    Case Study

    Jewelry Subscription Brand

    A fast-growing jewelry subscription brand needed to bring down its cost per purchase and turn cold traffic into paying subscribers, backed by real tracking instead of guesswork.

    Growth Levers We Pulled

    Full-Funnel Tracking

    UTM tags, Meta Pixel, and GA4 wired together so every purchase can be traced back to its ad.

    Funnel Audit & Roadmap

    A full audit of ads, landing pages, and analytics turned into a clear 30/60/90-day plan.

    Creative Refresh

    Story-driven video ads and social-proof creative built specifically to convert cold traffic.

    Smart Targeting

    High-intent lookalikes layered with retargeting to keep cost per purchase under control.

    Overview

    Growth Without a Clear Read on ROI

    The client was already spending on paid ads, but the results were inconsistent. Cost per purchase kept climbing as competition in the jewelry subscription space grew, and the account had no meaningful audience segmentation to fall back on. Creative built for a broad audience simply was not landing with cold traffic anymore.

    On top of that, there was no unified tracking setup, which meant the team was making budget decisions without knowing which campaigns were actually driving purchases. HK Tech Hub was brought in to fix the measurement problem first, then rebuild targeting, creative, and the landing experience around what the data showed.

    The Challenge

    The Challenges We Solved

    Rising Cost Per Purchase

    Growing competition in the jewelry subscription space kept pushing auction prices up, eating into margins on every sale.

    No Audience Segmentation

    Every visitor was treated the same, so creative built for a broad audience never connected with genuinely cold traffic.

    No Unified Tracking

    Without UTM tags or connected pixels, the team could not tell which campaigns were actually driving real purchases.

    The Strategy

    Why It Worked

    Paid acquisition only scales when every dollar can be traced back to a result. Every part of the strategy was built around that principle.

    Tracking

    Measurement Came First

    Fixing UTM, Pixel, and GA4 tracking before touching a single campaign meant every later decision was based on real numbers.

    Creative

    Creative Built for Cold Traffic

    Story-driven video and social proof gave strangers a reason to trust the brand before they ever saw a price.

    Targeting

    Precision Over Reach

    Lookalike and retargeting layers focused spend on people who actually looked like existing subscribers.

    Conversion

    A Checkout That Didn't Lose People

    Clearer trust signals and a smoother mobile checkout kept interested buyers from dropping off at the last step.
