For its first years, Claude answered only from what it had learned during training, which meant it could not tell you anything about last week. That has changed. Claude now searches the live web to answer current questions and cites the sources it uses, which turns it into another place your B2B brand can be named or missed.
Here is the part most teams miss: Claude's web search does not run on Google's index or Bing's. It uses a different search engine underneath, which means appearing in Claude is a separate job from ranking on Google, and one your competitors are probably not doing yet. This guide covers what Claude web search is, how it finds and cites sources, and a step-by-step approach to appearing in it as a B2B brand.
What Claude web search is, and where buyers meet it
Claude is Anthropic's AI assistant. When you ask it something that needs current information, it can run a live web search, read the results, and answer with cited links rather than relying only on its training. Like other answer engines, the output is a written answer with sources, not a page of ten blue links.
Buyers meet it in a few places: the Claude apps and claude.ai, where professionals use it for research and analysis; through the Claude API, where companies build it into their own products; and in Research mode, an agentic setting where Claude runs many searches and reasons across them before producing a longer, sourced answer. Research mode is the one that matters most for considered B2B purchases, because it is built for exactly the multi-step comparison a buyer does when evaluating vendors.
How Claude finds and cites its sources
You cannot optimize for a system you cannot picture, so start with the mechanism.
Claude blends what it already knows with a live web search, then cites the pages it used.
Claude answers from two pathways. The first is its training knowledge, which is broad but has a cutoff and cannot be optimized for directly. The second is live web search, which it uses for anything current, and which is where visibility is actually won. When Claude searches, it expands your question into several related searches rather than matching one string, the same retrieval-and-generation pattern behind how AI search works across engines, then writes an answer that cites the pages it drew from with footnote links.
Two things are worth knowing about how that search runs. First, Claude's web search is powered by Brave's independent search index, not Google or Bing, so being findable in Brave is the foundation for being cited by Claude. Second, Anthropic runs its own web crawlers, including one that indexes pages for Claude's search, so if your robots file blocks them, you remove yourself from consideration.
It helps to know these are not one crawler but a few, each with a different job. Anthropic documents a training crawler that gathers data to improve the models, a crawler that fetches a page when a user's prompt asks Claude to look at it, and a search crawler that indexes pages so Claude can find them during web search. For visibility, the search crawler is the one that matters: block it and you are absent from Claude's results, whatever your Google standing. Some teams block the training crawler for their own reasons, which is a fair choice, but blocking the search crawler by accident is the costly mistake. Check them separately in your robots file.
What makes Claude different: the Brave index
Every AI engine reaches for a different source, and Claude's is the one almost no marketing team has ever optimized for.
Because Claude's web search sits on Brave's index, your Google rankings do not carry over. A page that dominates Google can be absent from Brave, and therefore invisible to Claude, simply because no one ever checked. That sounds like a problem, but for a B2B brand willing to do the work it is an opening: the competition for Brave visibility is a fraction of the competition for Google, so the same content effort goes further.
There is a second trait worth planning for. In practice, Claude tends to cite a relatively large number of sources per answer and leans heavily on reputable, independent third-party coverage rather than only brand-owned pages. Trade publications, expert write-ups, and credible reviews carry real weight in what Claude surfaces. So appearing in Claude is partly an on-site job and partly a reputation job.
To make it concrete, picture a buyer asking Claude to compare the leading vendors in your category. To answer, Claude searches, pulls a handful of sources from Brave's index, and weighs them. If your product page is findable in Brave and a respected trade publication has written about you, you can land in the answer with two supporting citations. A competitor with a stronger Google presence but no Brave visibility and no independent coverage gives Claude nothing to pull, and is simply left out. Same question, and the brand that did the Brave-and-reputation work wins a citation the bigger competitor never sees.
Why Claude matters for B2B
Three reasons this surface is worth attention.
Its users are your buyers. Claude has strong adoption among professionals, technical teams, and enterprises, the people who research and approve B2B purchases. Being the brand Claude names for them is high-intent visibility, not general traffic.
The index is uncontested. Because so few teams optimize for Brave, the brand that does can appear in Claude ahead of larger competitors who out-rank it on Google. This is one of the clearest first-mover openings in AI visibility right now.
It rewards genuine authority. Claude's lean toward independent, reputable sources means the authority and trust signals you build, real expertise, credible third-party coverage, cited evidence, pay off directly. The work compounds with everything else in AI search optimization.
The playbook: how to appear in Claude web search
The work splits into three layers: be findable in the index Claude uses, be answer-ready on the page, and be well-regarded off-site.
