Retargeting Deep Links for E-Commerce

Retargeting ads remind users about products they viewed but did not purchase. Adding deep links to retargeting campaigns makes the ad click-to-purchase path as short as possible: the user taps the ad and lands directly on the product they were considering, with their cart or preferences intact.

For link retargeting strategies, see link retargeting: add pixels to every shared link. For re-engagement campaigns, see re-engagement campaigns: winning back lapsed users.

Why Retargeting Needs Deep Links

Standard retargeting flow without deep links:

1. User views a product in your app.
2. User leaves without purchasing.
3. Retargeting ad shows the product on Instagram/Facebook.
4. User taps the ad.
5. App opens to the home screen (user must find the product again).
6. User gives up.

Retargeting flow with deep links:

1. User views a product in your app.
2. User leaves without purchasing.
3. Retargeting ad shows the product on Instagram/Facebook.
4. User taps the ad.
5. App opens directly to the product page they were viewing.
6. User adds to cart and purchases.

Flow	Steps to Purchase	Conversion Rate
Without deep link	5-8 taps after ad click	Baseline
With deep link	1-2 taps after ad click	2-4x higher

Retargeting Deep Link Structure

Product-Level Retargeting

Link directly to the specific product the user viewed:

https://yourstore.com/product/SKU-12345?ref=retarget&campaign=abandoned-browse

Cart-Level Retargeting

For users who added items to cart but did not checkout:

https://yourstore.com/cart?restore=session-abc&ref=retarget-cart

The deep link restores the user's cart state, so they land on a populated cart ready for checkout.

Category-Level Retargeting

For users who browsed a category without viewing specific products:

https://yourstore.com/browse/mens-shoes?sort=popular&ref=retarget-browse

Dynamic Product Ads

Dynamic retargeting ads automatically show products from your catalog based on the user's browsing history. Each ad unit links to a specific product:

User Behavior	Ad Content	Deep Link
Viewed product X	Shows product X with price	/product/X?ref=dynamic-retarget
Viewed X, Y, Z	Carousel of X, Y, Z	Each links to /product/:id
Added X to cart	Shows X with "Complete your purchase"	/cart?restore=session&ref=cart-retarget
Purchased X	Shows complementary products	/collection/goes-with-X

Implementation

Setting Up Retargeting Audiences

To retarget users with product-specific deep links, you need to pass event data to your ad platforms:

1. Track in-app events: Product views, add-to-cart, purchase.
2. Send events to ad platforms: Via SDK integrations (Meta Pixel/SDK, Google Ads SDK).
3. Configure dynamic product catalog: Upload your product feed to the ad platform.
4. Set up dynamic ad templates: The ad platform automatically selects products based on user behavior.
5. Attach deep links: Each dynamically generated ad links to the specific product.

Platform-Specific Configuration

Meta (Facebook/Instagram):

• Use the Meta SDK for app event tracking.
• Configure deep link URLs in your product catalog feed.
• Each product in the feed includes a deep_link field pointing to the in-app destination.

Google Ads:

• Use Google App Campaigns with deep linking.
• Configure app links in your Merchant Center product feed.
• Dynamic remarketing ads automatically use the deep link from the feed.

Deferred Deep Linking for Reinstalls

Some retargeted users may have uninstalled your app. When they tap the retargeting ad:

1. The deep link detects the app is not installed.
2. Redirects to the app store.
3. After reinstallation, deferred deep linking opens the app to the product they were being retargeted on.

Without deferred deep linking, reinstalled users land on the home screen with no context, and the retargeting effort is wasted.

Retargeting Strategies

Timing Windows

Window	Strategy	Deep Link Destination
0-1 hours	Abandoned browse reminder	Product viewed
1-24 hours	Abandoned cart recovery	Cart restoration
1-7 days	Browse retargeting	Products viewed + similar items
7-30 days	Win-back with incentive	Product viewed + discount
30+ days	General re-engagement	Personalized recommendations

Frequency Capping

Retargeting without frequency caps annoys users:

Timeframe	Maximum Impressions	Purpose
Per day	2-3	Avoid ad fatigue
Per week	7-10	Maintain presence without annoyance
Per product	5-7 total	Move on if user is not interested

Measuring Retargeting Deep Link Performance

Metric	Formula	Benchmark
Click-through rate (CTR)	Ad clicks / Impressions	1-3% (retargeting typically higher than prospecting)
Deep link activation rate	App opens at target page / Ad clicks	70-85%
Cart recovery rate	Recovered carts / Abandoned carts retargeted	5-15%
ROAS	Revenue from retargeted users / Ad spend	5-15x (retargeting usually highest ROAS)
Incrementality	Retarget conversion rate – Organic recovery rate	Varies

Testing Incrementality

The key question with retargeting: would the user have purchased anyway? Run a holdout test:

1. Split your retargeting audience 90/10.
2. Show ads to 90% (test group).
3. Show no ads to 10% (holdout group).
4. Compare conversion rates.

The difference is the incremental value of retargeting. If both groups convert at similar rates, your retargeting may not be adding value.

Common Mistakes

Mistake	Impact	Fix
Retargeting ads link to home screen	Users cannot find the product, conversion drops	Deep link to the exact product or cart
No frequency cap	Users feel stalked, negative brand perception	Cap at 2-3 impressions per day
Retargeting purchasers with the product they bought	Annoying and wasteful	Exclude recent purchasers from product-specific retargeting
No cart restoration in deep links	Abandoned cart users must re-add items	Restore cart state via deep link parameters
No deferred deep linking	Reinstalled users land on home screen	Implement deferred deep linking for app reinstalls
Same retargeting for all time windows	Missing urgency signals	Adjust messaging and offers by recency

Tolinku for Retargeting

Tolinku provides deep link routes for retargeting campaigns. Set up routes like /product/:sku or /cart that your retargeting ads link to. The platform handles platform detection (iOS/Android) and deferred deep linking for users who need to reinstall. Analytics track click-through and conversion per campaign, so you can measure the impact of adding deep links to your retargeting flow.
