Brands today face increasing challenges in engaging their audience and maximizing return on ad spend (ROAS). If you’ve been trying to cut through the noise and stand out, you’re not alone. One highly effective strategy that many leading brands, including Coca-Cola, have adopted is leveraging User-Generated Content (UGC) in their advertising campaigns. Coca-Cola, a global leader in the beverage industry, saw impressive results by incorporating UGC ads into its marketing approach, doubling its ROAS in the process.
In this case study, we’ll explain how Coca-Cola used UGC ads to increase engagement, drive sales, and boost brand loyalty. The key to their success was tapping into psychological drivers like trust and relatability, which ultimately transformed their marketing strategy and delivered significant financial and brand-building outcomes.
Brand Overview!

Brand Name and Industry
Coca-Cola is a household name in the global beverage industry. Known for its iconic product, Coca-Cola, the brand offers a wide range of soft drinks and operates in the highly competitive consumer goods sector, specifically in the non-alcoholic beverage industry.
Target Audience
Coca-Cola’s target audience spans a wide demographic young adults, families, and middle-aged consumers. The brand’s appeal transcends borders, with its products being popular worldwide. Coca-Cola reaches individuals of different ages, ethnicities, and lifestyles, particularly those who seek refreshing, social, and indulgent experiences. Their customer base is diverse and dynamic, offering unique opportunities to engage with a variety of audience segments.
Marketing Objectives
Before introducing UGC ads, Coca-Cola focused on increasing brand awareness, engaging with younger consumers, and boosting product sales. While traditional advertising methods like TV and print were still in use, Coca-Cola recognized the importance of adapting to a more digital world where authenticity and consumer engagement were key.
Previous Ad Spend
Before implementing UGC ads, Coca-Cola had a history of high-budget ad campaigns, mainly on TV and through global marketing initiatives. While these traditional ads reached a broad audience, they lacked the engagement and authenticity that UGC ads offered, often falling short in creating personal connections with consumers.
Customer Retention Rate
Coca-Cola maintained a solid customer retention rate but sought to improve long-term customer loyalty. They recognized that engaging customers in more meaningful, interactive ways would help build stronger brand relationships. UGC ads became the perfect tool for achieving this, creating a sense of community and shared experience around the Coca-Cola brand.
UGC Ads Strategy!
UGC Format
Coca-Cola used a variety of UGC in their campaigns, including customer reviews, photos, videos, and social media posts. The main focus, however, was on customer-generated photos and videos. These showcased Coca-Cola products in real-life scenarios, friends enjoying a Coke at a party or families sharing a Coke during a BBQ. Such authentic, relatable moments helped foster a deeper emotional connection with the audience.
Content Source
The content was primarily sourced from Coca-Cola’s customers and influencers, who were encouraged to share their personal experiences. By leveraging user-generated posts on platforms like Instagram, TikTok, and X, Coca-Cola tapped into content that was already being shared by fans, turning it into powerful advertising.
Engagement Rate
After incorporating UGC ads, Coca-Cola saw a remarkable increase in engagement. Fans and consumers actively participated by sharing their photos and videos, leading to a surge in likes, comments, and shares. This organic engagement made Coca-Cola’s ads feel more like genuine recommendations from peers, rather than traditional, one-sided advertisements.
Quality of Content
Coca-Cola’s UGC content varied in quality, from raw, unpolished user photos to more professionally shot content. However, the most impactful UGC was content that felt genuine and authentic. These pieces, showcasing real-life moments of happiness, friendship, and social connection, resonated deeply with consumers and aligned perfectly with Coca-Cola’s brand message.
Call to Action (CTA)

Targeting Strategy
Coca-Cola focused on engaging young adults, particularly Gen Z and Millennials, two groups known for their high social media usage and preference for authentic, relatable content. By analyzing user behavior and social media trends, Coca-Cola ensured its UGC ads reached the most relevant and engaged audience.
