This is the most important step, it’s what set’s up your ground game if you will.

Keyword research is the same thing, unless you know what people are searching for, you’re writing content in the dark and hoping it’ll reach it’s audience.
Please, whatever you do don’t trust Google Keyword Research tool for this either. Besides not giving you sources & volume, they suggest things that are relevant for their PAID ad program. Which of course they want to sell you more of, so they are NOT going to give you the data you need.
