Check domain authority in bulk, free
This free bulk domain authority checker scores a whole list of websites in one run. Paste up to 10 domains, one per line or separated by commas, and each one gets its Moz Domain Authority, Page Authority and Spam Score, Majestic Trust Flow and Citation Flow, domain age and referring domains in a single sortable table.
It counts against the same 10 free checks a day as single reports, with no account and no captcha. Duplicates and invalid entries are removed before the check, so a messy list pasted from a spreadsheet works fine.
Bulk limits by plan
| Plan | Domains per run | Best for |
|---|---|---|
| Free | 10 | Quick checks of a short prospect list |
| Starter pack | 30 | Weekly outreach and guest post vetting |
| Pro pack | 100 | SEOs who check sites every day |
| Agency pack | 250 | Mass domain authority checks for teams and client work |
Packs are one time payments, with no subscription. See the pricing page for the price per check.
How to use a bulk DA PA checker well
- Paste your list and run the check.
- Sort by Spam Score and remove anything above 30%.
- Sort the rest by Moz DA to see the strongest sites first.
- Check that Trust Flow is at least half of Citation Flow on the sites you keep.
- Open any row for the full report, including WHOIS and topical Trust Flow.
- Export to CSV or copy the table into Google Sheets and keep it for next month.
If the metrics in the table are new to you, our guide to what counts as a good domain authority explains the ranges.
What people use multiple domain checks for
- Guest post and link prospect lists: remove pumped sites before you pitch or pay.
- Competitor research: score every site ranking on page one for a keyword.
- Expired domains: compare authority, spam risk and age across auction lists.
- Client reporting: track a portfolio of sites with the same metrics every month.
Need a verdict between a few finalists rather than a list? The single domain checker gives each site a full report, and the compare tool puts up to four side by side.
Understanding the metrics
No single number tells the whole story. Read authority, trust and age together to judge how competitive a domain really is.
- Domain Authority1 to 100
- Predicts how likely a whole domain is to rank in search results, based on the quality and quantity of its linking root domains. It is logarithmic: moving from 70 to 80 is much harder than 20 to 30.
- Trust Flow0 to 100
- Measures link quality by how closely a site is linked to a hand-reviewed set of trusted seed sites. Higher means the backlink neighborhood is more reputable.
- Citation Flow0 to 100
- Measures link volume and influence without judging quality. Read it alongside Trust Flow: a TF/CF ratio near or above 1 suggests a clean profile.
- Domain AgeYears
- Time since the domain was first registered, taken from its live WHOIS record. Older domains tend to have deeper link histories, though age alone does not drive rankings.
- Spam Score1 to 100%
- The share of sites with similar features that Google penalized or banned. 1 to 30% is low; above 60% means the site's links and content deserve a closer look.
- Referring DomainsCount
- Unique websites linking to the domain. Usually a stronger authority signal than the raw backlink total.
