Privacy regulations and the systematic deprecation of third-party signals have permanently eroded the targeting infrastructure performance marketing was built on. Inside walled gardens like Meta and Tiktok, algorithms that once thrived on rich behavioral data are now operating with a fraction of the signal they need. This is driving CPAs up and audience quality down. For healthcare brands like HerMD, strict data privacy policies around women's health compounded the problem further.
Strategy inverted the conventional playbook: instead of working around the walled gardens or solely relying on the walled garden, we fed them. Achieved by establishing a strong first-party data foundation. CRM lists were onboarded directly into platform audiences, and Conversion API (CAPI) was implemented to restore server-side signal that browser-based tracking had lost — closing the attribution gap at the source.
We solved the cold-start problem from the outside in. Using a programmatic DSP and trusted third party audience data, we ran highly engaging ads against people who matched HerMD's ideal patient profile but hadn't yet entered the walled garden ecosystem. When those users clicked through, they carried behavioral intent signals into Meta and TikTok — giving the algorithms warm, qualified data points to learn from and expand on.
