SEO & React

Please have in mind these are field notes organized in a common structure that I use for myself or for my students, university classes and industrial activities. They may be messy, with errors and in some cases, without proper references. If you find your work (or part of it) here without proper acknowledgement, please let me know so I can fix it as soon as possible.

!GoogleBot vs Caffeine

That is why websites built on React (and other JavaScript platforms) perform worse in Google than websites that primarily serve plain HTML to the crawler.

The best solution is to opt for Server Side Rendering (SSR) or Server Side Generation (SSG) mainly due to:

  • Faster initial renders.
  • Not having to rely on search engine crawlers to render content.
  • Improvements in TTI due to less JavaScript code for the browser to parse and render before becoming interactive. Source
