SSR doesn't fix a blurry architecture. If an app still reads content from hardcoded HTML or depends on window and localStorage without protection, the problem doesn't disappear by rendering on the server.
First the foundation
Before SSR, it's worth closing four things:
- content resolvable by slug,
- metadata per page,
- coherent canonicals,
- browser-safe code.
Then SSR
When the information is already modeled, SSR multiplies value. Before that, it only complicates the diagnosis.
The question isn't whether SSR is worth it. The question is whether the app already has a content layer that makes it worthwhile.
