Bulk Domain Authority Checker - Backlinks & Referring Domains

Check the authority of hundreds or thousands of domains in one run. For each domain you get a 0-100 domain rank, referring domains, total backlinks, the dofollow/nofollow split, spam score, broken links, link types, top linking countries and TLDs. You can also add new and lost links over the last 30 days. It's a fast, low-cost Ahrefs and Moz alternative for bulk domain checks. Invalid domains and domains with no backlink data are free.

What you get

For every domain you enter, one row with:

• domainRank: authority score from 0 to 100, based on the number and strength of referring domains (similar in spirit to PageRank, Domain Rating or Domain Authority). mainDomainRank is the rank of the root domain, which is useful when you check subdomains.
• referringDomains and referringMainDomains: unique linking domains and linking root domains, plus nofollow versions of each (domains sending at least one nofollow link)
• backlinks, dofollowBacklinks, nofollowBacklinks and dofollowRatio (0-1)
• referringIps, referringSubnets and referringPages: how diverse the link sources are, which helps spot link networks
• textBacklinks, imageBacklinks and redirectBacklinks, plus otherBacklinkTypes (canonical, alternate, meta and so on)
• spamScore: 0-100 spam score of the link profile; higher means riskier
• brokenBacklinks and brokenPages: links that point at pages returning errors
• firstSeen and lostDate: when the first backlink was found and when the last one was lost
• topCountries, topTlds and platformTypes: where the links come from (for example {"US": 812, "DE": 120}, {"com": 640, "org": 95}, {"cms": 300, "blogs": 120})
• Optional 30-day changes: newBacklinks30d, lostBacklinks30d, netBacklinks30d, newReferringDomains30d, lostReferringDomains30d, netReferringDomains30d, and root-domain versions
• status: ok, no_data (free), invalid (free) or error (free, retry later)

Export to JSON, CSV, Excel or Google Sheets from the Dataset tab, or use the API.

Use cases

• Link building and outreach: filter a prospect list down to sites above a minimum domain rank before you send a single email
• Expired domain and domain flipping research: screen thousands of domains for real authority, spam risk and link diversity in one run
• Competitor analysis: compare domain authority, dofollow ratios and link growth against competitors
• Guest post and PBN vetting: catch sites with inflated metrics, few referring IPs, high spam scores or links that are collapsing
• SEO agency reporting: track referring domains and 30-day new and lost links for every client domain on a schedule

How to use

1. Paste your domains into Domains, one per line. Full URLs are fine: https://www.example.com/blog?ref=1 is checked as example.com. Subdomains such as shop.example.com are kept.
2. Optional: set Minimum domain rank (0-100) to keep only domains at or above that rank.
3. Optional: turn on Include 30-day new & lost links to add link velocity to every row.
4. Run the actor. Results appear in the Dataset tab, one row per domain.

Duplicates are removed automatically, so each domain is checked and billed once per run.

Pricing

• A small fixed fee per run, plus a fee for each domain checked that has backlink data.
• Turning on 30-day new & lost links adds one flat fee per run (not per domain).
• Domains that are invalid, have no backlink data, or fail to load are not charged.
• Minimum domain rank filter: domains below your minimum are still checked and are charged, even though they don't appear in the dataset. The filter saves you sorting time, not money. The run's status message tells you how many domains passed and how many fell below.
• Free plan: check up to 3 domains per run (current metrics only, no 30-day changes), 2 runs per day, 60 minutes apart, so you can try the output. Upgrade to a paid Apify plan to remove these limits.

FAQ

Is domain rank the same as Ahrefs DR or Moz DA? No tool shares the same scale, but all of them measure the same thing: how many strong sites link to a domain. Use domainRank to compare domains with each other and to track changes over time.

How are dofollow and nofollow backlinks counted? nofollowBacklinks is the number of backlinks with a rel="nofollow" attribute. dofollowBacklinks is all remaining backlinks.

What does "no data" mean? No backlinks were found for that domain. This is common for brand-new or parked domains. These rows are free.

Can I check individual pages? This actor checks whole domains and subdomains. Paths in your input are removed.
