For infographic writing, brevity is the key. According to a study by Microsoft, the typical internet user has an attention span of around 8 seconds. Try to keep your infographic writing short and concise, while using imagery to tell the majority of the story. The human brain can process images fast - sometimes as fast as 13 milliseconds. In addition to imagery, try to bypass the gab by making your content funny or relatable. Funny stuff tends to be more memorable and increases engagement. That’s all. Like I said, keep it brief!
