Brand Keys measures brands – and how loyal their customers are to them, because loyalty matters.
We’ve done it for more than 40 years. Measuring emotional and rational values and actual consumer expectations that govern customer loyalty. Things that drive in-market behavior and real-world sales and brand profitability. We have independent validations from leading professional organizations like The Advertising Research Foundation, the Association of National Advertisers, and the American Marketing Association to prove it. Why measure it? Well, loyalty matters.
Yeah, I know, kind of an intuitive statement, huh? A head-nodder. Something you believe in your gut. It just feels right, right? So, sure, loyalty should matter. Everyone says so. And having said that, I think it’s also fair to say, few grasp just how much it matters. Today it’s more than a marketing buzzword or points to collect. It’s the connective tissue between brand and behavior, promises and performance.
It’s also what Brand Keys does professionally, but it’s also our passion. Because loyalty matters. It’s the absolute best leading indicator available. Loyalty scales trust, sustains value, and signals what comes next. In a marketplace overloaded with noise and novelty, loyalty touches virtually every dimension of your life.
Philosophically, it anchors values and identity. Personally, it offers belonging, meaning, and emotionality, shaping how we define ourselves. Socially, it builds trust, cohesion, and community. And of course, economically, loyalty drives repeat behavior for brands, lowers acquisition costs, and fuels long-term value. So, loyalty isn’t just a trait – it’s a force multiplier in human behavior and business profitability. That’s why we’ve conducted our Customer Loyalty Engagement Index (CLEI) annually for the past 28 years.
Our loyalty metrics predict repeat purchase, advocacy, and resistance to competitive offers, and profits. It’s the most versatile, cross-functional, predictive metric you can find. This year we interviewed 80,000+ consumers to assess 1,104 brands in 114 categories. Some brands that consumers assessed #1 when it comes to loyalty included the NFL, Discover Financial, Hyundai, Amazon, Lego, Samsung, Modelo, Dunkin’, ChatGPT, and Netflix. You can find a complete list of 2026 categories and brand loyalty champions at the CLEI link above.
Brand remains the foundation of modern marketing – shaping everything from strategy to storytelling. In a world oversaturated with logos and 24/7 social networking, brands have arguably become victims of their own success. Once the cornerstone of corporate value, brand and the metrics that tracked them were treated as strategic assets, key to differentiation and long-term loyalty.
Today, however, brands have become ubiquitous, familiar, and easily ignored. Alas, so have the metrics designed to quantify them. And attention, unfortunately, has shifted. Social media, the obsession with likes and shares and Net Promoter Scores, awareness and satisfaction levels, the scramble for real time performance dashboards, and a fixation on increasingly fragmented media planning have sidelined the long game of trust, meaning, differentiation and emotionality. And ultimately profitability. What with corporations increasingly shifting focus away from traditional brand stewardship and loyalty in favor of speed, scale, social, media models, and short-term performance indicators.
Brand saturation has crowded out authentic brand management. In most developed markets, the average consumer can name dozens of brands across categories without much effort. Apple, Coca-Cola, Nike, McDonald’s, Amazon, Disney – these are household names. But so what? Branding still matters, but mere awareness is table stakes rather than a competitive edge. Increasingly, consumers encounter brands through algorithms, not emotional engagement – experiences that legacy metrics like awareness, NPS, or simple favorability scores can’t capture. They really can’t!
Brands must find new ways to stay relevant, because incremental optimization no longer cuts it. In this environment, success is measured in click-through rates, conversions, and ROAS, not brand lift. And that shift has eroded the value of traditional brand metrics, which rely on longer time horizons. Culture is at play too. Younger consumers view brands with more skepticism and cynicism. They expect transparency, sustainability, and values alignment, and switch allegiances when a brand falls short. Companies can no longer rely on image alone – they must continuously earn relevance, not just awareness.
And yet, amid all this noise, real loyalty – earned, not assumed, and actually measurable – has become more valuable than ever. Over the past 30 years, as traditional meaning and import of brand has eroded and consumer attention has fragmented, enduring loyalty has emerged as one of the few sustainable brand differentiators. Not “loyalty” based on habit or inertia, but loyalty rooted in consistent experience, emotional engagement, and brand values aligned with those of the customer. In this landscape, loyalty is no longer a byproduct of branding – it’s the destination.
Because in the end, it’s not the brand that defines the customer – it’s the loyalty the customer chooses to give that ultimately defines the brand.
So, yeah. Loyalty matters.
