At least through 2022, video adverting opportunities will abound on Facebook, Instagram and other social networks, new research suggests.

Brands will get better engagement if they have fans looking forward to the next piece of content. The more content you produce, the more engagement data you get back, which you can tailor to users' wants and needs.
