Link quality over quantity is the key. A few good 1-way links from authority sites with few other outbound links and high PR is far better than having lots (100s or even 1000s) of links from pages with low or no TBPR. Like anything else worth working towards, quality links take some effort/$/relationships to secure. Also, make sure that links appear naturally and not all at once as Google apparently will flag influx of inbound links if it appears unusual to Google.
Yes bro i believed that before that PR is all about links. But after what ive observed links has a little to do with PR.
Could you please explain how Google.com is a PR10?
I think you need to observe longer personally... How many links you have built is irrelevant if they are from sources where the inbound weight is discounted or not counted at all, like ROS links may be.
Personally, I would highly recommend going after quality rather than quantity and making sure the links you get pass PR if it's PR you're after...
I'd like to add that I measure quality purely by whether the site looks like a good resource whose traffic might find our site a helpful additional resource. No matter what the toolbar says. Everyone starts out with a low PR, and if the site has substance, it won't stay that way for long - you'll be happy to be in on the ground floor.
