Key Elements of SEO Website Design for 2025
1. Mobile-First Design: No Longer Optional
With mobile devices accounting for over 70% of web traffic in 2025, a mobile-first approach is absolutely critical. Google's mobile-first indexing means the mobile version of your site is now the primary version considered for ranking. To excel in mobile optimization:

2. Lightning-Fast Page Speed: The Need for Speed
In 2025, users expect near-instantaneous loading times, and search engines heavily favor fast-loading sites. To turbocharge your site speed:
