Every marketer wants to write the next Just Do It. Most end up writing Quality You Can Trust. Somewhere in between these two lies ‘Bolo Zubaan Kesari’.
But jokes aside, the difference isn’t creativity. It’s understanding how memory works.
We often talk about taglines as if they’re clever pieces of copy. They’re not. They’re memory devices. The best ones compress an entire brand philosophy into a handful of words that our brains find effortless to retrieve.
That’s why decades later, we still remember taglines from brands we’ve never even bought.
The real question isn’t what makes a tagline catchy?
It’s what makes an idea impossible to forget?
Your brain doesn’t reward information. It rewards efficiency.
Human beings encounter thousands of commercial messages every day. Our brains simply cannot store all of them. So, they don’t try.
Instead, they compress.
Cognitive psychology refers to this as chunking—our tendency to group information into smaller, meaningful units that are easier to remember. George A. Miller’s landmark paper, The Magical Number Seven, Plus or Minus Two, showed that people naturally organize information into manageable chunks to improve recall.
A great tagline performs exactly this function.
Instead of asking consumers to remember product specifications, brand values, campaign narratives and category claims, it offers a shortcut.
“Think Different.”
An entire worldview in two words.
The best taglines don’t explain. They imply.
One of advertising’s oldest temptations is over-explanation. Brands want consumers to know everything.
But memorable communication usually does the opposite.
It leaves just enough unsaid for the audience to complete the thought themselves.
Psychologists call this the generation effect—people remember information better when they’ve had to mentally generate or complete it rather than simply receive it.
Think about Nike.
“Just Do It.”
Do what?
The campaign never needed to answer. Every consumer supplied their own answer. In fact, the less specific the line became, the more personally relevant it felt.
Familiarity is a marketing superpower.
Here’s something uncomfortable truth for marketers like me. Consumers don’t necessarily prefer the best ideas.
They often prefer the most familiar ones.
Psychologist Robert Zajonc demonstrated this through the mere exposure effect: repeated exposure to something increases our liking for it—even without conscious evaluation.
This explains why brands that constantly reinvent their messaging often struggle to build memory.
Marketing teams love novelty but memory loves consistency.
- McDonald’s has been saying I’m Lovin’ It for over twenty years.
- L’Oréal has barely touched Because You’re Worth It since the 1970s.
They’re not repeating themselves because they’ve run out of ideas. They’re investing in memory.
Sound is doing more work than we realise.
Read these aloud.
“Have a Break. Have a KitKat.”
“Maybe She’s Born With It. Maybe It’s Maybelline.”
There’s a rhythm to both.
Linguists have long argued that rhyme, repetition and phonetic symmetry improve recall because they reduce cognitive processing effort. Research also points to what’s known as the rhyme-as-reason effect—people often perceive rhyming statements as more truthful and memorable than equivalent non-rhyming ones.
It’s why political slogans, nursery rhymes and advertising often borrow from the same linguistic toolkit.
Features expire but identity compounds.
One reason so many taglines age badly is that they’re written around products instead of people. Technology changes. Prices change. Competitive advantages disappear.
But a strong identity rarely wavers.
Royal Enfield has never just sold motorcycles. It sells a certain way of experiencing the road.
Apple users can rarely explain why their devices feel better than the rest.
Fevicol rarely explains why their adhesives are strong. It sells the idea of bonds that simply don’t break.
They’re all selling ways of seeing yourself.
This idea aligns closely with the work of marketing professor Jennifer Aaker, whose research on brand personality showed that consumers often relate to brands in much the same way they relate to people.
The strongest taglines reinforce identity more than functionality.
Distinctiveness beats differentiation.
Marketing often obsesses over differentiation. Byron Sharp argues that’s the wrong battle.
In How Brands Grow, Sharp suggests that brands primarily grow through mental availability—being easily thought of in buying situations. That requires more distinctiveness than uniqueness.
Simply put, a tagline doesn’t need to say something no one has ever said before. It needs to sound unmistakably like you.
If another company could borrow your tagline tomorrow without anyone noticing, it probably isn’t building distinctive memory structures.
Culture decides whether your taglines survive.
Because iconic taglines aren’t products of language alone.
They’re products of timing.
Just Do It arrived when fitness was becoming cultural identity.
Think Different emerged as Apple positioned itself against corporate conformity.
Because You’re Worth It entered conversations about female agency decades before purpose became marketing shorthand.
In hindsight, these lines feel inevitable.
At the time, they reflected cultural shifts that brands had the courage to own.
That’s much harder to automate even in the age of AI where you can get hundreds of technically sound taglines in seconds.
The irony is that consumers rarely remember advertisements. They remember fragments. A line. A melody. A logo. A feeling. Perhaps that’s the simplest definition of a great tagline. Not one that people can recall. One they eventually stop realising they’re recalling at all.
As proof of this fragmentation, I’m going to sum up this article with a tagline that I remember singularly even without remembering the brand name. Why some taglines never leave your mind? Dobaara mat poochna!
