Headline Analyzer

About the Headline Analyzer

Type a headline, or several (one per line, up to 10), choose what it is for — a blog post or page title, an email subject line or an ad — and get a score out of 100 with every part of it shown: length in words, whether it fits (the width of a search result, a phone inbox or the 30-character Google Ads limit), the balance of common, uncommon, emotional and power words, the headline type, numbers, sentiment and readability. Points come off for shouting capitals, repeated punctuation, teasing phrases and what ad platforms and Gmail reject.

The rules are MySmartCoPilot’s own rules of thumb and are published in full on this page, with the word lists behind them. The score is guidance, not a prediction of clicks: no tool can know how your readers will react, and Google’s own advice is that a title should describe the page and avoid exaggerating.

Without a pass you see a free preview: the score, type and sentiment of your headline, with the first rows of its word balance, score table, tips and comparison. The whole analysis, and copying or downloading it, unlock with a Pro pass.

How the score works

The parts add up to 100 points (90 when the sentiment word list can’t load; the score is then scaled to 100). Points taken off come after.

• Length in words (20): full points for 6–12 words (blog or page title), 4–9 (email subject) or 2–5 (ad headline); 12 points just outside those ranges (4–15, 2–12, 1–7), 4 points beyond.
• Fit (15): a blog title gets full points up to about 600 px wide (Arial at 20 px, the width SEO tools use for a desktop result), 10 if it is shorter than 30 characters, 8 up to 700 px and 3 beyond. An email subject gets full points up to 45 characters, 9 up to 60 and 3 beyond. An ad headline gets 15 points up to the 30-character Google Ads limit and none above it.
• Word balance (30): common words 20–40% of the words earn 10 points (6 for 10–20% or 40–55%, 2 otherwise); uncommon words 8 points from 25% (5 from 10%, 1 below); emotional words 6 points when there is at least one and they are at most 30% of the words (3 above); power words 6 points for one or two (3 for three or more). Numbers written in digits are left out of the balance; number words (seven, ten) count as common words.
• Type (10): a list, how-to, question, comparison, guide, review or announcement gets 10 points; a plain statement 4.
• A number (5): a digit or a number word.
• Sentiment (10): the VADER compound score of the headline (−1 to +1): 10 points from ±0.4, 7 from ±0.15, 4 below that (a neutral headline).
• Readability (10): full points when at most 20% of the words have three or more syllables, 6 up to 35%, 2 beyond.
• Taken off: 5 for two or more words in capitals (or all capitals; acronyms such as SEO or USA don’t count), 5 for repeated punctuation (!!, ?!), 15 for a teasing phrase, 3 for more than one emoji (10 for any emoji in an ad headline), 10 for a “Re:” or “Fwd:” on an email that isn’t a reply. An ad headline over 30 characters is capped at 40; a fake reply prefix at 45.

Where the rules come from

• Google sets no length for titles but cuts title links as needed, typically to fit the device width, and asks for descriptive, concise titles without keyword stuffing.
• Google’s guide to helpful, people-first content asks whether the main heading or page title gives a descriptive, helpful summary and avoids exaggerating or being shocking in nature: the reason teasing phrases cost points.
• Google Ads limits headlines to 30 characters and counts each double-width (Chinese, Japanese, Korean) character as 2; its editorial policy disapproves gimmicky capitals, repeated punctuation and emoji.
• Gmail’s sender guidelines say not to start a subject with Re: or Fwd: unless the message is a real reply or forward.
• Sentiment uses VADER, the open-source lexicon and rules by C.J. Hutto and Eric Gilbert that the Sentiment Analyzer runs.

The ranges for words, characters and the word balance are MySmartCoPilot’s own rules of thumb, not published standards.

Limitations

• The word lists, syllables and sentiment are for English headlines.
• Word lists can’t read context: a word used ironically or in another sense keeps its group.
• The search-result width is an estimate in a standard font; the real cut depends on the device and Google’s layout.
• No score predicts clicks or opens; test real versions with your audience when it matters (an A/B test).
