Facebook retargeting can be used in a number of ways and is based on your advertising goals, or objectives. There are four main goals in retargeting ads: build awareness, reminder advertising, close a sale, and invite repeat business. When retargeting is used in conjunction with your advertising goals, ads become very effective and drive your return on investment up.
If you follow the 80-20 rule, you’ll use 80 percent of your Facebook posts to inform, educate, and entertain, and the other 20 percent to promote your brand. Remember that using Facebook for business is all about building relationships, and self promotion is not a great way to do that. But if you provide enough value, your audience will be open to learning about your products and services in those 20 percent of posts that are more sales-focused.
