Facebook Text Overlay Tool
The Facebook team, during their early days in digital advertising, were able to observe that many of its users were bothered, or ignored, by advertising containing a high level of text in the images, and determined that users perceived a lower percentage of the text in seconds. Facebook created a system to assess text quality in images that would run as ads. The Text Overlay tool performs a pre-image review and evaluates how acceptable the image is to the audience at different levels. With this new process, images that exceed 20% text in the ad reject them. This text verification process is used for both Facebook, Instagram, and Audience Network advertising (only Instagram Stories does not yet have the requirement to have a text limit). The text level in the image may not show or be penalized in the auction and maintain a smaller scope compared to an image containing 20% text.
