Page Authority Finder

The Page Authority Finder is a free tool that measures five real, independently verifiable signals for any public page — domain age, indexability, HTTPS status, response speed, and server health — and combines them into a composite score out of 100, mapped to a letter grade from A+ to F. Rather than relying on a proprietary backlink index that requires expensive infrastructure to build, this score is calculated entirely from data anyone can check directly and for free.

It exists because not everyone has access to paid tools like Moz, Ahrefs, or Majestic, but there's still real value in a quick, standardized read on a page's underlying technical health. To be upfront: this is not the same metric as Moz's trademarked Domain Authority or Page Authority, which are built from a proprietary backlink index — it's SEOJuicer's own composite score, useful for tracking a page's technical foundation over time or comparing pages on the same domain, not as a direct substitute for backlink-based authority metrics.

When you submit a URL, the tool measures five signals directly and combines them into a weighted score out of 100: domain age from the domain's public RDAP registration record (up to 30 points), indexability by checking for a noindex directive and a declared sitemap (up to 25 points), whether the page loads over HTTPS (up to 15 points), live response speed (up to 15 points), and server health based on the actual HTTP status code returned (up to 15 points). The combined total is then mapped to a letter grade from A+ down to F.

Every signal here is measured live and independently for the specific URL you enter — this deliberately does not include backlink data, since a genuine backlink index requires crawling and indexing a large portion of the web, which is the expensive infrastructure behind paid tools like Moz and Ahrefs. Domain age and HTTPS status reflect the domain as a whole, while indexability, speed, and server health are checked specifically for the page you enter, so different pages on the same domain can score differently.

• Treat domain age as background context, not something to act on. It only changes by getting older, so a low score here isn't fixable this week — focus your effort on the signals that actually respond to changes.
• Fix indexability first if the score is low. A stray noindex tag or missing sitemap can be corrected in minutes and immediately improves this part of the score more than almost anything else.
• Remember speed compounds with everything else. A fast, reachable, HTTPS-secured, indexable site gives search engines every reason to crawl and trust it more, so speed fixes pay off across multiple signals at once.
• Use this score for internal tracking, not external comparison. Since it's SEOJuicer's own composite metric rather than a backlink-based one, compare a page against its own past scores rather than against Moz or Ahrefs numbers.
