Page 5: Evaluating the advertising campaign

Johnsonjohnson 5 Diagram 4The evidence that the success of Clean & Clear in the late 1990s was affected by the new advertising campaign included the following:

  • Increased advertising awareness (i.e. the extent to which consumers could associate the advertising with the brand) in absolute terms and in relation to other brands.
  • Brand awareness also increased in the same period by 49%.
  • Research into the views of teenage girls showed that, for the first time, girls were enthusing about Clean & Clear advertising, even laughing about how true it was to their lives and attitudes towards skincare.
  • An econometric model, which takes account of the different factors that might affect sales growth, showed that without the ‘Real Girls’ advertising campaign, Clean & Clear’s rise in value share would have come to a hal.

A range of other factors can also be discounted as having led to the success of Clean & Clear in the late 1990s:

  • No new products were launched and there were no product reformulations or changes in packaging
  • There were no significant changes in factors relating to distribution
  • There were no price cuts - in fact prices actually rose a little compared to the competition
  • Advertising spend – relative to rivals - did not rise
