What are Facebook Lookalike Audiences?

Facebook Lookalike Audiences can be used to reach people who are similar to your current customers. They increase the probability of generating high-quality leads and offer more value on ad spend.

Lookalike Audiences are formed based on source audiences. You can create a source audience (also known as a seed audience) using data from:

  • Customer Information. A newsletter subscription list or a customer file list. You can either upload a .txt or .csv file, or copy and paste your information.
  • Website Visitors. To create a custom audience based on website visitors, you need to have Facebook pixel installed. With pixel, you create an audience of people who have visited your website, looked at a product page, completed a purchase, etc.
  • App activity. With active Facebook SDK event tracking, app administrators can collect data on the people who have installed your app. There are 14 pre-defined events that can be tracked such as, “added to the basket” for retails apps, or “level achieved” for game apps.
  • Engagement. An engagement audience is comprised of people who engaged with your content on Facebook or Instagram. Engagement events include: video, lead form, canvas and collection, Facebook page, Instagram business profile, and event.
  • Offline activity. You can create a list of people who interacted with your business in person, by phone, or another offline channel.

Multiple Lookalike Audiences can be used at the same time for the same ad campaign. You can also pair Lookalike Audiences with other ad targeting parameters, such as age and gender or interests and behaviors.

Find the right source audience and use these tips to reach new people on Facebook.

1. Use the right source audience for your goals

Different custom audiences match different goals.

For example, if your goal is to drive awareness of your business, a Lookalike Audience based on your Page Fans may be a good idea.

If your goal is to increase revene and ROAS, then a Lookalike Audience based on spenders will be a better choice.

2. Get creative with Custom Audiences

You can create custom audiences around a variety of parameters. Drill down on the options that best align with your campaign goals.

Ideas for Custom Audiences include:

ENGAGED:

  • XY+ quests achieved in the game (in last XY days/months)
  • XY+ times App launched in the last XY days/months
  • engaged with high LVL – e.g. all players with level 100
  • XYZ+ logins in 1 day – (in last XY days/months)
  • 1, 3, 5 or even 10% lookalikes

PAYERS: (later down the road)

  • top 250 payers (in certain month)
  • 2+ special offers bought (in last XY days/months)
  • XY soft currency bought (in last XY days/months)
  • 1+/3+/5+ payments in last XY days/months
  • whales
  • engaged payers – players with 10/20/30+ logins in last XY days & made a purchase
  • top 10% purchasers (in last XY days/months)
  • single pay over xy UDS (in last XY days/months) – single payment over 20, 30, xy USD

3. Test your Lookalike Audience size

Consider different audience sizes for different campaign goals.

Smaller audiences (1-5 on the scale) will most closely match your custom audience, whereas large audiences (6-10 on the scale) will increase your potential reach, but decrease the level of similarity with your custom audience. If you’re optimizing for similarity, aim for a smaller audience. For reach, go large.

4. Choose high-quality data

The better the data you provide, the better the results.

Facebook recommends between 1,000 and 50,000 people. But an audience of 500 loyal customers with always perform better than an audience of 50,000 good, bad, and average customers.

Avoid broad audiences like “all app installers.” These large audiences will include great customers along with those who bounce after a short time.

Hone in on the metrics that determine your best customers. Often these are further down the conversion or engagement funnel.

5. Keep your audience list up-to-date

If you’re providing your own customer information, make sure it’s as current as possible. If you’re creating a custom audience with Facebook data, add date range parameters.

For example, if you’re adding a custom audience based on purchases, you may only want to target those who have made a purchase in the last 30 to 90 days.

Refresh lookalikes often – at least once a quarter. If you have enough data, once a month.
