Most visits start on a phone, in a driveway, the morning after a hailstorm
Design for a small screen, a distracted reader and a connection that is not what your office has.
The desktop mockup is not the real page. The real page is six inches tall, held at arm's length, in bright sun, competing with a neighbor who is also having a conversation about roofs.
Whoever built the site probably reviewed it on a fast connection over office wifi. Test it instead on a phone with the cache cleared, on cellular, in a neighborhood at the edge of your service area. What loads first tells you what you actually built.
The top of the page needs three things and nothing else. Who you are, where you work, and how to start. Everything decorative can wait until the reader has decided you are worth scrolling for.
Tap targets and phone links matter more than they should have to. A phone number that is an image, or a call button too close to a menu item, silently costs jobs and never shows up in any report.
