Social media. It’s all about sharing experiences. So this very popular form of communication is an essential part of travel marketing. Few people will book a holiday without checking online to discover what others think, or to view images of a place. But while Facebook and Twitter are valuable tools of the tourism trade, don’t discount the other kids on the social block. Snapchat, Instagram, Pinterest, Vine, all have one very important thing in common. They offer a feast for the eyes. Imagery is a critical part of the travel decision-making process, so sites specialising in photos and video are marketing gold.
