How to Retarget with Facebook Ads and Boost Your Online Sales (Complete Guide)

Retargeting is one of the most powerful strategies to increase conversions and maximize your return on ad spend (ROAS). By targeting users who have already interacted with your brand, you can significantly improve sales.

✔ What is a Custom Audience?
✔ Why Retargeting Works Better Than Cold Audiences
✔ How to Set Up a Custom Audience in Facebook Ads
✔ Best Ad Strategies for Retargeting

1. What is a Custom Audience?

A Custom Audience is a group of people who have already engaged with your business, such as:

Past customers (from your eCommerce store or marketplace)
Website visitors (who viewed products but didn’t buy)
App users or engagement-based audiences (from Facebook/Instagram)

Since these users are already familiar with your brand, they are warmer leads and more likely to convert.

2. Why Retargeting Works Better

✅ Higher Trust: Customers who bought from you before trust your brand.
✅ Lower Ad Costs: Retargeting is cheaper than cold audience campaigns.
✅ Better Conversions: Warm audiences are closer to the bottom of the funnel (ready to buy).

3. How to Create a Custom Audience in Facebook Ads

Step 1: Go to Facebook Ads Manager

Navigate to Audiences under Business Tools.
Click Create Audience → Custom Audience.

Step 2: Choose Your Audience Source

You can create a Custom Audience from:

Customer List (upload a CSV of emails/phone numbers)
Website Traffic (track users who visited but didn’t buy)
App Activity (if you have a mobile app)
Engagement (video views, lead forms, etc.)

Step 3: Upload Your Customer List (For Past Buyers)

Download Facebook’s CSV template and format your customer data.
Upload the file and match columns (email, phone, etc.).
Facebook will verify and create your audience.

Step 4: Exclude Recent Buyers (Optional)

To avoid showing ads to people who just purchased, exclude them using:

Purchase window (last 30 days)
Lookalike Audiences (for scaling)

4. Best Ad Strategies for Retargeting

A. Use Carousel Ads (For Multiple Products)

Since past buyers already know your brand, showcase multiple products in a single ad.

Highlight bestsellers or new arrivals.
Include discounts for returning customers.

B. Offer Exclusive Discounts

“Welcome Back” coupon codes increase conversions.
Limited-time deals create urgency.

C. Dynamic Product Ads (For Abandoned Carts)

Automatically show products users viewed but didn’t buy.
Works best with Facebook Pixel tracking.

D. Video Ads (For Brand Storytelling)

Use testimonials or behind-the-scenes content.
Works well for engagement retargeting.

5. Budget & Optimization Tips

Start with $10-$20/day and scale based on performance.
Exclude buyers from the last 30 days to avoid wasted spend.
Test different creatives (carousel vs. video vs. single image).

Final Thoughts

Retargeting with Custom Audiences is a high-converting, low-cost strategy. By focusing on warm leads, you can boost sales, improve ROAS, and build customer loyalty.
