Lookalike models are only as good as the seed audiences that train them. Feed a platform a list diluted by one-time buyers, serial returners, and duplicate anonymous purchases, and it learns to find more of exactly those people. The result is an acquisition engine optimized for churn. Building a gold-standard seed audience requires knowing who your truly high-value customers are across every channel and touchpoint, including the ones who checked out as guests, bought in-store, or exist under three different email addresses. Without that foundation, you’re not prospecting for your best customers. You’re just prospecting.
The Amperity Approach
Amperity helps you build the cleanest possible seed audience from your first-party data, so the algorithms you’re paying to optimize are actually learning from your best customers.
A seed list that reflects the whole customer, not just one touchpoint. Identity resolution merges fragmented data from POS, ecommerce, and loyalty systems into a single trusted profile, so your highest-value customers are actually in your seed audience rather than scattered across duplicate records.
Optimize for who a customer will become, not just who they’ve been. Out-of-the-box Predicted CLV goes beyond historical spend to identify who will be high-value, giving ad platforms a forward-looking signal that improves the quality of the customers they find.
Seed audiences that never go stale. Seed audiences refresh automatically as new high-value customers are identified and opt-outs are removed, keeping lookalike models current without manual intervention.
How to Get Started
Identify: Define your best customers using Predicted CLV models, such as the top 1 to 10% by predicted value, and Customer Value Migration analysis to confirm you are drawing from true loyalists.
Segment: Build a precise seed audience by filtering out one-time buyers, serial returners, and any other low-value signals that would dilute the model.
Onboard: Sync the seed audience directly to Meta, Google, TikTok, and The Trade Desk to train platform algorithms on the profile of your ideal customer.
Maintain: Refresh the seed audience automatically as new high-value customers emerge and opt-outs are removed, keeping models current without manual maintenance.
Measure: Track LTV and retention rates of new cohorts acquired through these campaigns versus generic prospecting. Prove the ROI. Repeat what works.
Better seed data means better customers. It really is that simple.
