Each secondary category is another set of searches your profile can appear in. They don't dilute your primary — they extend it. And most businesses either leave the section empty or never look at what's in there.

A salon owner I worked with added "Nail salon" and "Eyebrow threading" as secondaries after our audit. Her profile impressions picked up noticeably within the first month. She hadn't changed anything else.

Go to Edit Profile → Business Category and look at what's listed below your primary. If the section is empty or thin, you're leaving searches on the table.

Think about your secondary services: the things you actually offer beyond your core business. Add the category that matches each one. Then stop. Don't add categories for things you don't do. Google is better at detecting category mismatch than it used to be, and irrelevant categories can pull you down in the searches that matter most.

Only mark what's real. A customer who shows up expecting a service you listed but don't offer will say so in a review.

Which secondaries did you add? Hit reply and let me know.

Next week: the description field. Most are either blank, or say something Google quietly ignores.
