How to Use This Tool
- Type or paste a headline. The score updates live as you type — no need to click anything. Examples to try: a blog title (12 Tested Strategies to Lift Conversion by 40%), an email subject (Re: your roadmap question), an ad headline (Cut payroll-processing time by 40% — try free), a landing-page H1 (The fastest path from idea to revenue). Or click Blog Sample, Email Sample, or Landing-Page Sample to see well-tested patterns.
- Read the 0−100 score and verdict. Scores above 80 are headlines worth shipping. 60−79 are solid candidates for A/B testing. 40−59 need a rewrite. Below 40 should be discarded. The verdict line explains the score in one sentence so you don't have to interpret the number.
- Inspect the word-balance breakdown. Four cards show how many words fall into each category: Power (purple, attention-grabbing), Emotional (pink, response-triggering), Uncommon (green, concrete and specific), Common (gray, function words). Healthy headlines have 1−3 power words, 0−2 emotional words, and a mix of uncommon and common. All-common signals boring; all-power signals clickbait.
- Check the length and Flesch grade. Word count of 6−12 is the sweet spot; below 5 feels incomplete; above 13 loses scanners. Character count matters for the surface — SEO titles cap at ~60, mobile email subjects ~40. Flesch grade is the implied reading level (8th grade or lower is ideal for most marketing copy; 12+ feels academic and reduces engagement).
- Read the suggestions panel. 1−5 targeted tips based on what's missing or excessive: "Add a power word", "Shorten to 6-12 words", "Try a specific number", "Lower the reading grade", "Reduce all-caps words", etc. Each suggestion is rooted in the score weights, so applying it moves the score up measurably. Positive feedback confirms what's already working.
- Compare variants when you have multiple candidates. Switch to Compare mode, paste 3 different versions of the same headline (benefit-led, curiosity-led, urgency-led for example), and click Compare. Side-by-side scores with the winner badged. Use the winner as your A/B test contender, or iterate further if no variant cracks 80.
About Headline Analysis
Headlines are the single highest-leverage piece of copy you write. A blog post gets 5× more visitors with a great headline than a mediocre one; an email gets 2−4× the open rate; a Google Ads RSA can lift CTR 30−100% from headline alone. Despite this, most teams treat headlines as something you "scrape together" in the last 5 minutes after the body is finished. This tool inverts that order: write 3−5 candidate headlines first, score them, iterate the top 2 against each other, and only THEN write the body. The math says you'll ship more impact for the same hour of work.
What the score actually measures. The 0−100 score combines five signals weighted by empirical effect on CTR across consumer and B2B contexts: (1) Word count — 6−12 word sweet spot, with penalties for <5 (incomplete-feeling) or >15 (lost scanner). (2) Power words — presence of 1−3 of the ~200 vocabulary items that consistently trigger above-baseline response (urgency, exclusivity, value, credibility, curiosity, intensity); penalty for 0 or 5+ (clickbait threshold). (3) Emotional words — presence of 1−2 of the ~300 emotion-vocabulary items; bonus is smaller than power words because the effect is more audience-dependent. (4) Specificity — numbers, concrete nouns, and uncommon words score positively; all-common-words headlines feel generic and are penalised. (5) Readability — Flesch grade level ≤8 is rewarded, >14 penalised. (6) Sentiment — positive or negative beats neutral, but the bonus is small.
Power words explained. The 200+ power-word library divides into six families: Urgency (now, today, instant, last chance, limited), Exclusivity (secret, hidden, exclusive, members-only), Value (free, save, bonus, half-price), Credibility (proven, certified, guaranteed, award-winning), Curiosity (discover, revealed, why, how, secret), and Intensity (amazing, jaw-dropping, mind-blowing, ultimate). These words work because they activate emotional shortcuts the human brain processes faster than neutral language. Use 1−2 per headline, not more. Above 30% density triggers clickbait detection in Google's ML quality classifier and Meta's ad-delivery filters, which suppresses your impressions. Always pair a power word with a concrete benefit ("Save $200 on Plan Pro" beats "Save money").
Emotional words vs power words — the difference matters. Power words drive immediate response (click, scroll, buy now). Emotional words build connection (love, fear, joy, anger, hope, surprise). A good headline blends both: emotional vocabulary establishes affinity, power vocabulary closes the click. Examples: "The secret [power] our customers love [emotional] about Plan Pro"; "Hidden [power] reason your team feels burned out [emotional]". Headlines using only power words feel mechanical; headlines using only emotional words feel vague. The tool tracks both separately so you can adjust the mix.
Length sweet spots by surface. Word count matters less than character count for most surfaces — here's a quick reference: Google SERP title 50−60 chars (truncates around 580px in Arial 20px); blog H1 6−12 words / 50−80 chars; ad headline (Google RSA) 30 chars; ad headline (Meta) 40 chars; email subject 40−50 chars on mobile (iPhone truncates around 40 in portrait); LinkedIn headline 70 chars. This tool reports word count and character count; cross-reference against the surface where the headline will live. Going over the surface limit means truncation in feed, which destroys read-through — even if the content past the cutoff is gold.
Compelling vs clickbait. Mechanically they look similar — both use power words, curiosity hooks, emotional triggers. The difference is in the read-through: compelling headlines deliver on the promise (low bounce, high time-on-page); clickbait does not (high bounce, low time-on-page, eventual brand-level CTR decay as Google rewards user-satisfaction signals). Tactical signs you're crossing into clickbait: vagueness ("You won't believe what happened"), absolute language without basis ("The ONE trick"), hyperbole ("shocking", "mind-blowing") applied to routine content. Stay compelling: the headline should accurately preview the content, even if you use power words to dress it up. This tool can't tell intent — it just scores word balance — so use the suggestions panel as guidance, not gospel.
