Health Score Calculation in Site Audit
Hello Ahrefs Team, I have carefully analyzed the Health Score calculation, examined the Site Audit settings, and identified inconsistencies that seem illogical and incorrect to me. Currently, the Health Score is determined as the ratio of the number of errors to the total number of crawled URLs. However, this includes not just actual website pages, but also irrelevant assets like images, JavaScript files, and other resources that Ahrefs happens to find during the crawl. Many of these are not part of the core website, and neither Google nor users ever interact with them. The issue: If I let Ahrefs crawl everything, including thousands of images and JS files, my Health Score remains high because the total number of URLs is large. If I optimize the crawl to include only real web pages (by using only URLs from the sitemap and setting crawl depth to 0), my Health Score artificially drops from 95% to 5%, even though the number of actual errors remains the same. This suggests that the score is influenced more by the volume of crawled URLs rather than the real health of the internal website pages. Why this is a problem: 95% of the total URLs crawled are "junk" files where errors are irrelevant (e.g., images don’t have broken links, and old JavaScript files don’t directly impact the core website). Health Score should reflect the quality of actual web pages, not be artificially improved by crawling thousands of unnecessary files. Conversely, removing irrelevant URLs should not punish the score. Suggested improvement: I believe that Health Score should be calculated based only on the total number of internal web pages, rather than all crawled URLs (including static files and assets). This would give a more accurate representation of the site’s real health and prevent the need to artificially inflate the number of crawled URLs just to maintain a high score. For reference, here are the latest audits where this issue can be observed: https://app.ahrefs.com/site-audit/4392596 I appreciate your time and consideration, and I hope this can lead to improvements in how Health Score is measured. Best regards, Martin
