Not every page should be rendered the same way. A marketing landing page, a logged-in dashboard, and a frequently-updated product catalog have completely different needs. Choosing the right rendering strategy is one of the highest-leverage architecture decisions you'll make — it affects load speed, SEO, infrastructure cost, and developer experience all at once. And the good news is that modern frameworks let you mix strategies per route, so you don't have to pick just one.
The options, briefly
There are four approaches worth knowing, and most real apps use a combination:
- Static generation (SSG) — pages are rendered to HTML at build time and served as files. Fast, cheap, and cacheable, but the content is fixed until the next build.
- Server-side rendering (SSR) — HTML is rendered on the server for each request. Always fresh, great for SEO, but every request does work.
- Client-side rendering (CSR) — the server sends a near-empty shell and JavaScript builds the page in the browser. Flexible and app-like, but slower to first paint and harder for crawlers.
- Hybrid and streaming — render a fast static or server shell, then hydrate or stream in the dynamic parts. This is where most high-quality sites land today.
What each is good (and bad) at
The trade-offs cluster around three concerns:
SEO and crawlability. Search engines and AI crawlers work best with content that's present in the initial HTML. SSG and SSR deliver that directly. Pure CSR can be indexed, but you're relying on the crawler to execute JavaScript correctly and patiently — a risk you don't need to take for content that matters to discovery.
Time to first byte vs. interactivity. SSG has the fastest time to first byte because it's just serving a file. SSR is slightly slower because it renders per request, but still delivers meaningful content immediately. CSR ships fast bytes but a blank screen — the user waits for JavaScript before seeing anything useful.
Caching and cost at scale. Static files are trivially cacheable on a CDN and cost almost nothing to serve. SSR can be cached too, but uncached requests consume server resources, so cost scales with traffic. CSR offloads rendering to the user's device, which is cheap for you but pushes the work (and the wait) onto them.
A page-by-page decision guide
Rather than choosing one strategy for the whole app, match the approach to each page's job:
- Marketing and content pages (home, blog, landing, docs) — these need to load fast and rank well, and the content changes infrequently. Use static generation or server rendering with aggressive edge caching.
- Authenticated app views (dashboards, settings, account areas) — these are personalized, behind a login, and don't need SEO. Client rendering (often behind a server-rendered shell) is a fine fit, since speed-to-content matters less than rich interactivity.
- Frequently changing public data (product catalogs, listings, prices) — these need freshness and SEO. Server rendering with short cache lifetimes, or static generation with incremental revalidation, gives you both.
The question to ask for each page: Who needs to see this, how fresh must it be, and does a search engine need to read it? The answers point straight to the right strategy.
Why we default to SSR plus edge caching for marketing sites
For most marketing and content sites, our default is server-side rendering deployed to the edge, with caching tuned per route. It's a deliberate balance:
- Content is in the initial HTML, so search engines and AI crawlers see everything without executing JavaScript.
- Edge caching means most visitors get a cached response served physically close to them — nearly as fast as static, with far more flexibility.
- Dynamic routes (a contact form, a personalized block) can still render fresh when they need to, without rebuilding the whole site.
- A single rendering model is simpler to reason about than stitching static and client rendering together by hand.
This is the approach behind this very site: server-rendered, edge-cached, with content present in the HTML so it's fast for people and legible to crawlers.
Avoid the common traps
Two mistakes show up repeatedly:
- Defaulting to a single-page app for everything. CSR is the right tool for rich, authenticated interfaces, but reaching for it on a content site sacrifices SEO and first-paint speed for no real benefit.
- Over-engineering with mixed strategies too early. You don't need four rendering modes on day one. Start with the simplest model that meets your SEO and freshness needs, and add complexity only where a specific page demands it.
The best rendering strategy is the simplest one that loads fast, stays fresh enough, and lets the right audience — human or crawler — see your content.
