Claude

Claude is an AI assistant developed by Anthropic, known for its reasoning ability, safety-focused design, and large context window. Recently, Claude has gained web search and tool use capabilities, allowing it to find, analyse, and cite web content. This makes Claude a relevant platform for content visibility alongside ChatGPT and Perplexity.

What is Claude?

Claude is an AI assistant built by Anthropic, a safety-focused company founded by former OpenAI members. Since launching in 2023, it has become known for strong reasoning, a massive context window capable of processing long documents, and a focus on being helpful, harmless, and honest. Recent updates have introduced web search and tool use, allowing the model to invoke external APIs, search the web, and analyse retrieved data.

Claude is increasingly used for research, coding, and complex content analysis. The addition of tool use is particularly significant for discoverability. Unlike standard chat interfaces, Claude can actively retrieve information rather than relying solely on its training data. This shift transforms it from a static knowledge base into a dynamic research agent capable of verifying current information.

How Claude Finds Web Content

Claude's discovery mechanisms are unique among major AI platforms. It employs a tool-based approach rather than a purely integrated search model. It can invoke web search APIs to find information, use external tools to retrieve and analyse content, and access "computer use" capabilities to control web browsers. This flexibility means Claude can discover content through multiple paths: direct search queries, API integrations, or direct browser navigation.

Navigability is critical. Wayfinder's research across 3,348 AI navigation tasks shows that 91% of successful navigation completes within two clicks. Furthermore, position in the DOM often matters more than semantic relevance. If your site requires complex navigation or obscures content behind heavy JavaScript without clear semantic structure, Claude may struggle to access it. Sites that are easily searchable and well-navigable are more likely to be found and utilised by Claude's tool suite.

Claude's Citation and Attribution Behaviour

Citation behaviour varies depending on how Claude discovers information. When conducting research, Claude typically cites sources, but the format depends on the discovery method. Information found via web search tools may appear as direct URLs, while data retrieved through APIs might lack standard linking. Attribution also relies on the clarity of the source page.

Claude's safety training emphasises accurate attribution, encouraging it to reference where information originates. For content creators, this means visibility is not just about ranking high in search results but ensuring content is extractable. If your page is discoverable but difficult for the AI to parse, accurate citation becomes less likely. You must ensure your content is clear and structured so Claude can confidently extract and attribute it during its research process.

Claude vs. ChatGPT vs. Perplexity: Discovery Models

Understanding the differences in discovery architecture helps tailor optimisation strategies. ChatGPT Search uses an integrated real-time search function where results directly inform conversational answers. Perplexity operates on a search-first design, where every response begins with a web search query.

Claude differs by using a tool-oriented, flexible approach. Web search is invoked via tools rather than being permanently embedded in the conversational flow. This gives Claude more agency in deciding when to search, but it also means discovery depends on the model's explicit decision to access external tools. This distinction affects how content is found; you may need to optimise for tool-based retrieval rather than just standard search intent.

Computer Use: The Next Frontier

Claude's "computer use" capability represents a significant shift in discovery. It allows the AI to control a web browser, navigate pages, click links, and interact with interfaces directly. This moves discovery beyond search-based queries to interaction-based browsing, mimicking human user behaviour.

This change has implications for technical SEO. JavaScript-rendered content becomes more accessible, but bot detection mechanisms may block access. Research indicates that most AI assistants operate on a search-first model where they search for a result and then visit the site to verify content matches the query. As computer use matures, Claude may bypass traditional search results entirely, relying on direct navigation. Optimising for this future state requires ensuring your site is navigable by an autonomous agent, not just readable by a crawler.
