Free Bulk Domain Authority Checker
The dachecker.io bulk DA PA checker is a free domain authority checker that returns three Moz metrics for multiple websites at once, every domain you paste in: Domain Authority (DA), Page Authority (PA) and Spam Score. You get them side by side in a table you can copy, export as a CSV file or save as report screenshots, which is usually what a link building shortlist or a client report needs. Whether you call it a DA PA checker, a PA DA checker or a dapa checker, it's the same check.
Fast, fresh and accurate. Every check returns the latest Moz data in seconds, and paid plans check up to 100 URLs at once, for DA here and for DR and TF in our other checkers.
Moz is one of three companies whose authority scores SEOs quote every day. When you want the Ahrefs view of the same domains, run them through our bulk Ahrefs DR checker as well, because the two indexes rarely agree to the point.
What Is Domain Authority (DA)?
Domain Authority is a score from 1 to 100, created by Moz, that predicts how likely a domain is to rank in Google search results compared with other domains. A higher DA means a stronger predicted ability to rank. Moz, the Seattle software company that started out as SEOmoz in 2004, calculates it from the links in its own web index, the same data you see in Moz Link Explorer.
Since the DA 2.0 update in 2019, the score comes out of a machine learning model. Moz feeds it signals such as the number of linking root domains, the total number of links and spam patterns, then trains it against real Google rankings so the score tracks which sites actually win. Our guide on how Moz calculates DA walks through the inputs one by one.
The scale is logarithmic. Going from DA 20 to 30 takes far fewer new linking domains than going from 70 to 80, which is why big sites barely move while young sites can jump after a handful of good links. DA is also relative: when Moz's index grows and strong sites gain links, your score can slip even though nothing changed on your side.
One thing DA is not: a Google ranking factor. Google's search team has said more than once that it doesn't use DA. After Google retired its public Toolbar PageRank score in 2016, third party scores like Moz DA, Ahrefs DR and Majestic TF became the shorthand SEOs use for link authority, and that's the right way to treat them. If you want the long answer, read does Domain Authority affect Google rankings.
Page Authority (PA) and How It Differs From DA
Page Authority uses the same 1 to 100 logarithmic scale and the same kind of model, but scores a single URL instead of a whole domain, which is why a DA and PA checker reports both, and why this page also works as a bulk PA checker. A site with DA 35 can have a blog post at PA 50 because that one article earned a lot of links on its own.
| Domain Authority (DA) | Page Authority (PA) | |
|---|---|---|
| Scores | A whole domain | One URL |
| Built from | Links to every page on the domain | Links to that page, plus the domain's strength |
| Best for | Comparing sites against each other | Picking the exact page a link sits on |
| Made by | Moz | Moz |
In practice you want both numbers. A guest post on a DA 60 site still lands on a brand new page with almost no PA, so the link's value comes mostly from the domain, while a link added to an existing article that already has PA 40 inherits that page's strength. This checker reports the PA of each domain's homepage; for page level work, our article on Page Authority vs Domain Authority covers how to read the two together.
What Is Moz Spam Score?
Spam Score, often shortened to SS, is the percentage of sites with features similar to the one you're checking that Moz found to be penalized or banned by Google. It doesn't say a site is spam. It says sites that look like this one often turned out to be. Moz groups the result into three bands:
- Low, 1% to 30%: nothing unusual in the link profile.
- Medium, 31% to 60%: worth a closer look before you build a link there.
- High, 61% to 100%: check the site by hand; plenty of these are link farms or dropped domains rebuilt for selling links.
Because every check returns it next to DA and PA, this DA PA spam checker doubles as a bulk spam score checker. A high DA with a high Spam Score is the classic sign of inflated authority, so read the two together rather than trusting DA alone. More detail is in what is Moz Spam Score.
DA vs DR vs TF: Which Authority Metric Should You Use?
