JavaScript-heavy marketing sites fail SEO when rendering, caching, and internal linking are afterthoughts. Your first diagnostic is parity: compare rendered HTML vs raw response for money templates.
For most SaaS marketing stacks, SSR or SSG for indexable routes is still the safest default. Client-only rendering should be reserved for authenticated or low-value experiences.
Watch Core Web Vitals at the template level, not site-wide averages. Hero images, third-party scripts, and font loading often tank LCP on product pages while blogs look fine.
After migrations, monitor indexed URL counts, redirect chains, and ranking volatility for 90 days. Most losses are recoverable if caught early.
