What Is Mobile-Friendly (Responsive Design)?
A mobile-friendly website automatically resizes and reorganizes itself so it's easy to read and tap on a phone.
Most contractor traffic — often 70% or more — comes from phones. Someone's furnace just died, or their roof is leaking during a storm, and they're searching from bed or from the driveway. If your site looks broken on a phone, that customer calls the next contractor on the list.
Mobile-friendly (also called responsive) means the layout adapts: text stays readable without pinch-zooming, buttons are big enough to tap with a thumb, the phone number is a tappable link, and forms don't require sideways scrolling to fill out.
Google also uses mobile-friendliness as a ranking signal. A site that isn't mobile-friendly will lose search visibility on top of losing customers who bounce.
Real example
A roofer's site looked great on a desktop but on a phone the phone number appeared as tiny gray text and wasn't tappable. Homeowners had to memorize it, close the browser, open the phone app, and dial. Making the number a big tap-to-call button in the header added 20+ calls a month.
