For Google, using React-Helmet for SEO works okayish with just React I believe. If I search for “makermove” I do see my project MakerMove turn up with the different routes that it has. But for social sharing on Twitter or Facebook, it’s not really suitable if you want to share a specific route and show the social image etc. Also directly entering a route does not work, although the pre-render option on Netlify is doing a very nice job with that! You could just simply check a box.
