Want to recover sales from abandoned carts? Google Ads remarketing helps you reconnect with shoppers who leave without buying. By targeting users across platforms like Google Search, YouTube, and the Display Network, you can show personalized ads that bring them back to complete their purchase. Here's how:
Install a remarketing tag on your site to track cart activity.
Create remarketing lists based on cart behavior, like "added to cart but didn’t buy."
Use dynamic ads to show the exact products shoppers left behind.
Segment audiences by cart value or abandonment timing for precise targeting.
Optimize campaigns with metrics like ROAS, CTR, and cart recovery rates.
With 75% of cart abandoners planning to return later, retargeting is a cost-effective way to boost conversions. Let’s dive into the steps to set up and optimize these campaigns.
How to Setup Add To Cart Event on Google Ads Dynamic Remarketing to Target Shopify Cart Abandoners
Installing and Configuring the Google Ads Remarketing Tag
Adding the Google Ads remarketing tag to your site is essential for tracking visitor behavior and retargeting users who abandon their carts. This tag monitors actions like adding items to a cart, enabling you to later serve tailored ads. It consists of two components: the Google tag, which goes on every page, and an optional event snippet for specific actions, like cart or checkout pages.
Step 1: Install the Remarketing Tag
To begin, log in to your Google Ads account and navigate to Tools > Shared Library > Audience Manager > Your Data Sources. From there, click "Set up tag" on the Google Ads tag card. You'll receive a code snippet that needs to be placed between the and tags on every page of your website.
If you're setting up dynamic remarketing, choose the option labeled "Collect specific attributes or parameters to personalize ads". Then, add the event snippet with the parameter to your cart pages.
For Shopify users, insert the tag code into the section of the file. If you're using Google Tag Manager, you’ll need the Conversion ID and Conversion Label from the Audience Manager to create a "Google Ads Remarketing" tag.
Step 2: Verify Tag Installation
Once the tag is installed, use the Google Tag Assistant Chrome extension to confirm it's working correctly. When the tag functions as expected, the extension will show a green or blue icon. A yellow or red icon signals an issue that needs attention.
You can also check the tag status in Google Ads under Audience Manager > Audience Sources. The status may appear as "unverified", "inactive", or indicate successful data collection. Additionally, the Google Ads tag card displays a graph to track hits over time. Keep in mind that you need at least 100 active users for Display Network campaigns or 1,000 active users for Search Network campaigns before your ads can run effectively.
Step 3: Link Google Analytics 4 to Google Ads
Integrating Google Analytics 4 (GA4) with Google Ads helps you create more refined remarketing audiences. For example, you can target users who added items to their cart but didn’t complete the purchase.
To enable this, activate Google Signals in GA4 by going to Admin > Property Settings > Data Collection. Then, in Google Ads, head to Tools and Settings > Linked Accounts to connect your GA4 property. Once linked, check the Audience Manager in Google Ads to ensure your GA4 segments are syncing and populating correctly.
With the remarketing tag installed and verified, you’re all set to create targeted audience segments and retarget cart abandoners effectively.
Building Remarketing Lists for Cart Abandoners
Once your remarketing tag is installed and verified, it’s time to create audiences to retarget users who abandoned their shopping carts. These lists determine who will see your retargeting ads.
Creating Targeted Remarketing Lists
There are two main ways to set up cart abandonment audiences: using Google Analytics 4 (GA4) templates or creating them manually in Google Ads.
Using GA4 Templates: Head to Admin > Audiences > New audience in GA4. Under "Use a reference", choose "Shopping" and then "Cart abandoners". This template automatically identifies users who triggered the event but excludes those who completed the event. Note that this template is only available if your GA4 property’s industry category is set to Shopping, Jobs & Education, Real Estate, or Travel.
Manual Setup in Google Ads: Navigate to Audience Manager in Google Ads and create a "Website visitors" list. Use URL-based rules to define your audience: include users who visited pages with URLs containing , and exclude those who landed on pages with or in the URL.
