A service website should answer five questions quickly: what you do, who it is for, where you serve, why the visitor should trust you and what they should do next. If any of these are unclear on mobile, traffic will be wasted. Use one clear primary action per page, keep contact options visible, reduce unnecessary form fields and place proof close to the decision point. Pages should load quickly, use readable typography and avoid intrusive elements that block the main content. For SEO, each page needs a distinct purpose, descriptive title, useful main heading, canonical URL and contextual internal links. For measurement, track calls, forms, messages and other meaningful conversion events rather than pageviews alone.
