Free JavaScript content check
Is your page readable before JavaScript runs?
Many crawlers read the HTML a server sends and do not run JavaScript. If your words only appear after scripts run, those crawlers receive an almost empty page. This check counts what arrives first. Free, no signup, about a minute.
Confirming you are a person
Cloudflare runs this before each check. If a box appears, tick it. The card closes by itself.
What this check reads
The visible words in the HTML your server sends, before any JavaScript runs: what a crawler that does not render receives.
- Pass: 150 or more visible words arrive in the initial HTML.
- Mixed: between 40 and 149.
- Fail: fewer than 40.
Why it matters
Google renders JavaScript, though later and not always. Many of the crawlers that fetch pages for AI answers read the raw HTML only. A page that builds itself in the browser can look complete to a visitor and empty to them.
What it cannot tell you
A one-page check cannot tell a page whose content loads afterwards from a page that is simply short. It reads the page you enter, not the rest of the site.
If it fails: the repair, step by step · Making the page worth quoting
The answer leads; the full result follows
This page runs the whole EdenLens free check and puts the answer to its own question first. Underneath you get the rest of the result: up to three verified problems across the page, each with its repair.
Example results
- Wraycroft Creamery, before the repairs: three verified problems
- Wraycroft Creamery, after the repairs: no repair findings
- Eden Valley Joinery: insecure connection, blocked AI crawlers, opening hours missing
- Kinetiq Studio: content that only appears after JavaScript runs
All four are invented businesses. Each page is the engine's own output, published so it can be read without running a check.
The other free tools
Each one runs the same check and leads with its own question.
- The full free audit: up to three verified problems across all of it
- AI crawler access: can ChatGPT, Claude and Perplexity fetch the site?
- Business identity: can a machine tell who the business is?
- Sitemap: does a sitemap list the pages worth finding?
- Readable content: is the page readable before JavaScript runs?
What to do next
The paid reviews add wider investigation, human judgement and accountable advice. What this check could not assess is not a failure, and the free repairs stay free.
