Page and Website Authority Checker

How to read the results

Page Authority describes the exact URL submitted to Moz. It is the only exact-page result in this checker. Domain Authority, Domain Rating, Semrush Authority Score, Majestic's rankings, OpenPageRank, and the Common Crawl graph row describe the registrable domain. OpenPageRank accepts a domain input, while the selected Common Crawl ranks dataset aggregates hosts into domain graph nodes. A strong domain can still have a weak new page, and one high provider score cannot guarantee rankings, traffic, quality, relevance, or link value.

Data sources and freshness

Ahrefs, Moz, DataForSEO, Semrush, Majestic's live API, and OpenPageRank are queried through fixed provider endpoints and can reuse a cachedCaching stores a copy of a page or resource — in a browser, a CDN edge node, or a search crawler's own cache — so it can be served again without regenerating or re-downloading it. It isn't a direct ranking factor, but it feeds page speed and crawl efficiency. result for up to 30 days, matching how often these providers actually recrawl and republish their link graphs. The Common Crawl and Majestic Million results each come from an active, validated private snapshot and report that release's source date rather than a live per-request call. OpenPageRank is also derived from open-web graph data, so it is not an independent crawl from Common Crawl. Moz, OpenPageRank, Majestic Million, and the live Majestic API need this site owner to configure a provider credential (or dataset) and spending budget before they return live data; when a provider is not yet configured or disabled, its card says so instead of showing a fabricated number. DataForSEO and Semrush are pay-per-call rather than a fixed free tier, so they also need a configured owner budget, or a visitor-supplied key, before they run.

Bring your own provider key

DataForSEO, Semrush, and the live Majestic API currently require your own provider credentials because this site does not fund shared calls to those paid services. Moz and OpenPageRank normally use this site's shared allowance, but you can supply your own credentials as a fallback when that allowance is unavailable or exhausted. OpenPageRank keys come from a Keywords Everywhere account. Open “Use your own provider keys” above the input and paste only the credentials for the provider you want to run.

Those credentials are sent to this site's server for the request, used to call that provider on your behalf, and never stored, logged, or written to a cache. A result may be reused for up to six hours only in a separate cache namespace derived from a salted fingerprint of the same credentials; it is never placed in the site's shared-result cache. Clear the fields or reload the page when you're done. Usage can consume your provider quota or incur charges under your account. Ahrefs, Common Crawl, and the Majestic Million snapshot have no bring-your-own-key option here.

Limitations

Every score is modelled from an incomplete view of the web. API quotas, spend budgets, credentials, caching, crawl coverage, and update timing can produce missing or different values. “Not found” means absent from that provider’s available data, not zero authority. OpenPageRank and Common Crawl signals share an open-web data lineage and should not be treated as two fully independent votes. Majestic Million absence means only that a domain is outside the current top one million — not zero authority.
