How to Create Meta Custom Audiences in the Facebook/Meta Ads Manager
Step-by-Step Guide to Creating Custom Audiences
Now that you’ve got a handle on the basics, let’s dive into the process of building your first Custom Audience. Everything happens within Meta Ads Manager, so make sure you’re logged in and ready to go.
How to Access Meta Ads Manager
Start by logging into your Facebook account or your Meta for Business account. If you manage multiple ad accounts, double-check that you’re in the right one before moving forward.
Once logged in, open Meta Ads Manager and look for the 'Audiences' option in the left-hand menu. If it’s not visible, click the menu icon to expand 'All Tools', where you’ll find it listed. This is your go-to section for managing all types of audiences - whether it’s Custom Audiences, Lookalike Audiences, or saved audiences.
To get started, click on "Create Audience" or "Create New" (depending on whether you already have audiences set up). From the dropdown menu, select "Custom Audience". This opens the workflow where you’ll configure everything. The next step is choosing the data source for your audience.
Choosing Your Audience Sources
Meta provides several data sources for building Custom Audiences. Your choice here shapes how the rest of your setup will look, as each source has its own requirements and strengths.
Website Traffic: Use the Meta Pixel to create audiences based on page visits, specific actions, or time spent on your website.
Customer Lists: Upload a list of email addresses, phone numbers, or other customer details. Meta matches this data to user profiles, making it a great way to target existing customers, newsletter subscribers, or leads from other platforms. Keep in mind, the match rate depends on how recent and accurate your data is.
App Activity: If your app uses the Meta SDK, you can build audiences based on in-app behaviors like purchases, level completions, or content views. This is especially useful for apps with high user engagement.
Engagement Audiences: These are based on interactions with your Facebook or Instagram content. For example, you can target users who’ve watched your videos, liked your posts, or visited your profile. These audiences often consist of people who are already familiar with and interested in your brand.
Pick the source that aligns with your campaign goals, then move on to defining audience rules and retention periods.
Setting Up Audience Rules and Retention Periods
Once you’ve selected your data source, it’s time to set the rules for who gets included in your audience. These rules help you focus on users with specific behaviors.
You’ll also need to define a retention period, which determines how long someone stays in your audience after taking a specific action. Retention periods typically range from 7 to 180 days, depending on your goals. For example:
Shorter periods (7–14 days) work well for time-sensitive promotions.
Longer periods (30–90 days) are ideal for building larger audiences or campaigns aimed at users with longer decision-making processes.
Instead of targeting every website visitor, narrow your focus to users who show higher intent - like those who visit multiple pages, spend significant time on your site, or view key pages like pricing or product details.
For customer lists, consider segmenting based on factors like purchase history, lifetime value, or engagement level. You can even include extra details like purchase amounts or dates for advanced targeting.
To stay organized, use clear and descriptive audience names (e.g., 'PricingPage_30Days'). It’s also a good idea to create multiple versions of similar audiences with different retention periods or rules. Testing these variations can help you discover which configurations deliver the best results.
Lastly, keep an eye on the estimated audience size. If your audience is too small, Meta’s algorithms might struggle to optimize your campaign. On the other hand, an audience that’s too large can water down your targeting precision.
Advanced Custom Audience Targeting Methods
Taking your Custom Audience setup to the next level can help you zero in on the right people while cutting down on unnecessary ad spend. Here’s how you can refine your approach.
Combining and Excluding Audiences
Meta Ads Manager allows you to mix and match multiple Custom Audiences or exclude certain groups to sharpen your targeting. For instance, you could combine recent website visitors with your email subscriber list to engage users who are already familiar with your brand.
Exclusions can be just as important. Start with your main audience and exclude groups like recent buyers to avoid redundancy. Another powerful tactic is layering multiple audience segments. For example, you could target users who visited key pages and also engaged with your content, creating a pool of highly qualified prospects.
Once you've mastered combining and excluding, you can elevate your strategy with behavior-based segmentation.
Behavior-Based Audience Segmentation
This method dives deeper into user actions and engagement patterns, letting you craft audiences based on how they interact with your brand. Here are a few ways to segment by behavior:
Time-based segmentation: Focus on users who engage repeatedly within a short span or re-engage those who haven’t interacted recently.
Engagement depth: Separate casual browsers from users who explore multiple pages or spend significant time on your site.
Cross-platform behavior: Identify users active on one platform but not another, encouraging them to engage across all your channels.
Sequential behavior targeting: Pinpoint users who follow specific steps, like viewing product details and checking shipping info - this signals strong buying intent.
Frequency-based segmentation: Target users who interact often, as their consistent engagement suggests a higher likelihood of conversion.
Fine-tuning these segments is key, but keeping them effective requires ongoing maintenance.
Custom Audience Maintenance Best Practices
To keep your Custom Audiences performing at their best, regular updates and audits are essential. Without upkeep, segments can either become too narrow to be useful or too broad to drive meaningful results.
