Restaurants, bars, coffee and takeout. Menu on a phone, hours that are true tonight, whether there is a dock, and photos of the actual room. The guest is choosing between you and two other tabs in the time it takes the kids to put shoes on.
Salons, spas, massage and anything a wedding party books. Group bookings, availability by date, what a bridal party costs, and a form that actually delivers. If the site cannot answer that in writing, the maid of honour books somewhere that can.
Boat, pontoon and watercraft rental, service and storage. Rates by the day, what is in the fleet, and a number that gets answered on a Saturday morning in June. A page per thing you rent, because that is what people search for.
Vacation rentals and the smaller resorts. You are not competing with the big resort on amenities, so do not try to on the website. Compete on being easy: a page per unit, rates on the page, which lake and how far to the courses, and an enquiry form that works in February. Resort and rental sites goes deeper.
Dock and lift, roofing, plowing, property checks and the trades. The owner is in the Cities. A page per service with Pelican Lake and Breezy Point in plain text is how you get found by someone who has never been to your shop and never will.
