In the rapidly shifting consumer landscape of sub-Saharan Africa, where younger shoppers have grown fluent in the language of skincare science, Colgate-Palmolive found that the old art of casting wide nets had given way to something more precise. Within sixty days of rebuilding their digital strategy around AI-driven intent signals, their Sanex brand in South Africa achieved results that reframe what marketing efficiency can mean. The deeper story is not one of technology displacing human judgment, but of technology creating the conditions under which human judgment finally has room to breathe
Colgate-Palmolive's AI-Powered Search Strategy Drives 44X Conversion Spike in South Africa
They let AI do the heavy lifting so they could focus on what machines couldn't do.

What made the skincare analysis test so effective compared to a traditional product page?
Mimi
It reframed the entire interaction. Instead of asking people to buy, it asked them to learn about themselves. That's a fundamentally different conversation—one where the company becomes a guide rather than a salesperson. People were willing to engage because they got something valuable back.
Mark
Why did AI Max specifically matter here? Couldn't they have just written better keywords themselves?
Mimi
They could have, but they would have missed things. AI Max found patterns in how people actually search—the conversational, exploratory queries that humans might dismiss as too vague. It caught people at stages of the journey that traditional keyword research often overlooks.
Mark
The 44X conversion increase seems almost too clean. What's actually happening under that number?
Mimi
It's not magic. It's specificity meeting intent at scale. They went from showing ads to broad audiences and hoping some converted, to showing the right message to people already signaling interest. The denominator didn't change much—they're just converting a much higher percentage of the traffic they're getting.
Mark
Why does the company think this will work in Kenya and Nigeria?
Mimi
Because the underlying behavior is the same. Gen Z and Millennials across Africa are digitally native, ingredient-conscious shoppers. The infrastructure and consumer mindset that made this work in South Africa exists in those markets too. The execution might need tweaking, but the principle travels.
Mark
What's the risk of scaling this too fast?
Mimi
Ad fatigue, for one. If you're running the same omnichannel loop everywhere, audiences see the same creative across too many touchpoints. But they've already thought about that—they're letting AI manage the rotation and freshness. The bigger risk is assuming every market has the same search behavior and willingness to engage with a skincare quiz.
El Pulso
- Sanex, once a trusted functional brand, was quietly losing relevance as Gen Z and Millennial consumers began demanding personalized skincare guidance rather than generic product pitches.
- The team's answer was not a louder campaign but a smarter one — an online skin analysis tool that met curious shoppers at the precise moment of their questions, turning a sales funnel into a consultation.
- Google's AI Max was deployed to map high-intent search behavior across every stage of the consumer journey, while Demand Gen and Performance Max campaigns worked simultaneously at the top and bottom of the funnel.
- Within 60 days, conversions multiplied 44-fold and cost per click collapsed by 97 percent — not through volume, but through the disciplined pursuit of intent over impression.
- Emboldened by South Africa's results, Colgate-Palmolive is now extending the same framework to Colgate Optic White and preparing market entries in Kenya and Nigeria.
In the rapidly shifting consumer landscape of sub-Saharan Africa, where younger shoppers have grown fluent in the language of skincare science, Colgate-Palmolive found that the old art of casting wide nets had given way to something more precise. Within sixty days of rebuilding their digital strategy around AI-driven intent signals, their Sanex brand in South Africa achieved results that reframe what marketing efficiency can mean. The deeper story is not one of technology displacing human judgment, but of technology creating the conditions under which human judgment finally has room to breathe.
Lisa Mains-Sheard leads digital transformation for Colgate-Palmolive across sub-Saharan Africa, and the pressure she faced was familiar to anyone navigating legacy brands in fast-moving markets. In South Africa, Gen Z and Millennial consumers had become sophisticated skincare shoppers — researching ingredients, seeking personalized answers, expecting brands to meet them with knowledge rather than slogans. Sanex, long positioned as a functional body wash, was falling behind.
The team's response was to stop selling and start consulting. They built an online skincare analysis tool that helped users identify their skin type and find suited products — not a storefront, but a guided experience designed to meet people at the height of their curiosity. Around that tool, they rebuilt their entire search strategy using Google's AI Max, which identified high-intent queries at every stage of the customer journey: people seeking skincare advice, researching specific brands, or hunting for solutions to particular skin concerns. The approach was surgical where the old one had been broad.
They also constructed a full-funnel architecture working in two directions at once. Demand Gen campaigns built awareness through Gmail, YouTube, and display placements, drawing in new audiences. Performance Max campaigns with value-based bidding captured those already ready to convert. The AI managed optimization; the human team focused on creative work, storytelling, and brand positioning — the things machines cannot do.
The results were striking. Within sixty days, conversions rose 44-fold and cost per click fell by 97 percent. The explanation is less mysterious than the numbers suggest: the company stopped chasing volume and started chasing intent, letting AI handle audience matching so that human energy could flow toward better creative and smarter allocation.
Colgate-Palmolive is now scaling the framework to premium brands like Colgate Optic White and preparing to expand into Kenya and Nigeria. The broader lesson embedded in the campaign is one about the relationship between tools and strategy — AI did not replace the thinking; it created the conditions under which better thinking became possible.
Lisa Mains-Sheard runs digital transformation for Colgate-Palmolive across sub-Saharan Africa, tasked with making the company's marketing work harder. In South Africa, where Gen Z and Millennial consumers have become sophisticated shoppers—armed with knowledge of skin ingredients and searching for personalized solutions—the company's legacy brands like Sanex were losing ground. The market was moving fast, and the old playbook wasn't working anymore.
The challenge was clear: Sanex had been positioned as a functional body wash, but the market had evolved. Younger shoppers wanted more. They wanted guidance, education, answers to specific questions about their skin. So the company built something different—an online skincare analysis tool that let people discover their skin type and find products suited to them. It wasn't a sales page. It was a consultation. And it worked because it met people where their curiosity was highest.
To capitalize on that intent, Mains-Sheard's team rebuilt their entire search strategy around AI. They used Google's AI Max to rethink keyword optimization, letting the system identify high-intent queries at every stage of the customer journey—people asking for skincare advice, searching for specific brands, looking for dermatologists, hunting for solutions to particular skin problems. The old approach would have cast a wider net and hoped. This one was surgical. It found people already showing interest through their search behavior and purchase history.
But keywords were only half the equation. The team layered in a full-funnel strategy that worked in two directions at once. Demand Gen campaigns pulled in fresh audiences at the top of the funnel through Gmail, YouTube, and display ads on sites they visited regularly, building awareness and consideration. Meanwhile, Performance Max campaigns with value-based bidding captured ready-to-buy customers at the bottom. The AI handled the optimization; the team focused on what machines couldn't do—creative work, storytelling, brand positioning.
The results arrived fast. Within 60 days, conversions jumped 44-fold. The cost per click dropped 97 percent. Those numbers sound almost impossible until you understand what actually happened: the company stopped chasing volume and started chasing intent. They let AI do the heavy lifting on audience matching and bid optimization, which freed them to invest in better creative and smarter media allocation.
The success in South Africa has already triggered expansion plans. Colgate-Palmolive is now scaling the same framework across premium brands like Colgate Optic White. They're also preparing to launch it in Kenya and Nigeria, betting that what worked in one market can work in others. The real lesson isn't about the numbers—it's about what happens when you stop thinking of AI as a replacement for strategy and start thinking of it as a tool that lets you do strategy better.
