The 10 usability heuristics, rewritten as a conversion checklist
· 9 min read
Heuristic evaluation is the fastest credible way to find usability problems without a research budget. The trick is translating each principle into a question about revenue.
Status, language and control
The first three heuristics decide whether a user feels oriented. If they cannot tell what is happening, what things are called, or how to get out, they will not commit to a transaction.
- Visibility of system status: does every action produce visible feedback within 400ms?
- Match with the real world: does your microcopy use your customer's words, not your internal ones?
- User control and freedom: can someone undo, go back or exit without penalty at every step?
Consistency, prevention and recognition
The middle heuristics decide whether the interface is learnable. Inconsistent patterns force re-learning on every page, and re-learning is friction users pay for with attention they do not have.
- Consistency and standards: is the primary action the same colour, shape and position sitewide?
- Error prevention: are you validating inline before submission rather than punishing after?
- Recognition over recall: is critical information visible when needed, not remembered from earlier?
Efficiency, aesthetics, recovery and help
The final four decide whether the experience scales from a first-time visitor to a repeat customer.
- Flexibility and efficiency: are there shortcuts for returning users — saved details, quick reorder?
- Aesthetic and minimalist design: does every element on the page earn its place?
- Error recovery: do error messages say what went wrong and exactly how to fix it, in plain language?
- Help and documentation: is contextual help available at the moment of doubt, not buried in a FAQ?
