Bulk Domain Authority Checker
Check Domain Authority, spam risk and domain age for up to 100 URLs at once. Every score comes with the exact signals behind it — no black box, no captcha, no signup.
Bulk Authority Checker
Paste up to 100 URLs. Get Authority, Risk, and Age for each — with the exact signals behind every score. Live public data, no captcha, no signup.
Uses a server. Each domain is queried against multiple public data sources (Open PageRank, RDAP, Wayback, Safe Browsing, URLhaus, DNS). Nothing is stored beyond a short cache. Every score can be traced to its source.

Scope
What it is, and what it isn't.
Every tool on ToolsVale is scoped to one job. Here is exactly what this one does, and what it does not — so you know whether it fits before you start.
What it is
- Checks Domain Authority, spam risk and age for up to 100 URLs in one run. Bulk-scale link prospecting, backlink auditing, and competitor domain vetting in a single paste.
- Shows the exact signals behind every score. Every point on every score is traceable to its public data source — no black-box ML, no proprietary index.
- Detects live threats using real-time intelligence feeds. Google Safe Browsing, URLhaus and Spamhaus DBL are queried at check time, so hacked or newly-listed domains are flagged today, not next month.
What it isn't
- Not Moz DA. Moz's Domain Authority is proprietary and paid. For a Moz-branded number in a client report, use Moz Pro directly.
- Not a full backlink analyzer. We report referring-domain counts but don't list individual backlinks, anchor text, or link gain/loss over time. For that, use Ahrefs or Moz Link Explorer.
- Not a Google ranking predictor. Authority scores estimate link-profile strength for comparison purposes — they don't predict where a domain will rank. Use Google Search Console for real rank data.
- Not a page-level score. Scores are at the domain level, not per URL. Page-level authority is on the roadmap.

How to use it
Bulk Domain Authority Checker
Bulk Domain Authority Checker
in three moves.
01
Paste your URLs
Drop up to 100 URLs into the box, one per line. Naked domains, https:// prefixed URLs, and messy Excel-copied pastes all work. Duplicates and subdomain variants are auto-removed.
02
Watch it stream
Click Check authority. Each row appears as its signals finish arriving — no black-box wait. Filter live by Best prospects, Risky, or Weak authority as results come in.
03
Click "Why?" on any row
Every score expands into its full breakdown: which signals contributed, from which source, with what weight. No other authority tool shows you this. Export the whole report as CSV or Excel when you're done.

Why this one
Built against the ways these tools disappoint.
We ran the same files through the popular alternatives first. These are the gaps we found, and what this tool does instead.
01
Most free DA checkers cap you at 5 URLs, ask for a captcha, and serve month-old cached data
This one runs 100 URLs per run at 500 per day free, no captcha ever, and shows the last-checked timestamp on every row so you know if a result is fresh or cached.
test: Paste 20 URLs. It streams the first row in under a second and finishes in 10-20 seconds. Every competing free tool caps you at 5-20 URLs, gates the rest behind signup, and shows a static spinner while it works.
02
Every other tool gives you a number with no way to check the reasoning
Every score here expands into its full breakdown: the Open PageRank value, referring-domain count, domain age from three independent sources, HTTPS + MX signals, and every risk flag with its source (Google Safe Browsing, URLhaus, Spamhaus DBL, TLD reputation).
test: Click "Why?" on any row. Nobody else shows you this — Moz doesn't, and neither does any free checker built on Moz's API.
03
Spam scoring here uses live threat intelligence, not a 2020 snapshot
Moz Spam Score is based on 17 static flags. This tool checks Google Safe Browsing, URLhaus, and Spamhaus DBL in real time — so a domain that got hacked or listed in the last hour is flagged as risky today, not next month.
test: Filter by Risky. Every flag names its source and the exact reason, with severity. Nothing is inferred.
04
Honest about what it isn't
The score is called "Authority" not "Moz DA" because we don't have access to Moz's proprietary index. This tool uses Open PageRank as the anchor signal (computed from Common Crawl's open web graph) plus 7 corroborating signals. For most link-prospecting decisions the number is directionally identical to Moz DA. For the few cases it isn't, we tell you which signals were missing so you can decide whether to trust it.
test: Look at the confidence field. Any row where more than two signals failed is flagged low-confidence — you'll never get a made-up score.
The detail
How this actually works.
Check Domain Authority, spam risk and domain age for up to 100 URLs at once. Every score comes with the exact signals behind it — no black box, no captcha, no signup.
A bulk domain authority checker helps you evaluate many websites at once — filtering strong domains from weak ones, and safe ones from risky ones, before you commit outreach time or money. It’s a useful workflow for link building, guest posting, and competitor research.
Most free tools in this space are wrappers around Moz’s paid API, often combined with ads and captchas. This tool takes a different path: instead of relying on Moz data, it combines free public data sources such as Open PageRank, RDAP, Wayback, certificate transparency logs, and threat-intelligence databases into a transparent composite score. Every number is traceable to its source.
What the scores actually mean
Authority Score (0-100) is a weighted composite based on link graph position, referring-domain signals, domain age, HTTPS presence, and business email infrastructure. It is designed to help you quickly compare domains. When important signals are missing, the confidence level drops instead of showing a fabricated number.
Risk Score (0-100) measures how safe a domain appears to be right now. It combines threat-intelligence signals, TLD reputation, expired-and-flipped-domain detection, and suspicious pattern checks. A hacked or newly flagged domain can be identified using current available signals.
Domain Age is estimated using three independent sources: RDAP registration data, the first Wayback Machine snapshot, and early SSL certificate records from crt.sh. The tool uses the available historical footprint to provide a broader view of the domain’s age.
Why we don’t call it “Moz DA”
Domain Authority is Moz’s proprietary metric and cannot be reproduced exactly without access to Moz’s proprietary index and model. This tool does not claim to provide an identical Moz DA score.
Instead, it uses Open PageRank as an authority signal and combines it with other public signals to create a transparent composite score. The result is designed for evaluating and comparing domains for prospecting and research purposes.
How to read your results
The report shows three main values for every domain: Authority, Risk, and Age. Score labels help you quickly understand whether a domain appears strong, moderate, weak, clean, or risky.
Evidence indicators show the underlying signals, including Open PageRank, referring-domain data, HTTPS status, MX record availability, and threat flags.
Click Why? on any row to view the detailed breakdown. You can see the available signals, their sources, normalized values, and their contribution to the final score.
Use the available filters to quickly identify your best prospects, risky domains, or domains with weak authority. Export filtered results as CSV or Excel to share them with your team or clients.
When to run a check
| When | Why it matters |
|---|---|
| Before a guest-post outreach campaign | Qualify prospects before spending time on weak or risky websites. |
| Auditing a backlink profile | Review potentially risky domains and backlinks. |
| Before buying a link or placement | Check whether the website appears to justify its asking price. |
| Competitor research | Evaluate competitor backlink opportunities and potential prospects. |
| Domain acquisition | Review an expired or aged domain before purchasing it. |
| Monthly prospect review | Re-check domains because authority and risk signals can change over time. |
What this tool cannot do
Every SEO metric has limitations. Here are the important ones to understand before using the results.
| Limitation | Why |
|---|---|
| It is not Moz DA | The score uses public signals and is not identical to Moz’s proprietary metric. |
| Backlink data may be incomplete | Public web data sources cannot provide a complete commercial backlink index. |
| No topical relevance scoring in v1 | Domain strength does not automatically indicate relevance to your niche. |
| Historical age signals can vary | Different data sources may contain different historical records for a domain. |
| Daily usage limits apply | Rate limits help prevent abuse and keep the tool available for everyone. |
| Some external data sources may be temporarily unavailable | Third-party services can occasionally rate-limit or fail during a request. |
How this compares to alternatives
Many free authority checkers use limited third-party data, restrict the number of domains per check, or require users to complete captchas. ToolsVale is designed to make bulk domain analysis easier by allowing up to 100 URLs per check with no signup or captcha.
| Tool | Free URLs per run | Signup | Captcha | Score transparency |
|---|---|---|---|---|
| ToolsVale | 100 | No | No | Detailed signal breakdown |
| Many traditional DA checkers | Usually limited | Varies | Often required | Limited |
The goal is simple: check more domains in less time while understanding where the scores come from. Instead of relying on a single hidden metric, you can review multiple authority, risk, and historical signals before making a decision.

