An Overview of Differences between Domain Authority & Page Authority
- What is Domain Authority?
Domain authority (DA) is a score that predicts how well a website will be shown on search page result pages (SERP). DA is calculated on a logarithmic scale ranging from 0 to 100. Domain Authority is computed by evaluating linking root domains, some total links, MozRank, MozTrust and about 40 factors and using all of those factors to make it into a single DA score. This score hence can further be used to compare websites or tracking their “ranking strength” over time.
- How do I check my DA score?
Now the next question arrives: How Do I check my DA score? You can test a website’s DA score by using MozBar (a free Chrome-extension), or the SERP Analysis section of Keyword Explorer, and many other SEO tools available all across the web. You all know about sites like Wikipedia, Google, Facebook right? These websites have a very DA score which in return gives them a high rank in SERP whereas websites which don’t have that much of inbound links may have a much lower DA score. All brand new sites will always start with a Domain Authority score of one.
- How Do I increase DA Score?
Domain Authority can’t be targeted to be influenced directly as it is made up of an aggregate of other metrics that each have an impact on the authority score. You might think that it was some un-natural thing but it was done intentionally, this parameter is meant to measure the competitiveness of a given site in Google search results. The best way that you can influence Domain Authority is to improve your overall search engine optimization is commonly known as SEO. You got to focus on your link profile by getting more links from other well-linked-to pages.
- What is Page Authority?
Page authority (PA) is a term used for describing the probability that a particular page from your site gets found on a search engine. Page Authority is scored just like DA on a 100-point logarithmic scale. Similar to DA, it’s significantly easier as well to grow your PA score right from 10 to 20 in comparison to increase from 70 to 80. The algorithm used for calculating Page Authority is being updated hence the PA always fluctuate from time to time. Page Authority is based on data from the Mozscape web index that also includes MozRank, MozTrust, link counts, and many other factors. It also makes use of a machine learning model to identify the algorithm that correlates with rankings across the thousands of SERPs. Importantly, it doesn’t take specific on-page elements into consideration like keyword use or content optimisation.
- How Do I Check My PA Score?
Page Authority metrics are also incorporated into various online marketing platforms across the web and it’s always fluctuating than DA which has a much stable score. Hence it’s hard to have a general idea of a PA score it can go up or down anytime.
- How Do I Increase My PA Score?
Similar to Domain Authority, Page Authority is also difficult to target directly. It is made up of an aggregate of metrics that has an impact on the score. As Google considers different factors into account while ranking a page, consequently a metric that tries to calculate it must also require incorporating a lot of factors as well. The best way to influence a Page Authority is to improve its link profile, which controls its MozRank and MozTrust scores can be accomplished by getting external links from other high-authority pages, which in turn act as “vote of confidence” for the authority of your page.
Domain Authority and Page Authority scores work similarly. As both of them are scaled on a 100-point system, after each update, the recalculations of a score mean that Authority score of a given page/site could go up or even go down even no matter that particular page/site has improved their link quantity and quality. This is the nature of a relative scaled system, and so these authority scores are best viewed as comparative results rather than absolute metrics.
