Most SaaS products are built with modern JavaScript frameworks that create unique challenges for search engines:
JavaScript rendering issues (React/Next.js)
Client-side rendered content may not be visible to search engines. Even with Next.js SSR, improper configuration can cause entire sections to be invisible to Google.
Dynamic routes & crawl budget
SaaS apps generate thousands of dynamic URLs. Without proper canonicalization and crawl budget management, Googlebot wastes time on low-value pages.
App vs marketing site separation
Many SaaS companies mix their app and marketing site, causing authentication walls, noindex conflicts, and confusing signals to search engines.
Speed & Core Web Vitals
SaaS marketing sites often load heavy JavaScript bundles meant for the app. LCP, FID, and CLS issues directly impact rankings and user experience.

Common technical SEO mistakes in SaaS codebases
Deploying client-side only rendering for marketing pages
Next.js defaults to SSR/SSG, but lazy loading and dynamic imports can accidentally push critical content to client-side rendering.
Mixing app and marketing routes in one Next.js app
Authentication middleware can accidentally block Googlebot from crawling marketing pages if not configured properly.
Not handling trailing slashes consistently
Inconsistent trailing slash behavior creates duplicate content issues. Pick one convention and enforce it with middleware.
Ignoring image optimization
SaaS marketing sites often use unoptimized PNGs and JPGs. Next.js Image component + WebP conversion can cut page weight by 60-80%.

Why does technical SEO matter more for SaaS?
SaaS products are typically built with JavaScript frameworks (React, Next.js, Vue) that create rendering challenges for search engines. Dynamic routes, client-side rendering, and complex app architectures make technical SEO critical for discoverability.
Does Next.js handle SEO automatically?
Next.js provides great SEO foundations (SSR, SSG, metadata API), but you still need to configure it correctly. Common issues include improper dynamic route handling, missing canonical tags, unoptimized images, and poor Core Web Vitals. The framework helps, but it doesn't solve SEO on its own.
How often should technical SEO be audited?
For SaaS companies shipping frequently, we recommend a light audit monthly and a deep audit quarterly. Every deployment can introduce new technical SEO issues — broken routes, missing meta tags, or new JavaScript rendering problems.
