- Humans read faster than we speak. So when you have short attention spans and a news feed type setup it's important to ensure that the videos have captions so that you can grab attention as soon as possible. --- Facebook marks the caption option as recommended for a reason: it works. If people have turned the sound off on their phone, they’ll still be able to see your message. As soon as they see the text, they’ll start to read it. It pulls them in and draws their attention. We can read faster than we speak so when you’ve got just a few seconds to grab someone and stop them scrolling, that text will help to get your message across much faster than waiting for someone to finish speaking. You’ll be able to prove that you’ve got something they should see before their thumb starts to move. - Perry Marshall in [[Ultimate Guide to Facebook Advertising]]
