"Give me some headlines" — the prompt with no way to pick a winner
A headline prompt that returns twenty options and no way to choose, plus the version that ranks them against a real criterion.
The prompt, as typed
Give me some headlines for my landing page. Make them catchy.
What it leaves the model to guess
- What the page is selling and to whom
- How many headlines and how long
- What makes one headline better than another here
- The objection the headline has to survive

The rewritten prompt
You are a conversion copywriter.
Product: {{product}}
Audience: {{audience}}
What they are currently doing instead: {{status_quo}}
Main objection: {{main_objection}}
Write 8 landing page hero headlines, max 12 words each.
Then rank the top 3 by:
1. How immediately clear the offer is to someone who has never heard of us
2. How directly the headline neutralises {{main_objection}}
Constraints: no questions as headlines, no "unlock", "revolutionise",
"supercharge", no wordplay that requires a second read.
For the top pick, write one line on what it assumes about the reader. Why the rewrite works
A list of twenty catchy options moves the work back to you. Naming two explicit ranking criteria means the model has to defend a choice, and the defence is usually more useful than the headlines.
Common questions
- Why does this prompt score badly?
- It scores 10 out of 100 (F) because it leaves the model to decide 4 things you already know: what the page is selling and to whom; how many headlines and how long; what makes one headline better than another here; the objection the headline has to survive.
- Does a longer prompt always score higher?
- No. The rubric rewards named inputs, a fixed output format and an explicit rule for choosing between options. Extra prose without those adds length and no score.
- Will this rewritten prompt work in ChatGPT and Claude?
- Yes. It is plain text with placeholders you fill in before running, so nothing in it is specific to one model or vendor.
