Is this a bulk Domain Authority checker?

No. This tool returns Ahrefs Domain Rating (DR), not Moz Domain Authority (DA). DR and DA are different metrics and should not be treated as interchangeable scores.

How many DR scores can I check at once?

Submit up to 10 non-empty lines with one public hostname per line. Duplicate hostnames are removed. The service uses request limits and can report individual provider failures; it is not an unlimited bulk API.

Why is one domain unavailable while the others have scores?

Each lookup can fail independently because of a provider refusal, timeout or batch deadline. Available measurements remain in the report. An unavailable result does not mean that Ahrefs measured a DR of zero.

Is this tool free and do I need an account?

It is free to use without an account. Domain checks have request limits to protect public services. Results can be downloaded from this page.

Where is my input processed?

Checks run on our server and contact public DNS, registry, website or Ahrefs services as needed. Results can be cached; inputs are not added to your URL or account. Do not submit private addresses or secrets.

Bulk Domain Rating checker

Check Ahrefs Domain Rating for up to 10 domains in one free report. Compare measured DR scores on the 0–100 scale, keep unavailable results separate from zero and export the readings with their measurement times as CSV. No account is required.

A report you can act on

Enter your domains to see measured values, sources and check times. Missing records, unsupported services and temporary failures are shown separately.

From input to output

How to use it

Paste up to 10 hostnames, one per line.
Duplicate hostnames share a reading; results are ordered by measured rating.
Export measurement times and statuses, keeping unavailable readings separate from zero.

Compare DR across a relevant group of websites

Enter one hostname per line, up to 10 non-empty lines. Duplicate hostnames share a reading. The report orders results by measured Domain Rating, with unavailable results kept separately so they cannot be mistaken for measured zeros.

A bulk DR check can support a review of related competitors or potential collaborations. Compare websites in context: Domain Rating measures backlink-profile strength, and does not measure content relevance, organic traffic or the value of a particular backlink.

Keep the source and time with every score

Every successful row identifies Ahrefs and the time its measurement was retrieved. Successful readings may be reused for one hour. Export the CSV to retain these details rather than copying scores without their measurement context.

Provider failures and rate limits remain visible per domain. If part of a batch cannot finish within the time limit, retry those domains separately. Neither a missing score nor a lower score establishes that a website is untrustworthy.

Measurement and usage limits

Successful readings may be reused for one hour. Results are backlink metrics, not traffic or rankings. Provider refusals and unavailable readings are shown per domain instead of being replaced with zero.
