What is Claude AI and why should you optimise for it?

Claude is an AI assistant built by Anthropic that uses web search and retrieval to find and cite sources when answering user questions. Unlike traditional search engines that return a list of links, Claude synthesises information from multiple web sources into a direct answer and provides inline citations to the pages it referenced.

Claude AI is Anthropic's AI assistant that uses web search and retrieval to generate cited answers. When Claude searches the web, it selects sources based on entity authority, factual accuracy, structured data, and content clarity. Optimising for Claude means structuring your content so it is selected as a cited source when users ask questions relevant to your industry. Claude processes billions of queries and represents a significant and growing source of brand visibility for businesses with well-optimised content.

Claude differs from other AI platforms in important ways. It places greater emphasis on entity authority and factual accuracy when selecting sources. Claude aggressively strips marketing language, meaning content must be written in direct, factual terms to be cited. Anthropic's ClaudeBot crawler indexes web content for Claude's retrieval system, and respecting robots.txt means ClaudeBot will only access content it is permitted to crawl.

For businesses, Claude represents a growing channel for brand visibility. As AI search adoption accelerates, being cited by Claude when users ask industry-relevant questions is becoming as important as ranking on traditional search engines. The techniques for earning Claude citations overlap with broader GEO (Generative Engine Optimisation) practices but have distinct requirements around entity signals, structured data, and crawler configuration.

Ranking Factors

What makes content get cited by Claude?

Claude evaluates these factors when deciding which sources to cite in its responses. They are ranked by their weight on citation selection.

Very High

Entity authority

Claude prioritises content from recognised entities with consistent information across the web. Businesses with established presence on third-party platforms (LinkedIn, Crunchbase, industry directories), consistent NAP (name, address, phone) data, and verifiable history are treated as more authoritative sources.

Very High

Factual accuracy and attributions

Claude values content that presents verifiable facts with clear attributions. Statements backed by data, references to official sources, and citations to academic research or industry publications are preferred. Claude cross-references claims against other sources, so accuracy directly affects citation likelihood.

High

Structured data (JSON-LD)

Comprehensive schema markup helps Claude understand entity relationships, content types, and authorship. Organization, Article, Person, FAQPage, and Service schemas provide machine-readable signals about what your site covers. Claude processes pages with structured data more effectively than unstructured content.

High

Direct, factual language

Claude strips marketing fluff. Phrases like 'industry-leading' or 'world-class' are ignored. Content written in direct, factual language with specific claims ('founded in 2022', 'serving 500+ clients', '20 years of experience') is far more likely to be cited than promotional copy.

High

Topical depth and coverage

Sites with comprehensive content clusters covering a topic in depth are cited more frequently than sites with a single surface-level page. Claude recognises topical authority through multiple interlinked pages that cover different aspects of a subject area.

Medium-High

Content freshness

Claude weights recent content more heavily for queries where timeliness matters. Pages with visible publication dates, regular updates, and current statistics have an advantage. A page updated in 2026 is preferred over one from 2023 for most queries.

Medium-High

Question-answer formatting

Content structured with question-format headings followed by direct, concise answers is highly citable. Claude extracts specific passages from pages, so every section should open with a clear factual statement that can stand on its own.

Essential

ClaudeBot accessibility

Your content must be accessible to ClaudeBot (Anthropic's web crawler). Ensure your robots.txt allows ClaudeBot, your content is publicly accessible (not behind authentication), and pages are server-side rendered. If ClaudeBot is blocked, Claude cannot index or cite your content.

How does Claude compare to ChatGPT and Perplexity for citations?

The key differences are in how each platform crawls, retrieves, and cites web content. Claude uses ClaudeBot and emphasises entity authority and structured data. ChatGPT uses Bing-based browsing with inconsistent citations. Perplexity always cites sources with inline links and weights domain authority heavily. Each platform requires a slightly different optimisation approach, though strong factual content with comprehensive schema markup benefits all three.

