Event website

  • Definition: An event website's sole purpose is to advertise a specific or repeatedly occurring activity that is open to the public, organised and/or hosted by the European Commission. The website can be temporary and provide information about an event before, during and after it takes place. It can be complemented by a campaign. Event websites are only allowed for large and complex events that cannot be accommodated by the events content type.
  • Scope: Events may have specific requirements.

Campaign website

  • Definition: A temporary, online communication endeavour dedicated to promoting a single or several thematically linked activities, initiatives, services or products. The website may form the online part of a broader campaign, communicated by other channels such as print and social media.


  • Definition: Regularly updated websites dedicated to publishing general features and news items about specific European Commission activities, from an individual perspective or via a corporate (DG/Agency-managed) newsletter/magazine.

Harmonised websites Group 3

Partnership websites

  • Definition: A partnership website is a website where the European Commission is a cooperating partner in its creation but is not the sole owner of the information contained therein. It is a joint effort between the EC and non-EC partners in terms of concept, budget, management and maintenance and requires its own individual form of governance and custom style guides to accommodate possible co-branding.
