Page Authority (PA)
01 Definition
Page Authority (PA) meaning: Moz's 0 to 100 score predicting how well a single page may rank in search.
Page Authority is a Moz metric, scored 1 to 100 on a logarithmic scale, that predicts a specific page's ranking potential based on its link data. It is model-driven and best used to compare pages, not as an absolute grade. PA is Moz's proprietary score and not used by Google to rank pages.

Why it matters
How Page Authority (PA) fits the work
It gives a page-level comparison metric, helping you gauge which URLs carry more link strength when planning links or content.
In context
The product page scored a Page Authority of 38, higher than the blog post's 22, reflecting its stronger link profile.
Practical note
PA is relative and recalibrated over time, so scores can shift without your page changing. Compare pages within the same period rather than tracking a lone number.
