In the current e-commerce ecosystem, 73% of consumers consult customer reviews before finalizing a purchase. However, very few brands exploit this gold mine for their retargeting campaigns. What if your customer reviews became your secret weapon for creating highly qualified audiences and multiplying your conversions?
Traditional retargeting often simply targets visitors who have abandoned their shopping carts. But by integrating data from your customer reviews into your audience strategy, you unlock untapped potential: segment according to real satisfaction, anticipate objections, and personalize your messages with surgical precision.
In this comprehensive guide, learn how to turn your customer reviews into high-performing audiences that convert up to 3 times more than traditional retargeting campaigns.
Traditional retargeting is based on a simple premise: a visitor who has shown interest in your site is more likely to convert than a stranger. But this approach ignores a crucial dimension: The level of trust.
Your customer reviews are not just testimonials. They are powerful behavioral indicators that reveal:
By combining this data with your advertising audiences, you create hyper-qualified segments capable of responding to the specific objections of each visitor profile.
Brands that incorporate customer feedback into their retargeting strategies see spectacular results:
These performances are explained by a simple principle: you no longer retarget anonymous people, but qualified profiles whose motivations and obstacles you understand.
Who are they? Visitors who spent time on your product pages, viewed your 4-5 star reviews, but didn't buy.
Why target them? They are already convinced by the quality, but need a final push: a discount, free delivery, or reinsurance on after-sales service.
Message type: âDid you like what our customers are saying? Take advantage of 15% off to take action now.â
This audience typically converts 2.3 times better than generic retargeting, because you are capitalizing on an already established trust.
Who are they? Visitors who viewed negative or mixed reviews, or who gave up after reading reviews that mentioned specific points of friction (price, delivery, size).
Strategy: Create campaigns that respond directly to objections identified in the reviews consulted.
Concrete example: If your reviews often mention âdelivery too longâ, create an audience of visitors who have read these reviews and retargate them with: â24-hour express delivery now available + Free size guideâ.
This approach turns a barrier into an opportunity and can recover up to 40% of dropouts linked to specific objections.
Who are they? Visitors who simultaneously consult your reviews AND those of your competitors (detectable via their cross-site navigation or their searches).
Message type: Highlight your differentiators proven by reviews: âAverage score 4.9/5 vs 4.2 among competitorsâ, â847 verified reviewsâ, or "98% of customers satisfied with the after-sales serviceâ.
With a competitive intelligence strategy (like the one offered by Insight Radar), you can even create campaigns that capitalize on the weaknesses of your competitors identified in their own reviews.
Who are they? Your customers who have purchased but have not yet left a review.
Objective: Smart double retargeting:
These customers are 7 times more likely to buy back if they become active contributors. A retargeting campaign with a simple message like âYour opinion counts: share your experience and receive 10% on your next purchaseâ generates a double ROI: more reviews + more recurring sales.
Who are they? Customers who have left a 5-star review but have not bought in 3-6 months.
Strategy: Create VIP campaigns that capitalize on their past satisfaction: âAs a 5-star customer, you deserve special treatment: -20% + priority after sales serviceâ.
This audience has a 4 times higher reactivation rate to a classic reactivation campaign, because you recognize their status as a satisfied customer.
Who are they? Customers who have left a 2-3 star review with specific and constructive reviews.
Critical mission: Win them back before they become active detractors.
Approach: Highly personalized campaign recognizing their feedback: âWe took into account your feedback on [specific problem]. Discover what we have improved + exclusive commercial gesture.â
According to a recent study, 68% of dissatisfied customers who receive a personalized response and appropriate compensation change their opinion in a positive way and buy back within 6 months.
To create these powerful audiences, you need to orchestrate multiple data sources:
1. Behavioral browsing data
2. Structured review data
3. Transactional data
To capture this data and sync it with your advertising platforms (Meta Ads, Google Ads, TikTok Ads), you need to set up custom events :
//Example of an event when consulting reviews
fbq ('trackCustom', 'reviewViewed', {
product_id: 'SKU123',
review_rating: 5,
review_count_viewed: 8,
review_theme: 'quality',
time_spent: 45
});
These events make it possible to build custom audiences in your ad manager. For example:
Modern platforms like Shopify, PrestaShop, or WooCommerce offer native integrations that automate this segmentation. Review Collect, for example, offers direct connectors with:

What is the minimum audience size required to launch these campaigns?
For Meta Ads and Google Ads, aim for at least 1,000 users per audience to get actionable results. If your volumes are lower, start with a single consolidated audience (âall review consultantsâ) before segmenting further. You can also use lookalike audiences to broaden your reach while maintaining quality.
How long does it take to see results?
The first performance indicators generally appear under 7-14 days, the time for advertising algorithms to learn and optimize. For a complete assessment of ROAS and the impact on the entire buying cycle, wait 30-45 days. Plan a test budget of at least âŹ500-1000 per segment for this learning phase.
Do you have to explicitly mention reviews in ads to comply with regulations?
Yes, absolutely. When quoting a customer review in an ad, you should:
Transparency builds credibility and prevents legal risks.
How can I avoid cannibalization between my different retargeting audiences?
Three essential techniques:
What if I don't have enough customer reviews yet?
If you have fewer than 50 reviews, focus on Acquiring reviews via dedicated campaigns (post-purchase SMS, incentives, automatic reminders). Once you have crossed the threshold of 100-200 reviews with an average score of 4+/5, you can launch your first retargeting campaigns. In the meantime, use long written testimonials or customer videos in your classic retargeting.
Can negative reviews be used positively in retargeting?
Yes, in a strategic way! If you have previous negative reviews that mention a problem you've since resolved, create âbefore-and-afterâ campaigns that show improvement: âYou were right: we listened to your feedback and improved [X]. Discover the new version approved by 94% of our customers.â This shows your responsiveness and turns a weakness into a proof of customer commitment.
Customer reviews are no longer a simple reinsurance element to be displayed on your product sheets. They are strategic assets which, properly used in your retargeting campaigns, can multiply your return on advertising investment by 3 to 5.
By segmenting your audiences according to their interaction with your reviews â what they have read, how long, what feeling â you create surgically accurate campaigns that speak directly to the motivations and obstacles of each visitor profile.
The good news? You already have everything you need: your happy customers who share their experiences daily. All you need is the methodology to turn this gold mine into audiences that convert.
