Page Authority (PA) is a value score assigned to webpages by search engines, indicating the probability of the page ranking in search results. It represents the level of trust and value search engines attribute to a specific page, and is calculated based on factors such as the quality and quantity of links pointing to the page. Page Authority scores range from 0 to 100 and are an indicator of a page’s likelihood of ranking well in search engine results.
The difference between PageRank and Page Authority is that the former is an algorithm that focuses on the quality and quantity of links, while the latter considers multiple factors such as content quality and relevance. Page Authority can be improved when a page with a high PageRank score links to it. Google no longer allows measurement of PageRank, but you can evaluate your site’s ability to rank using Semrush’s Authority Score.
Page Authority is determined by search engines through complex algorithms, taking into account factors such as the quality of inbound links and the relevance of the page’s content. Authority Score, which is a compound metric graded by Semrush, is calculated based on link power, organic traffic, and spam factors. The Backlink Analytics tool can be used to check the Authority Score of a page.
A good Page Authority score is generally considered to be at least 50. It should be judged against similar websites in the same niche, rather than compared to all other pages on the web.
To improve Page Authority, creating quality content, earning backlinks from trustworthy domains, and reducing spam factors are helpful. Other factors to consider include age and trust, popularity, and the freshness of the last update.
Various factors such as algorithm changes, website updates, or increased competition can impact Page Authority. Page Authority, Domain Authority, and link authority together contribute to the success of SEO efforts.
Domain Authority provides a measurement of an entire domain’s authority, and is similar to Page Authority, whereas link authority measures a backlink’s power and influence. Semrush’s Authority Score measures a domain’s authority based on link power, organic traffic, and spam factors.
Improving and analyzing Page Authority can be done through tools like Backlink Analytics, in order to understand and analyze Domain Authority, Page Authority, and backlink quality to improve the overall performance of the website.
