Frequently Asked Questions
What's the #1 highest-performing headline formula?
Social proof with numbers performs best at +48% average lift. "How [Number] [People] Use [X] to [Result]" combines specificity, credibility, and aspirational outcome. Example: "How 14,000 Teams Use This Framework to Ship 2x Faster."
Should headlines include numbers or words for quantities?
Use numerals (7), not words (seven). Numerals stand out visually in text and are processed faster. "7 Ways" outperforms "Seven Ways" by 23% in eye-tracking studies. Exception: numbers at the start of sentences in formal publications.
How long should headlines be for maximum conversions?
The ideal headline is 6-12 words or 50-70 characters. Headlines under 6 words lack enough information to create interest. Headlines over 12 words get truncated in search results and social shares. The sweet spot delivers complete value proposition without truncation.
Do negative headlines really outperform positive ones?
Yes, by 27% on average due to loss aversion. "Stop Making This Mistake" outperforms "Start Doing This Right" because humans are 2x more motivated to avoid losses than achieve gains. However, negative framing works better for problem-aware audiences. Test both.
How many headline variations should I test?
Test 2-4 variations per round. More than 4 variations dilutes traffic too much to reach statistical significance quickly. Start with your control vs one challenger. Winner becomes new control. Repeat. This sequential approach beats multivariate testing for most traffic levels.
What's the minimum traffic needed for valid headline tests?
You need 1,000+ visitors per variation minimum. At 5% conversion rate, that yields 50+ conversions per variation—still borderline. For reliable results (95% confidence), aim for 2,500+ visitors per variation. Lower traffic? Run tests longer (2-4 weeks) instead of shorter.
