Social media is an ever changing world, and businesses are still developing new ways to market themselves on the various platforms available. You don't have to share your secrets to success on marketing necessarily, but I'd love to hear what methods you use to promote yourself or your business and how effective those methods are. Do you monetize your YouTube videos? Do you promote your posts on Twitter or buy Facebook ads?
I've found that Facebook ads are really quite cost effective for the reach they get, and the $5 or $10 I've spent on them has garnered me a good amount of traffic to my business page. No confirmed sales as of yet, but more traffic is always good!
