Methodology is based on a tagging system of the advertising formats comprising an online campaign. Exposure, or lack thereof, to the advertising campaign will be identified through the 25,000 active panellists of the Médiamétrie//NetRatings Panel.

The Meter, with which our panellists are equipped, automatically uploads the information when a web user has exposure to the campaign.

This information is stored throughout the campaign, including both the characteristics of the panellists exposed (profile) as well as the entirety of their web surfing behaviour.

An overview of exposure:

• Coverage, repetition, contacts
• Performance in target groups
• Contact accumulation and frequency distribution graphs
• Contribution of sites to the campaign

An analysis of impact on web surfing behaviour:

• Engagement with the advertiser’s site (visitors, sessions, time spent)
• Conversion rate (access to secure pages)
• Online searches (keywords typed)

Image/post-test overview:

• Spontaneous/assisted notoriety of the brand/campaign
• Attribution of the message
• Intention to purchase
• Etc...

The results of the online study can be adjusted to usage actually observed via the Médiamétrie//NetRatings Panel.
