The URL is in my signature " Football Picks " Football Picks, NFL Picks and Free Football Picks When I switched I droped off completly for thiose keywords and I am Nowhere for these words. Also I have totally re done my site in the last couple months. Let me know what I need to do to rank well. Thanks for any help. and please don't be afraid to hurt my feelings.
Sounds like you will have to start all over again. However you will have a base of incoming links for different keywords to the ones you are targetting. I could give you the SEO spiel but im sure you already know all that. I think you will have to build up a lot of links with your anchor text. when you redid your site was it optimised? Its probably best to start there.
