What does the Ahrefs’ Health Score show?
Correct: The proportion of internal URLs on your site that don’t have errors.
In the context of Ahrefs Site Audit, the Health Score is a specific technical SEO metric that represents the proportion of internal URLs on your site that don’t have errors, providing a high-level overview of your website's crawlability and indexability. It is calculated by taking the total number of internal URLs crawled and subtracting those that contain at least one "Error" (the most severe category of issues in Site Audit), then expressing that result as a percentage. While "Warnings" and "Notices" are identified during the crawl to help you further refine your site's performance, they do not negatively impact this specific score, allowing SEOs to focus on the most critical technical failures first. By monitoring this percentage over time, users can quickly gauge whether a recent site deployment or update has introduced significant technical debt or broken internal links that could hinder search engine bots.
