Claude and AI Assistants

Claude is an AI assistant made by Anthropic, and like other AI assistants it can search the web, read pages and cite sources in its answers. For site owners, this means your content can reach people through conversations as well as search results, if it is accessible and easy to understand.

How AI assistants use web content

AI assistants such as Claude, ChatGPT, Gemini and Copilot draw on information in two main ways:

  • Training data: the large language model learns general knowledge from a large body of text before release. This knowledge has a cut-off date.
  • Live retrieval: when web search is available and switched on, the assistant searches, reads relevant pages and writes an answer with citations. This keeps answers current.

Claude gained web search in 2025, and when it uses it, answers include links to the sources it relied on. Assistants can also read a specific URL a user shares, or work through tasks using several pages in a row, which is sometimes called agentic search.

Anthropic’s crawlers

Anthropic’s documentation describes separate bots for different jobs, a pattern shared by most AI companies:

  • ClaudeBot: collects public web content that may be used for model training.
  • Claude-SearchBot: helps improve the quality of search results.
  • Claude-User: fetches pages when a user’s question needs them.

Each can be managed separately with your robots.txt for AI bots. Blocking the search or user bots may reduce how often your pages can be read and cited. Check the provider’s current documentation, as names and behaviour can change.

How to make your site useful to assistants

  1. Keep key content in plain HTML. Many AI fetchers do not run JavaScript fully, so text that only appears after scripts load may be missed. See JavaScript SEO.
  2. Answer clearly and early. State the answer, then the detail. Assistants often quote or summarise the clearest passage.
  3. Be specific. Prices, dates, locations, steps and named examples are more useful than general claims.
  4. Keep facts consistent. Make your company name, services and details match across your site and profiles.
  5. Show who is behind the content. Author names, credentials and sources support trust.
  6. Earn independent mentions. Reviews, press coverage and community discussions help assistants form an accurate picture of your brand.

Measuring visibility in assistants

There is no Search Console for AI assistants. Practical options include asking your most important customer questions in each assistant regularly, recording whether you are mentioned or linked, and tracking AI referral traffic in analytics, for example visits from claude.ai. Results differ between users and sessions, so review trends over time.

Common misunderstandings

  • Assistants do not all share one index. A page cited in one tool may not appear in another.
  • Training data is not updated daily, so recent changes show up through live search rather than the model’s built-in knowledge.
  • Being mentioned is not guaranteed by any single tactic. Clear, trustworthy, accessible content gives you the best chance.
