I always see this guy advertising his services on Twitter: https://twitter.com/xposure4all?lang=en Basically he built an account and he offers to Tweet about your business, website or social account. He advertises his service by tweeting about it on the account itself. I was thinking of doing something similar, but with accounts in some specific niches. For example of one of my accounts was about nutrition, I would say "Advertise your nutrition product here!" Good idea, or not?
