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.

Built by Patrick Stox

What this checker checks

  • For the exact page URL: Moz Page Authority. This is currently the only result specific to the submitted page.
  • For the registrable domain: Moz Domain Authority and Spam Score, Ahrefs Domain Rating, DataForSEO and Semrush authority and backlink metrics, and Majestic rank and flow metrics.
  • Also for the registrable domain: OpenPageRank score, global rank, and referring domains; plus your Common Crawl snapshot’s PageRank, PageRank position, harmonic-centrality value, harmonic rank, derived harmonic percentile, and number of aggregated hosts.

Why aren’t OpenPageRank and Common Crawl page-level? This OpenPageRank endpoint accepts domains, and the selected Common Crawl ranks dataset aggregates hosts into domain graph nodes. Their names contain “PageRank,” but these two rows do not evaluate the exact page URL you submit.

It does not crawl or audit the website. It does not check content, technical SEO, rankings, traffic, or Google’s internal PageRank. It looks up existing third-party and open-web metrics and keeps each provider’s result separate.

What you get without an API key

  • Ahrefs: Domain Rating.
  • Moz: Page Authority, Domain Authority, and Spam Score, subject to this site’s shared monthly allowance.
  • OpenPageRank: score, global rank, and referring domains, subject to this site’s shared monthly allowance.
  • Majestic Million: global and TLD rank plus referring subnet and IP counts from the hosted daily snapshot.

Common Crawl also needs no visitor key, but its production graph snapshot is currently disabled pending activation. When enabled, its card returns six graph fields: PageRank, PageRank position, harmonic-centrality value, harmonic rank, derived harmonic percentile, and aggregated hosts.

What currently needs your provider credentials

  • DataForSEO: rank, backlinks, referring domains, and backlink spam score.
  • Semrush: Authority Score, backlinks, and referring domains.
  • Majestic’s live API: Trust Flow and Citation Flow. This is separate from the free Majestic Million snapshot.

You can also provide Moz or OpenPageRank credentials as a fallback when the site’s shared allowance is unavailable or exhausted. Provider usage can consume your quota or incur charges under your account.

Use a full URL to make Moz Page Authority specific to that page. Domain-level providers use the registrable domain.

Use your own provider keys (optional)

Provide your own credentials for any provider to use your account and quota for this single request instead of this site's shared budget. Credentials are sent directly through this one request, are never stored, logged, or cached on this server, and are not saved when you reload the page.

Check multiple domains at once (optional)

Paste one domain or page URL per line, up to 10. Provider keys above, if filled in, apply to every domain in this batch. A provider whose shared quota is too small for the batch size shows its own "not included in this batch" message instead of running.

Checks run from our server; we fetch the URL you enter and don't keep the results. The normalized target is sent only to the named authority providers. Provider results may be cached for up to 30 days; API keys stay on the server. Optional provider keys you paste above are sent only with that one request and are never stored, logged, or cached. Anonymous run-level outcome counters may be used for aggregate research; URLs, domains, IPs, and identifiers are never included, and no statistic is released below 100 runs.

How to use it
 
     
  1. Enter a domain for website metrics, or a full URL when you also want page-specific Moz Page Authority.
    2.  
  2. Choose Check authority and review page and website sections separately.
    3.  
  3. Compare like with like: PA to PA, DA to DA, DR to DR, and each graph metric to the same source and release.
    4.  
  4. Investigate links, relevance, rankings, and traffic directly before making a decision; authority scores are summaries, not outcomes.
    5.

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.

Sobre a ferramenta
Consulte métricas de autoridade de página e domínio de vários provedores. Os resultados principais usam a cota compartilhada deste site e não exigem cadastro; resultados opcionais de provedores pagos exigem suas próprias credenciais.
Consulte métricas de autoridade de página e domínio baseadas em backlinks e no grafo da web, provenientes de Moz, Ahrefs, DataForSEO, Semrush, Majestic, OpenPageRank e Common Crawl.
Recursos
  • Escolha a verificação de autoridade e revise separadamente as seções de página e de site.
  • Compare métricas equivalentes: PA com PA, DA com DA, DR com DR e cada métrica de grafo com a mesma origem e versão.
  • Investigue links, relevância, classificações e tráfego diretamente antes de tomar uma decisão; pontuações de autoridade são resumos, não resultados garantidos.
  • Informe um domínio para métricas do site ou uma URL completa quando também quiser a Page Authority específica da página na Moz.
Como funciona
A Page Authority descreve a URL exata enviada à Moz; é o único resultado específico de página desta ferramenta. Domain Authority, Domain Rating, Authority Score da Semrush, classificações da Majestic, OpenPageRank e o grafo da Common Crawl descrevem o domínio registrável. O OpenPageRank aceita uma entrada de domínio, enquanto o conjunto de classificações da Common Crawl agrega hosts em nós do grafo de domínio. Um domínio forte ainda pode ter uma página nova fraca, e uma pontuação alta de provedor não garante classificações, tráfego, qualidade, relevância ou valor de link.
Limitações
  • Cada pontuação é modelada a partir de uma visão incompleta da web. Cotas de API, orçamentos, credenciais, cache, cobertura de rastreamento e tempo de atualização podem produzir valores ausentes ou diferentes. “Não encontrado” significa que não há dados disponíveis desse provedor, não autoridade zero. OpenPageRank e Common Crawl compartilham uma linhagem de dados da web aberta e não devem ser tratados como dois votos totalmente independentes. A ausência no Majestic Million significa apenas que o domínio está fora do milhão superior atual — não autoridade zero.
  • A ferramenta não rastreia nem audita o site. Ela não verifica conteúdo, SEO técnico, classificações, tráfego ou o PageRank interno do Google. Apenas consulta métricas existentes de terceiros e da web aberta e mantém o resultado de cada provedor separado.
Perguntas frequentes
Qual é a diferença entre autoridade de página e de site?
Métricas de página descrevem uma URL exata; métricas de domínio resumem um domínio registrável. Esta ferramenta envia a URL exata à Moz para obter Page Authority, enquanto Ahrefs DR, Moz DA, classificação da DataForSEO, Authority Score da Semrush, Majestic, OpenPageRank e métricas do grafo da Common Crawl permanecem no nível do domínio.
DA, PA, DR, classificação da DataForSEO, Authority Score da Semrush, Majestic e OpenPageRank são intercambiáveis?
Não. Moz, Ahrefs, DataForSEO, Semrush, Majestic, OpenPageRank e Common Crawl usam índices, fórmulas, cronogramas de atualização e escalas diferentes. Compare cada métrica apenas com a mesma métrica e origem.
Essas são pontuações de classificação do Google?
Não. Nenhuma dessas pontuações é o PageRank interno do Google ou um fator de classificação do Google. São medições de terceiros ou da web aberta que podem ajudar a comparar perfis de links.
Por que um provedor está indisponível?
Cada provedor é independente. Uma credencial de API ausente, cota ou orçamento esgotado, indisponibilidade temporária, instantâneo desativado da Common Crawl ou do Majestic Million, ou domínio ausente de um conjunto de dados afeta apenas esse provedor; os outros resultados ainda podem ser exibidos.
Posso usar minha própria conta da Moz, DataForSEO, Semrush, Majestic ou OpenPageRank?
Sim. Abra “Usar as chaves do seu provedor” abaixo da entrada e cole suas credenciais para qualquer provedor em que tenha uma conta. A solicitação usa sua conta e cota em vez do orçamento compartilhado deste site, é enviada diretamente pelo navegador para a solicitação e nunca é armazenada, registrada ou mantida em cache neste servidor.
