Technical SEO Checklist 2026: Core Web Vitals, Crawlability & Indexing

Technical SEO is the foundation everything else sits on. If search engines cannot crawl, render, and index your site efficiently, even the best content will underperform. Work through this checklist.

Core Web Vitals

• LCP (loading): Aim for largest content to paint within 2.5s.
• INP (interactivity): Keep interaction latency low.
• CLS (stability): Prevent layout shifts as the page loads.

Mobile-First

Google indexes the mobile version of your site. Ensure responsive design, tap-friendly elements, and parity of content between mobile and desktop.

Crawlability & Indexing

• Keep a clean, accurate XML sitemap with lastmod dates.
• Use robots.txt to guide — not accidentally block — crawlers.
• Fix broken links and redirect chains.
• Set correct canonical tags to avoid duplicate content.
• Check Search Console for coverage/indexing errors.

Structured Data

Add schema.org markup (Article, Product, FAQ, LocalBusiness) so you qualify for rich results and give search engines clear context.

Site Speed & Security

Compress images, cache aggressively, use a CDN, and serve everything over HTTPS. Speed and security are both ranking signals and UX wins.
