SSR vs. dynamic rendering: render-budget cost compared

SSR vs. dynamic rendering: render-budget cost compared

Across 74 JS-heavy domains, time-to-indexed for net-new pages split hard by rendering strategy.

— Server-side rendered: median 2.1 days to index ▓▓░░░░░░░░
— Dynamic rendering (bot-only SSR): median 4.8 days ▓▓▓▓▓░░░░░
— Client-side only: median 9.6 days, p90 22+ ▓▓▓▓▓▓▓▓▓▓

Dynamic rendering also showed a 6.1% rate of bot/user content mismatch flagged in spot audits.

So what: dynamic rendering was a 2019 bridge, not a destination. It halves CSR's indexing lag but carries cloaking-adjacent risk and infra you maintain twice. If you're rebuilding anyway, SSR/SSG beats it on every axis. Keep dynamic rendering only for legacy stacks where SSR is genuinely blocked — and audit the bot-vs-user diff quarterly.
