Page Rank, Domain Authority And Page Authority

[peterlee1768]

Hello everyone! Let me explain what is the main difference about page rank, domain authority and page authority?
Please someone illustrate domain authority & page authority.

Hey Peter, here is a brief differentiation:

Page Rank: Quality metric invented by Google’s owners Larry Page and Sergey Brin. The values 0 to 10 determine a page’s importance, reliability and authority on the web according to Google.

Page Authority: Describe the probability that a specific page from your site will be found on a search engine. Page authority is based on a logarithmic scale from 0 to 100 and deals with the relevance of information and links within site pages to one another.

Domain Authority: Measure of the power of a domain name and one of many search engine ranking factors. Domain authority is based on three factors: Age, Popularity, and Size.

Thanks lilysmith22 to differentiate above three.

Can someone explain which (domain authority or page rank) we should prefer for directory summation, forum posting, blog commenting sites or any other SEO activity.

Concentrate on having content worth reading and let the search engines do their job.
