What is Page & Domain Authority..?
 

Someone please tell me about it I heard it yesterday, really curious about it... !

Page Authority predicts the likelihood of a single page to rank well, regardless of its content. The higher the Page Authority, the greater the potential for that individual page to rank well in search results.Domain Authority represents SEOmoz's best prediction about how a website will perform in search engine rankings. Use Domain Authority when comparing one site to another or tracking the “strength” of your website over time.
