Reverse proxies give you SEO credit but they come with considerations:
✅ SSL/TLS – You need valid certificates for your domain.
✅ Canonical tags – Ensure they point to blog.example.com, not the SaaS domain.
✅ Performance – Proxying adds latency; use caching (Nginx cache, Cloudflare).
✅ Terms of Service – Some SaaS providers forbid proxying.
✅ Broken assets – Images or scripts may use absolute URLs; you may need to proxy those too.
