How to Create Facebook Retargeting Campaigns That Recover Lost Sales

Retargeting is the closest thing to free money in digital advertising. People who've already visited your website are 70% more likely to convert than cold traffic. They know who you are. They've shown intent. They just need a nudge.

Yet most businesses run cold ads constantly and ignore retargeting entirely. That's leaving thousands of pounds on the table every month. Here's how to set up Facebook retargeting campaigns that recover the sales you're currently losing.

Why Retargeting Outperforms Everything Else

The numbers are stark. Retargeting campaigns typically achieve:

3-5x higher click-through rates than cold ads
5-10x higher conversion rates
30-60% lower cost per acquisition
Click costs of £0.20-£0.50 vs £1-£3 for cold traffic

The reason is obvious when you think about it. Cold traffic doesn't know you. Warm traffic does. Warm traffic has already considered buying. They just need the right reminder at the right moment.

Step 1: Install the Meta Pixel

You cannot run effective retargeting without the Meta Pixel. Full stop.

Go to Ads Manager → Events Manager → Data Sources → Add New Data Source → Web → Meta Pixel.

Follow the instructions to add the Pixel code to your website. If you're on WordPress, plugins like "PixelYourSite" handle this in 30 seconds. If you're on Shopify, the integration is built in. For custom sites, paste the code into the head of every page.

Verify the Pixel is firing using the Meta Pixel Helper Chrome extension. If it's green, you're good.

Step 2: Set Up Standard Events

The Pixel tracks pageviews by default. But for proper retargeting, you need to track specific events:

ViewContent — viewed a product page
AddToCart — added something to cart
InitiateCheckout — started checkout but didn't complete
Purchase — completed purchase
Lead — submitted a form

E-commerce platforms like Shopify and WooCommerce set these up automatically. For custom sites, you'll need to add event code to the relevant pages.

The more events you track, the more granular your retargeting can be.

Step 3: Create Custom Audiences

Go to Ads Manager → Audiences → Create Audience → Custom Audience → Website.

Here are the audiences I'd recommend creating for almost every business:

All website visitors (last 30 days) — Your broadest retargeting audience. Good baseline.

Product page viewers (last 30 days) — People who looked at specific products. Higher intent.

Cart abandoners (last 14 days) — People who added to cart but didn't buy. Highest intent of any audience.

Checkout abandoners (last 7 days) — People who started checkout but didn't complete. Premium retargeting audience.

Past purchasers (last 180 days) — Existing customers. Use for cross-sell and repeat purchase campaigns.

You can also create audiences based on Facebook engagement:

Page engagers (last 60 days) — People who liked, commented, or shared your posts.

Video viewers (last 90 days) — People who watched 75% of your video ads.

Instagram engagers (last 60 days) — Same idea on Instagram.

Step 4: Build Your Retargeting Funnel

Don't treat all warm traffic the same. Different audiences need different messages.

Tier 1: Highest intent (cart abandoners, checkout abandoners)

Strongest offer (free shipping, discount code, urgency)

Most aggressive frequency (daily ads)

Highest budget allocation

Tier 2: Medium intent (product viewers, multiple-page visitors)

Reinforce value, address objections

Show social proof and testimonials

Different products to broaden interest

Tier 3: Low intent (general site visitors, video viewers, page engagers)

Brand-building messages

Lifestyle content

Step 5: Cart Abandonment Campaign

This is the highest-ROI campaign almost any e-commerce business can run.

Go to Ads Manager → Campaigns → Create → Sales.

At the Ad Set level, choose your AddToCart audience and exclude your Purchase audience (so you don't advertise to people who already bought).

Settings:

Budget: £5-15/day

Optimisation: Conversions (Purchase)

Audience: Cart abandoners (last 14 days), excluding purchasers (last 14 days)

Creative:

Show the exact products they abandoned (use Dynamic Ads if you have a product catalogue)

Strong offer: "Free shipping just for you"

Urgency: "Your cart is waiting — 20% off if you complete checkout in the next 24 hours"

Cart abandonment campaigns commonly recover 10-15% of abandoned carts. If your average cart is £80 and you have 100 abandonments per week, you're recovering £800-£1,200 weekly from a £35-£100 ad budget.

