The slogan that gets the warmest reaction in a meeting may not be the line people remember later. A choice based only on immediate liking is especially weak when the slogan needs to help customers identify a brand among alternatives.
Hodges, Estes, and Warren analyzed more than 800 brand slogans and ran laboratory, eye-tracking, and field work. Across their studies, easier-to-process wording tended to be more liked but less memorable. Shorter slogans without the brand name and with more common or abstract words were more liked; longer slogans that named the brand and used less common, more concrete words tended to be remembered better. The relationships are population-level findings across their study conditions. They do not mean a business should deliberately write an awkward slogan or expect a particular line to perform from its word count alone.
Define the job before writing lines
A slogan can help a new audience understand the offer, add a distinctive phrase to a familiar brand, or reinforce a campaign. Those jobs need different tests. If people do not know the brand yet, a clever line that could belong to any competitor may be weak even if it is liked. If the brand name is already visible in every use, repeating it in the slogan may be unnecessary. Write the intended placement and task at the top of the shortlist.
For each candidate, ask: What does this line mean in plain language? What does it imply about the product? Can we support that implication? Is it usable in the languages and formats where it will appear? A separate brand voice guide helps teams write consistently; this test decides whether one public-facing line does its particular job.
Run a small two-stage test
Show each line in a realistic application, with the same design treatment and exposure time. Ask participants which one they prefer and why, but record that as liking, not success. Ask what kind of company each line belongs to and which promise they think it makes. Remove any candidate that implies an unsupported fact or obscures the actual category.
After a delay and a distraction task, ask participants what they remember without showing the list. Record exact and approximate recall. Then show the lines and ask which brand each belongs to, including plausible competitor names or a “not sure” option. This captures a problem a preference poll misses: a line may be memorable but not attributable to its owner.
| Measure | Decision it informs |
|---|---|
| Liking | Whether the wording feels appealing at first contact |
| Comprehension | Whether the intended offer and promise are understood |
| Delayed recall | Whether the line survives without a prompt |
| Brand attribution | Whether memory points back to the right company |
One workshop or small test can reveal misunderstandings; it cannot estimate future campaign lift. If the slogan will carry a major media budget, test it with the relevant audience, language, and placements at a scale appropriate to the decision. Choose the line that performs the stated job without inventing a promise, then document how it may be used so later campaigns do not silently change its meaning.
