I'm experimenting with a few twitter bots that I've made, and I'm wondering, what's the best strategy for acquiring followers? I already have a database of tweets that I send out every once in a while.. but how do I find out who to follow? So far, I've just been following random people, and then sometimes I jump into somebody's followers and start following them. I'm not sure if this is the best strategy, as most of my followers are a bunch of "belieber" idiots. I've heard some people target keywords, is that via the search option?
