Keep it simple. Someone landing on your site should be able to tell what you do, where you work and how to call you within a few seconds. Your history and the bigger story can go further down the page.
If you can, show some prices. Even a call-out fee or a “from” price for common jobs helps people trust you, and it filters out a lot of time-wasters.
Make it clear you're local. List the suburbs you cover and link your Google Business Profile. Most tradie work comes from searches like “plumber near me”, and that's how Google decides who to show.
Keep it up to date. A site that still mentions 2019 makes people wonder if you're still trading, which is why every site comes with a dashboard for changing your prices, photos and services yourself.
