Many blogshop owners start thir businesses with the mistaken assumption that their customers would make the same choices they would.
They choose their product offerings based on what they feel they themselves would purchase.This is flawed because ineivtably, the target market consists of “people much like themselves” which is usually a very narrow sub niche within a greater niche and is faddish by nature and prone to trends. Hence the need for research.
Don’t try to sell your customers on what you think they want. Instead, find out what they want and then make it easy and convenient for them to get that from you.
