Performance marketing agency drives 17% lift in repeat purchases with Faraday’s demographic enrichment

Marketing agencies today are in a bind.

Their brand clients expect clearer data, sharper predictions, and measurable ROI—but most agencies are working with the same third-party datasets as their competitors. That makes it hard to differentiate, hard to prove ROI, and harder still to retain high-value accounts.

Agencies that can’t surface unique, predictive insights risk looking like commodities in an industry where brands are paying for strategic advantage, not generic analytics.

The problem

One performance marketing agency faced this challenge firsthand. Their brand client’s repeat purchase rates had plateaued, and the team realized that their audience assumptions were largely untested.

They believed their “younger” online buyers were driving growth—but without deeper enrichment, they lacked visibility into who these customers actually were. Their internal dashboards showed the numbers, but not the people behind them.

The solution

Using Faraday’s demographic enrichment, the agency reshaped how their client understood its core audience. The enriched data revealed that what the brand assumed were “younger” online buyers were actually five to ten years older than expected.

Armed with this new demographic clarity, the agency refined welcome flows, personalized product recommendations, and built messaging that reflected the audience’s true profile and motivations.

The outcome

Within just five months, the client saw a 17% lift in repeat purchases compared to the same period the year before. Beyond the lift itself, these refinements strengthened customer lifetime value and gave the marketing team newfound confidence in their audience strategy.

“We always had these customer personas in our minds,” said the client’s marketing lead. “It was interesting to see how what we thought were younger online customers weren’t as young as we thought.”

By helping the agency uncover and act on these insights, Faraday enabled them to elevate from an execution partner to a strategic growth driver—delivering proprietary, data-backed understanding their competitors couldn’t match.

What does this mean to you?