Step by Step

How to optimise your content for Claude AI: 8 steps

01

Audit your Claude visibility

Query Claude with your 10-20 most important keywords. Document whether your brand appears in responses, which competitors are cited, and what type of content earns citations. Test both simple factual queries and complex industry questions. This baseline reveals your starting position and highest-priority gaps.

02

Create entity-rich content

Produce comprehensive content that clearly establishes your brand as a recognised entity. Include consistent business details (name, location, founding date, leadership), link to authoritative third-party profiles (LinkedIn, Crunchbase, industry directories), and present verifiable facts rather than marketing claims. Include 15-30 external citations per page from reputable sources.

03

Implement comprehensive schema markup

Add Organization, FAQPage, Article (with author and date), Person, and Service schemas as JSON-LD. Schema helps Claude understand your content structure, entity relationships, authorship, and topical focus. Complete schema profiles improve your chances of being selected as an authoritative source.

04

Structure content for AI extraction

Claude extracts specific passages from pages. Structure your content so each paragraph makes one clear, self-contained point. Use question-format headings, lead with direct factual answers, and avoid paragraphs that require context from other sections to make sense. Include definitions for key industry terms.

05

Build topical authority clusters

Create 5-10 interlinked pages covering different aspects of your key topics. Claude recognises sites with deep topical coverage. A site with comprehensive coverage of a subject is more likely to be cited for any individual query within that topic. Each page should cover a specific subtopic in depth.

06

Allow ClaudeBot in robots.txt

Add 'User-agent: ClaudeBot' followed by 'Allow: /' to your robots.txt file. ClaudeBot is Anthropic's web crawler that indexes content for Claude's web search and retrieval. Without this, Claude cannot access your pages. Also verify that your content appears in your sitemap and is not gated behind authentication.

07

Create an llms.txt file

Add an llms.txt file to your site root directory. This file provides AI models with a structured summary of your site including your organisation name, description, key pages, and important content. Use the standardised llms.txt markdown format with headings, descriptions, and links to your most important pages.

08

Monitor and iterate

Query Claude monthly with your target keywords to track citation changes. When you see competitors cited instead of you, analyse their content to identify what they provide that you do not. Check your server logs for ClaudeBot crawl activity. Adjust your content, schema, and authority signals based on what works.

What are the best practices for Claude AI content?

Write for facts rather than marketing, establish entity consistency across platforms, include clear definitions for industry terms, use comparison tables, add visible publication dates, and keep your best content publicly accessible to ClaudeBot. Claude strips promotional language and prioritises verifiable, factual content with strong entity signals and clean structure.

Write for facts, not marketing

Claude aggressively strips promotional language. Statements like 'industry-leading' or 'best-in-class' are ignored entirely. Replace them with verifiable facts: '20 years of experience', 'serving 500+ clients', 'based in Sydney since 2022'. Specific, measurable claims are far more citable.

Establish entity consistency

Ensure your business name, description, and key details are consistent across your website, LinkedIn, Google Business Profile, Crunchbase, and industry directories. Claude cross-references entity information across sources. Inconsistencies reduce confidence in your authority.

Include clear definitions

When using industry terminology, define it clearly. Claude frequently cites pages that provide clean definitions. A sentence like 'GEO (Generative Engine Optimisation) is the practice of optimising content for AI search engines' is highly citable.

Use comparison tables

Claude frequently cites structured comparisons. Tables comparing products, services, features, or approaches are particularly effective because they provide dense, scannable, factual information that is easy for AI models to extract and reference.

Add publication and update dates

Include visible publication and last-modified dates on your pages. Claude uses these signals to assess content freshness. Include dates in both human-readable format and in your Article schema markup's datePublished and dateModified fields.

Keep authoritative content public

Claude cannot access authenticated content. If your best content is behind a login, paywall, or requires JavaScript authentication, Claude will never cite it. Make your most authoritative, entity-establishing content publicly accessible and crawlable by ClaudeBot.
