Meta Ads Custom Audiences Guide: High-Value Lookalikes

"Lookalikes are dead." We hear this every week. It is false. Bad Lookalikes are dead. If you build a Lookalike based on "Website Visitors (30 Days)," you are telling Facebook: "Find me more window shoppers." To scale, you need to tell Facebook: "Find me more people who spend $100+."
The Hierarchy of Custom Audiences
Not all data is equal.
- Platinum: Customer List with LTV (Lifetime Value).
- Gold: Pixel Purchase Events (Last 180 Days).
- Silver: Add to Cart / Initiate Checkout.
- Bronze: Instagram Engagers / Video Viewers (3s).
- Trash: Website Visitors (All).
Strategy 1: The LTV Lookalike
This is the most powerful audience you can build.
- Export CSV from Shopify/WooCommerce: Include "Email", "Phone", and "Total Spent."
- Format: Facebook requires a specific format. Use a "Value" column.
- Upload: Go to Audiences → Create Custom Audience → Customer List.
- Select "Customer Value": This tells Facebook who the whales are.
- Create Lookalike: Start with 1%.
- Logic: Facebook will look for users with similar spending habits and credit card activity.
Strategy 2: The "Frequency" Lookalike
You don't just want one-time buyers. You want loyalists.
- Filter your CSV: Keep only customers who have bought 2+ times.
- Upload: Create a "Repeat Purchasers" Custom Audience.
- Create Lookalike: 1%, 3%, and 5%.
- Why: This finds users who are prone to brand loyalty, not just deal seekers.
The Most Important Audience: Exclusions
You waste 20% of your budget retargeting people who just bought. Always exclude:
- Purchasers (30 Days).
- Purchasers (180 Days) - unless you sell consumable products (coffee, shampoo).
- Pro Tip: Exclude "Job Seekers" if you are hiring. (Create a custom audience of people who visited your /careers page).
Dynamic Syncing (Klaviyo/HubSpot)
Manual uploads are outdated. Use a connector (Klaviyo, HubSpot, Zapier) to sync your segments dynamically.
- Scenario: A user buys a product.
- Action: Klaviyo adds them to "VIP Customers" list.
- Sync: Meta automatically updates the Custom Audience.
- Result: The Lookalike gets smarter in real-time.
Summary
Broad targeting (no audiences) is great for account simplification. But Lookalikes are your Signal Booster. When you launch a new ad set, give the algorithm a hint. "Don't just find humans. Find lookalikes of these high-rollers."
