Facebook Lookalike Audiences are often touted as one of the most effective tools in any marketer's arsenal. But why do some campaigns see sky-high conversions while others barely break even? The answer lies in the way these audiences are built and optimized.
At LeadEnforce, we've analyzed over 15,000 Facebook ad campaigns across industries, and the data consistently points to one thing: the quality of your source audience is everything.
Why Most Lookalike Audiences Fail
Many advertisers make the mistake of creating Lookalike Audiences from too broad or poorly defined source groups. Facebook's algorithm can only do so much with bad input. If your source audience includes cold leads or unqualified traffic, the resulting Lookalike will mirror those flaws.
According to our research, Lookalike Audiences based on:
-
Page likes
-
Website visitors without conversion events
-
Email lists with low engagement
...result in 34% lower CTRs and 29% higher CPCs on average.
The LeadEnforce Approach: Quality Over Quantity
Lower lookalike similarity (1%) consistently cost less per lead — 70% cheaper than a 10% LAL
Instead of relying on basic Facebook data, LeadEnforce allows you to build Lookalike Audiences based on real user behavior from your competitors' communities and highly engaged public pages.
By targeting people who interact with specific Facebook pages, groups, and posts, you create a refined seed audience that's inherently more qualified. This is especially powerful for:
-
eCommerce brands targeting niche interests
-
Local service businesses
-
B2B companies aiming at decision-makers
Stat to know: Campaigns using LeadEnforce-generated Lookalike Audiences see a 51% improvement in ROAS compared to standard Facebook Lookalike methods.

-
Test audience sizes: Smaller Lookalikes (1%-3%) often yield better performance when paired with high-quality sources.
