Introducing 7 Best DA Checker of 2021
Marketers, SEO people and website owners all end up checking the domain authority of other sites sooner or later, and usually for more than one site at a time.
Plenty of websites will show you a domain authority score, but you need one that gives an authentic number. Every tool uses its own algorithm, which is why your site can score one number on one tool and a different number on the next.
Below are the domain authority checkers I trust to give an accurate figure.
What is Domain authority and why it needs to be checked?
Domain authority is a score created by Moz, an SEO tools company, and calculated from several factors.
It runs from 1 to 100, with 1 the lowest and 100 the highest. It is broadly true that a high score helps a site rank higher in search engines.
That is because the factors behind the domain authority number are similar to the ones search engines use to rank pages.
A domain authority checker earns its keep when you are writing a guest post for another website or getting a backlink.
There are different reasons for checking the domain authority and some of them are written below:
- When writing a guest post for another website
- When giving or getting a backlink to or from other websites
- When buying or selling a website
- For checking the optimization of a website
- For checking the authority of a website
- For checking the quality of the website because the domain authority helps to indicate the quality of the content and links
These tools will check the domain authority of any website, yours or your competitor’s.
1. MOZ Domain Authority Checker
Moz is a popular SEO blog and tools website, and domain authority is one of its tools. It is the most authentic and up to date source, because domain authority is Moz's own score.
The tool is free. You only need a free Moz account to check the domain authority of any website.

Along with the domain authority, this website also lets you know the spam score, linking domains, and some other information like page authority.
My favourite part is the Chrome extension, which shows the domain authority the moment you open a website.
2. PrepostSEO DA Checker
SEO people and website owners often need to check domain authority in bulk, and pasting links one at a time into a single URL checker gets old fast.
Prepostseo lets you check up to 500 URLs at once, with no registration or subscription.

It also has a RAW data option: paste any text and the tool pulls the links out of it for you.
After extracting, it will automatically check the domain authority for multiple URLs and you can use it for any purpose.
Along with the domain authority number, this website also tells the Spam score, page authority, IP address, and some information.
Extra options let you exclude duplicate IP addresses and check the indexed pages of each URL you test.
Prepostseo also has a chrome extension that allows you to check the DA anytime without opening a new tab and then website.
3. SEO Weather
This is another website that can help you to know the domain authority of a website and you can check bulk domains at the same time.
The SEO weather allows you to check the domain authority, page authority, Page Rank, IP, address, as well as Spam Score.

This website includes some additional options like downloading the bulk data in an Excel sheet. This way, you can easily use it for any purpose.
4. Bulk Site checker
The Bulk site checker is another tool that can scan multiple sites at the same time. If you are watching multiple competitors at the same time then this tool can help you.
You can check up to 10 URLs at a time, and it also uses the Moz APIs for its results, so the domain authority is accurate whether you are vetting a guest post or a backlink.
Along with the domain authority, it also tells the Page rank and IP address which helps you to know some more information about the website you are searching for.

5. Bulk DA checker
This is another popular Bulk DA checker which is quite efficient and accurate for providing the domain authority score of bulk domains.
One search covers up to 5 domains, and alongside domain authority it shows Page Authority, Moz Rank, Backlinks, Alexa Rank, IP Address and Google indexing.
6. Rushax
Rushax offers several tools, and its domain authority checker gives you that one result.

You get the domain authority in a simple interface and nothing else, not even bulk checking.
7. Marketmegood
Marketmegood.com is a bulk domain authority checker that is free and instant. It stands out because it checks up to 20 URLs in a single click.

You don’t need to register or buy the subscription; you just need to open the link and enter the URLs for finding the Domain authority.
Conclusion
Lots of websites show domain authority, but the best ones pull fresh data from the Moz APIs.
Before considering the domain authority checker, you should see whether it is providing an authentic result or not. If the tool is using the real-time MOZ APIs then it would be better for checking any website’s domain authority.

Why Domain Authority Checkers have Different Scores?
Since different tools have a different method and basis to decide your domain authority, that's the main reason you will see a variation of DA score on different Tools.
-
Does Domain Authority Really Matter?
It depends on why you are checking it. No search engine uses Domain Authority, so it has no direct effect on ranking. It is a yardstick for the strength of your backlink profile, along with spam score.
-
Ahref and SEM Rush showing Different DA Score.
That difference is expected, because each tool uses its own method and algorithm to calculate Domain Authority (DA).
-
Can we Increase Domain Authority Manually?
Not with 1 click. You raise it by earning good backlinks from high authority websites.
-
Do Backlinks Matters in Domain Authority?
Yes. Backlinks are the main factor in domain authority.
