Client-side rendering silently destroys organic traffic. We've found the same Next.js SEO problems across dozens of SaaS audits — and we know how to fix them fast.
These are the exact issues we find repeatedly when auditing Next.js and React SaaS sites.
When a Next.js page uses browser-only APIs (window, localStorage, document), it forces a full CSR bailout — overriding SSR. Google crawls an empty shell. This is one of the most silent and damaging SEO bugs in Next.js apps.
CriticalPure Create React App (CRA) or Vite SPAs have no server-side rendering at all. Googlebot fetches the page and gets <div id="root"></div> — literally nothing. Your product, features, pricing, and blog are all invisible without JS execution.
CriticalSchema added via useEffect() or componentDidMount() is invisible to Googlebot in the first crawl wave. Competitors with server-rendered schema get FAQ rich results, breadcrumb trails, and star ratings. You get plain blue links.
HighIn CSR apps, canonical and meta tags are set via document.head manipulation after JS runs. But Googlebot's first-wave crawl reads only raw HTML. Result: no canonical signal, potential duplicate content issues, and ranking dilution across URL variants.
HighSocial crawlers (Facebook, LinkedIn, Twitter) don't execute JavaScript at all. If your OG tags are set by React Helmet or client-side code, every social share shows a blank preview card. This kills referral traffic and brand credibility.
HighDynamic routes in Next.js (/product/[slug]) require getStaticPaths for static generation. Without it, those URLs either return 404, redirect to an error page, or serve empty HTML shells. Your sitemap says you have 200 pages; Google can only index 10.

We don't just run a Lighthouse scan. We crawl your site the way Googlebot does — raw HTTP, no JavaScript.
We fetch every page exactly as Googlebot's first-wave crawler sees it — no JavaScript execution. We document what's missing.
We identify whether you're running SSR, SSG, CSR, ISR, or a mix — and flag every page that falls back to client-side rendering unintentionally.
We check canonical tags, OG tags, schema markup, and H1 tags in the raw HTML response. If it's only in JS, it doesn't count.
You get a ranked list of issues by SEO impact — what to fix first, exact code changes needed, and expected ranking improvement per fix.
Traditional SEO agencies run surface-level tools. We crawl like Google and fix what actually matters.
