An ideal customer persona is the target customer for your product.
It spells out who your customer is, what they do and their demographics. It paints a picture of who they are.
It dives into what problems they have, their hopes and aspirations.
And most importantly - a persona ties your product into how it solves their problems.
Crafting a customer persona makes it easier to build content buckets.
It makes it easier to know their pain points, which in turn makes it easier to sell your product.
Without knowing your customer, you are selling to everyone.
And selling to everyone means your selling to no one.
