Videos are the thing right now (they have been for a while) and likely will continue to be so. For business pages, making the Facebook cover picture a video is easy.
Uploading a video as your Facebook cover image is as simple as uploading a new photo. Hover your mouse over the cover image on your Facebook page and you’ll see a camera icon pop up. Click the Change Cover icon. You can choose a video as your cover image the same way you’d add a new cover photo. Depending on your niche or industry, or niche in your industry, you can change up your cover photo or video quite often. I would caution you to not stray from your look.
So, no matter what the video is, there should be some sort of visual and audio cue that it is yours. A feel that stays with each video. Whatever your message is and whoever your target market/audience is, you are still creating content directed at them.
