Will pre-rendering an SPA improve my SEO?
Hello!
I run an SPA selling digital products. Our meta and hreflangs are dynamically injected via JavaScript. Some pages are indexed correctly, but we’ve noticed errors in Google Search Console and in the Google results, like no canonical selected (although it’s in the page source) and a wrong title (using the index.html title, not the JavaScript-rendered title).
I suspect there’s some delay in JavaScript loading and sometimes the crawler doesn’t get the JavaScript content. We are considering pre-rendering the pages with Puppeteer and serving it to crawlers. According to Google’s webmaster guidelines, it’s not cloaking if the content is nearly the same. And I have seen posts from technologies that are capable of pre-rendering that SEO gets a huge improvement after that.
Any experiences or insights on this?Thanks!

Yeah – we much prefer Server-Side Rendering when possible (dynamic rendering just for Google is ok, but the documentation has been updated to say this is a workaround), but we find that full SPA’s will eventually get indexed, but it’s not as fast or consistent. You can make it work – but it’s easy to start with a static copy for crawlers.
