Moz Domain Authority Checker

Moz Domain Authority Checker gets Moz metrics for thousands of domains at once, without a Moz account or subscription. For each domain you get:

• Domain Authority (DA), Moz's score of how likely a site is to rank;
• linking root domains, the number of distinct domains that link to the site;
• ranking keywords and spam score;
• the top pages by Page Authority and the top linking domains with their DA;
• 60 days of discovered and lost linking domains, day by day.

US$ 7.00 per 1,000 domains, residential proxy included. No monthly fee, no start fee. Invalid and failed domains are free.

At a glance

• Price per 1,000 domains: US$ 7.00, no run start fee
• Moz account: Not needed
• Proxy: Residential, included in the price (Moz blocks datacenter IPs)
• Per domain: DA, linking root domains, ranking keywords, spam score, top pages, top linking domains, 60-day link history
• Speed: About 100 domains in 2 to 3 minutes
• Error rows: Free, with an errorCode

In the same run, 100 well-known domains came back in 142 seconds, for example github.com DA 97, notion.so DA 86 and moz.com DA 91.

What you can do with it

• Link building and outreach: score thousands of prospect sites by DA and spam score before you contact them.
• Domain buying and expired domains: check authority, spam score and link trend of a list of domains.
• Competitor research: compare DA, linking domains and link growth over the last 60 days.
• SEO reporting: schedule a monthly run on your clients' domains and track DA and link gains.
• Lead scoring: add DA to a list of company websites to prioritise leads.

Input

Field	What it does
domains	Domains or website links, one per line. https://www.notion.so/pricing is read as notion.so
proxyConfiguration	Residential by default. Keep it: Moz blocks datacenter IPs

{ "domains": ["apify.com", "notion.so", "https://www.shopify.com/pricing"] }

Output fields

domain, input, domainAuthority, linkingRootDomains (number) and linkingRootDomainsText (as Moz shows it, like 12.2k), rankingKeywords and rankingKeywordsText, spamScore and spamScoreText, topPages (url, pageAuthority), topLinkingDomains (domain, domainAuthority), linkingDomainsDiscovered60d, linkingDomainsLost60d, linkingDomainsHistory (date, discovered, lost), mozUrl, scrapedAt.

Moz shows large numbers rounded (6.4m, 387.1k); the number fields are that rounded value. A brand new or unknown domain comes back with DA 1 and 0 linking domains, which is Moz's real answer for a site with no links.

Error codes (never charged)

errorCode	Meaning
INVALID_DOMAIN	Not a domain or website link
NO_DATA	Moz returned no metrics for this domain
BLOCKED	Moz did not answer after retries on new IPs; run again
NOT_REACHED, UNEXPECTED	The run timeout arrived, or something unforeseen broke; only that domain is lost

Pricing

Event	Per 1,000
Domain report delivered	US$ 7.00

1,000 domains cost US$ 7.00, residential proxy included. Duplicates in the input are checked once, error rows are free, and there is no Apify compute bill on top.

Limitations

• These are the metrics Moz shows on its free Domain Authority checker. Page-level metrics for any URL, the full list of backlinks and keyword lists are part of Moz Pro and are not included.
• Moz gives each visitor only a couple of free reports, so the Actor uses a new residential IP for every domain.
• This Actor reads public pages only. Domain Authority is a trademark of Moz; this Actor is not affiliated with Moz.

Changelog

• 2026-09-30, 0.1: first release. Bulk DA, linking root domains, ranking keywords, spam score, top pages, top linking domains and 60-day link history, residential proxy included, free error rows.
