How to use domainrating.org

Check a domain

Type a domain into the search box on the homepage, or go straight to /domain/example.com. The page shows the domain’s OAR, its position in the web graph and its trend across Common Crawl releases. A domain with too little presence in the graph gets no score at all rather than a guess. Domains you open are listed under “Recently checked” on the homepage; that list lives only in your browser and Clear removes it.

How the score is calculated

OAR is derived only from Common Crawl’s published host and domain graphs, with a published formula, so anyone can reproduce it. It is not comparable to Ahrefs DR or Moz DA, and nobody can pay to change it. The methodology page has the formula, the data page the current release and ingest status, and the changelog every algorithm change.

Compare domains and browse top lists

Compare puts two or three domains side by side: scores, graph positions and trends. The comparison lives in the address, so you can bookmark or share it. Paste four to ten domains into the bulk check instead and they come back as one table, ranked by OAR, with each domain’s change since the previous crawl release. Top domains lists the highest-rated domains, globally and per top-level domain.

Track domains on your dashboard

With a free account, press Track this domain on any domain page. Your dashboard lists every tracked domain with its current score and how it changed since you started tracking it, and you can add a private note to each one. You can track up to 200 domains, compare tracked domains in one step, and download the whole list as a CSV file from the dashboard. The file also has each domain’s score in the latest crawl releases, one column per release, so you can chart the trend in a spreadsheet. Nobody can see who tracks a domain.

Turn on score-change emails on the dashboard (it needs a verified email address) and after each new crawl release you get one email listing the tracked domains whose score moved, with nothing sent when none did. Every email has a link to stop them, and you can turn them off on the dashboard at any time.

Verify that you own a domain

Owners can earn a public “Verified owner” checkmark from their domain’s page. Any one of three proofs is enough: a DNS TXT record at the domain apex, an HTML meta tag in your homepage’s <head>, or the rating badge embedded on your homepage. Proofs are re-checked about every 30 days; if a proof disappears you get a grace period to restore it before the checkmark is removed, and you can remove the verification yourself at any time. What our fetcher does during these checks is described on the bot page.

Use the API

GET /api/v1/domains/{domain} returns a domain’s score as JSON. Anonymous requests are limited per IP (120 an hour on cache misses). With an API key from your account page, the free tier allows 1,000 requests an hour; the paid tier allows 10,000 and adds enrichment data and top lists. The API documentation covers every endpoint, and /openapi.json is the machine-readable spec.

Manage your account

The account page is where you set a display name, change your password, see how you sign in (email and password, or Google), resend the email verification link, create and revoke API keys, and delete your account. Deleting it removes your account data as described in the privacy policy.

Paid features

Checking, comparing and tracking domains is free. Two things cost money: the paid API tier and sponsorship placements, which are clearly labelled and never affect a score. There is no self-serve checkout yet: the paid API tier is granted by hand once payment has been arranged, so contact us to upgrade. The terms of service apply to both.

Most questions are answered in the FAQ. For anything else, or to report a wrong score or a broken page, use the contact page or report an issue.
