Six conversion design principles that hold up under pressure

Conversion design is full of folklore. Most of it is context-dependent and falls apart the moment you change the audience or the offer. These six have survived every project we've put them through.

One: clarity beats persuasion. A visitor who understands the offer converts more reliably than one who has been cleverly nudged but is still confused. Two: one primary action per screen. Competing calls to action split attention and lower the response to all of them.

Three: proof near the ask. Testimonials, results, and credibility markers belong next to the decision point, not buried on a separate page. Four: reduce the cost of saying yes. Shorter forms, clearer expectations, and a visible sense of what happens next all lower the perceived risk.

Five: speed is a feature. A fast site feels trustworthy and competent before a single word is read. Six: write like a person. Corporate hedging signals distance; direct language signals confidence. None of these are surprising. The discipline is in applying all six at once, every time.
