What Is a DA Checker?
A DA checker tells you how much authority a website has built through its backlinks. Type in a domain and it returns the score an SEO index gives it, so you can judge a site in seconds instead of guessing from its design or a seller's traffic claims. Most tools stop at Moz Domain Authority. dachecker.io checks DA, Ahrefs Domain Rating and Majestic Trust Flow together, because one number on its own is easy to fake and easy to misread.
The numbers come from the same link indexes the big SEO suites use. When you run a check, our data providers query Moz, Ahrefs and Majestic for that domain and send the scores back, usually within a few seconds. A result can come from a cache up to 12 hours old, and that matters less than it sounds: these scores only move when each company refreshes its index, so a site's DA rarely changes from one day to the next. If you only need Moz metrics for a list, our domain authority checker adds Page Authority and Spam Score for every site.
To check website authority for free, paste a domain into the box at the top of this page and press check. Your first checks each day need no account. For a list of sites the bulk tools are faster: up to 3 domains per run for free, or up to 100 on a paid plan, with results you can export as a CSV file or a set of report screenshots.
What the DA, DR and TF Checker Shows
DA, DR and TF are the three authority scores SEOs quote most. Each comes from a different company with its own crawler, so together they give you three independent opinions on the same site.
Domain Authority
A machine learning prediction of how likely a domain is to rank in Google, built from the links in Moz’s web index, the same data Moz Link Explorer shows. It weighs linking root domains most heavily.
Check DA and PA in bulkDomain Rating
The strength of a site’s backlink profile compared with every other site in the Ahrefs index. It counts unique referring domains with followed links, weighted by their own DR.
Check DR in bulkTrust Flow
How close a site sits to a hand-picked set of trusted seed sites in Majestic’s link graph. Its partner, Citation Flow (CF), measures link volume without judging quality.
Check TF and CF in bulkNone of the three is a Google ranking factor. Google retired its public Toolbar PageRank in 2016, and these scores became the shorthand SEOs use for link authority since. Our guide to the DA, DR and TF framework goes deeper.
Why Check DA, DR and TF Together
One score can be gamed or out of date. When three separate indexes agree, the authority is real; when they disagree, the gap tells you what to look at. These are the patterns we see most when vetting sites:
| What you see | What it usually means |
|---|---|
| DA, DR and TF all high | Three independent link indexes agree the site is strong. This is the profile you want for a link or a domain purchase. |
| DA and DR high, TF low | Plenty of links, few trusted ones. Typical of sites that sell links or sit in a private blog network; check Spam Score before paying. |
| DR high, DA much lower | Often new links that Ahrefs has found and Moz has not crawled yet. Recheck in a few weeks before deciding. |
| CF far above TF | Link volume without trust, for example CF 40 with TF 8. Usually comment, forum or directory spam. |
| All three low | A new or weak site. Fine for a relevant, niche link, but it passes little authority today. |
Use the one-click check when a single site is on the table: a guest post offer, a link seller's domain, an expired domain at auction or a quick look at a competitor. When you have a list, run it through the bulk tools below, then come back here for the sites that need a closer look. For the difference between the two most quoted scores, read DA vs DR.
What Is a Good DA, DR and TF Score?
There's no universal pass mark, and anyone who quotes one without asking about your niche is guessing. A DA 25 site can be the strongest blog in a small local market, while DA 50 is ordinary for a national news site. Compare a site with the others ranking for the same topic, not with the whole web. Still, after vetting thousands of link prospects, these are the rough bands I start from:
| Site strength | Moz DA or Ahrefs DR | Majestic Trust Flow |
|---|---|---|
| Weak or new | 0 to 20 | 0 to 10 |
| Average | 20 to 40 | 10 to 20 |
| Strong | 40 to 60 | 20 to 35 |
| Authority site | 60 and up | 35 and up |
Two checks matter more than the bands. First, the gap between scores: DR 50 with TF 5 means lots of links and almost no trusted ones, which is exactly how a link farm looks. Second, the Spam Score. Moz flags sites that share features with penalised ones, and anything above 30% deserves a manual look before you pay for a link. Want to raise your own numbers rather than just measure them? That's the job of our link building services.

Frequently Asked Questions
What is the difference between DA, DR and TF?
DA is Moz’s prediction of a domain’s ability to rank, DR is Ahrefs’ score for the strength of a backlink profile, and TF is Majestic’s measure of link quality based on closeness to trusted seed sites. Each comes from a different company’s own crawler and formula.
Why do DA, DR and TF show different numbers for the same site?
The three companies crawl the web separately and score different things, so a site can be DA 45, DR 60 and TF 20 on the same day. None of them is the true number. A gap between them is information, not an error.
Are DA, DR or TF Google ranking factors?
No. Google does not use any third party authority score. They are useful because they summarise link data that Google also cares about, but Google never reads them.
How many domains can I check at once?
The DA, DR and TF checker on this page takes one domain per check: 2 checks a day without an account, 5 when signed in, and 200 to 7,500 a month on paid plans. For lists, use the bulk checkers: up to 3 domains per run for free and up to 100 on paid plans.
How accurate is the Domain Authority data?
The scores come from Moz’s own link index through our data providers, the same data Moz shows in Link Explorer. A result can be served from a cache up to 12 hours old, which rarely matters: DA only changes when Moz refreshes its index.
Are the other SEO tools free?
Yes. The bulk URL opener, duplicate backlinks finder, duplicate checker, column combiner, data cleaner, bulk hyperlink generator, Google index checker and on page audit are free with no sign up, and most of them run entirely in your browser.
