If you are learning SEO or trying to improve your website ranking, you have probably come across the terms DA and PA. You might be wondering how to check DA and PA, as these two metrics—Domain Authority (DA) and Page Authority (PA)—are among the most commonly used indicators to measure how strong and trustworthy a website is in search engines.
But how exactly do you check DA and PA of a website? Which are the best free DA PA checker tools? How to use bulk DA PA checker extensions or even check DA PA in Semrush?
In this detailed article, you’ll learn everything about DA and PA — their full form, meaning, importance, and all free online methods to check your website’s DA/PA score.
What is DA and PA? (DA PA Full Form)
Before learning how to check them, let’s start with the basics.
- DA Full Form: Domain Authority
- PA Full Form: Page Authority
Both of these terms were developed by Moz, a leading SEO software company.
- Domain Authority (DA) measures the overall authority or credibility of an entire website. It ranges from 1 to 100, where a higher number means stronger authority.
- Page Authority (PA), on the other hand, measures the authority of a specific page (a single URL).
These metrics are not directly used by Google for ranking, but they provide a useful estimate of how likely your website or page is to rank higher in search results.
Why Are DA and PA Important?
Although DA and PA are not official Google ranking factors, they are extremely helpful for:
- Competitor Analysis: You can compare your DA and PA with your competitors to understand who has a stronger online presence.
- Link Building: Higher DA websites are considered more trustworthy. Getting backlinks from them improves your SEO score.
- SEO Progress Tracking: If your DA and PA increase over time, it means your SEO efforts are working.
- Client Reporting: SEO professionals often use DA/PA metrics to report improvements to clients.
