Page authority (PA) is a score that indicates the likelihood that a page will rank well in Google search results.
Page authority is calculated by taking into account several factors, including:
Google determines what pages are most likely relevant to users based on their search queries and browsing history. As a result, you should ensure that your pages have the highest possible Google ranking.
Also, your page will be linked by others if your content is more relevant and quality-focused.
The higher the PA score, the easier it is for a page to rank.