Step 6: Dynamic Product Ads (For E-commerce)

If you sell products, Dynamic Ads are mandatory. They automatically show people the exact products they viewed on your site.

Go to Commerce Manager → Catalogues → Create Catalogue. Upload your product feed (Shopify and WooCommerce do this automatically).

Then create a Dynamic Ad campaign:
Ads Manager → Campaigns → Create → Sales → Catalogue Sales → Use Catalogue.

Facebook will automatically generate personalised ads showing each user the products they viewed. Setup takes 30 minutes. Performance is typically 2-3x better than manual product retargeting.

Step 7: Frequency Capping

The biggest mistake in retargeting is showing the same ad to the same person 50 times. People get annoyed, hide your ads, and develop negative brand associations.

In Ad Set settings, set frequency caps:

Cart abandoners: Up to 7 impressions per week

Product viewers: Up to 4 impressions per week

General visitors: Up to 2 impressions per week

This keeps your ads effective without becoming intrusive.

Step 8: Refresh Creative Often

Retargeting audiences are smaller than cold audiences, which means they see your ads more often. Ad fatigue sets in faster.

Rotate creative every 2 weeks. Keep 3-5 different ad variants running at all times. When one starts losing performance, swap it out.

Step 9: Test Different Offers

Different retargeting offers work for different audiences. Test:

Discount codes ("10% off — code WELCOME")
Free shipping (works particularly well for cart abandoners)
Bonus items ("Buy now and get a free gift")
Social proof ("Over 5,000 customers love this")
Urgency ("Sale ends Sunday")
Risk reversal ("30-day money-back guarantee")

Track which offers convert best for each audience.

Step 10: Exclude Recent Purchasers

This sounds obvious, but I see businesses fail at it constantly. Don't advertise to people who just bought from you.

In every retargeting Ad Set, exclude your Purchase audience for the relevant time period:

One-time products: exclude purchasers from last 30 days

Subscription products: exclude purchasers from last 90 days

B2B services: exclude purchasers indefinitely

Nothing kills brand goodwill faster than seeing ads for something you bought yesterday.

Performance Benchmarks for Retargeting

Good retargeting campaigns achieve:

CTR: 2-5% (much higher than cold)

CPC: £0.15-£0.50

Conversion rate: 8-20%

ROAS: 5x-15x (vs 2-4x for cold campaigns)

If your retargeting ROAS is under 5x, something is wrong. Either your audiences are too broad, your creative is stale, or you're not excluding existing customers.

Common Retargeting Mistakes

Showing the same generic ad to everyone. Cart abandoners and brand engagers need different messages.

Not excluding purchasers. Wasting budget and annoying customers.

No frequency caps. Showing ads 100 times per person creates ad fatigue and brand damage.

Letting creative go stale. Refresh every 2 weeks.

Forgetting about brand-engaged audiences. Page engagers and video viewers are valuable retargeting audiences too.

Setting it and forgetting it. Retargeting needs ongoing optimisation, not just initial setup.

A Realistic Retargeting Setup

For most small businesses, here's a simple retargeting setup that works:

Campaign 1: Cart/lead abandoners — £10/day, strong offer
Campaign 2: Product viewers — £5/day, social proof
Campaign 3: All website visitors — £5/day, brand awareness
Total: £20/day, ~£600/month

This setup typically generates 5-15x return on ad spend for established businesses with decent traffic.

Managing multiple retargeting audiences, refreshing creative, and monitoring performance is genuinely complex. If that sounds like more than you want to handle, Pix-Vu automates the whole retargeting setup and optimisation for £99/month — including dynamic creative, frequency optimisation, and ROAS tracking.

Retargeting is the highest-leverage thing most advertisers can do. If you're running cold ads but not retargeting, fix that this week.
