Do you mean, making money by writing posts? then YES Opportunities like PPP, SR, blogervertize etc.. are all networks, which pays for writing reviews/posts!
most sites online that offer money to write post just dont sound promising to me, I am sure hundreds of people sign up and probably only make a few cents, and if the sites do pay high, there are 5000 other people out there trying to get picked to write the same post, so your chances would be very slim on getting picked.
Yes, but only if you like making a max of $50 a month for the rest of your life working for 8 hours a day. This isn't a good way of making money online
Depending upon the niche of your website and the PR and alexa rank you might get higher offers from the PPP type companies.
I know lots of people that blog for pay and make way more that 50 dollars a month and are hardly ever at that computer -lol- that's a sterotypical assumption. And you know what happens when we a$$ume.
