Page Authority Finder

No, and we want to be upfront about that: Domain Authority and Page Authority are trademarked metrics owned by Moz, calculated from their own proprietary backlink index, and only available through their paid API with no free tier. This tool is SEOJuicer's own composite score, built entirely from signals we can measure directly and for free — it estimates a different, narrower slice of authority and shouldn't be treated as a substitute for Moz's numbers.

Five measurable signals, each weighted differently: domain age (up to 30 points, from public registration records), indexability (up to 25 points, checking for a noindex tag and a declared sitemap), HTTPS (up to 15 points), response speed (up to 15 points), and server health based on the HTTP status code (up to 15 points). They're added together for a score out of 100, then mapped to a letter grade from A+ to F.

Real backlink data — the number and quality of other sites linking to a page — requires crawling and indexing a huge portion of the web, which is exactly what makes services like Moz, Ahrefs, and Majestic paid products with expensive infrastructure behind them. We don't have access to that data for free, so rather than fabricate a number, we built this score entirely from signals that can be verified live and independently for any domain.

Yes — indexability, response speed, and server health are all checked for the specific URL you enter, not the domain as a whole, so a slow or noindexed page can score lower than the domain's homepage even though domain age and HTTPS status stay the same across the whole site. Check the page you actually care about, not just the root domain.

Domain age barely moves and HTTPS status rarely changes, so there's little value in checking daily — but indexability, speed, and server health can shift after a deploy, a robots.txt edit, or a hosting change, so it's worth re-checking after any change that could affect them. Treat it as a quick health check rather than a metric to track hour by hour.
