Undue prominence
The BBC must not unfairly promote any commercial organisations. Therefore great care must be taken when linking to any commercial site to ensure that we do not give the impression that the BBC is unfairly endorsing any commercial product or service.
BBC sites with links to commercial sites should normally explain the criteria by which the links were assessed in order to avoid the impression that the BBC is unfairly endorsing any commercial product or service.
Producers of BBC pages which maintain a list of non-BBC links should visit them from time to time to review and possibly refresh the mix and check that they are still working properly.
These guidelines also apply if the user chooses to open external links in a new browser window.
Links to other BBC pages
Guidelines on links between BBC public service and commercial pages can be found in Section 15: Interactivity - Navigation between BBC public service & commercial sites. See also Section 8: Harm and Offence online.
