How to use the Headline Analyzer

Type or paste your headline

Enter the headline candidate — blog title, article title, newsletter subject line, ad headline. Tool scores in real-time. Test multiple variants quickly by editing in place.

Read the 0-100 score

The score weights four factors: length (8-14 words ideal), power words (1-3 emotional/curiosity/practical words boost CTR), numbers (listicles + specifics outperform vague language), and uncommon ratio (40-70% non-common words signals specificity). Above 80 = excellent; 60-80 = strong; 40-60 = decent; below 40 = needs work.

Iterate based on the advisory

The advisory text tells you EXACTLY what to fix: too short, missing power words, no numbers, too generic. Make one change at a time and watch the score update live. Three-to-five iterations usually take a 30/100 generic headline to 70/100+.

Test 5 headline variants

Don\'t go with your first idea. Write 5-10 headline candidates; score each; pick the top 2-3 for A/B testing in production. Live testing (Google Analytics, Facebook Ads, email subject A/B) is the only true CTR measure — this tool predicts likely performance, not guaranteed performance.

Headlines — the single highest-leverage line you'll write

The headline does most of the work in content marketing. David Ogilvy famously said "On average, five times as many people read the headline as the body copy." Translation: if your headline doesn\'t earn the click, your 2,000-word article doesn\'t exist. CoSchedule, BuzzSumo, and other content-analytics platforms have studied millions of headlines and consistently find the same factors predict click-through: specific length (8-14 words), power-word density (1-3 per headline), numbers/specificity, and a careful balance of common vs uncommon words. This tool applies the same heuristics in real time so you can iterate before publishing.

The four ingredients of a high-CTR headline

(1) Length: 8-14 words consistently outperforms shorter or longer in CTR studies. Short headlines lack specificity ("SEO Tips"); long headlines drag ("The Complete Guide to All the SEO Strategies You Could Possibly Need in 2025 Edition"). Sweet spot: enough to specify the topic + benefit + audience. (2) Power words: emotional ("amazing", "shocking"), practical ("free", "essential", "proven"), curiosity ("secret", "hidden", "surprising"), and urgency ("now", "today") drive 10-30% CTR lifts. Use 1-3 — more reads spammy. (3) Numbers: listicles ("7 ways") and specific numbers ("271 free tools") outperform vague language by 15-30%. Numbers signal specificity + tangible promise. (4) Uncommon ratio: too many common words ("the", "is", "of", "and") makes headlines feel generic; too many uncommon words makes them feel like jargon. Sweet spot: 40-70% uncommon words.

"On average, five times as many people read the headline as the body copy. When you have written your headline, you have spent eighty cents out of your dollar." — David Ogilvy

Headline templates that consistently work

Five evergreen headline structures with strong CTR track records. (1) Listicle: "N [Adjective] [Topic] [Verb] [Benefit]" — e.g., "7 Underrated SEO Tools That Beat the Paid Ones". (2) How-To: "How to [Achieve Outcome] [Without Pain Point]" — e.g., "How to Rank on Google Without Backlinks". (3) Curiosity: "[What/Why/The Real Reason] [Subject] [Surprising Outcome]" — e.g., "Why Most Marathon Runners Slow Down at Mile 18". (4) Benefit-led: "[Get/Save/Cut] [Specific Outcome] in [Time]" — e.g., "Cut Your Email Time 40% in One Week". (5) Question: "Is [Common Belief] [Wrong/Right]?" — e.g., "Is Long-Form Content Actually Better for SEO?". Pick the template that fits your content type; modify variables; score; iterate.

The ASEAN content market headline reality

Headline performance varies meaningfully across ASEAN audiences. English-second-language: most ASEAN ex-Singapore reads English as L2. Clever wordplay, double meanings, and idioms underperform — they require cultural fluency. Direct, concrete benefit-led headlines outperform across the region. Localised power words: "Singapore", "Malaysia", "Philippines", "ringgit", "lah" boost CTR 10-20% on region-specific content. Don\'t over-localise though — if the content is region-agnostic, the locality reference feels gimmicky. Native-language headlines: when writing in Bahasa Indonesia/Malaysia, Thai, Vietnamese, or Filipino, this tool\'s English power-word list won\'t apply directly. Translate the structural principles (length, specificity, numbers, curiosity), not the literal words. Mobile-heavy reading: ASEAN traffic is 70-85% mobile; mobile SERP + social headlines truncate earlier than desktop. Front-load the hook in the first 8 words.

