Page Authority (PA) is a metric developed by Moz, a well-known company in the SEO industry. It’s designed to predict how well a specific page will rank on search engine result pages (SERPs). Rather than evaluating the strength of an entire website or domain, as Domain Authority does, Page Authority considers the ranking power of a single page.
PA is scored on a logarithmic scale of 0 to 100, with higher scores indicating a greater ability to rank. It considers numerous factors in its calculation, predominantly based on link data, including the number of linking root domains and the number of total links, among other factors. It’s worth noting that getting a PA from 30 to 40 is easier than moving from 70 to 80 due to the logarithmic nature of the scale.
While Page Authority provides a good indication of the competitive strength of a particular page, it’s essential to use it in context. For instance, comparing the PA of one’s webpage with competitors’ pages targeting the same keyword can give valuable insights into the competitive landscape. However, using it in isolation might not yield actionable results, especially since Google considers hundreds of factors in its ranking algorithm.
SEO professionals typically focus on enhancing their link profile by gaining high-quality, relevant backlinks to improve Page Authority. However, it’s crucial to remember that, like all third-party metrics, PA is a prediction, not a guarantee. Google doesn’t use Page Authority in its ranking algorithm. Thus, while it offers a helpful barometer for SEO efforts, it should be complemented with other metrics and considerations.
In summary, Page Authority serves as a valuable tool in the arsenal of SEO practitioners, providing insights into the potential ranking strength of individual pages in the vast landscape of the web.
