About the handbook

A practical reference for understanding purchase decisions and improving the pages that support them.

Conversion Handbook is an English-language publication for founders, product teams, growth practitioners, and designers. Our focus is commercial: the landing page that gets attention but little action, the pricing page that makes choosing harder, the form that asks too much, and the experiment that needs a clearer question.

What you’ll find here

Our articles examine the decisions behind commercial pages, with practical examples and links to the research. We cover buyer research, commercial pages and forms, and conversion experimentation across SaaS, consumer products, and ecommerce.

Examples explain a way of working. They are not promises of a particular conversion lift. Synthetic data and illustrative interfaces are labeled so readers can separate a teaching example from an observed result.
