Content Without JavaScript
Most AI crawlers read your raw HTML — many do not execute JavaScript at all. SaaSalyst measures how much of your visible text survives with JavaScript off, because a page that renders client-side only can read as nearly empty to the systems deciding whether to cite you.
What SaaSalyst Checks
SaaSalyst compares the visible text extractable from your server-delivered HTML against a minimum-content threshold. A page whose meaningful copy only appears after client-side rendering warns here; a page whose core copy ships in the initial HTML passes.
Why This Matters
Server-rendered or statically-generated marketing pages are readable by every crawler tier — cheap HTTP fetchers included. A client-rendered SPA storefront is readable only by crawlers that run a browser, which is the expensive path many AI retrieval systems skip.
This is a structural signal: fixing it usually means changing how the marketing site renders (SSR, SSG, or prerendering), not editing a file. SaaSalyst classifies it as a traction-side signal and weighs it at low severity while it is warn-only.
How to Fix It
- Serve your marketing pages server-rendered or statically generated (Next.js, Astro, plain HTML) even if the app behind login stays a SPA.
- If a rebuild is not practical, add prerendering for the marketing routes so crawlers receive populated HTML.
- Verify with: curl -s https://yoursite.com | grep -i 'your headline' — your core copy should be present.
Frequently Asked Questions
Do AI crawlers execute JavaScript?
Mostly no. SaaSalyst's check assumes the conservative case: assistants' fetchers read served HTML, and only some search-engine pipelines render JavaScript. If your copy needs a browser to exist, you are betting your discoverability on the most expensive crawler path.
My app is a SPA — is that a problem?
Not behind login. SaaSalyst only measures the public marketing surface; the fix is rendering THOSE pages on the server or at build time, which most frameworks support without touching the product itself.