FAQ
The questions people actually type in.
What is a bulk DA checker?
A tool that checks Domain Authority (or an equivalent authority metric), spam risk, and domain age for many URLs at once. It's how link builders, SEO agencies, and publishers qualify prospects in bulk instead of one at a time.
Is this the same as Moz DA?
No, and we're upfront about it. Moz DA is proprietary — nobody outside Moz can reproduce their exact score for free. This tool uses Open PageRank (computed from the open Common Crawl web graph) as the anchor signal, combined with seven other public signals into a transparent 0-100 composite. For most link-prospecting decisions the number is directionally identical to Moz DA. Where it differs, our confidence indicator flags it.
Why don't you use the Moz API?
Two reasons. First, the Moz API costs $75-500/month depending on volume — which would force us to add signup gates, captchas, or rate limits like every other "free" DA checker. Second, black-box scoring is bad for the person doing the prospecting: you can't verify why a domain scored what it scored. We built this to fix both problems.
How many URLs can I check for free?
100 per run, 500 per day from a single IP address. No signup, no card. If you need more, contact us — we're happy to raise the limit for genuine users.
Are the scores cached?
Yes, for 14 days per domain, to keep the tool free and fast. Every row shows a cached badge when it's a cache hit, and a timestamp so you know how fresh the data is. Force a live refresh by adding a query string to the URL (v2 coming).
What does the Risk score mean?
A 0-100 score where higher = riskier. It combines live threat intelligence (Google Safe Browsing, URLhaus, Spamhaus DBL — checked in real time), TLD reputation (risky new-gTLDs like .tk, .top, .xyz), expired-and-flipped-domain detection, missing HTTPS, and suspicious pattern heuristics. A score above 30 means "investigate before linking"; above 60 means "avoid."
What does "Age unknown" mean?
It means RDAP, Wayback, and crt.sh all failed to return data for that domain within our timeout window. Usually a temporary rate limit on one of those services. Try that specific URL again in a few minutes.
Why is the age wrong on some domains?
Occasionally crt.sh returns SSL certificates from a differently-named prior owner of the same domain, which makes the domain look older than it really is. If RDAP is significantly newer than Wayback, the row is flagged "re-registered" — a common spam pattern.
Does this affect my Google rankings?
No. Domain Authority (Moz's or ours) is not a Google ranking factor. Google has confirmed this repeatedly. What DA does is give you a standardized, comparative way to estimate a domain's link-profile strength — useful for evaluating prospects, not for predicting rank directly.
Can I use this via API?
Not yet publicly. If you want programmatic access, contact us — an API and MCP server are on the roadmap.
Is there a Chrome extension?
Not yet. It's on the roadmap.
How do I export the results?
Filter to the view you want (All / Best prospects / Risky / Weak), then click Download CSV or Download Excel. The exported file contains every column you see plus the raw signal values. Copy URLs (visible) copies just the URLs of the filtered rows to your clipboard.
What if I need more than 500 URLs a day?
The daily limit protects our free API budget. If you have a genuine bulk need, contact us via the ToolsVale contact form and we'll raise your limit.
