The mobile-first SEO checklist that gets pages ranked in Google's mobile index — Core Web Vitals, schema, INP and AI search readiness.
Mobile-first is the only index that matters in 2026. Use this checklist on every page.
Performance: LCP < 2.5s, INP < 200ms, CLS < 0.1. Beat these on a mid-range Android, not on your MacBook.
Layout: single-column above the fold, tap targets ≥ 44px, no horizontal scroll, no intrusive interstitials.
Content: answer the query in the first 80 words. Use real H1, semantic H2/H3, descriptive alt text, internal links.
Schema: Organization sitewide, Service / Article / Product per template, FAQPage where genuine, BreadcrumbList on deep routes.
AI surfaces: add original data points and direct-answer paragraphs — that's what gets cited.
