Hi jacleaves!
Without your website URL it will be difficult to diagnose the problem as there are a few potential technical issues here. My main worries would be whether you're blocking indexation somehow and the fact you're displaying your content using JavaScript.
I'd start here:
- Check you're not blocking crawlers in your robots.txt file
- Check you're not using the noindex tag
I'd also try using fetch and render in Google Search Console (https://support.google.com/webmasters/answer/6066468?hl=en) for your site pages to see how Google sees them. If googlebot isn't seeing your content, that's a strong hint there's a JavaScript crawling problem.
Also, strap yourself in and read this - https://www.elephate.com/blog/ultimate-guide-javascript-seo/ - it's THE guide for JavaScript SEO.
Let us know how you get on and we'll go from there!
