Free Bulk DA & PA Checker

DA is a score created by Moz to predict website rankings on search engine results pages (SERPs). Scores range from 1-100, with higher scores indicating a higher chance of a good ranking. There are many major factors that go into determining a DA score including the number of high-quality backlinks, quality internal links, the number of unique referring domains, and the overall moz domain authority of said domains. Generally speaking, getting backlinks from websites with high moz domain authority is strongly connected to building your own site’s DA.

Google is generally seen as the dominant search engine, meaning its ranking will be one of the most important SEO metrics for any site. Google will use an algorithm or a collection of algorithms to make decisions about its rankings. It’s important to note that DA is not used as a direct metric to determine their SERPs.

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.

Page Authority (PA) is a score developed by Moz that predicts how well a specific page — not the whole domain — will rank on search engine results pages (SERPs). Like Domain Authority, PA runs on a 1-100 scale, where a higher score signals a stronger ability to rank. It is calculated primarily from the quantity and quality of links pointing to that individual URL, along with the authority of the referring pages.

The key difference: Domain Authority estimates the ranking strength of an entire website, while Page Authority estimates the ranking strength of a single page. Checking DA and PA together gives you a fuller picture — a high-DA site can still have low-PA pages that need more internal links or backlinks to compete. Use the bulk DA & PA checker above to see both metrics for every URL side by side.

We used practically every domain authority checker tool we could find to quickly check the authority of multiple URLs at the same time.
