Page and Website Authority Checker
Look up page and domain authority metrics from multiple providers. Core results use this site’s shared allowance and require no signup; optional paid-provider results require your own credentials.
Sample report
Illustrative structure—no provider score is invented
How to use it
- Enter a domain for website metrics, or a full URL when you also want page-specific Moz Page Authority.
- Choose Check authority and review page and website sections separately.
- Compare like with like: PA to PA, DA to DA, DR to DR, and each graph metric to the same source and release.
- Investigate links, relevance, rankings, and traffic directly before making a decision; authority scores are summaries, not outcomes.

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.
Frequently asked questions
What is the difference between page and website authority?
Page-level metrics describe one exact URL; domain-level metrics summarize a registrable domain. This checker sends the exact URL to Moz for Page Authority while Ahrefs DR, Moz DA, DataForSEO rank, Semrush Authority Score, Majestic, OpenPageRank, and Common Crawl graph metrics remain domain-level.
Which authority checks are free without my own API key?
Ahrefs Domain Rating, Moz Page Authority and Domain Authority, OpenPageRank, and Majestic Million use this site’s shared allowance or hosted dataset and do not require a visitor key while available. Common Crawl also requires no visitor key, but its production snapshot is currently disabled pending activation. DataForSEO, Semrush, and live Majestic Trust Flow/Citation Flow currently require your own provider credentials.
Are DA, PA, DR, DataForSEO rank, Semrush Authority Score, Majestic, and OpenPageRank interchangeable?
No. Moz, Ahrefs, DataForSEO, Semrush, Majestic, OpenPageRank, and Common Crawl use different indexes, formulas, update schedules, and scales. Compare each metric only with the same metric and source.
Are these Google ranking scores?
No. None of these scores is Google’s internal PageRank or a Google ranking factor. They are third-party or open-web measurements that can help compare link profiles.
Why is one provider unavailable?
Each provider is independent. A missing API credential, provider quota or spend budget, temporary outage, disabled Common Crawl or Majestic Million snapshot, or a domain absent from a dataset affects only that provider; the checker still shows the other results.
Can I use my own Moz, DataForSEO, Semrush, Majestic, or OpenPageRank account?
Yes. Open “Use your own provider keys” below the input and paste your own credentials for any provider you have an account with. That request runs against your account and quota instead of this site’s shared budget, is sent directly through that one request, and is never stored, logged, or cached on this server.

Informazioni sullo strumento
Cerca metriche di autorevolezza della pagina e del dominio basate su backlink e grafi web da Moz, Ahrefs, DataForSEO, Semrush, Majestic, OpenPageRank e Common Crawl.
Funzionalità
- Metriche separate per pagina e dominio con provider e data della risposta.
- Uso facoltativo delle tue credenziali, mai memorizzate o registrate dal server.
- Risultati indipendenti con quote, assenza nei dataset e indisponibilità dichiarate.
- Report leggibile che conserva l’origine di ogni metrica.
Come funziona
Il checker invia richieste delimitate ai provider disponibili e conserva ogni risultato separato. Le metriche Common Crawl e OpenPageRank condividono una discendenza open web e non sono due voti pienamente indipendenti.
Limitazioni
- Il tool non esegue crawl o audit del sito e non misura contenuti, ranking, traffico o PageRank interno di Google.
- Quote, costi, credenziali, snapshot e copertura dei provider possono produrre valori mancanti o diversi; un dominio non trovato non equivale ad autorità zero.
Domande frequenti
Quali controlli sono gratuiti senza una mia chiave API?
Dipende dal provider e dal budget condiviso corrente. Il pannello mostra quali risultati sono disponibili e indica onestamente quote o credenziali mancanti.
Il tool esegue il crawl del mio sito?
No. Recupera metriche di terze parti e segnali open web; non analizza pagine, contenuti o traffico.
Un valore mancante significa autorità zero?
No. Significa che il provider non ha restituito un valore disponibile per quella richiesta o quel dominio.
Posso usare le mie credenziali?
Sì. Inseriscile nel pannello dedicato; vengono inviate direttamente alla richiesta, senza essere salvate o registrate sul server.
