SPA and SEO are not compatible. SPA is good for apps, backends, admins ...

A SPA supporting deep linking and an access model that provides unauthenticated access to public content should, in principle, be able to be made indistinguishable from a set of classic webpages with the public portion of the app content, from an SEO perspective, at least if one takes the JS rendering ability of the search bot(s) of concern into account.
