Should I set up a Google Business Profile if I don't have a storefront?

Yes, and it's free. If you work out of a truck instead of a storefront, you set it up as a service-area business: no address shown, and you list the towns or counties you actually work. That's the normal, supported way for a mowing route or a hauler to be on the map — you're not bending a rule.

What matters after that is boringly consistent: the same business name, phone number and service area everywhere they appear — your profile, your site, your invoices, the truck. Don't stuff keywords into the name field; profiles get suspended for that, and rebuilding one is a miserable month. Put real photos of real work up, and ask happy customers for a review the day you finish, not a week later.

It's also the cheapest proof that you exist. A stranger who's just been let down by somebody else searches at 9pm, and the outfit with photos, hours and a phone number that answers gets the call.

A profile works best pointed at something real — a site with your name on it, a booking page, a number that rings. That's the part we build.
