Rendering & Indexing Engineering

Solving Googlebot’s Two-Wave Indexing

Google defers client-side JS rendering. If your HTML payload lacks content or links, Googlebot leaves before rendering occurs.

Blank HTML Payloads

Client-Side Rendered (CSR) apps send `

` with empty body text. Googlebot cannot extract keywords or links on initial crawl.

Hydration Errors & Execution Timeouts

Heavy JS bundles and unhandled console exceptions cause Googlebot's Web Rendering Service (WRS) to abort execution before content loads.

Uncrawlable Single Page Navigation

Using `div onClick` handlers instead of standard `` anchor tags prevents search crawlers from discovering deep application routes.

JS SEO FAQs

Javascript SEO Questions & Answers

Everything you need to know about rendering JS applications for search.

Can Googlebot render React and Next.js applications?

Yes, Googlebot can execute JavaScript, but it relies on a two-wave indexing process. If rendering takes too long or encounters API errors, Googlebot skips execution, resulting in missing indexation. Server-Side Rendering (SSR) or Static Site Generation (SSG) ensures instant indexation.

What is the difference between CSR, SSR, and SSG?

Client-Side Rendering (CSR) builds HTML in the user's browser (slowest for SEO). Server-Side Rendering (SSR) generates full HTML on every server request (great for dynamic content). Static Site Generation (SSG) pre-renders HTML files at build time (fastest for SEO and speed).

Why are my Single Page Application (SPA) links not getting indexed?

If your SPA routes rely solely on JavaScript event listeners (`onClick`) or hash URLs (`/#/product`), Googlebot cannot follow them. Links must use standard `` tags with proper server routing.

What is Dynamic Rendering and when should it be used?

Dynamic Rendering serves pre-rendered static HTML to web crawlers (like Googlebot) while serving standard client-side JS to human visitors. It is an effective solution for legacy JS apps that cannot easily migrate to Next.js or SSR.
