You should come up with a campaign based on what it is that you wish to accomplish through your videos. If you want to sell a certain product, your campaign should target the different parts of your audience in a way that they are likely to respond to. Sometimes, if your product is meant for more than a single demographic, you may have to come up with multiple marketing videos, each directed towards a specific subset of your audience.
These videos help to build trust because they allow people to experience the intimate side of your brand, and they make people associate your brand with transparency. Behind the scenes videos tend to perform very well on social media, and they are therefore highly effective as marketing tools.
Apart from creating an emotional connection with prospective customers, behind the scenes social media videos tend to express the true personality of your company. They capture its unique culture, and they give it a human face so that people no longer think of it as a soulless corporation, but as a collection of hardworking and creative people with values that are similar to theirs.
