What is the Bulk Domain Authority Checker?

This tool allows you to check a domain’s Page Authority (PA), Domain Authority (DA), and spam metrics for up to 50 URLs at a time.

What Is Domain Authority (DA)?

DA is a metric created by Moz that ranges from 1 to 100, representing how authoritative a site is likely to be perceived by search engines like Google. Metrics such as the number of high-quality backlinks, unique number of referring domains, and the strength (i.e. DA) of those domains increase a site’s DA. Getting backlinks from websites with high DA is strongly correlated with improving your content’s ability to rank in search engine results.

What Is Page Authority (PA)?

PA is also a Moz metric that represents the amount of link equity is on a given page. The higher the PA, the more likely a page will be to rank on search engine results. The number of high-quality off-site links to a page and the number and strength of internal links pointing to a page improves its PA.

How to use a Bulk DA Checker?

This bulk domain authority checker tool is a useful SEO tool that allows you to determine how authoritative different websites are. It’s a popular tool for search engine optimization professionals focused on link building. The authority scores for domain and page authority signify how much link equity would be transferred from a “do-follow” outlink from a specific site or page if it linked to your site. Increasing domain authority through building links has been quantitatively shown to improve your site’s ability to rank well in search engines for your content/keywords. The Moz Trust and Moz Spam Score metrics tend to be less meaningful when you study larger website datasets, but on occasion can help you spot and avoid low-quality websites.

Why did we build the Bulk DA Checker?

We used just about every DA checker tool out there and had issues with tools frequently breaking, running slowly, or prevented us from quickly checking authority on multiple URLs at the same time. We integrated our systems with the Moz API so that we could analyze our database of millions of domains programmatically. We’ve built a variety of SEO tools for our clients, including link analyzers, rankings checkers, website authority monitors, chrome extensions, and others. We are offering this SEO tool to help you as well… and of course, it is completely free to use! Happy DA/PA Checking!

Why isn’t DA a perfect indicator?

Remember that Google doesn’t actually use DA or PA in its calculations. These metrics are just proxies to help us understand what Google is seeing when it looks at a website. All Moz Rank metrics are fallible, just like Alexa Rank. Moz’s DA calculations are limited by its ability to fully index the web as fast as Google indexes the web. Moz’s calculations of website authority don’t dampen the value of links coming from comment spam and other spammy link building techniques.
