Welcome to the forums, hungry - sorry I didn't get to welcome you in the other thread.
Others have been describing that kind of strangeness (major increase in traffic, no apparent improvement in rankings) at various times in the past year. It'd hard to understand how that could be - clearly more traffic should mean your rankings improved for at least one query term, you'd think.
Can you see if your increase in Google traffic was across the board, or confined to just a certain search terms or landing page on your site?
