Buying Facebook ads

In her new course, Sarah Staar recommends buying ads on Facebook. Does this method still work as well as it used to? Would something like Solo Ads work better?

Yes, it works the best. Social Media Marketing has emerged as a whole lot of new career.

If you don't know how to do that, I would recommend you to hire a freelancer by posting in the "Hire a Freelancer" section and your job will be well-taken care of.
