What is mobile optimization?
SEO Definition and Examples
Mobile optimization is adapting a site for mobile. Google ranks "mobile-first" — pages not optimized for mobile rank poorly.
Full Definition: What is mobile optimization
Mobile optimization refers to adapting a site for mobile devices (phones, tablets). Components: (1) Responsive design (adapts to any resolution); (2) Large fonts (at least 16px for readability); (3) Easy-to-tap links (44x44px padding); (4) A configured viewport meta tag; (5) No Flash (deprecated, incompatible with mobile); (6) Optimized mobile loading speed. Google moved to "mobile-first indexing": Google crawls and ranks based on the mobile version, not the desktop one. A page not optimized for mobile ranks poorly even if the desktop is perfect. Testing: Google Mobile-Friendly Test.
Why Does Mobile Optimization Matter for SEO?
Over 60% of organic traffic comes from mobile (and growing). Pages not optimized for mobile = you lose 60% of your potential audience and rank poorly.
