Creating a Custom Convesion in Facebook allows Facebook to track important events that take place on your website. Doing this, enables you to optimize your Facebook ads for conversions. What this means, is Facebook will track how many people convert from your ad and then go find more people who look like those people to try and get them to convert for you. By showing your ad to the people most likely to convert for you, your ad gets better results at a lower cost.
If you have a business, you need to advertise. So, where do you advertise? You advertise where the people are . . . more than that, you advertise where YOUR customers might be. Want to know a secret? That place is Facebook. Nearly the entire population is represented on Facebook. If you want to know where YOUR customers are, I’ll tell you . . . they’re on Facebook. Because Facebook has made it hard for business pages to get the exposure they need in the Facebook Newsfeed, you need to advertise in order to reach the people you want to reach. The good news . . . Facebook is a highly effective and low cost advertising platform when done properly.
