^ 100% this. I bootstrapped my business through Instagram influencers. You have to be extremely targetted around the audience. When judging if an influencer is worth working with, figure out who their audience is and the nature of that interaction. For example, Imagine I sell an awesome new cat toy for helping shy cats be more social. I don't want to find the cat pages with millions of followers. I want to find the cat expert person who helps their small group of followers deal with their shy cats. Micro-influencers also work really well. If you can get a person to talk about a product to their group of friends, the ROI is usually much higher than these giant pages. You just have to have a lot of them.