Moz, Ahrefs and Majestic each crawl the web with their own bots and score sites with their own formulas, so the same domain can be DA 45, DR 60 and TF 20 on the same day. None of them is the true number; they measure different things.
| Metric | Company | What it measures | Scale |
|---|---|---|---|
| Domain Authority (DA) | Moz | How likely a whole domain is to rank, predicted from its link profile | 1 to 100, logarithmic |
| Page Authority (PA) | Moz | The same prediction for one URL | 1 to 100, logarithmic |
| Spam Score | Moz | Share of sites with similar features that Google penalized or banned | 1% to 100% |
| Domain Rating (DR) | Ahrefs | Strength of a site’s backlink profile against every other site Ahrefs has crawled | 0 to 100, logarithmic |
| Trust Flow (TF) | Majestic | Link quality, based on how close a site sits to a hand-picked set of trusted seed sites | 0 to 100 |
| Citation Flow (CF) | Majestic | Link volume and influence, regardless of quality | 0 to 100 |
Our rule of thumb: use DA or DR to size a site up, and use Trust Flow to catch the ones whose authority comes from junk. A big gap between Citation Flow and Trust Flow, say CF 40 with TF 8, usually means lots of low quality links. You can pull TF and CF for a list in our TF checker.
Semrush adds a fourth number, Authority Score, on a 0 to 100 scale that blends its backlink data with organic traffic. Our Semrush Authority Score checker returns it for a whole list.

What Is a Good Domain Authority Score?
A good DA is one that beats the sites ranking for your keywords, not a fixed number. Check the domains on page one for your main search term and compare yourself with their average. These ranges are a rough guide to what's normal by type of site:
- Local businesses: DA 20 to 30. You're up against other local firms, not national brands.
- Small online stores: DA 30 to 40 is solid.
- Niche blogs: DA 20 to 35 when new, 40 to 55 once established.
- News publishers: DA 60 to 80, since citations bring links in daily.
- Large brands: DA 70 to 90 after years of PR and natural links.
- The very top: DA 90 and above, the territory of Wikipedia, Google and major universities.
So a local plumber at DA 25 whose competitors sit at 15 to 20 is ahead, while a marketing agency at DA 25 facing competitors at 60 has work to do. We go deeper in what is a good Domain Authority score.
How SEOs Use a Domain Authority Checker
Checking domains one at a time in a browser tab is fine for two sites and miserable for two hundred. These are the jobs a bulk DA PA checker tool speeds up most:
- Vetting guest post sites: used as a guest post DA PA checker, it takes a whole outreach list at once: drop anything below your DA floor or above your Spam Score ceiling, then judge the rest on relevance and real traffic.
- Competitor gap analysis: compare your DA with the sites ranking above you and with the sites linking to them, which our free backlink checker lists for any domain.
- Expired domain due diligence: a dropped domain with good DA and a low Spam Score is worth a closer look; a high Spam Score usually means a past life selling links.
- Client reporting: agencies track DA, PA and Spam Score for every client domain and hand over the screenshots as monthly proof of progress.
- Tracking your own site: check once a month. DA moves slowly, so daily checks only show noise.
How to Increase Your Domain Authority
DA goes up when more strong, relevant domains link to you, and almost everything else is a way of earning those links. The full playbook is in how to increase Domain Authority; the short version:
- Earn links from new referring domains. Ten links from ten relevant sites beat fifty from one, because linking root domains carry most of the weight. Editorial mentions, digital PR and guest posts on real sites all count.
- Publish things people cite. Original data, free tools, calculators and genuinely complete guides attract links without outreach.
- Fix broken pages. Redirect old URLs that still have backlinks with a 301 so their link equity isn't wasted on a 404.
- Link your own pages well. Internal links spread authority to the pages you want to rank and help search engines understand your structure. They raise PA more than DA.
- Leave random spam links alone. Every site picks up some, and Google already ignores most of them. Google says most sites never need its Disavow Tool and that misusing it can hurt; save it for a big batch of unnatural links you built, or a manual action in Google Search Console.
- Give it time. DA only moves when Moz recalculates it from its link index. Expect three to six months before good link building shows up in the score.
