How to Use CV A/B Testing

Instead of guessing which version is stronger, put them side by side. The tool analyses two versions of your CV and measures four things: word count, action-verb density, presence of numeric results, and keyword coverage — then shows you the gap between them.

The steps

1. Paste the first version on the left and the second on the right
2. Run the comparison and read each version's score
3. Note which measures improved and which regressed
4. Take the winner of each measure and merge them into one version
5. Re-test the merged version to confirm it holds both advantages

Practical tips

• Compare two versions aimed at the same job; comparing across different roles tells you nothing
• Change one variable at a time so you know which edit produced the difference
• Run it right before you apply to pick the final version

Common mistakes to avoid

• Choosing on gut feel when the numbers say otherwise
• Comparing a very long version against a very short one, which only judges length

Frequently asked questions

How is this different from the score checker?

The score checker evaluates completeness through a checklist. A/B testing actually analyses your text and compares two versions on specific measures.

Are the versions I paste stored?

No. The analysis runs in your browser on the text you paste; nothing is saved or sent.
