Optimizing for mobile SEO

Most web traffic now comes from mobile devices. A mobile-optimized site provides a better user experience, improves search rankings, and increases engagement.

Why Mobile Optimization Matters

• Mobile-first indexing: Google uses the mobile version of your site for indexing and ranking.

• Majority of users on mobile: Over 63% of organic searches occur on mobile devices.

• Bounce rates: Slow or poorly designed mobile experiences drive visitors away quickly.

Key Mobile SEO Strategies

• Build your site with a responsive framework so it adapts to all screen sizes and devices.

• Avoid separate mobile subdomains (like m.example.com); a single URL supports better crawling and sharing.
