I have a website has 53 doamin rank. Nowadays it's more important from having PR rank instead of Domain Authority .
Why Domain Authority is most important for SEO?[domain-authority]Matt Cutts’ announcement heralds the end of an area, really, because quick-fire guest blogging was one of the last vaguely acceptable techniques by which one could quickly manipulate rankings. While Google’s tougher stance has got some online marketers upset, others have applauded Cutts for tightening up this final area in which wild-west-SEO’ers could ply their trade. Now, almost for the first time since the birth of the internet, the playing field has begun to level out. Webmasters who put time and effort into their design, online communities and content creation are going to set the standard from now on.
What is domain Authority?
Domain authority is a measure of the power of a domain name and is one of many search engine ranking factors. Domain authority is based on three factors: Age, Popularity, and Size.
SEO gurus Moz can be credited with the metric known as DA or domain authority. Moz’s own search algorithm gauges the quality of any given site based on a huge complex combination of factors including onsite and offsite, taking in to account things such as diversity of Backlinking domains to come up with a score between 0 and 100. A brand new site, for example, will have 0 whereas a very high authority site might have 80/100. Domain Authority gives those working in the field of online marketing a useful metric by which to consider the apparent quality of any site.
Technical Definition of Domain Authority
Domain Authority is Moz’s calculated metric for how well a given domain is likely to rank in Google’s search results. It is based off data from the Mozscape web index and includes link counts, MozRank and MozTrust scores, and dozens of other factors. It uses a machine learning model to predictively find an algorithm that best correlates with rankings across thousands of search results that we predict against.
It’s best to use Page Authority (PA) and Domain Authority (DA) as comparative metrics when doing research in the search results and determining which sites/pages may have more powerful/important link profiles than others. While specific metrics like MozRank can answer questions of raw link popularity—and link counts can show the raw quantities of pages/sites linking—the authority numbers are high-level metrics that attempt to answer the question, “How strong are this page’s links in terms of helping them rank for queries in Google.com?”
Where can you Find Domain Authority?
Domain Authority metrics are incorporated into dozens of SEO and online marketing platforms across the web.
You can measure Domain Authority using Open Site Explorer or the MozBar, Moz’s free SEO toolbar. Moz incorporates Authority metrics into all Moz Analytics campaigns, as well as the Mozscape API.
SEO Best Practice
How do I influence this metric?
Unlike other SEO metrics, Domain Authority is difficult to influence directly. It is made up of an aggregate of metrics (MozRank, MozTrust, link profile, and more) that each have an impact on this score. This was done intentionally; this metric is meant to approximate how competitive a given site is in Google.com. Since Google takes a lot of factors into account, a metric that tries to calculate it must incorporate a lot of factors, as well.
The best way to influence this metric is to improve your overall SEO. In particular, you should focus on your link profile—which influences MozRank and MozTrust—by getting more links from other well-linked-to pages.
