The Creator Effectiveness Playbook Webinar

Creator marketing is booming. But what actually drives brand growth?

Launching at Cannes Lions, The Creator Effectiveness Playbook is the highly anticipated follow-up to The Long and the Short (Form) of It, now bringing together WPP, System1 and TikTok to explore how brands can close the gap between creator attention and long-term brand growth. Join Andrew Tindall, Chief Growth Officer at System1, and Josh Gornell, Vice President, Commercial Paid Social at WPP as they unpack the report’s findings and share practical guidance for more effective creator advertising.

Built from the analysis of hundreds of creator ads, the research reveals how different types of creators drive attention, emotion and branding, and how marketers can choose the right approach based on their objectives.

What you’ll learn

  • Why creator content captures attention but doesn’t always translate into brand growth
  • The creative characteristics that make creator advertising more effective
  • How different creator approaches impact attention, emotion and branding
  • What marketers can learn from the latest evidence-based research into creator effectiveness
