Is your website ready to do its job?
We run repeatable checks across the six basics: loading speed, findability, accessibility, trust, action and whether the copy sounds specific enough to believe. Every result also includes a separate AI visibility signal check.

Traceable
Each scan keeps the submitted URL, scan version, signals found and hashed IP. Raw IPs are not stored.
Action
Copy-paste
When an issue is specific enough, the report gives you a prompt to paste back into the builder and test again.
Index
72
373 scans run. Every completed scan is retained, versioned and rolled into the Clunky Index.
Re-scan wins
The useful bit is the before and after.
When a site is scanned again after changes, Clunky AI compares the two runs. We show anonymised positive lifts here, not client names or private URLs, unless someone chooses to share their own report.
Scan the site
The first scan creates the baseline score and shows the six basics that need attention.
Fix the obvious clunk
Use the evidence and fix prompts to make targeted changes rather than rebuilding the whole site.
Re-scan for the delta
A positive re-scan creates a shareable before-and-after result without exposing private report details.

Independent by design
Evidence first. No AI gloss.
Clunky AI checks the parts of a business website that decide whether it actually works: speed, findability, accessibility, trust, conversion and human-sounding content. The aim is simple: give founders and small teams a defensible score, the checks behind it and a short list of what to fix first.
What this AI website checker runs
We fetch and render the page, then check mobile speed, search signals, accessibility blockers, trust markers, calls to action, copy patterns and AI-search readiness.
What the free website health check gives you
You see the overall score and AI visibility check first. The emailed report adds the six-question breakdown, detailed evidence, PDF, badge and priority fixes.
What we keep
Each completed scan is stored with a hashed IP, scan version and raw signals. That is what powers the Clunky Index over time.
Only need to create or validate an llms.txt file?
Use the free generator and checker for an editable draft or deterministic file checks. llms.txt is optional and is not included in the Website Readiness Score.

A site can look tidy and still lose people because it loads slowly, hides the next step, misses labels or gives buyers too little reason to trust it.
The report is meant to be acted on.
Where the scan finds a clear issue, it explains the consequence and gives you the next fix to try. Re-scan afterwards to see whether the score moved.
