Trying to market everywhere at once is how a lot of coaches end up marketing nowhere effectively, spread thin across platforms without doing any of them well.
Here are the four areas actually worth focused attention, and why depth in a couple of them beats a shallow presence everywhere.
Every other marketing effort eventually points here. If your public page is not clear about who you help and what you offer, everything upstream of it is wasted effort.
Consistent presence on a single platform where your ideal client actually spends time beats sporadic posting across four. Pick the one that fits how you like to create content, and show up on it reliably.
Happy clients rarely refer someone spontaneously, even when they would gladly do it if asked. Build a habit of asking at the right moment, rather than hoping word of mouth happens on its own.
A digital product or a referral incentive offered to current clients is often the cheapest marketing available to you, and it is the audience most likely to already trust you enough to say yes.
