Corsodyl Advertising Campaign Awareness Research
JCDecaux, a leading European out-of-home advertising company approached Opinium with a brief to conduct two waves of market research to assess the impact of an advertising campaign.
Opinium was commissioned to conduct research assessing the effectiveness and visibility of a national UK roadside billboard campaign for Corsodyl mouthwash.
We recommended Opinium AdCheck which was ideal for the requirements and pre and post campaign research tracked changes awareness of the campaign, gum disease awareness in general, and of Corsodyl mouthwash as an effective treatment for this issue.
Opinium Research carried out two waves of online research of UK adults aged 18+.
Our sophisticated research survey software allows us to show a variety of images and video. In this case, the following image representing the JCDecaux billboard was shown to respondents.
The first survey of 2,104 UK adults took place between 16th and 18th July 2010, immediately before 1,300 JCDecaux 48 sheets (large billboards) depicting the ad above were displayed around the country.
The second survey of 2021 UK adults took place between 2nd and 4th August 2010, immediately following the advertising campaign. Awareness of Corsodyl mouthwash as an effective treatment for gum disease was higher post campaign, and the increase seen was larger in degree than for other major competitors.
The difference in perceived effectiveness of Corsodyl as a treatment for gum disease was also more marked among those living in areas where the campaign was displayed, than among those in other areas.
We provided an in depth analysis into the research and compiled a lengthy report for the business.
