I have about 12 different dvds that I need to sell. Would it be better to list them all on one domain name like howtovideosite.com The dvds are subject by 4 dvds are guitar lessons 6 dvds are fitness videos 1 dvd is making money with stocks 3 dvds are how to massage. would it be better to have a domain name for each product by subject or list them all under 1 domain name? for example learnguitarfast.com homefitnessvideos.com makemoneywithstocks.com howtomassagevideos.com wouldn't it be a lot less work to put them all on one domain name?
