My review sites im very simple, one page webs with a list of all the different benefits of each. Screenshots of each site im promoting plus i make it clear as to what there payment options are.

I did have alot of extra bits and odds on the sites but i found the conversions increased when i ripped the extras off !

I confess that i rip other peoples review sites, change there urls and upload them as mine to a link that is already getting relative traffic. Youd be suprised as to what templates convert better than others. Ripping other peoples sites is the quickest roleout to test new landing pages in my eyes
