Research the demand for information
See what are the top questions they search on Google about your niche, and prepare videos answering those questions.

Prepare a script so you don't go off the deep end
The good thing, if brief, is twice as good. Try to adapt the length of the video to the main social network.

Configure your technical equipment
The camera, microphone and lighting are the three elements where you should invest some money to get a more professional result.

Edit your video with rhythm
The rhythm should not only be in your feet. It is also important that your piece does not have a monotonous and boring tone, but a dynamic and daring one.

Schedule the day and time
Use the same video (or different versions of it) and schedule its publication on different days and times, depending on each social network.
