The Myth

"Google can't properly index JavaScript-rendered content."

The Truth

Google CAN render and index JavaScript content. Since 2019, Google uses an evergreen Chromium renderer. However, there are caveats: JS rendering is resource-intensive and may be delayed (second wave of indexing), complex SPAs may have issues, and other search engines handle JS poorly. Server-side rendering or hybrid approaches are still recommended for critical content.

Insight from @dejanseo

"Google handles JavaScript, but it's not instant. Critical content should be server-rendered if possible. Don't block Googlebot from JS resources, and test what they actually see."
