Google Says You Don't Need llms.txt. Here's the Catch.
Google says llms.txt is unnecessary. Chrome Lighthouse audits it anyway. We fact-checked five studies on what llms.txt really does for AI visibility in 2026.
Also known as: YouTube Mention Tracker, YouTube Visibility Auditor, YouTube Coverage Checker
Tracks brand mentions across YouTube videos. Scores five dimensions on a 100-point scale (volume, channel diversity, reach, sentiment, recency). Sentiment is transcript-grounded for the top five videos by views, a GPT-4o-mini pass over the actual spoken content catches sarcasm and late-video reversals that title-only analysis misses. Concentrated negative coverage (two or more negative videos from a single channel) is flagged as an actionable recommendation. Live YouTube Data API queries and live transcript fetches on every audit, no cached snapshots.
