A service website should help users and search engines understand what the company does within the first screen. The page needs a unique H1, clear service copy, internal links, contact actions, and proof blocks.
The safest starting point is a small content map: homepage, service index, individual service pages, portfolio, pricing approach, blog, contact, and policy pages. Each page should have a canonical URL and a clear next action.
Internal links matter because they connect commercial pages with supporting articles and portfolio examples. A blog post can link to a service page, a service page can link to pricing, and a portfolio page can link back to a relevant service.
