CMS Google positioning
 

When I was running vb 3.x.x my site was posted on the first page of a google search. I seem to have lost the position with 4.0.1 Gold and also the blogs aren't getting out. I have added many keywords and metatags still not finding hits. Is there something I am missing or is there a trick to getting the site out there again with 4.0. Gold

Thank in advance
Don
