A custom audience is a group of users defined based on specific characteristics or behaviors. Instead of using broad demographic targeting, custom audiences allow advertisers to target individuals who have already interacted with their brand in some way. This can include people who have visited a website, engaged with content, or are part of an existing customer base.

Custom audiences are often created using first-party data—information collected directly from users, such as email lists, phone numbers, or website activity. This makes custom audience targeting highly relevant, as marketers can reach out to people who have already expressed interest in their business.

By using custom audiences, advertisers can focus their efforts on those who are already familiar with their brand, increasing the likelihood of conversions and improving campaign performance.

Why Are Custom Audiences Important?

Custom audiences play a crucial role in helping marketers maximize PPC campaign performance. Here’s why:

Improved Targeting Accuracy

With custom audiences, advertisers can focus their advertising budget on people who have already interacted with their brand. This means not wasting money on broad, generic audiences that may not be interested in their products or services. Custom audience targeting leads to higher-quality leads and more efficient use of ad spend.

Higher Conversion Rates

People who are familiar with a business are more likely to convert. A custom audience allows brands to reconnect with users who have previously shown interest, making it easier to drive conversions. Whether they’ve visited a website, engaged with social media posts, or signed up for an email list, these individuals are already aware of the brand and may just need a little nudge to complete a purchase.

Better Ad Relevance

Since custom audiences consist of people who have already engaged with a brand, the ads shown to them are likely to be more relevant. When users see ads that align with their past interactions or interests, they’re more likely to engage, leading to higher click-through rates (CTR) and improved campaign performance.

Cost Efficiency

Custom audiences help make the most of an advertiser’s budget by targeting users who are more likely to take action. This leads to a better return on investment (ROI), as they will spend less money reaching unqualified prospects and more on potential customers who are ready to convert.

How to Create a Custom Audience

Creating a custom audience involves gathering data from existing users and uploading it to the advertising platform. Here’s how you can set up a custom audience on popular platforms like Meta Ads and Google Ads.

1. Meta Custom Audiences

On Meta, creating a custom audience is straightforward. The platform allows you to create audiences based on various sources, including:

• Customer Lists: Upload a list of email addresses or phone numbers.
• Website Visitors: Use the Meta Pixel to create audiences of users who have visited your website.
• App Activity: Target people who have engaged with your app.
• Engagement: Target users who have interacted with your posts, videos, or ads on Facebook and Instagram.

To create a custom audience on Facebook:

1. Go to the Meta Ads Manager and click on “Audiences.”
2. Click “Create Audience” and select “Custom Audience.”
3. Choose your data source (e.g., customer list, website visitors, or engagement).
4. Follow the instructions to upload your data or set up the audience based on your chosen criteria.

2. Google Ads Custom Audiences

On Google Ads, custom audiences (previously known as custom intent and custom affinity audiences) allow advertisers to target users based on their search behavior, interests, or website activity. There are two main ways to create a custom audience on Google Ads:

• Customer Match: Upload a list of user data such as email addresses or phone numbers.
• Website Visitors: Use Google’s remarketing feature to target users who have visited your website.

To create a custom audience on Google Ads:

1. Open Google Ads and go to the Audience Manager.
2. Click “Create Audience” and select “Custom Audience.”
3. Define your audience by entering relevant keywords, URLs, or apps that align with the behaviors and interests of your target users.
4. Set your campaign to target the custom audience you’ve created.

Best Practices for Using Custom Audiences

To make the most of your custom audiences, follow these best practices:

1. Segment Your Audience

Not all customers are the same. Segment your custom audiences based on user behavior, interests, or purchase history. For example, you can create separate audiences for users who have abandoned their carts, those who have made previous purchases, or those who have simply browsed your website. By segmenting your audience, you can tailor your messaging and deliver more relevant ads to each group.

2. Use Lookalike Audiences

Once you’ve created a custom audience, you can use it to create a lookalike audience. Lookalike audiences allow you to reach new users who share similar characteristics with your existing audience, expanding your reach while still targeting people who are likely to be interested in your business.

3. Personalize Your Ads

Custom audiences allow you to tailor your ad messaging to specific groups of users. For example, you can show personalized ads to customers who have previously purchased from your site, offering them a discount on their next purchase. Personalization makes your ads more relevant and increases the chances of conversions.

4. Regularly Update Your Audience

Custom audiences work best when they’re kept up to date. Regularly update your audience lists by removing inactive users and adding new ones to keep your targeting accurate and relevant.

Examples of Custom Audiences in Action

Let’s take a look at a few examples of how businesses can use custom audiences:

• E-commerce Store: An online retailer might create a custom audience based on users who have visited product pages but haven’t made a purchase. They could then retarget those users with ads offering a discount to encourage them to complete their purchase.
• SaaS Company: A SaaS company could create a custom audience of users who have signed up for a free trial but haven’t yet upgraded to a paid plan. They could use this audience to deliver ads that highlight the benefits of upgrading.
• Event Organizer: An event organizer might create a custom audience of people who have attended past events and use it to promote upcoming events to this highly engaged group.