Audience Logic | Inclusion Criteria | Exclusion Criteria |
URL-Based | URL contains /cart | URL contains /thank-you or /order-confirmation |
Event-Based | add_to_cart event triggered | purchase event triggered |
Funnel-Based | Use the begin_checkout event to capture higher-intent users | Exclude those who triggered the purchase event |
For a more refined approach, you might want to separate audiences into two groups: those who "added to cart" and those who "began checkout" but didn’t complete the process. Users in the checkout group usually show stronger purchase intent and may respond better to offers like free shipping or discounts.
Once your lists are set up, the next step is to decide how long users should remain on these lists.
Setting Membership Duration
Membership duration determines how long a user stays on your remarketing list after abandoning their cart. While the default is 30 days, you can extend this period up to 540 days, depending on your sales cycle.
For low-cost, impulse purchases, a shorter duration (e.g., 30 days) is often sufficient since buying decisions are made quickly.
For higher-priced items with longer decision-making processes, consider extending the duration to 60, 90, or even 180 days to keep users on your list until they’re ready to buy.
You can also create multiple lists with varying durations - such as 1-day, 7-day, and 30-day lists - to identify the most effective timing for your retargeting efforts and fine-tune your messaging.
After setting the duration, make sure your lists stay accurate by enabling automatic updates.
Enabling Automatic Audience Sync
To keep your audiences up-to-date in real time, enable automatic syncing between GA4 and Google Ads. Link your accounts (as outlined in Step 3), toggle on "Enable Personalized Advertising" in the integration settings, and activate Google Signals in GA4 under Admin > Property Settings > Data Collection.
Once this is set up, any audience you create in GA4 will automatically sync to the Google Ads Audience Manager within 24 to 48 hours. Keep in mind that GA4 audiences start collecting users only from the moment they’re created - they won’t include visitors from before the list was set up.
Lastly, ensure your lists meet the minimum audience size requirements before using them in campaigns: 100 active users for Display Network campaigns and 1,000 active users for Search Network campaigns. With automatic syncing, your audience will naturally grow as more users abandon their carts.
Segmenting Audiences for Personalized Campaigns
Once you've identified your cart abandonment audiences, the next step is to refine them with segmentation. This allows you to craft messages that resonate more effectively. For example, the way you approach someone with a $20 cart will differ from someone whose cart totals $500. By segmenting based on factors like timing and behavior, you can align your ads with each buyer's unique stage in the purchasing journey.
Segmentation by Abandonment Duration
Timing is a key factor in understanding cart abandonment. Shoppers who recently left their cart are often still considering a purchase, while those who abandoned weeks ago might need a stronger push. Break down your audience by how long it’s been since they abandoned their cart:
1–3 days (high intent): These shoppers are still in "buying mode." A simple message like "Forget something?" or "Your cart is waiting!" can be enough to bring them back.
4–10 days (moderate intent): These users may need a bit more encouragement, such as offering free shipping or a 10% discount.
11–30 days (low intent): For this group, rebuilding trust might be key. Use social proof like customer reviews or testimonials to reignite interest.
This segmentation strategy helps you tailor your approach to match the shopper's mindset at each stage.
Segmentation by Cart Value and Behavior
Not all carts are created equal, and understanding their value can help you allocate your resources wisely. Start by creating segments based on cart totals. For example:
High-Value Carts (over $200): These shoppers may respond well to premium offers like free shipping, discounts, or even personalized support.
Lower-Value Carts: A simple reminder or a free shipping offer might suffice for these audiences.
Behavior is another useful way to segment. Distinguish between users who merely added items to their cart and those who went as far as initiating checkout but didn’t finish. Checkout abandoners, having already entered their shipping details, often show stronger intent. Messages that include trust signals - like security badges, customer reviews, or "limited stock" alerts - can be particularly effective here.
