Page Authority & Domain Authority

[GAZ09]

Hi Guys,

I am trying to educate myself a much as possible about link building to get higher positions.

Please can you tell bit more about Page Authority & Domain Authority ? Also how important are these factors really?

Thanks

As I understand it, they are pretty self-explanatory in that "Page Authority" is the authority of a specific page based on its content.  And "Domain Authority" is the authority of an entire domain/website (ie. CNN.com has a massive domain authority).

Often times you will comes across an article on something and notice that that article itself is a PR6, while the homepage of that same site might only be a PR2-4.  That page has developed a significant Page Authority, whereas the domain has not.

Domain Authority always trumps Page Authority, in my opinion.  For example, getting a backlink to your site off a relevant website with a higher Domain Authority is always going to play better for you than getting a link off a page where the domain doesn't carry much weight.  That's just been my experience.
