Sponsor a video contest in which customers create a one-minute video about why they like your business, products or services. Ask them to send the videos to you and post them to your Facebook page. Invite visitors to vote on which video should win a cash or merchandise prize. Include an email opt-in on your Facebook page. Be sure to follow Facebook’s rules regarding contests.
Some ad platforms will ask more of your landing pages than others, when running ads. For example, AdWords is much stricter, when compared to Facebook. AdWords typically requires that you do not have a ‘thin,’ site that is designed solely to collect leads. Because of this it might be a good idea to focus on using Facebook or Twitter, to begin with.
