"You'll see less public content like posts from businesses, brands, and media" - Mark (Facebook CEO)
This leads to you having to do 1 of 2 things if you're looking to stay ahead of your competitors.
Leverage a user-generated content marketing strategy. (A UGC strategy is fueled by customers and since the new update is focused on showing you more content from friends and family. Then getting your customers to make posts about your product will lead to you having a higher chance of getting results.)
Pay-to-play. (Since social engagement and reach is declining using Facebook ads will help make sure you are getting optimal results.)
With images being the second most shared type of content you should definitely be posting images to gain awareness about your brand.
It's also important to note that if you are going to post make sure you are giving value rather than trying to promote your own product or service.
Otherwise, if you only promote yourself then you will not receive a good amount of engagement or shares.
5. Businesses are planning to use stories more often.
Social media stories are a way to share a behind the scenes of the business. Typically stories are almost always shot at the moment and are not the typically high-quality content you would find on your feed.
Stories are a very easy way to make a quick post with little to no effort and still get you a good amount of engagement.
