A plumber with an empty diary needs enquiries quickly. A Checkatrade profile can put that plumber in front of people already looking for help. A website may take longer to bring enquiries, especially if it is new and hard to find on Google. This makes lead platforms useful when you need work now. They can help a new electrician, cleaner or dog groomer build a first set of jobs and reviews.
Your own website serves a different purpose. It gives people one place to check your services, photos, reviews, service area and contact details. It can help someone choose you after finding your name on a platform, in a van search or through a recommendation. The website also works outside one platform. For most trades, the sensible plan is to use both, then change the balance over time.
Think of a lead platform as rented space and your website as space you control. Rented space can bring visitors sooner, but the rules and costs belong to someone else. Your website needs more work at the start, but it can become a steady source of enquiries. The right mix depends on your trade, local competition, prices, availability and how well you follow up.
