A custom audience on Facebook is an ad targeting strategy that allows you to get in touch with basically two kinds of people.

Let’s talk about the different types of custom audiences that you can create on Facebook.

Types of Custom Audiences on Facebook

One of the ways you can create custom audiences on Facebook is by uploading your existing customer/lead list.

But, why would anyone do that? Facebook allows you to market your brand in a unique and effective way. So, you want to leverage it to connect with your customers or prospects more effectively.

For instance, you can upload your email subscribers’ list to Facebook. Your subscribers are leads that have a good chance to become your customers down the road.

What Facebook does is that it finds your website visitors’ Facebook profiles with the information that it gathers on your website.

Using Your Facebook Custom Audiences

Once you have created your custom audience, Facebook will save it. So, you’ll be able to use it while creating an ad.

On the ad creation page, you can just select the custom audiences option and select an audience from the saved list.

There are many ways to utilize your custom audiences.

Remarketing

Remarketing allows you to keep in touch with the people that have interacted with your brand in the past.

For some reason, they didn’t take the action you wanted them to take. Remarketing is your chance to be more creative and get them to act on your offers.

For instance, prospects that added your product in their carts but left your online store without purchasing it.

You can create a custom audience of those visitors and retarget them with a persuading message.

Targeting Existing Customers

You can also use custom audiences to convert your one-time customers into repeat customers. Just upload the list of your existing customers and let them know about your amazing products.

Depending on your product and customer service, if they are happy with your business, there is a high chance they’ll buy again.

Increasing Your Facebook Audience

Social media is a great way to connect with your existing customers and attract new ones. To build your Facebook audience, create a custom audience around your customer list or website visitors and advertise your page to them.

Facebook Custom Audiences Lookalike

Lookalike audiences are a powerful way to find more prospects on Facebook and connect with them. A lookalike audience is a group of people that are similar to your customers or prospects.

This means, they might not have interacted with your business, but there is a high chance they’d be interested in your business.

This helps you if you have a small list of prospects and want to let more people know about your products.

Facebook Custom Audiences Minimum Size

From a technical standpoint, you just need 100 people in your Facebook custom audience to be able to show ads to them.

However, Facebook recommends going with at least a few hundred users, which seems to be the right way to go.

So, to be on the safe side, consider keeping your custom audience to 1000.

Using Facebook Audience Insights

Facebook audience insights can provide actionable information about your custom audiences. Using these insights, you can leverage the demographics data to reach more prospects on the platform.

And, whenever someone new interacts with your Facebook page or ads, they become your engagement custom audience.

You can find Facebook audience insights by going to the ads manager > Tools > Audience Insights.

Final Thoughts

You can also create lookalike audiences using this feature. This allows you to target people similar to your prospects or customers.

Moreover, the size of your custom audience can be 100 at the minimum. However, the limit might not apply to all campaigns. And, it’s a good idea to have at least a few hundred people in your audience.
