What is Lookalike Audience?
Lookalike Audience
Definition, formula, India benchmarks, and the operator-grade nuance behind it.
Lookalike Audience is a Meta or Google audience targeting feature that finds new users similar to a seed audience (e.g., existing customers, high-value users). The seed audience defines the pattern; the platform expands to similar profiles within a defined size percentage (1%, 5%, 10% of country).
Lookalike Audiences expand seed → similar new audiences.
Tighter LAL (1%) = higher quality, lower volume; looser (10%) = lower quality, higher volume.
Best seed: 1,000+ recent high-LTV customers, not generic email list.
Lookalike Audiences are built by selecting a seed audience (existing customers or high-value users) and a similarity tier (1%, 5%, or 10% of population). The platform algorithm finds users matching the seed pattern.
Lookalike = Seed Audience × Similarity Tier (1% to 10%)The operator's read on Lookalike Audience
Lookalike audiences work only if the seed is high-quality. Common mistake: seeding off generic email-list with mixed-quality contacts. Best seed = top 20% AOV or top-LTV cohort customers from the last 90 days. Use 1% LAL for quality (smaller, sharper); 5–10% for volume after 1% saturates. Refresh seed monthly — stale seeds train on old patterns.
