It is simple, but you've confused me already. :-)

"All I know is I want conversion tracking for the past year on my site"
If you don't have conversion tracking in place already, when you do install it, it can't look back in time.

Wordpress, I hear ya. Do you sell products and have the AdWords Conversion Tracking script installed on your receipt page?
