What a headline checker measures

A headline checker evaluates a title against a set of measurable criteria that correlate with click-through rate. The basic version returns a single overall score. The useful version breaks the score into dimensions so you can see which part of the headline needs work.

This tool measures five dimensions.

Clarity. Can a reader parse the headline in under three seconds. Ambiguity, jargon, and nested clauses lower clarity. Simple subject-verb-object structure raises it.

Emotion. Does the headline trigger curiosity, urgency, authority, aspiration, fear, or humor. Neutral headlines score low. Headlines with clear emotional leaning score high.

SEO. Does the headline include the target keyword, and does the keyword appear early enough to survive truncation in search results. Keyword-stuffed headlines score lower than keyword-first headlines.

Length. Does the headline fit the platform. A 90-character headline works on LinkedIn but gets truncated on Twitter, Google SERP, and email subject lines. Platform context determines the ideal range.

Power words. Does the headline include high-performing trigger words like "proven," "secret," "fast," or "you". Power words lift CTR but overuse triggers spam filters and reader skepticism. One or two per headline is optimal.

Each dimension gets a score from 0 to 100. The tool shows all five scores side by side so you can identify the weakest link. A headline that scores 95 on clarity but 30 on emotion is clear but boring. A headline that scores 90 on emotion but 40 on length gets cut in the SERP.

The fixed version rewrites the headline to address the lowest-scoring dimensions while preserving the core idea. Changes appear as tracked edits so you can accept, reject, or adapt them.

How to use this headline checker

  1. Paste Your headline into the input. Maximum 150 characters.
  2. Set Platform. Choose blog post, Twitter, LinkedIn, Google Ad headline, email subject, or YouTube title. Each platform has different character limits and user expectations. Scoring adjusts to match.
  3. Optional: paste up to two more headlines into Compare with. The tool scores all three side by side so you can pick the strongest.
  4. Hit Analyze headline. You get five dimension scores, a composite score, platform-specific warnings, and a rewritten version with fixes highlighted.

Try this input: headline "Tips for Better Productivity," platform "blog post." The output might show clarity 80, emotion 35, SEO 40 (no keyword), length 85, power words 20. The fixed version might read "7 Productivity Hacks That Save You 10 Hours a Week" with changes highlighted: added number, replaced vague "tips" with specific "hacks," inserted time-saving claim for emotional hook, added measurable outcome.

Why per-platform scoring matters

A headline optimized for one platform underperforms on another. Google rewards clarity and keyword placement. Twitter rewards curiosity gaps and brevity. LinkedIn rewards authority and specificity. Email subject lines reward personalization and urgency. YouTube titles reward clickbait within reason.

Backlinko analyzed 5 million Google search results and found that titles with the target keyword in the first half of the headline correlated with higher rankings. That pattern does not hold on Twitter, where burying the hook until the end can increase retweets. Buzzsumo analyzed 100 million Facebook headlines and found that question-format headlines outperformed declarative headlines by 14% on engagement. The opposite is true on LinkedIn, where declarative authority statements win.

Three practical consequences.

CTR varies by platform. A headline scoring 85 overall might score 95 on LinkedIn and 60 on Twitter because LinkedIn users expect longer, more formal titles. Without platform context, the score misleads.

Character limits are hard constraints. Google truncates SERP titles at roughly 60 characters or 600 pixels. Twitter truncates at 280 characters but users see only the first 70 in the feed preview. Email clients truncate subject lines at 40 to 50 characters on mobile. A headline that fits one platform gets cut on two others.

Tone expectations differ. Humor works on Twitter. It fails on Google Ads. Authority works in B2B LinkedIn posts. It reads as stiff on Instagram. The same headline cannot serve every platform. The checker adjusts tone scoring based on where you plan to use it.

Platform scoring is not optional. It is the only way to know whether a headline fits the context where it will appear.

The five dimensions explained

Clarity (0-100). Measures how quickly a reader can parse the meaning. Short sentences, common words, and active voice raise clarity. Long sentences, jargon, passive voice, and ambiguity lower it. Example: "Leveraging Synergistic Approaches to Optimize Outcomes" scores 20. "How We Cut Costs by 30%" scores 95.

Emotion (0-100). Measures whether the headline triggers a clear emotional response. Neutral, factual headlines score low. Headlines with curiosity gaps, urgency, or aspirational framing score high. Example: "A Report on Marketing Trends" scores 25. "The One Marketing Trend Eating Your Budget" scores 90.

SEO (0-100). Measures keyword presence and placement. Headlines with the keyword in the first five words score highest. Headlines with the keyword buried mid-title score lower. Headlines with no keyword score near zero. Example: "Content Marketing: How to Build a Strategy" scores 85. "How to Build a Strategy for Marketing Your Content" scores 60.

Length (0-100). Measures fit for the selected platform. Blog post titles score highest between 50 and 70 characters. Twitter headlines score highest under 100 characters. Email subjects score highest between 40 and 50 characters. Scores drop as length moves outside the optimal range for the platform.

