Only Numbers Aren't Metrics: DA and PA Are Your Site's Pulse of Authority

When we're talking about "authority" in SEO, what we're talking about is how your site is trustworthy, credible, and trusted by search engines such as Google. Trust has a measurable component in two scores:

  • Domain Authority (DA):

A search engine ranking metric from Moz that predicts the likelihood of a domain to perform.

  • Page Authority (PA):

Like DA, but rather than displaying the power of a whole domain, it displays a specific page.

PA and DA are both 1-100 scores, and the higher your score, the bigger your chance to dominate the others.

If you ever find yourself thinking, "How to know how my website is doing in credibility?", the first thing is to look at DA and PA using a correct DA PA checker tool.

Why in the world would marketers do that to themselves, monitoring their DA and PA so closely? Because Google does take into account a lot of ranking signals, and although DA isn't exactly an explicit ranking signal, it just so happens to be highly correlated with SERP performance.

Having these scores up to date gets you:

  1. A better understanding of the health of your site's link profile.
  2. Something to reference which to compare your site to in terms of sites for your competition.

A quantifiable metric of your SEO progress.

A DA PA checker tool is a software or web tool where you put the website URL and obtain its domain authority and page authority values instantly. The majority of these softwares also have other SEO-related features, like backlink check, spam score indicator, and competitor check.

  • High-quality backlinks count
  • Root domains pointing
  • Spam score (a flagging indicator of toxic backlinks)
  • Site architecture and technical SEO considerations
  • Page speed, mobile-friendliness, and user experience signals

When and Why Should You Check DA and PA?

Including DA and PA checks in your bi-weekly or monthly SEO review gives you real-time feedback on whether you are on the right track or not. You can check if your off-page SEO (e.g., link building) is paying off for you and if the competition is getting a lead.

Descriptor Bullet Point:

  • Strategic SEO Planning:

Periodic tracking puts you in a situation where you can make adjustments in a timely manner. For example, if your DA score is still not improving despite continuously updating content, then you may possibly need to put greater emphasis on generating good-quality backlinks as opposed to merely writing blogs.

A general step-by-step approach is as follows:

  • Choose a Reliable Tool:

Start with Moz, Ahrefs, or any other reliable free DA PA checker tool on the internet.

  • Take Action:

This is an ongoing process. The SEO world is constantly changing—your DA now may be yesterday's news next week if your competition ups the game.

Spam Score: The Sneaky Metric That Can Kill Your DA

All good DA PA checker tools will also have a spam score measurement. This is a measurement based on the quality of backlinks to your site. If your site is hit with an onslaught of backlinks from spam, irrelevant, or lower-tier sites, your spam score can increase even as your DA remains high.

An increasing spam score is bad because it can result in:

  • Less trust on Google's algorithm.
  • Lower ranks.

Manual penalties in the event of not disavowing toxic links.

Get rid of or redirect all 404 pages to conserve SEO juice.
