Quick answer
A Moz DA checker shows Domain Authority, the 1 to 100 score Moz created to predict ranking ability from backlinks. This independent checker shows Moz's DA, PA and Spam Score when Moz's API returns them, and labels every other value Estimated.
What this Moz DA checker returns
Domain Authority and Page Authority are Moz metrics calculated from Moz’s link index. Spam Score is Moz’s percentage-based risk metric. When the Moz API returns these values, this tool preserves them and labels them Moz.
When original data is unavailable, the tool returns clearly labeled estimates from public signals. The full methodology is published rather than hidden.
When this combined workflow helps
- Bulk prospect lists: check up to 100 domains per batch with CSV input and export.
- Spam screening alongside authority: every check returns Spam Score next to DA, which is the pairing that decides whether a link is worth buying.
How to interpret the source labels
A Moz label means the value came from Moz and was not altered by local scoring. An Ahrefs label means Domain Rating came from Ahrefs. Estimated means the provider was unavailable and a documented fallback produced the value.
Compare like with like: Moz DA against Moz DA, and Ahrefs DR against Ahrefs DR. These are third-party comparison metrics, not Google ranking factors.
Checking DA in bulk without an account
Most link builders are not checking one domain. They are working a list of fifty or two hundred, and the bottleneck is how fast the list clears.
The bulk domain authority checker takes a pasted list or a CSV, returns DA, PA, DR and Spam Score for every row, and exports back to CSV so the results drop straight into whatever sheet you already use.
Why most checks show estimates
Moz data is shown only when Moz's API returns it for a check, and any Moz result is kept for 30 days. When it isn't available, DA and PA are estimated from the site's real Ahrefs Domain Rating and labeled Estimated, and Spam Score is estimated from official risk signals: the Spamhaus blocklist, registry age and HTTPS.
The result card spells this out under "Data source" for every check, so you never have to guess whether a number is Moz's. For a one-off check of Moz's own score, Moz's free Domain Analysis tool is the primary source.
Frequently asked questions
No. DAPA Checker is independent and is not affiliated with or endorsed by Moz. When the Moz API supplies a metric, the result is labeled Moz; otherwise it is labeled Estimated.
It can. Original Moz DA, PA and Spam Score are returned when Moz's API supplies them. We preserve those values and label them Moz. Fallback values are labeled Estimated and should not be expected to match Moz.
This tool combines available Moz metrics with Ahrefs Domain Rating, HTTPS, domain age and blocklist diagnostics in one workflow. Source labels show which values are original and which are estimates.
Up to 100 domains per batch through the bulk checker, with CSV upload and export, free and without an account.
No. Google has stated repeatedly that it does not use Domain Authority or any third-party authority metric in its ranking systems. DA is a prediction built by SEO tool vendors to estimate ranking ability, useful for comparison but not something Google itself consults.
