Images and Videos inspire the most engagement on Facebook.
We live in a visually oriented world, and images capture attention and inspire engagement actions including “Like”, “Share”, and “Comment” more than other text-only methods.
Facebook, in its own research, found that the most successful posts for capturing the attention of users and inspiring action are visual. Photo albums generated 180 percent more engagement than other types of posts, and individual photos 120 percent more. Since 40 percent of a Facebook user’s time is spent in the News feed, capturing attention to inspire a “Like,” comment or share by using images is critical.
An important part of posting correctly also includes using a mobile friendly Smart URL. See how to get one here: Mobile Smart URL Guide for Facebook Pages
