Have you tried Facebook ads only to have your ad rejected because of the image? Or has your ad not converted in the way you had hoped? Typically the image you choose can be the culprit.
The good news is that you don’t have to be a graphic designer to create good images (although, of course, hiring a graphic designer is a great idea) but if you are on a tight budget, you can create something that will both convert and get approved.
Facebook Ad Sizes
The first step is to understand what ad image sizes work for each type of ad. The ad image sizes can change frequently. While there are many good “most recent ad size” charts out there, the best way to know for sure is to check with Facebook directly.
