Headline Analyzer
Score a headline or subject line on length, numbers, power words — rules shown.
About this tool
Type a headline and get a score with the reasons: word and character counts against the sweet spots, whether it fits Google's title space, a number, a question, power and emotional words, and the ratio of common words. Suggestions follow from whichever rule fired.
What headline scores actually measure
Every headline analyser — the famous ones included — is a bundle of heuristics distilled from what tends to get clicked on average: a specific number (“7 ways”, “in 12 minutes”), a concrete benefit word, a length that fits where it will be shown, a promise that says who it's for and what they get. Those correlations are real and worth checking against, which is why the rules here are printed rather than hidden behind a number. What no analyser measures is whether the promise is true, whether your audience cares, or whether the article delivers — and a headline that scores 95 and disappoints is worse than a 60 that's honest. Use the score as a checklist for the common failures (vague, too long, no specific claim) and then test: the A/B test calculator says when one headline really beat another. The SERP preview shows the exact pixel cut-off on Google, the character counter the platform limits, and the readability checker grades the article underneath.
Frequently asked questions
What is a good headline score?
Above about 70 means the common boxes are ticked. It does not mean the headline is good for your readers — only a test tells you that. Use the listed reasons, not the number.
How long should a headline be?
6–12 words and under about 60 characters shows in full on Google and in most feeds. Email subject lines are cut at around 40 characters on phones.
Do numbers really help?
In most published tests, yes — odd numbers and specific figures signal a concrete, scannable piece. It’s a tendency, not a law.
Is the headline sent anywhere?
No — the scoring runs in your browser.
