I have 2 sites, one is 6 mo. old, and the other is 2 mo. old. I exchanged many links with both sites, (the older one does have twice as many backlinks, though) but the newer site is now PR=3 and the older one is still PR=0. The older one gets lots more traffic, and has adsense code on it. I don't get it.
Is it the site in your sig and neither are returning backlinks on google... Google does only take a sample but if your sample is 0 it tells you that you'll in need of some more backlinks.. Hope that helps..
Well, liquid-nutrition-vitamins.com has 95 backlinks and www.liquid-nutrition-vitamins.com has 142 backlinks in MSN and Yahoo. None in Google, but it gets a PR=3. My other site has 215 backlinks in MSN and Yahoo, (the www. version has 159) none in Google, and has a PR=0. Weird..
I am in the same boat man. With the recently Google update, I no longer have any links. However, when I look at other sites with my topic and that have links back to me, I see several. You mentioned that Google only takes a "sample"....this is interesting, never heard it before, but very plausible.
i dont think you should worry that much about PR its not really that important because lately you see more and more sites with low PR doing well in google SERP. continue your linkbuilding and you should be good
i agree with acatmusic, if you worry about the work, such as link building etc.. the rewards of higher pagerank and higher rankings will come with time and work.
You must be need to Increase your back links to 300+ Google not increase your PR if you've 1k or 2k back links, your back links increase by High PR back links and hits,etc. You must be need to wait at least 4 - 5 month. also improve your seo.
