The Handbook is developing effective counter-narratives to the proliferation of online violent extremist content. It defines a counter-narrative as a message that offers a positive alternative to extremist propaganda, or alternatively aims to deconstruct or delegitimise extremist narratives through providing help in the main stages of creating, launching, and evaluating an effective counter-narrative campaign.

The detailed step-by-step guide focuses on civil society, youth or NGO-led online counter-narratives campaigns. The guide is divided in the following sections, offering case studies to each step: planning a campaign, creating content, running a campaign, online advertising, engaging audiences, and evaluating campaigns. It is intended to be a beginner’s guide to help anyone looking to proactively respond to extremist propaganda with counter-narrative campaigns. Furthermore, the handbook offers more information through a link to a counter-narrative toolkit and additional resources.
