my website's been running for about a little over a month now and i'm getting some decent traffic. i know the value of getting links on search engine rankings. i used the links popularity check and saw that i had 24 links to my site and over half of them were from pages on my own site. my google PR is 0... does this mean i'm not indexed? also, if i buy a couple of links from high ranking websites, how much would my rankings improve? my competion have about 200-300 links (but none from google).
