Ending Content on a Positive Emotional Peak Increases Purchase Intent by 11% and Awareness by 34%

Jul. 16, 2026

New research by Billion Dollar Boy, the social agency with Creator Instinct®, reveals that purchase intent increases by 11% and awareness increases by 34% when content ends on a peak of strong positive emotion in the final three seconds.

The finding comes from Creator Instinct®: Unlocking the Social Code, a new research report analysing 5,000 creator-led assets developed across the US and UK. The assets are assessed for four core performance drivers: engagement, view-through rate; brand favourability; purchase and consideration intent; and mapped against 39 emotional signals by DAIVID’s attention and emotion tracking technology.

The research results provide a blueprint for advertisers to drive intent and memorability on social. They suggest that the ending is where attention converts into outcome - whether audiences share, save or buy the product featured, or remember it. The results move the argument beyond social media’s “3-second rule,” which advises brands to frontload recognition, and highlights the urgent need for brands and creators to optimise for the final three seconds as much as the opening hook.

The report argues that the ending is not simply the wrap-up of the story, but the mechanism it has been building towards. When the final three seconds hold attention, organic engagement increases by 31% on Instagram. 

Emotional Timing Matters As Much As Emotional Intensity

The research also found that content that builds anticipation before delivering a satisfying payoff increases organic view rate by 110% across Instagram and TikTok combined - tripling to 318% on TikTok alone. It also increases engagement rate by 83% on TikTok. The findings suggest that emotional timing matters as much as emotional intensity. 

The report argues that creators instinctively build stories around a payoff. They successfully increase anticipation before rewarding viewer attention with a satisfying resolution - and only introduce the product benefit at the emotional zenith. Across categories, that payoff takes different forms: the transformation reveal in Beauty, the punchline in Entertainment, or the finished plate in Food and Drink. 

The research identifies several common techniques used by creators to successfully land a strong ending: 

• Build towards a satisfying payoff, whether that’s a reveal, the transformation, or reaction shot. 
• Design the final three seconds to peak, not taper off. 
• Build the asset backwards from the payoff. 

Case study: Pinterest Predicts

The research is supported by real-world campaign analysis, including Billion Dollar Boy's work with Pinterest. For Pinterest Predicts 2026 - Pinterest’s annual forecast of trends set to shape the year ahead - Billion Dollar Boy paired the platform with creators to bring each predicted trend to life.

For the “Wilderkind” trend, centered on animal-inspired aesthetics, creator Duncan Smith (@trashboy_nyc) upcycled an abandoned Wassily Chair using deer hide fabric. The video’s direction is deliberate: the finished chair is never shown until the final frame. The creator built anticipation, and kept the promise of revealing the final product at the end.

The campaign’s result: 93% of comments contained positive sentiment and the campaign achieved an engagement rate of 7%. 

Simon Harwood, Global Effectiveness Director, Billion Dollar Boy, commented: 

“The ‘peak-end rule’ dictates that our memory of an experience is determined by two moments - the most emotionally intense point and how it ultimately concludes. Our research shows that while the opening earns the view and the attention, the ending drives engagement, awareness and purchase intent.  The best creators instinctively know this. They build anticipation throughout the story, deliver a satisfying payoff and place the brand at the moment of the highest emotional impact. That’s a new framework that marketers can apply not only to creator partnerships, but across their own social content too. The final three seconds shouldn’t be treated as a soft sign-off. They're just as important for performance as the start.”

 

Duncan Smith, Creator, commented: 

“You have to make the payoff worth the wait. If you build curiosity at the start of a video but the ending doesn’t truly deliver, people won’t engage, remember it, or share it. The final reveal is the reward for the viewer investing their time, that’s the moment that sticks with them.”
