Page reputation (PA) is a score developed by Moz that predicts how well a given page will rank in search engine results pages (SERPs). Page authority scores range from 1 to 100, with higher scores corresponding to a greater ability to rank.
Page reputation is based on data from the web index and takes dozens of factors into account. Similar to Domain Authority, Page Authority scores are generated using a machine learning model that defines the algorithm best matching the rankings among thousands of SERPs. It then uses that specific calculation to generate Page Authority scores.
How to Calculate Page Reputation?
Page reputation is plotted on a logarithmic scale of 100 points. That’s why increasing your score from 20 to 30 is much easier than raising it from 70 to 80. The algorithm used to calculate page authority is continually updated, so you may notice changes in your score from time to time.
“Good” What is Page Authority?
How page reputation is calculated is best used as a comparative measure (rather than an absolute, tangible score) when searching search results and determining which pages may be stronger. As a comparative tool, there is no such thing as a “good” or “bad” page authority score.
Comparison of Page Authority and Domain Authority
Page reputation measures the projected ranking strength of a single page, while domain reputation measures the strength of entire domains or subdomains. However, the metrics are calculated using the same methodology. In many ways, they are more similar than they are different.
Technical Definition of Page Reputation
Page reputation is calculated in the same way as domain authority, but at the individual page level. Page Authority is based on data from the Mozscape web index and includes a range of factors, such as the number of backlinks and over forty other elements. Importantly, it does not take into account specific on-page elements such as keyword usage or content optimization.
Like domain authority, page authority is calculated using a machine learning algorithm and therefore fluctuates as the data fed into the algorithm changes. Therefore, it’s best to use Page Authority as a relative measure for comparing against other pages rather than an absolute value that “scores” a page’s rankability.
How Do I Affect Page Reputation?
Like domain authority, page authority is a holistic score and is difficult to influence directly. It consists of a total set of measurements, each of which has an impact on the score. This multifactorial dependency is intentional. Google evaluates numerous factors when ranking a page, so any measurement attempting to assess this must also consider multiple factors.
The best way to influence the authority of a page is to improve its link profile. This can be achieved by acquiring external links from other high-authority pages that serve as “votes of confidence” for your page’s authority.
