SEO begins before design
Search visibility is not a handful of keywords added after a page is finished. Site architecture, user intent and content scope should be defined before design begins.
Understand search intent
You cannot build the right page without knowing the question a user wants answered. Every important service needs a clear purpose and its own page.
Keep a logical heading hierarchy
Use one descriptive H1 per page and H2/H3 headings that divide the subject clearly. Headings should not be selected only for visual effect.
Performance and mobile usability
Oversized images, unnecessary code and excessive motion slow the experience. Performance and accessibility are design decisions.
Publish useful content
Content should answer real questions, use practical examples and stay up to date.
