According to Wikipedia and numerous pundits and internet articles and lots of books on Amazon, the rule of three is a general writing principle that groups of three are generally more satisfying and easier to remember for readers or audience members. The same can be said of social media practices.
This principle is a lot simpler than it sounds – so don’t be scared off by it! Simply think of your posts as clusters of three. For one of the posts, you will promote yourself (things like your book, business, or brand). For another, you will promote someone else (things like their book, business, or brand). For the final post, you will post something unrelated to your book or business, but still connected to you and your brand (things like a hobby, vacation, family picture, etc.). Simply rotate through these three kinds of posts! It’s so simple, but it gives you a great starting place when it comes to knowing what kind of content to create. And we follow the rule . . . with three images below!
One more thing . . .
You don't have to do it alone! While it's important to make your voice and personality shine throughout your social media presences, you can get help. Take a tour through LinkedIn and search for virtual assistants. You can specify marketing assistants or social media assistants and hire someone to help build your brand, keep your sites fresh, and work with you on connecting to followers.