Start by refreshing your customer lists. Remove outdated or inactive contacts to ensure your data stays accurate, which translates to better ad performance. Also, review your data sources and retention policies to stay compliant with regulations like CCPA and GDPR. Be sure to remove users who’ve opted out of tracking.
Keep an eye on metrics like acquisition costs, conversion rates, and return on ad spend to identify which segments are delivering the best results. Meta’s Audience Overlap tool is also handy for spotting excessive overlap between segments, which can lead to internal competition.
Finally, use consistent naming conventions and document audience details - such as data sources, segmentation rules, and update schedules. This keeps everything organized, simplifies management, and makes collaboration with your team much easier. Regular maintenance ensures your targeting efforts remain sharp and effective.
Custom Audience Use Cases and Optimization Tips
Once you've set up your audiences, it's time to fine-tune your campaigns for maximum impact. Custom Audiences are a powerful tool to enhance ad performance and improve your return on investment (ROI). Here's how you can make the most of them.
Common Use Cases for Custom Audiences
Recover abandoned carts. Target users who added items to their cart but didn’t complete the purchase in the last 7 days. These individuals have already shown interest, making them ideal for ads featuring special discounts or reminders to finish their purchase.
Retain and upsell to existing customers. Create an audience of customers who bought something within the last 90 days, but exclude those who made recent purchases to avoid overloading them with ads. Focus on promoting complementary products, upgrades, or loyalty programs to strengthen their connection with your brand.
Re-engage dormant users. Build an audience of users who interacted with your site or content 30-90 days ago but haven’t returned since. These users are familiar with your brand but may need a little push. Offer them exclusive deals, fresh content, or updates on new products to reignite their interest.
Target high-value prospects using multiple signals. Combine data points like visits to your pricing page, resource downloads, and time spent on your site (e.g., over 3 minutes). This approach zeroes in on users who show strong purchase intent across various interactions.
Fine-tune seasonal campaigns with historical insights. If you’re in retail, create audiences based on customers who shopped with you during last year’s holiday season or other big promotions. Reach out to them early with sneak peeks of upcoming collections or early access to special discounts.
These examples illustrate how Custom Audiences can be tailored to specific goals, but ongoing optimization is critical to keeping your campaigns effective.
How to Optimize Custom Audiences
To get the best results from your Custom Audiences, use these proven tips to refine and improve your performance.
Aim for audiences between 1,000 and 50,000 users. If your audience is too narrow, try expanding the retention period or loosening your filters. If it’s too broad, tighten the criteria or reduce the timeframe to focus on more relevant users.
Test different retention periods. For example, a 30-day retention period might work well for fast-moving products, while businesses with longer sales cycles, like B2B services, may find a 180-day period more effective. Experiment to see what delivers the lowest cost per acquisition for your business.
Keep your data fresh. Stale data can hurt performance, so update your customer lists regularly. Automate data syncing wherever possible to save time and ensure accuracy.
Match audience type to your campaign goals. Use broader audiences for awareness campaigns and more targeted ones for conversions. Avoid running the same audience across multiple campaigns unless you’re testing different ad creatives.
Allocate more budget to top-performing audiences. Track your cost per result across different groups and shift more budget toward the ones delivering the best outcomes. At the same time, set aside some funds to test new audience segments and uncover untapped opportunities.
Rotate ad creatives every 2-3 weeks. Watch your frequency metrics and swap out creatives when performance starts to dip. This helps combat ad fatigue and keeps your messaging fresh.
Test platform-specific performance. Some audiences perform better on Facebook, while others might excel on Instagram. Run platform-specific campaigns to see where your audience engages most effectively.
The secret to success with Custom Audiences is constant experimentation and adjustment. What works today may not work tomorrow, so stay adaptable and rely on performance data to guide your strategy. By doing so, you’ll keep your campaigns sharp and your results strong.

Summary and Next Steps
Key Points to Remember
Custom Audiences in Meta Ads let you target people who are already familiar with your brand - whether they’ve visited your website, interacted with your content, or made a purchase. This familiarity often leads to better conversion rates and a stronger return on ad spend (ROAS).
To set up a Custom Audience in Meta Ads Manager, you’ll need to choose a data source, define a retention period, and set targeting rules. Audiences created from website traffic, customer lists, or engagement data can significantly improve your targeting, especially when they include at least 1,000 users.
You can take things further with advanced techniques like combining or excluding audiences. For example, you can create lookalike audiences based on your top customers, exclude recent buyers to avoid unnecessary spending, or segment users by their behavior. Keeping your audiences updated ensures they stay relevant and aligned with changing customer habits.
If managing Custom Audiences feels overwhelming - especially across multiple campaigns - tools like AdAmigo.ai can help. This platform uses AI to handle audience creation, updates, and optimization for you, freeing up your time to focus on strategy and results.
