Headlines that stop the scroll, copy that converts, CTAs that force action.
Research-first; the headline is 80% of the ad. Lead with data, never adjectives. Prices always visible. A/B test the appeal and measure cost per message — not CTR. FR + AR/Darija variants, WhatsApp CTA beats 'Learn More' 3:1.
Each term links to the live lexicon — definition, case study, origin, related terms.
