What does PA (Page Authority) mean?

Page Authority (PA) is a metric created by Moz that scores a single webpage’s ability to rank in search engines, on a scale from 1 to 100. It’s calculated based on factors like the number and quality of backlinks, internal links, and other SEO signals pointing to that specific page.

Unlike Domain Authority (which measures the strength of an entire site), Page Authority focuses on individual URLs.

Example

“Our article on social media strategies has a Page Authority of 42, making it one of the strongest SEO assets on our site.”

What are ways to use Page Authority in your business?

Use PA to evaluate the SEO potential of your key landing pages or blog posts. Focus your link-building efforts on important pages to raise their authority and improve rankings. When analyzing competitors, compare PA scores for similar pages to identify SEO opportunities.

You can find PA scores using SEO tools like Moz, Semrush (via alternative metrics), or Ahrefs (with comparable link strength metrics).

Pro Tip

A page with low PA can still rank well if it satisfies search intent and has high-quality content - use PA as a guide, not a rule.
