A service page should explain who the work is for, the problem it addresses, the deliverables and how an engagement begins. Use the language your customers use when describing their problem.
Give each distinct service its own useful page. Add descriptive titles, internal links and clear contact options. For bilingual websites, provide complete language versions and matching language alternatives.
After launch, use Search Console to review indexing and the searches that bring visitors. Improve pages using those findings and the questions you hear in sales calls. Search visibility grows through useful content, sound technical foundations and ongoing work.
