Domain Authority

Domain Authority scores are a SEO ranking matrix created by a SEO Consulting business called Moz (similar to Google’s Page Rank).

The DA score is a combination of many factors, primarily being content driven. While there are plugins available to help with the technical side of SEO (for more information, please review the WordPress plugin depository), there are no magic bullets to high rankings. If there was, everyone would be doing it (leading to the magic bullet becoming irrelevant).

I recommend you start by learning more about ranking. You can find many articles by Googling “DA Moz rankings”
