YouTube channel audit
Paste a public channel. Creator Climb scores recent uploads from public metadata, then can write three fixes tied to specific videos. No login for the scan.
What this audit uses
The scan reads public titles, descriptions, tags, durations, and publish dates. Scores flag short or cut-off titles, thin descriptions, missing chapters on long videos, and too many hashtags. Priority is an estimate from those issues and public view counts. It is labeled as an estimate because impressions and click-through rate are not in the public API.
Read the longer checklist in the channel audit guide, or compare this with keyword tools on the vidIQ and TubeBuddy pages.
