Comparison: how it works

Comparative advertising sets a brand against a competitor, either by name or so clearly that everyone knows who is meant. It ranges from side-by-side tests and price comparisons to public jokes at a rival's expense and open letters between brands.

How to spot it

  • A named or unmistakable competitor.
  • A test, a contrast or a challenge the audience is invited to judge.
  • Underdog positioning against a market leader.

Why it works, and the risks

Comparison creates drama and gives a smaller brand a bigger stage. It can also invite retaliation, legal challenge or sympathy for the target, so the most admired examples are usually confident, specific and good-humoured.
