Every page sent search engines the same empty 913-byte file

In short

The site only appeared after JavaScript ran. Without it, every address looked identical and blank.

What I did

I reviewed a product website built as a JavaScript app on a hosted site builder. Every address returned the same 913-byte HTML file with no text, no title and no links. The content only appeared after JavaScript ran in the browser. Even after it ran, no page had a title.
Where

A product distributor website, reviewed in October 2026
What changed

Nothing yet. During the review, a search for the brand's own domain did not show the site.
What you should do

Right-click your page and choose View Page Source. If you cannot see your main text there, search engines may not see it either. Ask your developer about server-side rendering.
How long it took

This is usually a rebuild, not a quick fix

Rendering is the step where the browser runs the page code to build what you see. Server-side rendering means the server sends the finished page, so the text is there from the start.

Why it matters

Google can run JavaScript, but it is slower and less reliable than reading plain HTML. Many other crawlers, including some AI tools, do not run it at all. For them, this site was empty.

How to check your own site

  • Press Ctrl+U on your homepage and look for your main heading and text.
  • Check the title tag in the source is not empty.
  • If the source is almost empty, the site depends on JavaScript to show anything.

What this changed in how I work

I look at the raw page source on every review, before any tool. A tool that runs JavaScript can hide this problem.
