As someone who started out as a social media manager, moved up into higher-level content marketing strategy, AND hired SM help in the past... I have PLENTY of experience in this arena.
1. Bravo for understanding the importance of strategy before creation & distribution. So many business owners want to delegate their SM work to a cheap assistant before actually putting a plan in place. It never works out in their favor.
2. Do you have an established brand identity, voice, and core message in place? What about an ideal client persona? The more in depth you are with these guidelines, the easier it will be stay on track with your content topics & goals.
3. How will your social media content feed into your overall sales funnel? Most people will say that Instagram and Facebook are top of the funnel initiatives, but I close the majority of my sales on social media so that's something to keep in mind.
4. How lucrative are each of those platforms for your business? Maybe you need to cut it down to 2 or 3 social media platforms and really hone in on those audiences. Less is more in some (actually, most) cases.
It's really all about narrowing down your options and zeroing in on what WORKS FOR YOU. There's no one-size-fits-all marketing plan.
If you'd like to book a call, I'd love to discuss the possibilities for your social media marketing strategy. Hope this helps!