Segment Type | Audience Criteria | Recommended Ad Creative |
Cart Abandoners | Added items to cart, didn’t checkout | "Forget something?" reminders with dynamic product images |
High-Value Abandoners | Cart total > $200 | Free shipping, a 10% discount, or VIP support |
Checkout Abandoners | Reached payment page, no purchase | Trust signals, customer reviews, or "Limited stock" messages |
Excluding Recent Purchasers
To avoid wasting your ad spend, make sure to exclude recent buyers from your retargeting campaigns. Use an exclusion list for "Recent Purchasers" to prevent redundant targeting. A 30-day exclusion period is common, but this can vary based on your product type. For consumables or items bought frequently, a shorter window (30–60 days) might work best. On the other hand, for one-time or infrequent purchases, you may want to extend this period.
Setting Up Remarketing Campaigns
Once you've defined your audience segments, it's time to create campaigns that bring cart abandoners back to complete their purchases. Google Ads provides two main options: dynamic remarketing, which shows users the exact products they left behind, and standard remarketing, which uses broader messaging across various platforms. Choose the approach - dynamic or standard - that aligns with your campaign objectives.
Dynamic Remarketing Campaigns
Dynamic remarketing takes product data from your Google Merchant Center feed to craft personalized ads that remind users of specific items they viewed. This strategy often yields impressive results, with businesses reporting noticeable boosts in click-through rates and revenue.
To get started, link your Google Merchant Center to your Google Ads account and ensure your product feed is verified. Dynamic remarketing is compatible with Display, Performance Max, and App campaigns. During setup, expand the "Additional settings", select "Dynamic ads", and check the option to "Use dynamic ads feed for personalized ads." Then, manually target the audience segment you created for shopping cart abandoners.
Using Responsive Display Ads allows Google to automatically pull product details and test different creative combinations for optimal performance. On average, the cost per click for dynamic remarketing campaigns ranges between $0.66 and $1.23.
Standard Remarketing Campaigns
If creating personalized product ads isn't an option, standard remarketing is a great alternative. This approach focuses on broader messaging and works across Display, Search, and YouTube networks. It’s particularly effective for promoting general offers like site-wide discounts or free shipping, as well as for building brand awareness.
To set up a standard campaign, start by creating a new campaign in Google Ads and selecting "Sales" as your objective. Then, choose the campaign type that fits your goals - Display for visual ads or Search for Remarketing Lists for Search Ads (RLSA). In the Audience Segments section, select your cart abandoner list. Keep in mind that Display campaigns require at least 100 active users over the past 30 days, while Search and YouTube campaigns typically need around 1,000 active users.
Campaign Type | Minimum Audience Size (30 Days) | Primary Use Case |
Display | 100 active users | Visual reminders across websites and apps |
Search (RLSA) | 1,000 active users | Ads tailored to users' search behavior |
YouTube | 1,000 active users | Video-based retargeting for engaged viewers |
Standard remarketing on the Display Network averages about $0.66 per click, while Search retargeting costs around $1.23 per click - much lower than the average $2.69 per click for standard search ads. For Display campaigns, use Responsive Display Ads by uploading multiple headlines, descriptions, and images, allowing Google to test combinations for the best performance.
Setting Bid Strategies and Frequency Caps
To maximize the effectiveness of your campaigns, pair your segmented audiences with smart bid strategies and frequency caps. Start with the Maximize Conversion Value bidding strategy to gather conversion data. Once you have enough data, switch to Target ROAS to optimize bids for a higher return. As Google explains:
Target ROAS lets you bid based on a target return on ad spend (ROAS). This Google Ads Smart Bidding strategy helps you get more conversion value or revenue at the target return-on-ad-spend (ROAS) you set.
For Search remarketing (RLSA), consider increasing bids for high-intent search terms like "Buy [Product Name]." Since these users already know your brand, more aggressive bidding can lead to better results. To keep your budget focused, disable optimized targeting in your campaign settings.
Frequency caps are another critical tool. Limit impressions to 3–5 per day or 10–15 per week to avoid overwhelming your audience. This balance ensures your brand stays top-of-mind without causing ad fatigue. Considering nearly 70% of online shopping carts are abandoned - and 75% of those customers still plan to purchase later - a well-timed reminder can make all the difference.

