Domain Authority Checker

What is Domain Authority Checker?

Domain Authority Checker is a bulk tool that checks the domain authority of thousands of websites in one run. Paste a list of domains or URLs and get, for each one, a 0-100 authority score, its global rank among about 135 million domains, the number of referring domains that link to it and how many subdomains it has. Click Start and download the table as Excel, CSV or JSON.

• ⚡ Speed: about 1,000 domains in 10 seconds
• 📋 Bulk: paste 10 or 100,000 domains; links, www. and subdomains are cleaned up and duplicates are checked once
• 🆓 Unknown domains are free: a domain with no link data is listed with found: false and not charged
• 🔓 No login, no API key, no subscription: pay only for the domains you check

What can Domain Authority Checker do?

• 🔗 Qualify link-building and guest-post prospects before you email them: set a minimum score and keep only strong sites.
• 🏷 Screen expired and auction domains before you buy: authority, referring domains and rank in one row.
• 📊 Benchmark a website against its competitors in a single run.
• 🧾 Enrich lead and partner lists with an authority column, then sort and filter in a spreadsheet.
• 📈 Track authority over time: run your own list again after a data update and compare the scores.

What data does the domain authority checker return?

Field	What it tells you
🌐 domain	The main domain that was scored (blog.example.com is scored as example.com)
🏆 domainAuthority	Authority score from 0 to 100: how well the domain is linked from the rest of the web
🎚 authorityLevel	very high (70+), high (50-69), medium (30-49), low (10-29), very low (under 10)
🥇 globalRank	Position among about 135 million domains by link authority; 1 is the strongest
🔗 referringDomains	How many other domains link to it
🧩 subdomains	How many hosts (www, blog, shop...) were seen on the domain
✅ found	false when the domain has no link data (free row)
📅 dataUpdated	Month of the link data the scores come from
✍️ input	The entry as you typed it, so you can match rows back to your list

How to check domain authority in bulk

1. Create a free Apify account (no credit card needed).
2. Open Domain Authority Checker and paste your domains or URLs into Domains or URLs, one per line.
3. Optional: set Minimum domain authority (for example 30) to keep only strong sites.
4. Click Start.
5. Open the Output tab and export the table to Excel, CSV, JSON or Google Sheets.

How much does it cost to check domain authority?

You pay per domain found, and domains with no link data are free.

Apify plan	Domains found per 1,000
Free	$1.00
Starter (Bronze)	$0.80
Scale (Silver)	$0.60
Business (Gold) and higher	$0.45

Platform usage is included in these prices, so you pay nothing else for the run. There is no start fee. Apify's free plan includes $5 of usage every month, enough for about 5,000 domains.

Example: a list of 10,000 domains where 9,000 have link data is billed as 9,000 domains: $9.00 on the Free plan, $4.05 on Business. The 1,000 unknown ones cost nothing. With a minimum score set, only the domains that pass it are saved and billed.

⬇️ Input

Setting	What it does
Domains or URLs	Domains or links, one per line: example.com, https://www.example.com/blog/post, shop.example.co.uk. Each is scored as its main domain.
Minimum domain authority	Optional. Save only domains scoring at least this (0-100). Domains below it and domains with no data are not saved and not charged.

Domain authority score explained

The score measures how strongly a domain is linked from the rest of the web, the same idea behind Moz Domain Authority and Ahrefs Domain Rating. It is our own score on the familiar 0-100 scale, not a copy of either one: every SEO tool computes authority from its own link data, so Moz, Ahrefs, Semrush and this tool all give a slightly different number for the same site. Use one tool's score consistently when you compare domains.

The scale is logarithmic, like the scores you know: going from 20 to 30 is easy, going from 80 to 90 is hard. About 1,700 domains in the world score 90 or more, about 19,000 score 80 or more, about 1.5 million score 50 or more, and a typical small website scores under 20.

Use it from code, Make, Zapier or n8n

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("automly/domain-authority-checker").call(run_input={
    "domains": ["apify.com", "dev.to", "gymshark.com"],
    "minDomainAuthority": 30,
})
for row in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(row["domain"], row["domainAuthority"], row["referringDomains"])

The actor works with Make, Zapier, n8n, webhooks and schedules, so you can score every new lead or prospect automatically.

Use with AI agents (MCP): connect Apify's MCP server to your AI assistant and ask, for example, "Check the domain authority of these 50 websites and list the ones above 40". The agent calls this actor with {"domains": [...], "minDomainAuthority": 40}.

❓ FAQ

Is this the same as Moz DA or Ahrefs DR?

No. It is our own authority score on the same 0-100 scale. It ranks domains in the same order of magnitude as those tools (very large sites score 90+, established brands 60-85, small sites under 30), but the exact numbers differ, as Moz and Ahrefs also differ from each other.

How fresh is the data?

The link data is refreshed regularly. Each row says which month its data comes from in dataUpdated.

Why does a domain show found: false?

The domain has no link data: it is new, unused, parked or nobody links to it yet. These rows are free.

Can I check subdomains or single pages?

You can paste them, and they are scored as their main domain: blog.example.com and https://example.com/page both return example.com. Sites on shared platforms (for example name.github.io or name.blogspot.com) are scored as the platform's domain.

How many domains can I check in one run?

As many as you like: 1,000 domains take about 10 seconds, and rows are saved as the run goes. Set a maximum cost on the run if you want a hard spending cap.

Do I need a Moz, Ahrefs or Semrush account?

No. You need only a free Apify account. There is no API key to buy and no subscription.

Something isn't working?

Open the Issues tab with your run link and the domains that look wrong, and we will look at it.
