can also stop the bots from reading your robots.txt. Use robots.txt instead, with a rule per bot. If you only want to slow the visits down, Anthropic also follows the Crawl-delay rule.
