In the paper “The Guide to Social Media Images for Business” we are going to focus on the importance of images in social media marketing. In the beginning, we are going to present the types of images encountered on social media platforms (e.g. photos, GIFs and memes), and some strategies that underpin them. Moreover, we are going to look into elements that can help every company personalize its own social media materials. In order to create a brand, each person/company has to create its own “signature”, a number of elements that appear on all social media posts so that the audience can recognize and distinguish the brand from the others. At the end of the paper, we will offer some technical guidelines for Facebook, Instagram and Twitter posts. We will provide descriptions of each platform and examine some particularities in terms of image size.
