Ask HN: Is server side rendering necessary for good SEO of a React app on Google

[tylerwhipple]

In my company we are working to release a new version of our website which heavily uses React. For SEO reasons, we have been asked to create server side rendering. Historically, search engine crawlers do not support JavaScript. However, I have read a few blogs that hint Google renders javascript.

Is there any proof/does anyone have any experience with Google improved search rankings with server side rendering?

Googlebot renders the page properly but the indexing is complete garbage.

You need server side rendering. Learned this the hard way.
