Page Authority Checker

Page Authority (PA) is a metric developed by Moz, a company that provides inbound marketing software, which predicts how well a specific webpage will rank on search engine result pages (SERPs). It is based on a logarithmic scale from 0-100, with higher scores indicating a higher predicted ability to rank. The metric is calculated by evaluating various factors such as the number and quality of links pointing to the webpage, its overall popularity, and other factors.

It's important to note that these metrics should not be the only factor to judge the performance of a webpage, since they are not the only metric that search engines use to rank the pages. It is important to have a comprehensive view of your website performance and optimize it according to search engine guidelines, along with the user experience.
