Backlink indexing metrics in SEO track which links search engines have actually found, crawled, and stored in their database. You might see impressive numbers from an SEO tool, but if those backlinks aren't indexed, they won't pass authority to your site. This metric shows the gap between all existing backlinks and the ones Google actually uses, helping you decide where to focus link-building cleanup or new outreach.
