How is it different than posting on Facebook for free?

Without Facebook Advertising, a post made about your lost pet is only going to be seen by your friends and maybe their friends – even businesses that offer to post on their page for free will do little good (unless someone just happens to come across the post). With Facebook Advertising, we create a post on our page and then pay Facebook to have it displayed to people that live around where your pet went missing – it will especially reach people that may have seen your pet, but are not actively looking for the owner. A single sighting of your pet can make all the difference in focusing your search.
