Should You be Using Lookalike Audiences?

Do you want to sell more while spending less? Of course, the answer is yes! Lookalike audiences are Facebook generated audiences that have incredibly high conversion rates. If you want to drastically increase ROI on all your Facebook ad campaigns, then utilizing lookalike audiences is going to be a huge game changer.

What are Lookalike Audiences?

Using audience data that you provide, Facebook will create an audience that closely matches yours, to target with Facebook Ads. The audiences that are generated by Facebook are called lookalike audiences. Lookalike audiences consist of Facebook users that are similar or “look like” your audience. Facebook is able to draw connections using their vast amount of user data.

The purpose of a lookalike audience is to reach users that have never been exposed to your brand/business, in order to build brand awareness and authority. Thus, spending on Facebook ads is done more efficiently with a higher ROI. Instead of wasting money trying to figure out which custom audience works best, your lookalike audience will prove to be drastically more receptive to your ads.

The reason conversion rates for lookalike audiences are so high is that the data used to generate them was pulled from your Facebook Pixel. Which means Facebook is constructing audiences based on successful website views or events. Bringing higher conversion rates for your Facebook ads.

How to Build a Lookalike Audience?

If you have just started using Ads Manager or the Facebook Pixel, then there will not be enough website data to draw similarities. When it comes to building your lookalike audience it is imperative to send quality traffic to your website. Generally, Facebook recommends a source audience with between 1,000 to 50,000 people, where source quality matters. Facebook uses pixel data to create audiences. Thus, initial high-quality traffic will lead to higher quality lookalike audiences.

Here are some additional bits of information from Facebook to consider when creating Lookalike Audiences.

  • Your Lookalike Audience will only include people from the country/countries you select during creation.
  • Your source audience must contain at least 100 people from a single country in order for us to use it as the basis for a Lookalike Audience.
  • You can create up to 500 Lookalike Audiences from a single source audience.
  • People in your source audience will be excluded from your Lookalike Audience unless you use a pixel as your source audience.
  • You can use multiple Lookalike Audiences at the same time for a single ad set. The ad set will target your ads to people who are in any of the selected Lookalike Audiences.
