I have a landing page with a lot of content on it, yesterday I checked the PR (never did this before, why would I do it with a landing page?) and it showed PR5, I was like huhh? so I checked with a few other sites and I was amezed my site was PR5 now I know google is freaking out at this time. but the links build to the site are pretty good. lot's of link wheels and pyramids done with AMR, BMD, Sick submitter, magic submitter and SEOnukeX also a lot of .EDU and .GOV links this site was the first on I did SEO on and pretty much did a lot of it. but now my question, it is a niche site and there are a lot of CB products to promote in the niche,. should I make another sales page and turn the site in good review site?
