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.