SEO title vs article title vs social card — three different surfaces. Treating them the same is one of the most common mistakes in content marketing. SEO title (the <title> tag, what shows in Google SERP) optimizes for search behaviour: short (50−60 chars), keyword in the first 30 chars, clear benefit, brand at the end. Article title (the H1) optimizes for reader behaviour after the click: more wordsy, more personality, more emotional pull. Social card (og:title) optimizes for scroll-stopping in feed: emotional, conversational, no brand. Tools like Yoast and RankMath let you set these independently. This tool scores any of the three — just paste each variant separately. Most successful blogs run 3 different headlines for the same article across the 3 surfaces.
At EmproIT, our Content Marketing team writes high-converting headlines, email subjects, and ad copy across all surfaces — backed by audience research, in-channel A/B testing, and a brand-voice library that compounds organisational knowledge over time. Pair this tool with the A/B Test Calculator to plan headline experiments, the Readability Checker to verify the body matches the headline's reading level, and the SERP Snippet Previewer to see exactly how the SEO title renders in Google.
Frequently Asked Questions
What makes a great headline?
Four ingredients in different ratios: specificity (numbers, concrete nouns, named entities), emotional pull (power and emotional words triggering response), clarity (topic understood in under 2 seconds), and implied benefit (answers "what's in it for me" before they finish reading). Strong headlines hit 3 of 4. Weak headlines hit 1 (usually clarity alone). Avoid clickbait — extreme emotional pull with zero benefit erodes trust. This tool scores headlines against a balance of all four dimensions.
What is the ideal headline length?
6−12 words is the sweet spot for most contexts. Below 5 words feels incomplete or lacks specificity. Above 13 words readers' eyes glaze. Character limits by surface: Google SERP title 50−60 (truncates ~580px Arial 20px); H1 in long-form 60−80 chars; email subject 40−50 mobile-safe (iPhone Mail cuts ~40 in portrait); Facebook ad 40 chars; LinkedIn 70 chars. This tool flags <5 or >13 word count and shows character count for cross-reference.
What are power words?
Vocabulary items that consistently trigger above-baseline response. Categories: urgency (now, today, instant), exclusivity (secret, hidden, members-only), value (free, save, bonus, half-price), credibility (proven, certified, guaranteed), curiosity (discover, revealed, why), and intensity (amazing, jaw-dropping, ultimate). Use 1−2 per headline, not more — density above 30% triggers clickbait detection in Google's ML quality classifier and Meta's ad-delivery filters, depressing impressions. Always pair with a concrete benefit ("Save $200 on Plan Pro" beats "Save money").
Emotional vs logical headlines — which is better?
Depends on audience and funnel stage. Emotional headlines outperform for consumer products and top-of-funnel social where decisions are feeling-driven. Logical headlines outperform for B2B, professional services, and bottom-of-funnel decision-content where buyers evaluate ROI, fit, and risk. Top-of-funnel: lead with curiosity, surprise, identity-affirming phrasing. Mid-funnel: balance benefit and proof. Bottom-of-funnel: lead with specifics, credibility, risk-reduction. This tool flags zero-emotional or zero-specific headlines as risk — balance both.
Should I use numbers in headlines?
Yes — specific numbers lift CTR consistently across blog, ad, email, and SERP surfaces. Numbers signal scannability ("I know how long this will take") and concreteness. Odd numbers (7, 9, 11) slightly outperform even in some studies. Specific numbers (Save $237.50 a month) outperform round (Save $250). But don't fake-specific — 237.5% claims need a source. Avoid number stuffing ("7 best 10x tactics from 5 founders to get 3x results"); one number per headline is optimal. This tool rewards headlines containing a digit (small +5−8 bonus).
What's the difference between clickbait and compelling headlines?
Compelling headlines make a promise the content delivers; clickbait makes a promise the content does not. Mechanically similar — both use power words, curiosity hooks, emotional triggers. The difference shows in read-through: compelling has low bounce + high time-on-page; clickbait has high bounce + low time-on-page. Long-term clickbait consequences: brand-level CTR decays (Google rewards user-satisfaction signals); unsubscribe rate spikes; social shares become hostile. Clues you're crossing: vagueness ("You won't believe"), absolute language without basis ("The ONE trick"), hyperbole on routine content, removing the benefit from the title entirely.
How do you A/B test headlines effectively?
Discipline: write 3−5 variants using distinct strategies (one benefit-focused, one curiosity, one number-led, one social-proof, one urgency); pick a primary metric (CTR for awareness, conversion rate for performance); use the sister A/B Test Calculator to compute required sample size. Most platforms support headline testing: Google Ads RSAs auto-rotate; Meta Ads Manager has A/B Test framework; for blog posts use a CMS plugin (RankMath, Yoast). Run minimum 7 days to capture cycle variance. Don't peek — peeking inflates false-positive rates 5% → 14%+. Document winners over a year to build organisational memory.
SEO title vs article title — should they be the same?
No, and treating them the same is a common SEO mistake. SEO title (the <title> tag, shows in Google SERP): short (50−60 chars), keyword in first 30 chars, clear benefit, brand at the end. Article title (the H1, shows on page): more wordsy, more personality, more emotional pull. Example: SEO title "Best Ad Copy Generator — Free Online Tool | EmproIT"; H1 "Stop staring at a blank ad copy template — this generator builds 6 variants in 30 seconds". Tools like Yoast and RankMath let you set them independently. Social cards (og:title) often follow a third pattern. Match the headline to the surface, never copy-paste the same line everywhere.