Designing High-Converting Ad Creatives
With your retargeting campaign set up, the next step is crafting ad creatives that drive conversions. These ads - whether dynamic product showcases or standard display formats - should address common barriers like shipping costs, trust concerns, or user distractions to bring back abandoned shoppers.
Dynamic vs. Standard Ad Formats
The choice between dynamic and standard ad formats depends on your business model and product catalog. Dynamic remarketing pulls product images, prices, and details directly from your Google Merchant Center feed, creating personalized ads that remind users of specific items they left behind. This tailored approach often leads to a 20% boost in click-through rates compared to static ads.
On the other hand, standard remarketing involves manually created visuals and messaging, making it a better fit for promoting site-wide sales, building brand awareness, or targeting service-based businesses without a product feed.
Format Type | Key Features | Best Use Case | Expected CTR Impact |
Dynamic Remarketing | Pulls product data from Merchant Center; personalized | E-commerce with large inventories; abandoned cart recovery | High (~20% lift) |
Standard Remarketing | Static visuals and messaging; manual setup | Brand awareness; service-based businesses; small catalogs | Moderate engagement |
Dynamic ads are ideal for businesses with extensive product inventories, while standard ads work well for promoting a single service or building general brand recognition. Once you've chosen the format, the next step is to refine your messaging to turn these visuals into actionable results.
Writing Persuasive Ad Copy
Your ad copy needs to inspire action. Start with headlines that emphasize benefits over features. For example, instead of "Stylish Office Chair", opt for something like "Upgrade Your Home Office with Comfort". Focus on the outcome your audience craves.
Incorporate elements of urgency and social proof to drive engagement. Highlight time-sensitive deals or customer reviews - ads featuring social proof can increase conversions by 10%, and combining multiple elements may boost conversions by up to 44%.
Address objections head-on. If shipping costs are a concern, lead with "Free Shipping." If trust is an issue, emphasize "Easy Returns" or "Money-Back Guarantee." Your call-to-action (CTA) should follow the MIC framework: it must Motivate the user, Inform them of the next step, and stay Concise. Use action-oriented phrases like "Complete Your Purchase Now" or "Return to Your Cart." Once your copy is ready, testing will help you identify what resonates most with your audience.
A/B Testing Ad Variations
Testing is the only way to pinpoint what works. Begin by setting up a control group with brand-focused ads that align with your website's design to build trust and engagement. Test individual variables - such as headlines, visuals, urgency, or incentives - and use Responsive Display Ads to let Google's AI identify winning combinations.
For example, compare benefit-driven headlines with feature-focused ones. Test urgency-driven phrases like "24 Hours Left to Save 20%" against social proof elements such as "Join 10,000+ Happy Customers". Experiment with visuals by contrasting static images with GIFs or short videos.
Track performance metrics closely - not just click-through rates but also conversion rates and return on ad spend (ROAS). Segment your tests by audience, such as targeting "Cart Abandoners" separately from "All Visitors", to ensure the data is accurate and actionable. Keep testing continuously, as today's winning strategy may need adjustments tomorrow.
Tracking and Optimizing Campaign Performance
Once your remarketing ads are live, the key to success lies in tracking the right metrics. These numbers will help you distinguish between campaigns that barely break even and those that generate strong returns. Start with Return on Ad Spend (ROAS), which shows how much revenue each dollar spent brings in. Keep an eye on Click-Through Rate (CTR) and Cart Recovery Rate, which measures the percentage of retargeted users who complete their purchase.
Another important metric is Impression Share (IS), which tells you how often your ads reach your target audience. Be cautious - hitting 100% impression share can lead to ad fatigue. If your list has 10,000 users but only 2,000 are being reached, your frequency caps might be too tight. Use GA4 event snippets (like "add_to_cart") to accurately track how well your ads are converting.
Key Metrics to Track
Your daily dashboard should focus on these essential metrics:
ROAS: Tracks how profitable your campaigns are overall.
CTR: Measures how effective your ad creative is. A CTR below 1% suggests your messaging could use some work.
Cart Recovery Rate: Indicates how many users who abandoned their carts eventually complete their purchase.
