Your Category Is Your Destiny
If there's one field in your Google Business Profile that matters more than any other, it's your primary category.
It's the #1 ranking factor for the local pack.
Get it right and you're in the game. Get it wrong and no amount of reviews or backlinks will save you.

Google has over 4,000 categories to choose from. Find the one that matches your core service most precisely. Good keyword research will tell you what your customers actually search for — start there.
