Technical SEO Checklist: Optimizing Modern Web Apps for Google Search
By Editorial Team•
Why Technical SEO Is More Critical Than Ever
Search engines reward speed, accessibility, and structured data clarity. A modern web app built on frameworks like Next.js must adhere to rigorous technical guidelines to maximize crawl budget and secure Google Rich Results.
1. Core Web Vitals (CWV)
- Largest Contentful Paint (LCP): Keep hero image assets optimized with modern formats (WebP, AVIF) and preload high-priority banners. Target under 2.5 seconds.
- Interaction to Next Paint (INP): Eliminate long tasks and excessive JavaScript main-thread blocking.
- Cumulative Layout Shift (CLS): Reserve layout dimensions for all media and banners to avoid visual jumping.
2. Structured Data (JSON-LD)
Schema markup bridges the semantic gap between raw HTML and Google's knowledge graph.
- Implement `BlogPosting` or `Article` schema on editorial content.
- Implement `JobPosting` schema with accurate salary, employment type, and validThrough attributes on listings.
- Validate your JSON-LD syntax regularly with the Google Rich Results test.
3. Canonical Architecture & Sitemap Freshness
- Enforce strict self-referential canonical URLs across all pages to prevent duplicate indexation.
- Automate sitemap pinging via Google Indexing API and IndexNow (Bing, Yandex) upon publication or deletion.
