The other day I setup a Twitter account to promote a subgenre of electronic dance music. I added a repeating background image and did a bit of research to see which hashtags people were using most in the niche and then just starting tweeting out info and Amazon links to the songs and have been getting a decent amount of clicks within hours. Too soon to see if anything converts but I noticed that a few Twitter bots were monitoring the tags I used and started following and retweeting me. Hopefully it'll get some sales.
