Hi. I have a question perplexed my mind.. Yesterday,I checked my backlink number by three different backlink checker. I got the same results.. I had 450 backlink from the signature part of different forums.. However,when I check my page simply writing the title in Google search engine, The result is only 10 backlinks. I see only 10 link for my webpage from those forums.. What is my real backlink number, 10 or 460? I know all of those backlinks are with 0 pr value.. Another question is, if I have 5000 backlinks from 0 pr value forums,How many hits I can get?
Well I'd perhaps go run your domain in the yahoo search bar with link:www.mydomainname.com and see what you get there as well. If you had 5000 backlinks from pr0 forums...well I'd expect some movement in the rankings depending on how quickly you got those links...it could end in bad news.
For some reason, Google's backlink checking system just doesn't work as well as Yahoo and others you may be using. As for your second question, instead of trying to build 5000 PR 0 backlinks, I'd try to find a handful of PR 3-5 links instead. They'd be just as valuable as your 5000 PR 0 links and it would take you much less time. Plus, you wouldn't have to worry about the penalty that linkbuildr speaks of.
Check your Google backlinks in the Webmaster Tools found in your google account, this has the definate number of backlinks
