What does it all mean? I understand it is some measure of popularity in search engines, but how is it derived? I mean if you type my domain in google I come up 3rd, but that isn’t what I am going after. If you type in backgammon or backgammon articles I’m not on the first page.
I have a PR4 on my home page, but zeros on other pages. Does this mean if I link to someone from my home page it is worth more than from a page with a PR 0?
