    Improving higher ROAS through cross-sell audience strategy

    A major retailer improved paid media efficiency by identifying high-value customer segments and testing a sharper cross-sell strategy.

    This work was completed during a previous role in a platform or agency team. It is not presented as an Ironpath client engagement.

    The Challenge

    Stagnant growth, hidden demand

    Organic growth had slowed, and standard retargeting was not enough to unlock the next layer of revenue. The opportunity was to find existing customers with strong buying signals in adjacent categories and test whether paid media could move them into fashion.

    The Strategy

    From generic retargeting to audience-led growth

    Customer Analysis

    Used basket analysis to identify high-value, multi-category shoppers with a higher likelihood of converting.

    Audience Build

    Isolated frequent customers active in one category but underexposed to the fashion offer.

    Controlled Test

    Compared standard retargeting against the custom cross-sell audience to measure efficiency and revenue impact.

    The Results

    A cross-sell playbook adopted at scale

    $6.05 ROAS. Delivered across the tested category.
    $17 CPO. Compared with $19 for standard tactics.
    26% above benchmark. Vs. the business's continuity retargeting baseline.
    Adopted broadly. The finding became a permanent cross-sell playbook across paid social and programmatic.

    "Efficient growth is not always about finding brand-new customers. Sometimes the best opportunity is already inside your customer base. you just need better audience strategy to find it."
