Religion is an area in which marketers should take particular care to avoid causing serious or widespread offence with their marketing communications. This Advertising Guidance explains how advertisers might avoid causing offence on the grounds of religion bearing in mind the differences between religious groups and what each may, or may not, find offensive. Advertisers need to be mindful of religious sensitivities, which can be a challenge in a diverse multi-faith (or no faith) and multi-cultural society such as the UK, and this guidance outlines where the ASA has previously drawn the line as well as some aspects of religion that it would be best to avoid in your marketing communications.
