Bulk DA, PA and Trust Flow checker
Paste or import a list of domains and get Moz, Majestic and Pretty metrics for every one, in a table you can sort, filter and export. One credit per domain.
- 01 Paste your API key, or sign in to skip that.
- 02 Add domains — one per line, or import a .txt or .csv file.
- 03 Fetch. Results append to the table below, so you can keep adding.
- 04 Sort, filter, and export what you want to keep.
Domain signals
Calculated from the figures already in the table — no extra request, no extra credit. The thresholds are explained on the metrics page.
Requests go directly from your browser to the API using the key you entered. Sign in to have them proxied instead.
Compare domains before you shortlist them
A bulk DA checker helps you work through an auction export, expired-domain list or outreach prospects without opening a separate page for every candidate. DomDetailer returns Moz Domain Authority and Page Authority, Majestic Trust Flow and Citation Flow, and Pretty crawl counts in one sortable table. The useful question is how a domain compares with others in the same subject and price range.
Use the numbers to reduce a long list, then investigate the remaining names. A high score alone cannot tell you whether a domain still gets visitors, whether its links survive a purchase, or whether its past content fits your plans.
What the columns mean
- Domain and Signals
- Domain identifies the result. Signals opens comparisons calculated from that row, including TF/CF and repeated-link patterns. These checks use no extra credit. A warning asks for inspection; a reassuring label is not a certificate that a domain is safe.
- Moz: DA, PA, Links, Rank, Spam and Trust
- Domain Authority (DA) estimates ranking potential for the domain; PA is the page-level score returned for its home page. Links is Moz's observed external link count. Rank and Trust are supporting link-popularity and trust measures. Spam Score is the risk field supplied by the API, not proof of a penalty. Compare the scores with the backlink sources, rather than treating a single cutoff as a buying rule.
- Majestic: TF, CF, Links and Ref Domains
- Trust Flow reflects proximity to trusted link sources; Citation Flow reflects link influence and volume. Links counts observed external inbound links, while Ref Domains counts unique linking domains. Reading TF beside CF and referring domains helps distinguish a broad profile from thousands of placements repeated across a few websites.
- Majestic: Ref IPs, Subnets, EDU, GOV and TTF 1–3
- IPs and subnets describe hosting diversity among referring sites. Shared hosting can explain concentration, so a small number does not prove a network. EDU and GOV identify links from those domain types; the actual page matters more than its extension. The three Topical Trust Flow columns pair subject categories with scores, useful for checking whether a candidate's link history matches your niche.
- Pretty: Links In, Links Out, Pages, EDU, GOV and DoFollow
- These are observations from the Pretty crawl and link index. Links In and Out describe inbound and outbound links; Pages counts crawled pages. EDU, GOV and DoFollow give additional inbound-link counts. A large outbound count may deserve inspection, but directories and resource pages can legitimately link widely. Read every count within its provider's coverage. The DA, Trust Flow and link-count field reference explains the individual API fields.
An illustrative domain result
This invented example explains the table. It is not a fetched result, an endorsement, or current data for example.com.
| Moz DA | Moz PA | Majestic TF | Majestic CF | Ref domains | Pretty pages |
|---|---|---|---|---|---|
| 32 | 35 | 18 | 30 | 120 | 85 |
Here TF/CF is 18 ÷ 30 = 0.60. That suggests trust is keeping pace with link volume under the tool's screening thresholds. It does not tell you whether those 120 referring domains are relevant, still link today, or would keep their links after the site changes. Open the backlink checker to inspect source pages and anchors before drawing that conclusion.
Work through a 5,000-row auction export
- Export the auction list as CSV or TXT. Keep a separate copy with prices, closing times and your notes; the checker reads domains, not auction terms.
- Import the file. The importer reads it in your browser, chooses the column containing the most domains, strips URL paths and removes duplicates within that file. Files must be under 8 MB.
- Review the loaded count and the chosen column. Clear existing input before importing a fresh batch; domains already in the textarea or result table are not automatically removed.
- Confirm your balance, then fetch. Five thousand submitted domains represent 5,000 credits. Requests run with limited concurrency; leave the tab open and allow the batch to finish.
- Sort and search the results to make a shortlist. Use CSV or Excel to save the displayed dataset; exports respect the table's search filter. Keep the original auction file so you can match domains back to their prices.
- Inspect backlinks and historical content for shortlisted candidates. Record the reasons for your decision, rather than automatically bidding on every domain above a DA or TF threshold.
Save the shortlist, then investigate
Repeated fetches are additional requests. If a batch contains errors, retain the successful export and retry only the domains you still need. For recurring lists, the Windows bulk domain checker or the domain metrics API may fit your workflow better.
Read the expired-domain review workflowCost per 1,000 domains
At 1 credit per request, 1,000 domains use 1,000 credits. That is $1.36 of the 25,000-credit pack's value, or $0.79 at the largest pack's unit rate. These are usage equivalents: you buy a whole pack, starting at $34. Credits do not expire. See all credit packs and domain-checking prices before starting a large batch.
Bulk checker questions
Is this a free bulk DA checker?
The browser interface has no separate fee, but fetching domain metrics uses DomDetailer credits. Each domain request costs 1 credit. Buy a credit pack or sign in with an existing account. Credits never expire and there is no monthly subscription.
Do I need my own Moz or Majestic subscription?
No. DomDetailer provides the licensed Moz and Majestic metrics alongside its own Pretty counts through the same domain request. Your DomDetailer API key is sufficient; you do not need to enter separate provider keys.
Can I check 5,000 domains from an auction export?
Yes. Import a TXT or CSV file up to 8 MB. The importer chooses the column containing the most valid domains and removes duplicates within that file. Check the loaded count before fetching. Each submitted domain uses a separate request; keep the tab open until it finishes.
Does a high Domain Authority or Trust Flow guarantee a good purchase?
No. These are third-party link metrics, not a guarantee of traffic, Google rankings or a clean history. Compare relevant candidates, inspect actual backlinks and archived content, and check the domain for trademarks and suitability before bidding.
Why do the providers return different link counts?
Moz, Majestic and Pretty use different crawl indexes, coverage and update schedules. Their counts are not interchangeable. A blank field can mean data was unavailable; it should not be read as a confirmed zero. Rechecking is another domain request and uses credits.
