Domain Authority Checker
Check Domain Authority (DA), Page Authority (PA), and Spam Score for multiple domains at once. Accurate and free.
How to Use Domain Authority Checker
Follow these simple steps to get the best results.
List up to five domains
Enter one domain per line in the box; the tool keeps the first five, so paste a shortlist rather than a thousand rows.
Run the metrics lookup
Click Check to send the list to the server-side metrics endpoint and retrieve Domain Authority, Page Authority and Moz Spam Score for each host.
Read the three scores
See DA and PA on a one-to-hundred scale and Spam Score as a percentage; any metric the lookup did not return is shown as a dash, never estimated.
Frequently Asked Questions
Everything you need to know about Domain Authority Checker.
About the Domain Authority Checker Tool
Get an authority snapshot for a handful of domains in one pass. The ToolFlic Domain Authority Checker reads precomputed Moz-derived metrics - Domain Authority, Page Authority and Spam Score - from a server-side lookup and shows them for each domain you enter, up to five at a time. DA and PA are logged on a one-to-hundred scale and Spam Score as a percentage. Where the lookup returns nothing for a metric, the card shows a dash rather than a number, so an unanswered domain is obvious instead of silently estimated. It is a third-party estimate to benchmark against, not a Google score, and it does not list backlinks or referring domains.
Core Advantages
Compare a shortlist of sites quickly, spot a high Spam Score before you waste outreach effort, and watch how a domain reads over time. The bulk mode turns a five-minute set of single lookups into one request, and the honest dashes keep a failed metric from being mistaken for a low score.
Architecture & Security
The tool sends your domain list to a server-side metrics endpoint (da-proxy) that returns a Moz-derived da, pa and spam_score for each host; a null value is rendered as a dash and an error host is marked, never filled with a guess. These are third-party link-index estimates computed elsewhere, so they change as that index is recrawled - actual backlink and referring-domain detail lives in a link index or Search Console, not on this page.
Under the Hood: the Domain Authority Checker explained properly
No marketing filler — just the mechanics, the trade-offs and the real limits, explained clearly.
How it actually works
It reads precomputed Moz-derived metrics, meaning Domain Authority, Page Authority and Spam Score, from a server-side lookup and shows them for each host you enter. The list is trimmed to the first five domains, so it is a short comparison rather than a bulk crawl.
What that means for your results
DA and PA are logged on a one-to-hundred scale and Spam Score as a percentage, each taken from a third-party link index. When the lookup returns nothing for a metric the card shows a dash and the error host is marked, so an unanswered domain is obvious instead of being quietly filled with a low number.
Where it falls short — honestly
These are estimates computed elsewhere and they move only when that index is recrawled, and they are not a Google measure. The page shows no backlink list, no anchor text and no referring-domain count, because that detail lives in a link index. Numbers from different providers are not comparable, so track movement within one metric over time.
A real end-to-end workflow
Paste up to five domains one per line and run the lookup, then read Spam Score first to drop risky targets and DA second to gauge scale. Use it alongside Backlink Checker for the DNS and spam view of a single host and Domain Age Checker for registration history, keeping expectations to benchmarking rather than ranking prediction.
