Why this matters
Picking wrong does not cost you money, it costs you six months
The expensive part is not ad spend. It is the four to six months you burn applying for dealer accounts, waiting on approvals, uploading catalogs and getting ads live, before you work out the niche was never right for you.
At that point you are not pivoting. You are starting over, with a store branded for a niche you are walking away from.
This list will not pick for you. What it does is kill the blank page, which is the slowest part of starting. A thousand options you can work through beats ten you found on YouTube.
