The AIDA framework is a classic copywriting structure: Attention, Interest, Desire, Action. Attention hooks the reader, Interest deepens engagement, Desire builds emotional pull toward the offer, and Action closes with a clear next step.
AIDA is over a century old and still holds up because it maps to how humans process persuasive content. Modern copywriters use it as a diagnostic more than a rigid template: if a piece is failing, check which of the four stages is weak.
