Headline Analyzer: Score and Rewrite Your Headline for Clarity and Conversions

What a headline analyzer checks

The headline analyzers most people have used come from the content marketing world and were built for blog post titles and email subject lines. They score things like word count, character count, the balance of common, uncommon, emotional, and power words, whether the headline starts with a number, and sentiment. Those scores are genuinely useful for a headline whose job is to earn a click in a feed or an inbox.

A landing page headline has a different job. The visitor has already clicked. The headline now has to confirm they are in the right place, state what the product does, and name who it is for, all within the two seconds before they decide whether to keep reading. Optimizing that headline for click-appeal metrics is optimizing for the wrong outcome.

Why word-count scores mislead on landing pages

Formula-based scoring rewards patterns that correlate with clicks in aggregate: a certain length, an emotional word, a number near the front. The problem is that correlation was measured on headlines competing for attention, not on headlines confirming a match after the click. A landing page headline scoring poorly on a blog-title analyzer can be close to perfect, because it is doing a job the scoring model does not measure.

The clearest example is specificity. "Convert a PDF bank statement to CSV in under 30 seconds" will score unremarkably on power words and emotion. It is also a far better landing page headline than an emotionally charged alternative that never says what the product does, because it answers the only question the visitor is actually asking. Treat formula scores as a spelling check rather than a verdict.

What actually makes a landing page headline work

Four tests, in order. They catch most of what goes wrong.

• Does it name an outcome rather than a category? "The modern platform for growth teams" describes a shelf in a store. Name the result and who gets it.
• Does it match the ad, email, or search result that brought them? A mismatch between the promise clicked and the headline landed on is one of the largest sources of bounce, and it is invisible if you only ever look at the page in isolation. This is what message match means in practice.
• Is it specific enough to be falsifiable? Numbers, timeframes, named integrations, and concrete nouns all beat adjectives. If a competitor could paste your headline onto their own page unchanged, it is not saying anything.
• Would a stranger understand it without the subhead? The subhead should add detail, not rescue meaning. If removing it makes the headline unintelligible, the two are the wrong way round.

How long should a headline be?

Long enough to be specific, short enough to be read in one glance, which in practice usually lands between six and fourteen words for a landing page. Length is a consequence, not a target. The common failure is not a headline that is too long but one that is short because it is vague, since vagueness compresses well and says nothing.

Where length genuinely matters is the interaction with the subhead. A tight headline naming the outcome plus a subhead carrying the qualifier and the audience usually outperforms one long headline trying to hold all of it. Split the job rather than trimming words out of the part that carries the meaning.

Headlines and answer engines

One change worth making now: buyers increasingly ask ChatGPT, Claude, Gemini, or Perplexity to shortlist tools before they visit any website. Those systems extract from HTML text. A headline rendered inside a hero image, a video, or a JavaScript component that never resolves into plain text is invisible to them, however good it reads to a human.

So the practical rule is that your H1 should be real text, should appear exactly once, and should state plainly what the product does for whom. That is also what makes it work for search, which is a rare case where the human, the search engine, and the answer engine all want the same thing.
