Audit Your robots.txt
Open your robots.txt at yourdomain.com/robots.txt. Look for Disallow rules.
# Allow all AI crawlers User-agent: GPTBot Allow: / User-agent: ClaudeBot Allow: / User-agent: PerplexityBot Allow: / User-agent: Google-Extended Allow: /
Create an llms.txt File
Place an llms.txt file at your domain root. This emerging standard helps LLMs understand your site.
# My Company — Short description ## About We provide [what you do]. ## Key Pages - [Homepage](https://example.com/) - [About](https://example.com/about) - [Blog](https://example.com/blog) ## Optional - [Sitemap](https://example.com/sitemap.xml)
Check Meta Robots Tags
Ensure your pages don't have noai or noindex in their meta robots tags.
<!-- Good: allows AI indexing --> <meta name="robots" content="index, follow"> <!-- Bad: blocks AI crawlers --> <meta name="robots" content="noai, noimageai"> <!-- Bad: blocks all crawling --> <meta name="robots" content="noindex, nofollow">
Add a sitemap.xml
A sitemap helps AI crawlers discover all pages on your site.
# In robots.txt, add: Sitemap: https://yourdomain.com/sitemap.xml # Most CMSes auto-generate sitemaps: # WordPress: /sitemap.xml or /sitemap_index.xml # Shopify: /sitemap.xml # Next.js: use next-sitemap package
