I don't personally run paid ads for my video courses but whenever I ask people what almost prevented them from signing up, a huge portion of the answers say they didn't know the course existed. Reviews aren't enough for discover-ability, but they are awesome once you know the product exists. I'm not convinced paid ads are the right move for me, but I do think general advertising (having someone talk about a product or service on a site that isn't yours) is absolutely essential.
