What would happen if Google didn't display the PageRank information anymore?


If the PageRank information wasn't available anymore, webmasters wouldn't concentrate on a little green bar in their web browser but on more substantial factors.
For example, you could ask yourself the following questions if you want to optimize your web site:
Does my web site has enough content that is interesting to web surfers and search engines?
Is my web site linked to other web sites that have similar content that might be interesting to my web site visitors?
Do other web sites with related content link to my web site so that people who are interested in what I have to offer can find my web site?
Does the web page I want to trade links with offer interesting content (no matter what PageRank it might have)?
Ironically, that is exactly what Google expects from webmasters. On its official webmaster pages Google writes: "Make pages for users, not for search engines. [...] Would I do this if search engines didn't exist?".
