Bulk Domain Metrics Checker

Most SEO metrics live behind paywalls — Ahrefs, Moz, and the rest all want a subscription before they'll show you a single number, and they check one website at a time. This free bulk domain metrics checker flips that around: paste a list of websites and get Ahrefs Domain Rating (DR), Moz Domain Authority (DA), backlinks, referring domains, spam score and Open PageRank for every one of them, side by side, in seconds.

There's nothing to install and no account to create. Every score comes straight from the official public data behind Ahrefs, Moz and Open PageRank — so the numbers match what you'd pay for, you're just checking them in bulk, for free, with a single click.

What metrics does this bulk checker show?

For each domain you enter, the tool returns a full authority snapshot in one row:

• DR (Domain Rating) — Ahrefs' 0–100 score of a website's backlink profile strength. The go-to number for judging how hard a site is to outrank.
• DA (Domain Authority) — Moz's 0–100 predicted ranking strength, calculated from its own link index.
• Backlinks — the total number of external inbound links (pages) pointing at the domain.
• Referring domains — how many unique websites link to it. Often more telling than raw backlink count, because 1,000 links from one site count far less than links from 1,000 different sites.
• Spam Score — Moz's 0–100 estimate of how risky a domain's link profile looks. Lower is better.
• Open PageRank (PR) — a free 0–10 PageRank-style authority score, handy as a cross-check against DR and DA.
• DA Trend — whether the domain's authority is rising, falling or flat over recent months.

Large numbers like backlinks and referring domains are shown in a compact form (1.2K, 3.4M, 1.5B) — hover any figure to see the exact value. You can sort by any column and export the whole table to CSV, Excel or PDF, or copy it straight to your clipboard.

What is Ahrefs Domain Rating (DR)?

Domain Rating (DR) is Ahrefs' 0–100 measure of how strong a website's backlink profile is. It weighs how many unique domains link to a site and how authoritative those linking sites are, then compresses the result onto a logarithmic scale — so moving from DR 20 to DR 30 is far easier than moving from DR 70 to DR 80. DR is the fastest single-number answer to "how hard will this site be to outrank?"

What is Moz Domain Authority (DA)?

Domain Authority (DA) is Moz's 0–100 score that predicts how well a website will rank in search results. Like DR, it's built from backlink data on a logarithmic scale, but it uses Moz's own link index — so DR and DA rarely match exactly. Checking both gives you a more balanced read on a domain's real authority than trusting either one alone.

DR vs DA vs Open PageRank — which should you trust?

They measure the same underlying thing — backlink strength — from three different indexes, so treat them as three opinions rather than one truth:

• Ahrefs DR draws on one of the largest live backlink crawls, which is why it's the industry default.
• Moz DA is the longest-established alternative and still widely quoted in outreach.
• Open PageRank is free and open, a useful sanity check when DR and DA disagree.

When all three point the same way, you can be confident. When they diverge, the backlinks and referring-domains columns tell you why — a site with high DR but few referring domains may be leaning on a handful of powerful links.

How to check domain metrics in bulk

1. Add your domains. Type or paste them into the box above — one per line, or separated by commas. Full URLs work too; we reduce them to the root domain automatically.
2. Click "Check Domain Rating". Every domain is looked up in parallel, so even long lists finish in seconds.
3. Read the table. DR, DA, PR, backlinks, referring domains, spam score and trend appear together. Sort by any column to rank your list.
4. Export or copy. Download to CSV, Excel or PDF — abbreviated numbers export as full values — to drop straight into a spreadsheet or outreach sheet.

Why check these metrics in bulk?

Checking one domain at a time is fine for a single site. It falls apart the moment you have a list. A bulk checker saves hours whenever you need to:

• Vet link-building and guest-post prospects. Screen a list of outreach targets and instantly spot which carry real authority — and which have a high spam score you should avoid.
• Size up the competition. Drop in every domain ranking on a search results page and see the DR, DA and backlink landscape you're up against for a keyword.
• Evaluate domains before you buy. Compare expired or auction domains on DR, DA, referring domains and spam score at a glance instead of pasting each into a separate tool.
• Audit your own backlink profile. Check the domains linking to you to understand the quality — and the risk — of your existing links.
• Clean up prospect lists. Filter a big spreadsheet down to only the domains above the DR, DA or referring-domain threshold that matters to you.

What is a good DR or DA score?

There's no universal "good" — a DR 35 site can dominate a low-competition niche while a DR 60 site struggles in a brutal one. Always compare a domain against the sites you actually compete with. As a rough frame (the same bands apply to both DR and DA):

• 0–20 — new or very small sites with little link equity yet.
• 21–40 — established sites with a real, growing backlink profile.
• 41–60 — strong sites that compete comfortably in most mid-difficulty niches.
• 61–80 — authorities: large publishers, established brands and institutions.
• 81–100 — the web's giants, such as Google, YouTube and Wikipedia.

Where does the data come from?

DR is pulled from Ahrefs' official public Domain Rating data — the same metric behind Ahrefs' own free checker. DA, backlinks, referring domains and spam score come from Moz's link index, and PR from the Open PageRank project. Nothing here is an estimate or a made-up approximation; these are the real published metrics, simply gathered together and shown in one table.

Frequently asked questions

Is this bulk domain metrics checker really free?

Yes. You can check DR, DA, backlinks, referring domains, spam score and PageRank with no sign-up, no credit card and no Ahrefs or Moz subscription. It's a genuinely free tool.

How many domains can I check at once?

You can check up to 500 domains in a single run. Duplicate entries are merged automatically, so your list is de-duplicated before it's processed.

Do I need an Ahrefs or Moz account or API key?

No. You don't need an account, an API key or any login for either service. Just paste your domains and check.

Why do DR and DA show different numbers for the same site?

Because they're calculated by different companies from different link indexes. Ahrefs DR and Moz DA both score backlink strength 0–100 on a logarithmic scale, but they're not interchangeable. That's exactly why this tool shows both — together they give a fuller picture.

What is a good backlink-to-referring-domain ratio?

There's no fixed rule, but a healthy profile usually has links coming from many different referring domains rather than thousands of links from just a few. A site with millions of backlinks but only a handful of referring domains is often weaker than the raw backlink count suggests.

What does the spam score tell me?

Moz's Spam Score (0–100) estimates how risky a domain's link profile looks compared with sites that have been penalised. A low score is reassuring; a high score is a flag to investigate before you build or accept links from that domain. A dash means Moz returned no spam score for it.

Why does a domain show 0 or a dash?

A DR or DA of 0 usually means the domain has effectively no backlinks — often a brand-new or parked site. A dash (—) means that particular metric wasn't returned, typically because the domain doesn't resolve or hasn't been crawled. Re-running the check occasionally clears up temporary lookup failures.

How accurate and up to date are the scores?

The numbers reflect the current published metrics from each source and match what you'd see in the paid tools' own free checkers. These scores change slowly — usually by a point or two as a site earns or loses links — so the figures stay reliable day to day.
