What the scorer checks

Length — titles in the 40–70 character range read fully in search and suggested feed without truncating.

Numbers — a digit in the title adds specificity and signals a concrete outcome.

Question hooks — a question mark opens a curiosity gap viewers want closed.

Parentheticals — a bracketed detail adds context without lengthening the headline.

Power words — terms like “proven,” “mistake,” or “honest” that carry weight in a scan.

Each factor above shows up as a scored pill under every variant, so you can see exactly why one title outranks another — not just that it does.

The scorer reads your draft, detects its likely type — how-to, list, review, comparison, reaction, or story — and pulls the formulas most relevant to it before scoring and ranking the results.

Enter a draft

Paste in whatever working title you already have — rough is fine, the lab only needs a topic to work from.

Run the test

The scorer classifies your title, builds up to six formula-based variants, and grades each on estimated CTR potential.
