The honest floor is not a dollar figure, it is a data figure. You need enough clicks each month to tell the difference between a good week and a bad one.
Work backwards from a click
Find the cost per click for your main service, then aim for sixty to a hundred clicks a month. In most Twin Cities service markets that lands somewhere between a few hundred and a couple of thousand dollars.
Below that, every decision is a guess dressed up as optimization. Above it, patterns become visible within a few weeks.
Spend it narrow before you spend it wide
One service, one geography, one offer will teach you more than the same budget spread across everything you sell. Once that combination is profitable, widen it.
What to have ready before the first pound goes out
A page that matches the ad, conversion tracking that fires, and somebody who answers inquiries the same day. Ads magnify whatever is already there, including the gaps.
See Google Ads management for how the account gets structured, and landing page design for where the clicks should land.
