How to Create Lookalike Audiences in Sparkforge Ad Manager

By Sparkforge Support Team ·Last reviewed May 3, 2026

Lookalike audiences in Sparkforge Ad Manager find new prospects who match your existing customers. Pick a page or custom audience as the source, set country and size, and Facebook builds the match list.

A lookalike audience targets new people who behave like your existing customers. In Sparkforge Ad Manager, you build them from a Page or a Custom Audience, pick a country, set the size, and Facebook finds matches in 6 to 24 hours.

Where to find the option

You can create lookalike audiences from inside the campaign creation flow. In step 2, Budget and Audience, scroll to Audience Controls and find the Intended Audience section. Open the Lookalike Audience tab, click the dropdown, and pick Create a Lookalike Audience at the top of the list.

How a lookalike audience works

A lookalike uses an existing custom audience or Page as the source. Facebook then delivers the ad to people who resemble that source on the signals that matter — interests, behaviors, demographics. The closer the match, the smaller the audience; the broader, the larger.

Create the audience

Click Create a Lookalike Audience. A dialog opens with these fields:

Data source

  • Page — pick any Page connected to Ad Manager.
  • Custom Audiences — pick from the custom audiences already built in Ad Manager.

Audience name

Name it something you'll recognize later — for example, LAL — Repeat Customers — US.

Geographic location

Pick the country where you want Facebook to look for matches. Only countries are supported — no cities, neighborhoods, or provinces.

Audience size

Choose a range from 0 to 10 percent. 0–1% is the closest match — smaller but higher-quality. Increasing the percentage gives a larger, looser audience.

Click Create audience. The audience appears in the Lookalike dropdown but isn't ready until Facebook finishes processing.

Audience states

StateWhat it means
ReadyThe audience passed Facebook's checks and is usable in any campaign.
PopulatingFacebook is building the match list. Takes 6 to 24 hours. Once populated, audiences refresh every 3 to 7 days while in active use.
Audience not createdThe source audience was likely too small. Build a larger source and try again.

Audiences in Ready or Populating status can be selected for new campaigns.

Frequently Asked Questions

How long until a lookalike is ready?
Six to 24 hours. While building, the status shows Populating; once Facebook finishes, it switches to Ready.
What size should I pick?
0–1% is the tightest match and best for direct response. 2–5% widens reach with looser matching. 5–10% is broad and best for awareness campaigns.
Can I target by city instead of country?
No. Only country-level targeting is supported for the lookalike source location.
Why did I get an Audience not created status?
The source audience was too small for Facebook to find statistically meaningful matches. Use a larger custom audience or a high-traffic Page as the source.
How often does the audience refresh?
Every 3 to 7 days, as long as you're actively running ads against it.
