The "so what?" test
Read your headline aloud. Add "so what?" after it. If you can answer convincingly, the headline works. If you can't, it's vague. "AI-powered analytics platform" — so what? Nothing. "See what's driving revenue and what isn't" — that answers it. The test catches almost every weak headline because vague headlines fail the question by definition.
Five formulas that consistently score
(1) Outcome + audience: "Help [audience] [achieve outcome]". (2) Before/after: "From [pain state] to [goal state]." (3) Specificity: "[Number]+ [audience] use [product] to [outcome]." (4) Question: "What if [audience] could [outcome] without [pain]?" (5) Anti-promise: "The only [category] that [unique mechanism]." Pages we analyze using one of these formulas score 14 points higher on the First Impression dimension than headlines that don't.
What to avoid
Generic verbs (empower, transform, revolutionize), category-only labels (CRM platform, marketing tool), feature lists (AI-powered, cloud-native, enterprise-ready), and clever wordplay that requires a second read. Run your headline through the analyzer to see whether it passes the 5-second test before you ship it.
