If you have access to your website's code, you can add the Facebook pixel yourself. Simply place the Facebook pixel base code (what you see when you create your pixel) on all pages of your website. Then add standard events to the pixel code on the special pages of your website, such as your add-to-cart page or your purchase page. For full step-by-step instructions on adding the Facebook pixel to your site, visit the Help Center. Facebook Data Center
Whether someone is ready to book a trip or is just looking for travel inspiration, match their intent with items from your travel catalog. If they were browsing hotels but didn’t make a reservation—or if they were looking at flights but didn’t book a trip—travel ads let you show them relevant ads based on their specific dates, destinations and other trip details.
