Video ads are shown only to the people you want and you only pay when they watch. In other words, you won’t waste money advertising to people who aren’t interested in your business. With over one billion users, you can select the audience you want based on age, gender, location, interests, and more. Plus, you only pay when they engage with your ad. If they skip it before 30 seconds (or the end) you don’t pay a cent. Use YouTube’s Analytics tool to understand who’s watching your ads and how they’re interacting with them. You have complete control over your daily budget, so you can spend what you’re comfortable with.
