I think I found a good niche for a product on Amazon. Is it effective to promote the product via Twitter who users who posted a newsarticle link? I've started to register a few different Twitter handles, and have started a few scripts to gain followers. But these scripts are basically based on a list of followers from a niche-related account. How does one build followers based on a link in Twitter? Is this even a worthwhile method? Newb here.
