What are some simple ways to improve the layout and presentation of a local service website?

I’m working on a local service website and trying to make the overall layout cleaner and easier to navigate. What are some simple design improvements that can make a handyman or home-service website look more professional?

I’m mainly thinking about things like page structure, service sections, mobile responsiveness, colors, and making it easy for visitors to find the information they need. I came across this handyman website while looking at examples: https://www.thehandybrosco.com/

What other things would you recommend checking before considering the website design finished?
