Domain Authority Checker: Free Bulk DA & PA

This domain authority checker shows the Moz Domain Authority (DA) and Page Authority (PA) scores for up to 20 websites in a single run. Paste your domains one per line, and you get a results table you can compare at a glance and export. It suits competitor research, link prospecting and quick site audits.

What Is Domain Authority?

Domain Authority is a score from 1 to 100, created by Moz, that estimates how likely a website is to rank in search results compared with other sites. Moz builds the score from link data, mainly the number and quality of the websites that link to a domain. A higher score suggests a stronger link profile.

Two details matter before you rely on any number:

• It is a comparison score. The scale is logarithmic, so moving from 20 to 30 is much easier than moving from 70 to 80.
• It is not a Google metric. Google has said it does not use Domain Authority in ranking. Treat it as a useful proxy for link strength, not a ranking guarantee.

What Is Page Authority?

Page Authority uses the same 1 to 100 scale but predicts the ranking strength of one specific page instead of a whole domain. A site can have a modest DA and still have a high-PA page that earned many strong links. When you want to judge a single URL, such as a guest post target, the Page Authority Checker is built for that job.

How to Use the Domain Authority Checker

You can check domain authority for a whole list in under a minute. Follow these steps:

1. Find the box labeled Enter Domains (one per line, max 20).
2. Type or paste your domains, one on each line, for example example.com, another-site.com and third-domain.org. If you paste a full address starting with http:// or https://, the protocol is removed for you.
3. Watch the counter under the box. It updates as you type, for example "3 domain(s) entered", so you can confirm the list is right.
4. Use Clear if you want to empty the box and start over.
5. Press the check button. The input area is replaced by a results view with a progress bar and a running count such as "2 / 3".
6. Read the table as each row fills in. Every row shows the domain, its Domain Authority, its Page Authority and MozRank.
7. Press the export button to download the table, with the columns Domain, Domain Authority, Page Authority and MozRank, for a spreadsheet. To test a new list, use the link to start a new check.

Worked Example: Comparing Your Site With Two Competitors

Say you run a small gardening blog and want to know how far behind you are before planning a link-building campaign. You enter three domains: your own and two competitors. The values below are illustrative, but they show how the results read.

Here is the reasoning. Your DA of 18 sits in the red range, which is normal for a young or small site. The rival at 34 is about 16 points ahead, a gap you can realistically close with steady link earning over time. The large media site at 72 is not a fair benchmark for now. So your practical target is the rival's range, not the giant's.

The PA column adds a second clue. Your PA of 22 is slightly higher than your DA, which suggests your homepage has attracted a few links that the rest of the site has not. Spreading links to inner pages would help the whole domain.

How Do You Read and Act on the Results?

Each number is easiest to understand when you compare it with the other rows, not with a fixed target. The score badges are color coded to help: red for scores below 30, yellow for 30 to 59, and green for 60 and above.

Low scores (red, under 30)

Low scores are common for new sites and small local businesses. They do not mean the site is bad. Focus on earning a few relevant links from real sites in your field, publishing content people cite, and fixing broken pages that already have links pointing to them.

Middle scores (yellow, 30 to 59)

These sites have an established link profile. If you are outreaching to a site in this range, it is usually a respectable place to earn a mention. If it is your own site, look for the gap between you and the top competitor and study which kinds of pages attract their links.

High scores (green, 60 and above)

High scores come from many links from many different, trusted domains. They are hard to reach and hard to move. When you see one, ask whether the site is actually relevant to your topic, because relevance often matters more than the raw number.

Why does MozRank show N/A?

MozRank is an older Moz metric that Moz has retired, so the tool shows N/A in that column. This is expected, not an error. Domain Authority and Page Authority are the current metrics to use.

What if a row shows an error?

A row can show an error badge in place of scores when no result comes back for that entry. Check the spelling, remove extra characters, and run that domain again. Very new domains may also have no data yet.

Who Uses a Bulk DA Checker, and When?

A bulk DA checker saves time whenever you have more than a handful of sites to judge. Common situations include:

• Link prospecting. Paste 20 blogs from an outreach list and keep only those above a minimum DA, such as 30.
• Competitor benchmarking. Check your site and the top results for your main keyword in one pass.
• Buying or vetting a domain. Pair the DA score with a look at domain age and history. A high score on a brand-new domain deserves a closer look.
• Client reporting. Agencies can export a CSV and drop the numbers into a monthly report.
• Guest post vetting. Screen sites quickly, then check individual pages with the Page Authority tool.

If you work through a lot of domain research, the Domain Tools category groups related checkers in one place.

Best Practices, Common Mistakes and Troubleshooting

DA is most useful when you use it consistently and carefully. These habits keep your conclusions sound.

• Enter bare domains. Use example.com rather than a long page URL with parameters. Avoid spaces and put one domain on each line.
• Stay within 20. The tool accepts up to 20 domains per run. If your list is longer, split it into batches and export each one.
• Compare like with like. Check all competitors in the same session so the numbers come from the same snapshot.
• Track trends, not single readings. Scores shift as Moz updates its link index. Re-check monthly or quarterly and note the direction, not tiny changes.
• Do not chase the number. Buying cheap links to raise DA can backfire. Earn links that bring real readers and relevance.
• Check safety too. A high DA does not prove a site is clean. Before you pitch or link, run suspicious sites through the Suspicious Domain Checker, and if email deliverability matters, look at the Blacklist Checker.

My score looks different from another tool

Other providers compute their own authority scores with different data and formulas, so the numbers will not match. Compare scores only within the same metric, and use one source consistently for tracking.

My new site shows a very low score

A new domain starts near the bottom of the scale and rises only as it earns links. A low score here is a starting point, not a penalty.

Limitations to Keep in Mind

Domain Authority is a modeled estimate, not a measurement of actual traffic or rankings. A site with a low DA can outrank a high-DA site for a specific query if its page answers the question better. Scores can also lag behind recent link changes, so a link you earned last week may not be reflected yet.

The tool reports DA, PA and the retired MozRank placeholder only. It does not show backlink lists, traffic or keyword rankings, so use it as one signal alongside your own judgment.
