Key focus areas in frontend optimization

This guide breaks down practical improvements across core areas of modern web development.

  1. Performance

    Measure speed, spot bottlenecks, and use CDNs, optimized images, non-blocking scripts, and caching for a smoother experience.

  2. Mobile-first design

    Ensure a seamless experience on every device by starting with mobile layouts, scaling up for larger screens, and keeping CSS easy to maintain.

  3. Technical SEO

    Boost search visibility with mobile-first indexing, structured HTML, optimized images, hreflang tags, and breadcrumb navigation.

  4. Accessibility

    Follow WCAG 2.1 AA standards, apply semantic markup, and design for inclusivity—ensuring your site works for all users.

  5. Maintainable frontend code

    Use patterns that keep code lean, reusable, scalable, and compatible across browsers without adding complexity.
