Case Study: Symprove achieves 58% more conversions and 78% more efficient CPMs with Quantcast's cookieless solution

Symprove unlocks new customer growth with Quantcast’s cookieless solution

Symprove is a digitally native probiotic brand that sells its supplement exclusively online and was looking to expand programmatic reach to boost new customer acquisition. With browsers like Safari and Firefox (about 37% UK share) having deprecated third‑party cookies, large swaths of prospects were previously inaccessible, creating a challenge for scalable, measurable prospecting.

Symprove chose the Quantcast Platform over DV360 for its performance and ease of use, then adopted Quantcast’s cookieless activation and measurement to prospect in previously blocked environments. The cookieless approach delivered a 58% increase in conversions and a 78% more efficient CPM, was simple to deploy, and provided cookieless reporting that Symprove integrated into its always‑on marketing strategy.
