What is LLMs.txt Drift Monitor?

LLMs.txt Drift Monitor compares your current `/llms.txt` links with sitemap URL coverage to surface drift. It reports missing URLs, stale URLs, duplicates, and invalid link patterns.

Why it matters for AI SEO: When llms.txt drifts from real site structure, AI systems may prioritize outdated or incomplete paths. Coverage gaps reduce retrieval quality and citation consistency.

Release Monitoring: Run drift checks after content launches and template updates to ensure machine-facing URL guidance stays current.

Content Operations: Identify important sitemap URLs not represented in llms.txt and prioritize them for inclusion.

Quality Control: Catch duplicate or malformed links before they degrade crawler guidance quality.
