Modern JS frameworks boost UX but confuse crawlers. Learn why rendering delays and hidden DOM elements impact your site’s indexability.
Client-side rendering slows indexing as bots see empty pages first. Server-side rendering (SSR) ensures crawlers access full HTML instantly.
Hydration mismatches break structured data and links. Use React hydration fixes or Next.js streaming to keep SEO signals stable and visible.
Heavy JS scripts exhaust Googlebot’s crawl budget. Minify, lazy-load non-critical scripts, and avoid multi-step rendering to reduce queue delays.
Pre-render tools like Rendertron or Prerender.io create static HTML snapshots for bots, ensuring full crawlability without harming UX.
JS bloat increases LCP and CLS. Split code, defer scripts, and monitor with Lighthouse to improve Web Vitals and overall SEO trust.