What not to do: buy links from link farms or private blog networks (PBNs), spam blog comments, swap links with unrelated sites or run automated link tools. They can lift a score for a while, and they're exactly what Spam Score and Google's spam systems are built to catch.
If you'd rather have it done for you, our team runs white hat DA growth campaigns with manual outreach on relevant sites.

Frequently Asked Questions (FAQ)
Using the DA PA Checker
How do I check DA PA for many websites at once?
Paste the domains or URLs into the box at the top of this page, one per line, and click Check Authority. It works as a DA PA checker in bulk, from one site to a whole list. You get Moz Domain Authority, Page Authority and Spam Score for each one, ready to copy, export as CSV or download as report screenshots.
Is it a free DA checker, and do I need an account?
Yes, it is free, and no account is needed. You can start checking straight away. Signing up for a free account triples the daily allowance, and paid plans raise how many domains you can paste per run.
Can I check a subdomain or a specific page?
Every input is checked as its domain, so a full URL returns the domain's DA and the PA of its homepage. DA is a domain wide metric; subdomains usually share the root domain's authority unless Moz scores them separately.
Does this DA PA checker use Moz data?
Yes. The numbers come from Moz's link index, the same data Moz shows in Link Explorer. Mozscape was the old name of that index and its API; Moz now serves the same link data through its Links API. Our providers query it for each domain you check, so it works as a bulk Moz DA checker without a Moz subscription.
How fresh is the DA data?
Fresh and up to date. Every check returns the latest Domain Authority, Page Authority and Spam Score from Moz's index, not scores saved weeks or months ago like some checkers show.
How many URLs can I check at once?
Without an account, 3 domains per run and 3 a day; a free account allows 9 a day. Paid plans check 20 URLs per run on Basic and 100 per run on Plus and above, with monthly allowances of 2,000 to 100,000 checks, so a list of 500 or 1,000 URLs goes through in a few runs.
What does SS mean in a DA PA SS checker?
SS is short for Moz Spam Score. Every check here returns DA, PA and SS together, so a DA PA SS checker and this page are the same thing.
Is there a DA PA checker extension?
We don't offer a browser extension. This page does the same job in any browser, on a phone or a desktop, and checks a whole list at once, which a toolbar extension can't. Bookmark it to keep it one click away.
How fast are the results?
A free batch usually comes back in a few seconds. Bigger paid batches are checked in chunks, and a progress counter shows how many domains are done while you wait.
Understanding DA Scores
Is Domain Authority a Google ranking factor?
No. Google does not use DA, PA or any third party score in its rankings. DA is Moz's prediction of ranking ability based on links, useful for comparing sites but not something Google reads.
Why did my DA drop when I didn't lose any links?
DA is relative. When Moz refreshes its index and other sites gain links faster than yours, your score can fall even though your own link profile didn't change.
How often is DA updated?
Moz recalculates Domain Authority as its link index is refreshed, so a score can move from one check to the next. Bigger jumps usually follow a Moz index update, and Moz does not publish a fixed schedule.
Why do DA, DR and TF give different numbers for the same site?
They come from three separate link indexes and answer three different questions: DA predicts ranking ability, DR rates backlink profile strength and Trust Flow rates link quality. A gap between them is normal, not an error.
Does a high DA guarantee traffic?
No. DA predicts ranking potential from links, but traffic depends on which keywords a site ranks for and how often people search them. Check organic traffic separately before paying for a link.
Improving and Protecting DA
How long does it take to improve DA?
Months, not weeks. New sites can gain points quickly, but every extra point costs more links than the last because the scale is logarithmic, so established sites move slowest.
Do internal links help DA?
They help Page Authority and how authority flows around your site, but DA is calculated mainly from external links pointing to your domain.
Does site speed affect DA?
Not directly. Speed matters for Google and for visitors, but DA is built from link data. A faster, better site can earn more links over time, which is what moves DA.
Do 301 redirects pass DA?
Mostly, yes. A 301 redirect passes most of the link equity of the old URL to the new one, so links to a moved page keep counting toward your authority.
