Ask an AI for ten headlines and you’ll have them in seconds. Ask for ten more and you’ll have those too.
Writing headlines used to be the slow part. Now it’s choosing them. And most people still choose the way they always have: they read the list and pick the one that sounds best. That’s the one test that no longer works.
Why “sounds good” is the wrong test
AI writes fluent headlines by default. Every option on the list reads smoothly, so polish no longer tells you anything.
Worse, the headlines that sound best are often the weakest. AI drafts lean on the same moves: wordplay, big verbs like “unlock” and “elevate,” and promises with nothing behind them. They sound like marketing. They don’t tell a reader what they’re getting.
So instead of asking “Which one do I like?”, run every headline through five questions.
The five-point headline test
1. Could a stranger say what you sell?
Show the headline to someone who has never heard of the business. If they can’t tell you what it offers, the headline has failed, however good it sounds.
“Elevate your financial journey” could be a bank, a coach or an app. “Bookkeeping for small businesses, done in 3 days” can only be one thing.
2. Is there anything specific in it?
A number, a time frame, a place, a named result. Specifics are what make a promise believable, and they’re the first thing AI leaves out, because it doesn’t know them.
If none of the options has a specific detail, the problem isn’t the headline. It’s the brief. Give the AI the facts (prices, turnaround times, results) and ask again. (How CopyZap asks for missing facts.)
3. Does it speak to this reader’s situation?
The same service needs a different headline for someone who has never hired a bookkeeper and someone who wants to switch from the one they have. The first needs to hear what bookkeeping does for them. The second needs to hear why you’re better.
Ask: who will read this, and what are they worried about when they do?
4. Do the first words carry the point?
People scan. Usability research has found that readers scanning a page often take in only the first two words of a line. A headline that opens with “Finally, a firm that…” spends those words on nothing.
Compare “Month-end closed in 3 days” with “Discover how our team can help you close month-end faster.” Same idea. Only one makes it in the first glance.
5. Can every claim be backed up?
AI will happily write “Trusted by 500+ businesses” for a firm that has 80 clients. A specific headline that isn’t true is worse than a vague one: it costs the client trust, and it can cost them more than that.
Before a headline goes anywhere, check every number and promise in it against what the business can prove.
A worked example
Here are five AI-written headlines for the same bookkeeping firm, run through the test. ✓ passes, ✗ fails, ? needs checking.
| Headline | Clear | Specific | Fits reader | Strong start | Provable |
|---|---|---|---|---|---|
| Elevate Your Financial Journey with Tidewell | ✗ | ✗ | ✗ | ✗ | ✓ |
| Unlock Stress-Free Finances Today | ✗ | ✗ | ✓ | ✗ | ✓ |
| Trusted by 500+ Small Businesses | ✗ | ✓ | ✗ | ✓ | ? |
| Bookkeeping That Gives You Your Weekends Back | ✓ | ✗ | ✓ | ✓ | ✓ |
| Close Your Books in 3 Days, Not 3 Weeks | ✓ | ✓ | ✓ | ✓ | ? |
Swipe the table to see all five checks.
The last one wins, as long as the firm really closes month-end in three days. If it does, that’s the headline. If it doesn’t, “Bookkeeping That Gives You Your Weekends Back” is the honest runner-up, and it would also make a good email subject line.
Notice what happened to the two that sounded most like marketing. They failed almost every question.
When two headlines tie
Sometimes two options pass all five questions. Then you have three choices:
- Test it, if the page gets enough traffic for an A/B test to mean something.
- Pick the clearer one, if it doesn’t. Clarity rarely loses.
- Say it’s a close call when you present it to the client. Don’t dress up a tie as a clear win. (How to present a close call.)
