What to Do When Lookalikes Stop Performing

Lookalike audiences used to be a reliable way to scale campaigns. But over time, many advertisers notice that performance drops. Why?

1. Audience saturation. The same people get targeted repeatedly, which drives up frequency and lowers engagement.

2. Weaker data signals. If your seed audience is too broad or outdated, Facebook may build less relevant lookalikes.

3. Privacy changes. Updates like iOS 14 have reduced the amount of trackable data, making lookalike modeling less precise.

A Meta report found that CPMs (cost per thousand impressions) increased by nearly 61% from 2020 to 2022, and advertisers relying heavily on lookalikes felt the impact strongly.

How to Fix Lookalike Audience Fatigue

1. Refresh Your Seed Data

Your lookalike is only as strong as the source. Update your seed audience with recent high-value customers. For example, instead of using all website visitors, focus on those who purchased within the last 60 days. This creates fresher and more accurate lookalikes.

2. Layer Interests and Behaviors

Don’t rely on lookalikes alone. Add interest- or behavior-based targeting to narrow down the audience. For instance, if you’re targeting B2B buyers, combine a lookalike with interests like “business software” or “entrepreneurship.”

3. Experiment with Audience Sizes

Smaller lookalikes (1%) are precise but can saturate quickly. Larger ones (5–10%) reach more people but with less accuracy. Test multiple ranges and monitor CPM, CTR, and ROAS. Often, a 2–3% lookalike balanced with interest filters works better than sticking to the standard 1%.

4. Rotate Creatives Frequently

Even the best audience won’t respond if the ads go stale. According to AdEspresso, ad fatigue can appear after just 5–7 impressions per user. Refresh creatives every two weeks or test multiple ad variations to keep engagement high.

5. Diversify Beyond Lookalikes

Don’t let your entire strategy depend on one method. Use custom audiences, retargeting, and interest-based targeting alongside lookalikes. For example, combine custom lists with interest targeting to build more resilient campaigns.
