Mobile-First SEO 2026: Indexing, Performance & UX
Mobile-first indexing is the only indexing in 2026. Optimize tap targets, mobile INP, viewport, font scaling, and mobile-specific schema.
Mobile-first indexing in 2026
Google crawls and indexes the mobile version of your site, period. If your mobile experience is degraded, your rankings degrade.
The mobile audit
- Tap targets ≥ 48px with 8px spacing
- Mobile INP under 200ms
- No horizontal scroll
- Readable font (16px body, 1.5 line-height)
- Same content + structured data on mobile and desktop
- Same internal links on mobile
Mobile-specific wins
- Sticky CTAs that don't block content
- Tel/email/WhatsApp links with proper schemes
- Address with
geoschema for "near me" queries - Image dimensions to prevent CLS
Test on a real mid-tier Android phone. Throttled-CPU Lighthouse runs lie. Field data tells the truth.
