What is page authority (PA)?

Page Authority (PA) is a metric developed by Moz that predicts the likelihood of a specific page ranking well on search engine results pages (SERPs). It is similar to Domain Authority (DA), but while DA measures the overall strength of a domain, PA focuses on the ranking potential of a specific individual page within that domain.

PA is calculated using a machine learning model that takes into account several factors, including:

Backlinks: The number and quality of backlinks pointing to the page.

Internal Links: Links from other pages within the same website pointing to the target page.

Content Quality: The relevance and quality of the content on the page.

Social Signals: While less influential, social engagement can play a role in PA.

Key Points About Page Authority:
Range: PA scores range from 0 to 100, with higher scores indicating a greater chance of ranking higher in search engine results.

Predictive Metric: It is not a direct ranking factor used by Google, but rather a predictive tool to assess how well a page might perform in SERPs.

Influenced by Backlinks: The number and quality of backlinks to a page significantly influence its PA. Pages with high-quality backlinks tend to have higher PA.

Domain Authority (DA) vs. PA: While DA measures the overall authority of a domain, PA focuses on individual pages. A page with a high PA may perform better in search results even if the overall domain has a lower DA.

How to Improve Page Authority (PA):
Build Quality Backlinks: Earn backlinks from reputable, relevant websites in your industry.

Optimize On-Page SEO: Improve factors like content, keyword optimization, and technical SEO to increase the page's chances of ranking well.

Create High-Quality Content: Pages with valuable, informative, and original content are more likely to attract backlinks and improve PA.

Promote Your Content: Use social media, email marketing, and outreach to drive traffic to the page and increase its exposure.

PA can be a valuable metric for assessing the strength of individual pages on your website and determining areas for improvement to boost search engine rankings.
