Why we picked it Most of the traffic founders lose is not lost to competitors, it is lost to their own site quietly telling Google not to index it. This Ahrefs lesson walks through the technical mistakes that do exactly that (accidental noindex tags, blocked pages in robots.txt, broken canonicals, duplicate URLs) in plain language, with no jargon or paid tool required to follow along. Treat it as a starting point for a self-audit, not a full technical course.

- A single stray noindex tag or a robots.txt block can keep whole sections of your site out of Google, so check these first before blaming your content.
- Duplicate and near-duplicate URLs (trailing slashes, tracking parameters, http vs https) split your ranking signals, canonical tags tell Google which version counts.
- You do not need a paid tool to fix most of this, you need to know what to look for, which is what this rundown gives you.
