Domain authority for thousands of domains, from open web data

Check the authority of a whole prospect list in seconds, with no Moz, Ahrefs or Semrush account. Every domain gets a 0-100 score, its rank among 133 million domains, a top-% percentile, the number of subdomains seen on the web and a month-over-month trend. The scores are computed from the Common Crawl web graph, the open hyperlink map of the public web.

What it does

Domain Authority Checker, in short

A 0-100 authorityScore from the domain's harmonic-centrality and PageRank ranks, on a fixed log scale
Rank among 133 million domains, top-% percentile and an authority tier from very low to very high
Month-over-month rank change and trend: up, down, stable or new
Number of subdomains (hosts) of the domain seen in the crawl
Accepts domains, URLs and email addresses; each is reduced to its registrable domain
No website is visited and nothing is scraped: the web graph ships inside the actor

Pay per result. Failures are free.

$0.001domain scored · $1.00 per 1,000

No subscription, no monthly minimum. Apify platform compute is included in the price; Apify also adds a tiny start fee per run ($0.00005 per GB of run memory).

Example costs
You run	You pay
100 domains	$0.10
1,000 domains	$1.00
10,000 domains	$10.00
100,000 domains	$100.00

Worked example. You score a 5,000-blog outreach list and 1,200 of the blogs are not in the ranked web graph.3,800 scored × $0.001 = $3.80
1,200 unranked = $0.00

Not charged:

Domains outside the ranked top 12 million (returned with ranked: false: very few sites link to them)
Invalid inputs

A 10,000-domain list finishes in well under a minute, because no request is made per domain. You can set Maximum cost per run in the run options and the actor stops cleanly when it is reached.

FAQ

Questions

Is this the same as Moz DA or Ahrefs DR?

No. Those are proprietary. This score measures the same idea, how well linked a domain is across the web, from a public and reproducible source, so the ranking of domains against each other is what to rely on.

How fresh is the data?

Common Crawl publishes a new domain-level web graph about every month, each built from three months of crawling. The actor uses the latest one (dataRelease says which) and compares it with the previous one for the trend.

Why is my domain not ranked?

It is not in the top 12 million of 133 million domains, which means very few other sites link to it yet. That is a useful answer in itself, and it is free.

How are subdomains handled?

Scores are per registrable domain: blog.example.com is scored as example.com. hostsInCrawl tells you how many subdomains exist.

Does it return backlinks?

No. It returns authority and rank, not individual links.
