Why does my React site score low on SEOSync?

SEOSync (like most crawlers and many AI fetchers) reads the raw HTML response. If your copy only appears after JavaScript runs, the audit sees an empty shell even though Chrome looks full.

Not always. Prerender critical pages, put key copy and FAQ in the static HTML shell, or use SSR/SSG for money pages. The goal is crawlable text and schema in the first HTML response.

How do I check what bots see?

View page source (not Inspect), or curl the URL, or run a free SEOSync audit. If source has almost no H1 or body text, bots and AI engines see the same problem.

Why AI bots see an empty React page (and your browser does not)

Client side React apps often look fine in Chrome but return a nearly empty HTML shell to crawlers and AI fetchers. How to spot the gap and fix crawlable content.

Your React app can look rich in the browser and still look empty to Googlebot style crawlers and many AI fetchers. The difference is JavaScript: browsers execute it; many audits and answer engine crawls only read the first HTML response.

What crawlers actually fetch

A typical Create React App or SPA shell is title tags, a root div, and a script bundle. Your H1, pricing copy, and FAQs appear only after React mounts. SEOSync scores that shell, which is why AEO can stay low after you "fixed" the UI.

How to spot the gap

View Page Source and search for your H1 text
curl the URL and check word count in the HTML

Fixes that work for SaaS marketing sites

Put a crawlable summary, definition, and FAQ in static HTML for home and pricing
Prerender or SSG money pages (Next.js, Astro, Webflow export, or similar)
Keep FAQPage JSON LD in the initial head, not only after hydration

Ship static content, audit the same URL again, and compare SEO and AEO before/after.
