I created an open source software which let you group/add all your socia media profiles and links into one link
Damn too bad you don’t have OG Tags. If you’re making a social app aggregator landing page then you should think about allowing users to add their own custom OG Title, OG Description and OG Image. But since you’re using Vue and Firebase you would need to SSR that with async data and set a Firebase Function to fire a URL that will build your site to include OG tags.
So after a few minutes the SEO value will be there, but the App will still work exactly like it does now, even before it’s built since OG Tags are invisible to the user when they’re on the site.
