Claude

The technical-buyer AI you can't ignore

Claude (Anthropic) is the AI of choice for developers, technical buyers and professional-services teams. While its raw user count trails ChatGPT, its commercial-decision influence in B2B is disproportionately high.

Why Claude matters for B2B brands

Claude is overrepresented in technical workflows: code review, documentation lookup, comparison research for SaaS / dev tools, contract analysis. The buyer profile skews more senior and more technical than ChatGPT's. This means a Claude citation in a B2B context is often higher commercial value than a ChatGPT mention with similar content.

What's distinctive about Claude

**Explicit `llms.txt` support.** Claude reads and respects llms.txt. Shipping one signals which pages should be authoritative for your brand.
**Primary-documentation bias.** Claude prefers citing official docs over secondary articles. Make sure your `/docs/`, `/api/` and `/changelog/` are indexable and well-structured.
**Long-context reasoning.** Claude pulls broader context windows than other engines, meaning it can use longer pages effectively. Don't over-truncate.
**Conservative on hallucination.** Claude is more likely to say „I don't know" than to fabricate, which means thin entity presence shows up as absence rather than wrong information.

Optimisation playbook

Allow `ClaudeBot` and `anthropic-ai` in robots.txt.
Ship a `/llms.txt` curating your authoritative pages.
Maintain `/docs/` with clear hierarchy and Article / TechArticle schema.
Add Person schema to author profiles, link to LinkedIn and academic citations where applicable.
Test: ask Claude direct questions about your brand, your features, your pricing. Where it says „I don't know", that's a presence gap.

FAQ

Does Claude have a search function?

Claude can browse the web in some surfaces (especially the API + Claude.ai with the right configuration). Default Claude relies more on training data than ChatGPT's default.

Should I prioritise Claude over ChatGPT?

Depends on audience. For B2C / mass-market, ChatGPT is bigger. For B2B-technical, Claude is often higher-value per impression. Most brands should optimise for both.

What is `llms.txt` again?

A markdown file at `/llms.txt` declaring your canonical content pages for AI consumption. Anthropic Claude has explicit support — see our llms.txt guide for the spec.
