Try AI BobThe offer is good, the page is clear, and conversion is still flat.
Clarity is not persuasion. A visitor who understands your offer perfectly can still fail to act, because acting requires certainty that copy alone does not supply. The seven principles describe where that certainty comes from, and where to place it on the page.

Most campaigns spend everything on the message and nothing on the moment before it. The research covers both.
01
What a reader is thinking about in the second before your message arrives changes how they read it. Pre-Suasion is the study of that second, and it is the one most campaigns spend nothing on.
02
Visitors who follow your argument perfectly still fail to convert, because understanding is not certainty. Social Proof, Scarcity and Commitment supply the certainty, and they work best placed at the point of hesitation.
03
In a category where everyone claims the same things, claims stop counting. Authority and Liking are what a reader weighs instead, and both can be earned honestly.
The POP Workshop is two days of hands-on work at round tables. Participants work through each principle together and practise it on situations from their own work.
