Real Time Online Engagement
Face it, real time online engagement takes up a lot of time. You may not have the time to do it yourself. The social media agency you hire may only allocate a few minutes for real time engaging. The social media person you hire may create great graphics and posts but they'll schedule them like they do for all their other clients and may only have a few minutes to actively engage online with your brand.
Basically, you're only paying these people to have a beautiful online presence that's alive.
Honestly, who would you rather spend one year of your life with? A beautiful human that only says things at certain times of the day or someone that offers thoughtful conversation?
