The document summarizes the results of a marketing campaign by Colgate to drive perceptions that it is recommended by dentists. The campaign included 880 roadside posters. Research found the posters significantly increased perceptions of Colgate being recommended by dentists (up 19%) and strengthened other key brand perceptions. Posters also grew associations with terms like "clinical", "expert", and "scientific". Finally, those who saw the posters were more likely to have recently purchased Colgate (up 21%) and recommend it in the future compared to those not exposed to the posters.
