What is page authority and how does it affect SEO?

Page Authority (PA) is a score developed by Moz, a leading SEO software provider, which predicts the likelihood of a specific page ranking in search engine results. The score is measured on a logarithmic scale from 1 to 100, with higher scores indicating greater potential for ranking.

Page Authority is based on a variety of factors, including the link profile of the page and the overall strength of the website. The score is designed to give SEO professionals and website owners an idea of how well a specific page is likely to rank compared to other pages.

Page Authority affects SEO in several ways:

1. Helps in Competitive Analysis: By comparing the Page Authority scores of different pages, you can get an idea of how competitive a particular keyword or topic is and how difficult it may be to outrank the current top-ranking pages.
2. Guides Link Building Efforts: If you're trying to improve the ranking of a specific page, you can use the Page Authority score as a guide for your link building efforts. Pages with lower Page Authority scores may require more links to improve their ranking potential.
3. Informs Content Strategy: Pages with high Page Authority scores are often good targets for promoting and sharing, as they're more likely to rank well in search results. By focusing on creating high-quality content that's likely to earn links and social shares, you can improve the Page Authority scores of your pages and increase their ranking potential.

It's important to note that Page Authority is just one of many factors that can affect the ranking of a page. Other factors, such as the relevance and quality of the content, the overall strength of the website, and the presence of technical SEO issues, can also impact a page's ranking potential.
