i built 15 web 2.0 sites six months ago. each is targeting a similar keyword phrase related to my money site. my money site is an amazon affiliate site. i only get a bout 2-6 visitors per day and this month already i've earned $100 in sales. i believe if i can scale up and get more visitors i will make a lot of money with the site. what should i do now with these 15 web 2.0 sites to help boost my money site? should i buy fiverr gigs and blast them with spam or what? what is the best thing to do?
