Long-form copy isn't inherently better than short-form — the right length depends on the price point, complexity, and familiarity of the offer, not a fixed rule.
Higher-Priced, More Complex Offers Usually Need More Length
A significant purchase decision typically requires more education, proof, and objection handling than a short page can provide.
Simple, Low-Commitment Offers Can Convert With Less
A low-priced or low-risk offer often doesn't need extensive persuasion to overcome, so a shorter letter can perform just as well as a long one.
