Google Vs. Yahoo SEO

[azdeltice]

Here is an issue that is driving me nuts.

I have a site that I am webmaster for (www.glendalelax.com). Before we updated to SMF from a static site, it was tops in Google. Now, it is not visible down to the 6th page of results. However, on Yahoo, the site is number one. The search words used on both engines are glendale lacrosse league.

We have SEO4SMF on there as well as sitelinks setup in google.

Any suggestions would be greatly appreciated.