1. Get findable in Brave. This is the foundation nobody checks. Confirm your key pages are indexed in Brave Search and see how you rank there for your priority buyer questions. If Brave does not surface you, Claude has little to pull. This is the Claude-specific equivalent of the ranking work that feeds Google's AI surfaces and Microsoft Copilot's Bing-based search.
2. Do not block Anthropic's crawlers. Check your robots file and make sure you are not blocking the crawlers Anthropic uses to index pages for Claude's web search. A single disallow line can quietly remove you from the running.
3. Lead with a clear, quotable answer. Claude lifts and summarizes, so front-load each section with a self-contained answer, then add the detail. The content formats that get quoted across AI search, real headings, direct answers, comparison tables, clean structure, apply here too.
4. Give it specifics to cite. Claude favors content with concrete substance: named entities, specific data, comparison tables, and clear attribution. Vague, generic pages give it little to quote. Concrete, well-sourced pages give it a reason to name you.
5. Build independent, reputable coverage. Because Claude leans on third-party sources, being written about credibly matters as much as what you publish. Earn coverage in trade publications, expert roundups, and reputable reviews, and reinforce it with strong E-E-A-T and trust signals on your own site. This is also how AI engines decide which brands to trust.
6. Cover topics in depth for Research mode. Because Research mode reads across many sources for comparison questions, thorough content that genuinely covers a topic and its follow-ups has more surface area to be pulled in than a thin page.
Pulled together, these are the fundamentals of answer engine optimization pointed at a new index. The strategy is familiar; the target is not.
How Claude compares to other AI engines
The clearest way to hold the AI-visibility problem in your head is that each engine answers from a different source, so each is a separate job.
Being cited is not one job: each engine's answers come from a different source.
Google's AI surfaces feed on Google's index, Copilot feeds on Bing, Claude feeds on Brave, and Grok reads the web plus real-time posts on X. The content fundamentals transfer across all of them, but the indexing and reputation work has to be checked engine by engine, because being strong in one says little about the others. It is also why the same question can produce different cited brands on each engine, the citation variability that makes AI visibility a spread rather than a single number.
How to track your Claude citations
Claude is easy to overlook because its search sits quietly inside a chat, so build a simple, repeatable check.
- Run your priority buyer questions in Claude, with web search on and in Research mode, and record whether you are cited, who is cited instead, and which pages it pulls.
- Check your Brave visibility alongside it, since a Claude gap often traces back to being absent from Brave. That tells you whether the problem is the index or the page.
- Track over time and against competitors. Watching who appears beside you turns tracking into competitive intelligence, and deciding your visibility metrics up front keeps it honest. Because a single manual check is noisy, frequent automated checks tell you more.
Where B2B teams go wrong with Claude
- Assuming Google strength carries over. Claude uses Brave, so a strong Google presence does not guarantee you appear. The index work is separate.
- Accidentally blocking Anthropic's crawlers. A restrictive robots file can remove you from Claude entirely without anyone noticing.
- Ignoring third-party coverage. Because Claude leans on independent sources, an on-site-only strategy underperforms. Reputation is part of the job.
- Publishing thin, generic pages. Claude cites specifics. Vague content gives it nothing concrete to quote.
- Never checking. Claude answers move and its search is invisible unless you look, so a one-time check tells you little about your real presence.
Frequently asked questions
Does Claude have web search? Yes. Claude can search the live web to answer current questions and cites the sources it uses. It still also draws on its training knowledge, but for anything recent it runs a live search.
What search engine does Claude use? Claude's web search is powered by Brave's independent index, not Google or Bing. That is why appearing in Claude is a separate task from ranking on Google, and why checking your Brave visibility matters.
How do I get my brand cited by Claude? Be findable in Brave for your priority questions, make sure you are not blocking Anthropic's crawlers, lead with clear and specific answers on well-structured pages, and earn reputable third-party coverage, which Claude leans on heavily.
Is optimizing for Claude the same as SEO? The fundamentals overlap: clear, authoritative, well-structured content wins. The difference is the index. Claude draws on Brave, so the indexing and ranking checks have to be done there specifically, not just on Google.
What is Claude's Research mode? Research mode is an agentic setting where Claude runs many searches, reads across sources, and reasons before producing a longer, cited answer. It suits the deeper comparison questions B2B buyers ask, so depth of coverage pays off there.
Where to start
Do the check almost no competitor has done. Search your five most important buyer questions in Brave and note whether you appear, then run the same questions in Claude with web search on and see whether you are cited. If you are missing from Brave, that is your first fix; if you are in Brave but not cited by Claude, the gap is answer-readiness or reputation. Either way, you will know where to start while the surface is still uncontested.
