The parts
Every page has the same job
Somebody found you on their phone and has about ten seconds to decide whether to call. Everything on the page exists to answer one of the four questions they're actually asking.
Are you the right place?
Your name, what you do, and where you are, big enough to read at arm's length. No slideshow, no stock photo of somebody else's shop.
Are you any good?
Your Google rating and review count, pulled from your real listing. Not testimonials I wrote for you.
Are you open?
Your actual hours, not a guess. This is the detail people check most and the one most small sites get wrong or leave stale.
How do I reach you?
Your phone number as a button that dials when tapped, a map of your corner, and a form that lands in your inbox.
Photography
Your photos beat stock, always
I won't put a stock photo of some other salon on your page. Customers can tell, and it undercuts the one thing the page is claiming. Three phone photos of your actual shop are worth more than anything I could buy, and taking them costs you ten minutes.