Cost Per Click (CPC): Helps gauge cost efficiency, especially compared to cold traffic campaigns.
Here’s a quick comparison: retargeting search ads average $1.23 per click, while standard search ads cost around $2.69. Display retargeting is even more cost-effective, averaging about $0.66 per click.
Metric | What It Measures |
ROAS | Revenue generated per dollar spent |
CTR | How often users click on your ads |
Cart Recovery Rate | Percentage of cart abandoners who complete their purchase |
Impression Share | Frequency of ad appearances to your audience |
To dive deeper, add UTM parameters to your landing page URLs for granular campaign analysis. Choose an attribution model that reflects the full impact of remarketing, since many conversions happen after multiple ad exposures. By tracking these metrics, you can fine-tune your campaigns and scale the ones that perform best.
Scaling High-Performing Campaigns
When scaling successful campaigns, don’t just throw more money at them. Instead, refine your approach. Segment your audiences by intent and bid higher for users who reached checkout pages compared to those who only browsed the homepage. Automated bidding strategies like "Maximize Conversion Value" or "Target ROAS" can help you focus on high-value conversions.
For products with longer decision-making cycles, consider extending your membership durations. Instead of the standard 30 days, expand to 60, 90, or even up to 540 days for high-ticket items. Check your placement reports regularly and exclude underperforming sites, such as parked domains or error pages. Shift your budget from ad groups with low engagement to those delivering better results.
Keep exclusion lists updated to avoid showing ads to recent purchasers - typically those who’ve bought within the last 30 to 90 days. Experiment with different membership windows, like a 7-day list for urgent promotions or a 30-day list for general reminders, to find the sweet spot for conversions. After fine-tuning your campaigns, you’ll be ready to take things to the next level.

FAQs
How can I check if my Google Ads remarketing tag is working properly?
To confirm that your Google Ads remarketing tag is functioning as it should, follow these steps:
Use Google Tag Manager's preview mode or Tag Assistant: These tools help you verify if the tag fires correctly when the page loads. Check that the tag is listed as "fired" during your test.
Inspect network requests in developer tools: Open your browser's developer tools and look for a network request to or a similar endpoint. This request should include your Google Ads conversion ID.
Check status in your Google Ads account: Go to Tools & Settings → Audience Manager in your account. If the remarketing tag shows "Tag is working" and your audience list begins to populate, it's a good sign everything is set up correctly.
If something seems off, revisit the tag setup in Google Tag Manager. Double-check the conversion ID and ensure the trigger conditions are configured properly. For a more thorough review, you can reach out to experts like Senwired to fine-tune your remarketing tag setup and make sure no leads are missed.
Why should you segment audiences by cart value and abandonment timing for retargeting?
Segmenting your abandoned-cart audience based on cart value lets you zero in on shoppers with higher purchase potential. By prioritizing these users with tailored offers and increased bids, you can make the most of your ad spend. Typically, these shoppers show a stronger intent to buy, meaning a well-timed nudge could easily lead to a conversion.
Another smart approach is grouping users by when they abandoned their carts. Timing is everything here. For instance, targeting those who left their carts within the past 24 to 48 hours can dramatically boost your chances of turning interest into action. This way, you’re reaching them while your products are still fresh in their minds, cutting down on wasted ad dollars and increasing recovered sales.
How can I improve my Google Ads to recover more abandoned carts?
To bring back more abandoned carts with Google Ads, focus on creating ad content that aligns with your audience’s intent. Start by building specific retargeting groups, like shoppers who left items in their carts, and craft ads that speak directly to their situation.
Leverage dynamic product ads to showcase the exact items left behind. This makes the ad feel personalized and relevant. Add a strong call-to-action like “Finish Your Purchase Now,” and consider including a limited-time offer, such as a discount or free shipping, to encourage quick action.
Don’t forget to use high-quality product images to catch the eye. Keep experimenting with different headlines, visuals, and promotions to find out what resonates most. These tactics can help you re-engage cart abandoners and turn them into paying customers.
