Page Authority (PA) is a score that predicts how well a specific page on a website will rank in search engine results. This score is created by SEO companies like Moz and typically ranges from 1 to 100, with higher scores indicating a stronger potential for ranking. The score is based on several factors, such as the number of links to the page and the quality of those links.
Page Authority helps website owners understand how individual pages might perform in search results compared to other pages.
How is Page Authority Calculated?
Page Authority is determined by algorithms that look at various factors related to the page. Some of the most important factors include:
- Backlinks: The number and quality of other websites linking to the page. Pages with more high-quality links tend to have higher authority.
- Content quality: Pages with well-written, relevant, and useful content are more likely to earn high Page Authority.
- Site structure: How the page fits within the overall structure of the website, including how easy it is for search engines to crawl and index it.
The calculation is based on machine learning models, so the exact formula can change as search engines and SEO practices evolve.
Why is Page Authority Important?
Page Authority is useful because it gives you an idea of how likely a specific page on your website is to rank in search engine results. A higher PA score means the page has a better chance of appearing at the top of search engine results pages (SERPs), leading to more visibility and traffic.
Although PA is not an official ranking factor used by search engines like Google, it is a helpful metric for comparing the strength of different pages.
Page Authority vs. Domain Authority
It’s important to note that Page Authority measures the strength of a single page, while Domain Authority (DA) measures the overall strength of the entire website. Both metrics are useful, but Page Authority focuses on individual pages, which can help you see which specific parts of your site are performing well.