10 Things to Know About Headlines

David Ogilvy: "5× more people read the headline than the body." 80 cents of your dollar lives in the headline.

8-14 words consistently outperforms shorter/longer. Short = generic; long = drag.

Power words boost CTR 10-30%. Limit to 1-3 — more reads spammy.

Numbers in headlines boost CTR 15-30%. "7 ways", "271 free tools", "5 surprising facts" — specificity wins.

Listicles ("N things") still dominate the top 10 content formats by CTR. Odd numbers (7, 9, 11) slightly outperform even.

"How to" headlines have above-average CTR because they signal a specific actionable outcome.

Question headlines ("Is X wrong?") boost engagement when the question is genuinely uncertain — feels like the article will resolve it.

Headlines that begin with how, why, what outperform statement headlines on average.

Negative headlines ("Don\'t do X", "Why X is wrong") often outperform positive — loss aversion is stronger than gain attraction.

L2 English audiences in ASEAN respond better to concrete benefit-led headlines than clever wordplay. Skip the puns.

Frequently Asked Questions

The 0-100 score is a weighted composite of four factors: length (up to 30 points for 8-14 words / 40-65 chars), power words (up to 25 points for 2-4 in the curated lists), numbers (up to 15 points for any numeric digit), uncommon ratio (up to 20 points for 40-70% non-common words). Bonus points for question headlines + W-word starters (how/why/what). Heuristic, not magic — backed by widely-cited CTR studies but always confirm with live A/B testing.
Similar approach, different implementation. CoSchedule\'s analyzer uses similar heuristics (length, power words, sentiment, common-uncommon ratio) plus their proprietary models. This tool uses an open implementation of well-known heuristics without the proprietary scoring layer. Use both as second opinions; trust live A/B test data over any algorithmic score.
No. The score predicts AVERAGE CTR based on heuristic patterns. Audience-specific resonance, topic relevance, and context still dominate. A 90/100 headline about an irrelevant topic still won\'t convert; a 50/100 headline about a deeply resonant topic can outperform. The score is one signal among many. Use it to avoid OBVIOUSLY weak headlines; rely on A/B testing for confidence.
1-3 per headline, yes. Beyond 3, power words read spammy ("Amazing! Incredible! Shocking! Unbelievable! Secret!"). The right power word adds specificity + emotional weight: "free" signals value, "proven" signals credibility, "secret" signals exclusivity, "underrated" signals contrarian opportunity. Pick words that fit the content; don\'t shoehorn them in.
All three work; the best fit depends on content type. Listicles: best for survey/roundup content ("7 SEO tools to try"). How-to: best for tutorial/instructional ("How to set up Google Search Console"). Question: best for myth-busting or contested topics ("Is fasted cardio actually better?"). Listicles consistently get the highest open rates; how-to gets the highest engagement on the body; question gets the most comment + share activity.
Mostly yes, with caveats. Email subject lines reward shorter length (5-9 words) than blog headlines (8-14). Power words for email skew toward urgency ("today", "expires") + curiosity ("what nobody tells you") more than emotional/practical. Spam-trigger words to avoid: "free!!!", "guaranteed", "act now", excessive punctuation, all caps. The 30-50 char length sweet spot for email subjects renders fully on mobile inbox previews.
Often better than positive. Loss aversion is psychologically stronger than gain attraction — "Why Your SEO Strategy is Failing" outperforms "How to Improve Your SEO Strategy" in many tests. Controversial headlines (taking a clear stance against conventional wisdom) drive comments + shares but can polarise. Caveat: clickbait that doesn\'t deliver on the headline harms trust + bounce rate. Negative headlines + strong delivery = great combination. Negative headlines + weak content = brand damage.
Yes — A/B testing is the only real measure of headline performance. Use Facebook Ads A/B (cheapest), Google Optimize (now sunset; alternatives: VWO, Optimizely), or email subject line A/B (built into most email platforms). Test ONE variable at a time (different power word, different number, different structure). Run until statistical significance (typically 2-5K impressions per variant). Combine the algorithmic score with live testing — score for shortlist, A/B for winner.
No. All analysis runs in your browser via JavaScript. Open DevTools → Network and confirm zero outbound requests. Headline text + scores stay on your device. Safe for unpublished drafts, confidential campaign planning, or competitive headline research.
