CRO Analysis
CRO Analysis assesses how well a page converts, built on measured data: the page's actual HTML is fetched, and Lighthouse runs for both mobile and desktop via Google's PageSpeed API. The AI then evaluates only the measured facts and proposes improvements.
The tool is uncompromising about labeling: every single number in the report carries either a green "Measured" badge (from the page or Lighthouse) or an "AI assessment" badge. You always see what is fact and what is interpretation, and the report states explicitly what was not measured.
Who it's for
Anyone who wants to know why a page underdelivers on conversion and wants to prioritize fixes by impact versus effort, with numbers they can verify.
Prerequisites
- Freelancer plan or higher
- 15 credits per analysis
- A publicly reachable URL
Step by step
- Paste the URL.
- Optionally describe the conversion goal ("book a demo", "complete purchase"); the analysis then prioritizes toward it.
- Run. HTML fetch, two Lighthouse runs and the assessment typically take half a minute or more.
Reading the results
- The source overview at the top shows which data sources actually succeeded; a failed source is shown honestly rather than hidden.
- The Core Web Vitals panels (LCP, CLS, TBT) are drawn against Google's published thresholds for mobile and desktop; red there is measured reality, not opinion.
- Form friction and trust signals are counted from the page's HTML: number of fields, required fields, fields without labels, and which trust elements exist or are missing.
- The impact/effort matrix is where to start: the quick-wins corner gives the most for the least.
- The finding cards show which measured number each finding rests on, plus a hypothesis and how to measure the effect of the fix.
- If you see a client-rendered-page warning, null values mean "not measurable from HTML", not "missing".
Common problems
- The analysis fails: all failures are refunded automatically, including when the page didn't respond or the assessment couldn't complete.
- In your credit history the charge is named "cro-analyze"; that's this tool.
Limitations
- Pages over 5 MB of HTML are rejected.
- The analysis looks at one URL at a time; run the landing page and the confirmation page separately.
- Results are not saved; copy what you want to keep.
