Common Mistakes

❌

Blocking AI crawlers without reasonBlocking GPTBot and ClaudeBot means your site won't be cited in AI responses.

❌

Not having llms.txtWithout llms.txt, AI systems don't get a summary description of your site for citation.

❌

Missing JSON-LD markupJSON-LD helps AI understand page type, author, publication date, and main topic.

Content only in JSMany AI crawlers don't execute JavaScript. Core content must be in HTML.

Best Practices

✓

Create llms.txtPlace a brief description, section list, and key pages at the site root.

✓

Allow AI crawlersWithout special reasons — don't block GPTBot, ClaudeBot, PerplexityBot in robots.txt.

✓

Add JSON-LD to all pagesMinimum: Organization, WebSite, BreadcrumbList — this improves AI understanding of structure.

✓

Keep llms.txt updatedWhen adding new sections, update llms.txt so AI systems know about new content.

How to Make Your Website Accessible to AI Crawlers and LLMs?

AI systems such as ChatGPT, Claude, Perplexity, and Gemini rely on crawlers — GPTBot, ClaudeBot, PerplexityBot — to index web content for training and retrieval. Providing a llms.txt file at the root of your domain helps AI agents quickly understand your site structure and key pages. Properly configured robots.txt, meta tags, and canonical URLs ensure your content is indexed correctly and cited accurately in AI-generated answers.
