Why test the line

What you mean is not always what people hear

A line that reads well in a meeting room can sound vague, hard to believe or just like a competitor. Message testing compares what you meant with what people actually take away, before the line goes on a website, a pack or a billboard. It shows where a message lands and where it falls short.

Where a line is misread

Setting what people heard next to what you meant shows the line that needs a rewrite.

Verdict

"Lower bills" leads

"Learns your routine" is misread, so it gets a rewrite.

The lead line

Example: choosing lines for a smart thermostat

A home-energy company has 14 lines about its smart thermostat, from "Lower bills without thinking about it" to "A home that learns your routine". US homeowners see the lines in sets of four and pick the most and least convincing in each set. The top three then go to a short follow-up in which people rate each line and say what it means to them. The team sees which lines lead overall, which ones split by age, and which one people misread before choosing what goes on the website.

  • Lower bills without thinking about it

    Lead

    Clear, relevant and the most convincing in the best-worst sets.

    It goes on the website.

  • Set it once. Save all year.

    Back-up

    The clearest line, a little less believed.

    Keep it for ads.

  • A home that learns your routine

    Rework

    It sounds new, but over-55s read it as the thermostat watching them.

    Say what it learns, and why.

Ask the studyAnswers from your own data

Which line splits by age?

"A home that learns your routine" appeals to under-35s, but over-55s more often read it as the thermostat watching them. The gap is significant.

Step by step

How a message test runs

From a list of lines to the one that lands.

  1. 01

    List the messages

    Paste in your lines. They should be similar in length and style so the comparison is fair, and we go through the wording with you before fieldwork.

  2. 02

    A few lines: rate each one

    With a short list, each person rates the lines one at a time, in a random order, on clarity, believability, relevance and appeal.

  3. 03

    Many lines: pick best and worst

    With a long list, people see four lines at a time and pick the most and the least convincing. Every line ends up with a score and a rank, and you can see how far apart they are.

  4. 04

    Ask what it means

    People say in their own words what a line is telling them. Setting that next to what you meant shows where a line is misread.

  5. 05

    Read the results by audience

    Compare groups such as age bands or current and lapsed customers, then download the deck or the workbook.

  6. Then: decide

    "Learns your routine" is misread, so it gets a rewrite.

FAQ

Questions, answered

How many messages can I test at once?

A short list can be rated line by line. For a longer list, a best-worst design works better, because people only compare four lines at a time. We suggest the route that fits your list.

How is this different from claims testing?

Claims testing checks product statements, such as "no added sugar", for belief and appeal. Message testing covers wider lines: taglines, value propositions and campaign ideas.

Can we hear why a line does not work?

Yes. People explain in their own words, and you can add video or audio answers in which an AI interviewer asks up to three follow-up questions. For longer conversations, ask us about interviews with our researchers.

Should I test lines on their own or inside an ad?

Start with the lines on their own to pick the strongest few. Once a line sits inside a finished ad, the visuals and voice change how it lands, so test the ad as a whole with video, static or audio ad testing.

Send us the messages and tell us who needs to believe them. We will suggest the simplest test that gives you a clear answer.