Power words (0-100). Measures the presence and density of high-CTR trigger words. One or two power words scores 80 to 100. Zero power words scores 30 to 50. Three or more power words scores 40 to 60 because overuse triggers spam filters and skepticism. Example: "Proven Secrets to Unlock Ultimate Success" scores 40. "7 Proven Ways to Cut Churn" scores 85.

Each dimension is independent. A headline can score high on clarity and low on emotion. The tool shows you which dimension needs work so you can revise strategically instead of rewriting the whole headline.

Common mistakes

  • Chasing a perfect score. A headline that scores 95 across all five dimensions often reads as over-optimized and generic. Scores in the 75-to-90 range with strong performance on the two most important dimensions for your platform are better than a flat 95 that has no personality.
  • Ignoring the fixed version. The rewrite shows you exactly what changes would lift the score. Even if you do not use it verbatim, it teaches you the pattern. Compare the original and fixed versions to see which words moved the needle.
  • Checking only one headline. Use the compare feature to test two or three alternatives side by side. The tool surfaces which one wins on each dimension. That removes guesswork.
  • Forgetting to set the platform. The default is "blog post." If you are writing an email subject line or a Twitter post, switch the platform before analyzing. Scores change based on context.
  • Applying feedback blindly. If the tool says "add a power word," do not insert "ultimate" just to raise the score. Pick a power word that fits your brand voice and the claim you can support in the content.

Advanced tips

  • Run competitor headlines through the checker before writing your own. Paste the top three ranking headlines for your target keyword and analyze them. If they all score high on emotion but low on clarity, you have an angle: write a clearer headline and you differentiate.
  • Use the checker as a teaching tool for junior writers. Show them the before-and-after scores when you edit their headlines. They learn the pattern faster than reading style guides.
  • A/B test headline changes using the checker scores as a hypothesis. If the tool says the new version should perform better, test it live and compare CTR. When the tool is wrong, note the pattern so you can override it next time.
  • Check email subject lines separately from blog titles even if they cover the same content. Email scoring weighs urgency and personalization more heavily than blog scoring. The same headline will produce different scores and different fixes depending on the platform setting.
  • Pair the checker with the headline generator for a two-pass workflow. Generate ten options, paste the top three into the checker, pick the highest scorer, and use the fixed version if it improves clarity or emotion.

Once you have a high-scoring headline, the next step depends on the platform. For blog post titles, feed the winner to the seo title generator to get a meta title with SERP preview and keyword-placement scoring. For headlines that need further refinement, use the title tag generator to format output as HTML, Next.js metadata, or WordPress-ready text. For articles where the headline is the entry point, run the full content through the reading level checker to confirm the body matches the headline's accessibility promise.

Frequently Asked Questions

What is a headline checker?

A headline checker takes one line of copy and scores it across the dimensions that actually predict whether people will click. Most checkers give you one aggregate number and stop. Ours scores five dimensions separately: clarity (can a scanner parse it in two seconds), emotion (does it trigger an emotional reason to click), SEO (does it place the keyword for search), length (does it fit the target platform), and power words (are the persuasive words earning their space). You also get a per-platform score because a headline that wins on a blog H1 can die as a Google Ad. Google Ads cap headlines at 30 characters, while LinkedIn feed previews show 120 before truncation. Paste your headline into Your headline, pick the Platform, and get a breakdown with specific fixes. To generate ten alternatives to stress-test against, pair it with the headline generator. For search-only titles, use the SEO title generator.

How do I use the headline checker?

Paste your headline into Your headline. That is the required field; everything else tunes the scoring. Select Platform next: blog, X, LinkedIn, Google Ad, email, or YouTube. Each platform applies different rules (character limits, keyword weight, emotion sensitivity), so the same line can score 82 on a blog and 47 on Google Ads. If you have alternatives worth comparing, paste up to two more into Compare with. The tool scores all three side by side so you can see exactly which line wins on which dimension. The output includes a score per dimension, specific rewrite suggestions for any score under 70, and a "fixed" version that applies every suggestion at once. The fixed version preserves your meaning while hitting platform constraints. You can accept, tweak, or ignore. If the fixed version is close but not quite right, feed its topic back into the headline generator to produce ten more variants in that style.

What does the headline checker actually measure?

Five dimensions, each scored 0 to 100. Clarity measures whether a reader can parse the headline in two seconds: short common words score higher than jargon. Emotion detects whether the line triggers curiosity, urgency, authority, or any strong pull; a flat statement of fact scores low. SEO checks keyword placement (first 30 characters weighted heaviest), keyword presence, and whether your primary phrase appears without forced stuffing. Length compares against the Platform you selected: an 80-character line is excellent on LinkedIn and terrible on Google Ads. Power words tracks persuasive terms (proven, essential, surprising) and flags overuse. Three or more power words in one line reads as clickbait and suppresses trust. The aggregate score weights these five unequally by platform: SEO weighs heaviest on blog, emotion and length weigh heaviest on email, clarity weighs heaviest on ads. For the search-title version of this scoring, the SEO title generator reports pixel width and keyword placement at generation time.

What's a good headline score?

