What is the best (& quickest) way to improve my site's page rank?

I have tried submitting the address to other sites...
---------------------

On the google toolbar, it has a yelow smiley face... if i click this 1000 times, will it improve my rank? and will google know it was me all the time?

thanks,

KGB

That smiley face will do nothing to improve your pagerank. You need content and lots of it. This way people will link to you. When you have alot of backlinks and Google decides to do a PR update (about 4 times a year) then you might recieve some PR.

OK, thanks... what is the smily face for then?

It's to vote for a site that you like but I have no clue whether its actually useful. I have never heard of any real use for it in their algorithm.

ok, thanks
