Mind postng the site? If not wrong section I can give you a tip though use adsense there are more ways but without knowing your blog niche its hard
u can earn thorught adsense and many other publisher prg. or affiliate product selling. http://www.google.com/adsense Note: u should start new thread in general business or adsense section or request moderator to move this one in right category.
Well you can even earn by some affiliate programs.. register in cj.com and put relevant ads on your site.
well, just get traffics and create interesting topics and contents I am sure ppl will click and buy just need to add more topics and stories place google adsense is a good idea some affiliates products is also good it never hurt to try to put things on your blog, just don't over saturated with affiliate products still traffics is the most important Money Source