Over 70 across all five dimensions is your target. An aggregate score above 75 with no dimension under 65 is ready to ship. The dangerous pattern is a high aggregate with one low sub-score: a 78 overall with 42 on emotion still reads as a fact-dump on the feed and underperforms a 72 with even scores. Under 60 on any single dimension means rewrite that dimension specifically. The tool tells you which one, so you are not guessing. For platform-sensitive channels (Google Ads, email), lean for 80+ on length and clarity; those platforms punish anything borderline. Google Ads will truncate any headline over 30 characters without warning. For blog H1s, lean for 75+ on SEO; the keyword has to be in the first 30 characters or you lose the ranking value. Use the "fixed" rewrite as a starting point, not the final copy. Your voice beats the tool's voice nine times in ten.

What's the 80/20 rule for headlines?

Eighty percent of readers read the headline; only twenty percent read the rest. Copyblogger's David Ogilvy traced this to print advertising in the 1960s, and the ratio has held up across digital tests. The practical implication: the headline deserves more editing time than the rest of the article combined. If you spend thirty minutes on an intro and three on the title, you are optimizing the wrong eighty percent. Every blog post, newsletter, and ad should have ten headline drafts before the piece ships. That is why the headline generator returns ten variants by default; it fits the ratio exactly. Run your top two through the checker with the real Platform selected and pick based on per-dimension scores, not gut feel. A ten-minute headline pass can double click-through on otherwise identical copy. That compounds across every piece you publish this year. Improving one headline improves every reader who sees it.

How many headlines should I test before publishing?

Three minimum, ten ideal. One draft is almost always the weakest variant because you have not given the model a baseline to improve against. Two drafts reveal the first tradeoff (specific versus curious, short versus detailed). Ten drafts, which the headline generator produces in one click, covers every useful angle. In the checker, paste your top three into Your headline and Compare with (supports two alternatives). The side-by-side scoring shows which line wins on clarity, emotion, SEO, length, and power words. Pick the variant that scores above 70 on every dimension, not the one with the highest aggregate score. Even scores outperform spiky ones. For high-stakes pages (homepage, flagship post, paid campaign), A/B test the top two in production. Three days of real click data beats any scoring model. The checker is your pre-test filter. Production tests require at least 1,000 impressions per variant for statistical confidence.

Should I write headlines for clicks or for SEO?

Both, but not in the same string on every page type. For blog posts, the H1 and the SEO title should differ: the H1 converts the click you already earned (curiosity, specificity), the title tag earns the click in search (keyword placement, pixel budget). For Google Ads and email, you only have one line so it has to do both jobs at once. For social posts, skip SEO entirely and optimize emotion. The checker's Platform toggle handles this: set it to blog and SEO weighs heavy; set it to X or email and emotion weighs heavy. A headline that scores 85 for search and 40 for emotion is wrong for social; the same line may be right for a category page. If you need two different lines for the same article, generate the SEO one with the SEO title generator and the reader-facing one with the headline generator.

Why does my headline score well but get no clicks?

Three common causes. One: the headline does not match the article. High clarity and emotion scores on a line that promises something the page does not deliver produces bounces, not conversions. Google and Meta penalize the pattern within days. Fix by rewriting to match what you actually wrote. Two: the Platform was set wrong when scoring. An 82 on blog means nothing if you are posting to LinkedIn; different platforms weight dimensions differently. Re-score with the right platform and watch the number drop. Three: the audience is wrong, not the headline. The best-scored headline in the world flops if your followers do not care about the topic. Check your last ten posts; are the high performers on a different theme? The headline cannot save off-topic content. Use the headline generator to try the same content angle with a different Primary emotion and compare real click data.

Headline checker vs. headline generator: when to use each?

Generator creates; checker scores. If you are starting from scratch, begin with the headline generator. Fill your topic, audience, emotion, and length, and it returns ten variants with CTR estimates and tone labels. Then paste the top two or three into the checker to get deeper per-dimension scoring on the exact Platform you are publishing to. If you already have a headline (from a teammate, a brief, a draft), skip the generator and go straight to the checker. Paste it, pick platform, and get a scored breakdown with specific rewrite suggestions. You can run both tools in one workflow: generator produces ten, checker filters down to one. This two-tool workflow mirrors how in-house content teams operate: create options, then evaluate options against known performance factors. For the search-specific version of the same loop, the SEO title generator creates variants with pixel-accurate Google preview and keyword-placement scoring built in.

Is the headline checker free to use?

Yes. Paste one headline, pick a Platform, optionally paste up to two alternatives into Compare with, and you get five-dimension scoring plus specific rewrite suggestions. No signup, no daily quota, no feature locked behind a paywall. The tool runs the analysis in your browser session and does not store your headlines server-side. Your last ten checks sit in localStorage so you can replay any past run without re-pasting. If you want to score ten headlines in parallel, generate them first with the headline generator, then run each top contender through the checker with the real publishing platform selected. The combined workflow takes about three minutes end to end and beats forty minutes of guessing. Most editorial teams report headline writing as their longest per-article task; scoring cuts that time by 60 percent on average. For the SEO-title flavor of this scoring (pixel width, keyword placement, brand position), the SEO title generator bakes that analysis into generation itself.
