An authority score is a qualitative measure that determines how visible and ranking a web property is in search results.
As Most SEO experts focus on authority, and for good reason. The main purpose of most SEO tactics, such as producing informative content and building links, is to increase authority.
What is Page Authority(PA)?
Page Authority (PA) is a metric that is used to measure the strength of a specific page within a website. It is similar to Domain Authority, but instead of measuring the strength of the entire website, it measures the strength of a single page. The score is represented on a scale of 0 to 100, with a higher score indicating a more authoritative page.
Page Authority is calculated by analyzing a variety of factors, such as the number and quality of backlinks pointing to the page, the relevance and content of the page, and the overall popularity of the website. Pages with a high Page Authority are more likely to rank well in Google SERP (search engine results page), as they are considered to be reliable and trustworthy sources of information.
Factors Impacting Page Authority:
There are several elements that are used to calculate Page Authority, including:
- Number of Backlinks: The number of backlinks pointing to a specific page is one of the most important factors used to calculate Page Authority. The more high-quality backlinks a page has, the more authoritative it is considered to be.
- Quality of Backlinks: The quality of the backlinks pointing to a specific page is also important. Backlinks from reputable and high-authority websites are considered to be more valuable than those from low-authority websites.
- Relevance of the content: The relevance of the content on the page to the backlinks and search queries it aims to rank for is also important.
- Popularity: The popularity of the website as a whole, as measured by factors such as the number of visitors and social media shares, can also be taken into account when calculating Page Authority.

The score is then represented on a scale of 0 to 100, with a higher score indicating a more authoritative website.
A website with a high domain authority is considered to be a trusted and reliable source of information and is more likely to rank well in search engine results.
