Headline Analyzer — guide & how to use

What it does

This headline analyzer scores any headline from 0 to 100 and tells you exactly what to fix. It blends five factors copywriters obsess over: length (does it fit the platform?), word balance (the right mix of common, uncommon, emotional and power words), emotional value (EMV%, the Advanced Marketing Institute metric), clarity (no jargon, vague filler or all-caps), and keyword placement (present and front-loaded for SEO). Everything runs privately in your browser.

How to use it

  1. Paste your headline into the box.
  2. Optionally add a target keyword (so it can check SEO front-loading) and pick where it will run (the ideal length changes per platform).
  3. Read the overall score & grade, the five sub-score bars, and the prioritized fixes below them. Apply a fix, re-read the score, repeat.

Worked example

Headline: 7 Proven Ways to Write Headlines That Actually Get Clicks (context: blog, keyword: write headlines). This scores 59 / 100 (Fair) — and the breakdown shows exactly why:

The top fixes the tool returns are therefore “add an emotional word” and “tighten the word count.” Apply both — 5 Proven Ways to Write Headlines People Love — and the score jumps to 81 / 100 (Excellent): the emotional word “love” lifts EMV and balance, fewer words tightens length, and “write headlines” stays intact and front-loaded. That’s the loop the tool is built for — read the weak sub-score, apply its fix, re-score. (Exact scores depend on your specific wording — a given headline always scores the same, but the iterate-and-re-score loop matters more than hitting a target number.)

How scoring works (so the number is reproducible)

Accuracy & limits — read this. This is a heuristic scorer, not a click-through predictor. No headline tool can guarantee clicks; the score reflects alignment with documented best practices, not measured performance. Length targets are guidelines — Google truncates by pixel width (~600px), so the 60-character cutoff is a band with a margin, not an exact rule. The sentiment finding (negative words slightly lift clicks) comes from a 2023 news-headline study and may not generalize to email, ads or B2B, so sentiment is reported as insight and never auto-penalized. The word lexicons are English-only; non-English headlines show a calibration warning. EMV% is a simple ratio and can be gamed, so it sits alongside the composite, not above it. The default weights (length .20 / balance .25 / emotion .20 / clarity .20 / keyword .15) are an editorial choice, documented here so the score is explainable.

Frequently asked questions

What makes a good headline score?

80–100 is Excellent (publish), 60–79 Good (minor tweaks), 40–59 Fair (revise) and 0–39 Weak (rewrite). The score blends five factors: length fit, word balance, emotional value (EMV%), clarity and keyword placement. It measures alignment with documented best practices — it does not predict clicks.

What is the ideal headline length?

For blog and SEO titles, aim for about 55 characters (Google truncates search results near 60 characters) and 6–9 words. Email subject lines do better around 40 characters and social headlines around 70. The tool scores length against the band for the context you pick.

What is EMV% (Emotional Marketing Value)?

EMV% is the Advanced Marketing Institute metric: the share of words in your headline that are emotional. Professional copywriters typically land 30–40% and top copywriters 50–75%. It is a simple ratio, so it can be gamed — we show it alongside the composite score, never instead of it.

Should my headline be positive or negative?

A 2023 study of news headlines (Nieman Lab / PNAS) found a single negative word raised click-through about 2.3% and positive words lowered it about 1.0%. That effect is small and context-specific, so we report sentiment as information and never penalize a positive headline — positive headlines convert well in many niches.

Does the keyword field affect my score?

Only if you fill it in. If you add a target keyword, the tool checks whether it appears and whether it is front-loaded (before character 60, ahead of search-result truncation). If you leave it blank, the keyword factor is dropped and the remaining four are re-weighted so you are not penalized for skipping it.

Will a high score guarantee more clicks?

No. This is a heuristic scorer, not a click-through predictor. No tool can guarantee clicks. The score reflects how well your headline follows length, emotion, clarity and keyword best practices — test real headlines with your audience to know what actually performs.

Is it free and private?

Yes — 100% free to analyze. All tokenizing, lexicon lookups, scoring and rewrites run privately in your browser with no network calls. A free account is only needed to download, save or share your results.

The word lists are a curated set bundled with the tool, adapted from the power-word, emotional (EMV) and common-word lexicons popularised by CoSchedule and the Advanced Marketing Institute; they are English-only, so scoring is calibrated for English headlines.
