PA stands for Page Authority, a metric predicting a specific page's ranking ability on SERPs.


Page Authority (PA) is a score developed by Moz that predicts how well a specific page will rank on search engine result pages (SERPs). It ranges from 1 to 100, with higher scores indicating a greater ability to rank. PA is calculated using an algorithm that considers dozens of factors including link counts and the quality of those links. It's similar to DA (Domain Authority), but PA focuses on the strength of individual pages rather than the entire domain.

Usage and Context

PA is primarily used in SEO and digital marketing to assess the strength of a single webpage's capacity to rank on SERPs. It helps marketers prioritize pages for content optimization and link-building efforts based on their potential to climb in search rankings.

When comparing pages of a similar topics or within competitive niches, high-PA pages are typically given precedence for enhancements. Moreover, PA is often used alongside other metrics like DA and keyword competitiveness to provide a comprehensive view of a page's standing and areas for improvement.


  1. How is PA different from DA?

    • PA focuses on the ranking strength of a single page, while DA assesses the entire domain's ability to rank.
  2. Can PA change over time?

    • Yes, a page's PA can increase or decrease based on factors like changes in its inbound link profile or the introduction of stronger competing pages.
  3. How can I improve a page's PA?

    • Improving PA involves enhancing the page's content quality, increasing the number and quality of inbound links, and optimizing on-page SEO elements.
  4. Does a high PA guarantee top rankings on SERPs?

    • While high PA can indicate a page's potential for better rankings, it doesn’t guarantee top positions due to other factors like content relevance and search algorithm updates.
  5. Where can I check a page's PA?

    • PA can be checked using tools offered by Moz, including the MozBar browser extension and Link Explorer.


  • Targeting Efforts: PA helps prioritize SEO efforts towards pages with the most ranking potential.
  • Benchmarking: It serves as a benchmark to measure improvements in a page's SEO performance over time.
  • Competitive Analysis: Comparing PA scores can provide insights into the competitive landscape and reveal opportunities.


Understanding and monitoring Page Authority is crucial for SEO success. It serves not only as a benchmark for assessing the potential of individual pages to rank but also guides marketers in resource allocation for optimization tasks. Improving PA in conjunction with overall SEO strategy can lead to significant gains in visibility and traffic from search engines.
