Technical SEO for Client-Side Rendered Apps
A developer and SEO engineering resource focused on making JavaScript-heavy applications crawlable, indexable, and performant in search. From Googlebot rendering queues to framework-specific hydration fixes — everything you need to make your CSR app rank.
Rendering Intelligence
Understand exactly how Googlebot processes JavaScript — two-wave indexing, WRS execution limits, and why your CSR app might be serving blank pages to crawlers.
Metadata That Sticks
Master dynamic title tags, Open Graph injection, JSON-LD lifecycle management, and canonical URL strategies that survive client-side hydration.
Framework-Specific Fixes
Copy-paste implementation patterns for React Router, Vue Router, Angular Universal, and SvelteKit — tested against real crawler behaviour.
