Retargeting Ads Explained: How to Bring Back Visitors Who Left Your Site

Published in Pay Per Click Advertising | Last updated: 2024

What is Retargeting and Why It Matters

Retargeting, also known as remarketing, is a digital advertising strategy that targets users who have previously visited your website but didn’t complete a desired action, such as making a purchase or signing up for a newsletter.

Consider this reality: according to industry research, approximately 98% of website visitors leave without converting. These aren’t necessarily lost causes—many are simply still in the decision-making process. Retargeting gives you the opportunity to re-engage these potential customers with relevant ads as they browse other websites, social media platforms, or search results.

The Business Case for Retargeting

The numbers speak for themselves. Research shows that:

• 70% higher conversion rates: Retargeted users convert at rates significantly higher than cold traffic audiences
• Lower cost per acquisition: CPAs for retargeted campaigns are often 50-60% lower than new customer acquisition
• Increased brand recall: Repeated exposure improves brand recognition and trust by 70-80%
• Extended customer lifecycle: Retargeting customers spend 20-40% more on average than first-time buyers

For example, if an e-commerce store has 10,000 monthly visitors with a baseline conversion rate of 2% (200 conversions), implementing retargeting could potentially increase conversions from abandoning visitors by 0.5-1%, effectively adding 50-100 additional conversions monthly without increasing traffic.

How Retargeting Works: The Technical Side

The Pixel-Based Tracking Method

The most common retargeting approach uses tracking pixels—small snippets of JavaScript code placed on your website. Here’s how it works:

1. A visitor lands on your website and the pixel is loaded in their browser
2. The pixel drops a cookie on their device (with proper consent)
3. When they leave your site and visit other websites, the pixel recognizes their cookie
4. The ad network displays your ads to this identified user across its network
5. You pay only when they see your ad (CPM model) or click it (CPC model)

List-Based Retargeting

List-based retargeting involves uploading customer data directly to ad platforms. You provide:

• Email addresses of past visitors
• Phone numbers of prospects
• Customer IDs from your CRM
• First-party data you’ve collected

The platform then matches these users in their network and serves your ads to them. This method is particularly valuable for B2B companies and high-value customer segments.

Types of Retargeting Strategies

Standard Retargeting

Standard retargeting targets all visitors who didn’t convert. It’s the broadest approach and works well for:

• Building brand awareness among interested audiences
• Products with lower price points
• Growing awareness of new offerings

Dynamic Retargeting

Dynamic retargeting shows users ads for the specific products they viewed on your site. A user who looked at blue sneakers sees ads for those exact blue sneakers, not random products. This approach:

• Increases relevance and conversion rates by 150-300%
• Requires a product feed integration with ad platforms
• Works best for e-commerce businesses with multiple SKUs

Sequential Retargeting

Sequential retargeting shows different ads based on user behavior. For example:

• First ad: Product benefits and features
• Second ad: Social proof and customer reviews
• Third ad: Limited-time offer or discount

Site Retargeting

This targets users based on specific pages visited. For instance:

• People who viewed pricing pages get discount offers
• Blog readers see related webinar invitations
• Cart abandoners get recovery ads with incentives

Popular Retargeting Platforms and Tools

Emerging Tools and Platforms

Programmatic advertising platforms like The Trade Desk and Rocket Fuel allow sophisticated retargeting across thousands of websites and apps with advanced audience segmentation and real-time bidding optimization.

Best Practices for Retargeting Success

Implement Proper Audience Segmentation

Don’t treat all visitors the same. Segment your retargeting audiences by:

• Pages visited: Product pages, pricing, blog content
• Time spent on site: Highly engaged vs. quick visitors
• Actions taken: Form submissions, video views, cart additions
• Device type: Mobile users often need different messaging

Implement Frequency Capping

Frequency capping limits how many times a user sees your ad. Best practices suggest:

• Display ads: 3-5 impressions per user per day
• Social ads: 2-3 impressions per user per day
• Search ads: No frequency cap needed (users are searching)

Ad fatigue is real—users who see your ad too many times often develop negative sentiment toward your brand. Google Ads data shows that impression frequency beyond 5-7 times per day actually decreases click-through rates.

Create Compelling Ad Creatives

Your retargeting ads should:

• Address the reason they left (price objection, shipping concerns, etc.)
• Include social proof and customer testimonials
• Feature limited-time offers or exclusive deals
• Use high-quality, product-focused imagery
• Include clear, compelling CTAs (“Complete Your Purchase,” “Learn More”)

Respect User Privacy and Consent

With regulations like GDPR, CCPA, and others:

• Obtain explicit consent before tracking visitors
• Provide easy opt-out mechanisms
• Use first-party data whenever possible
• Stay updated on privacy regulation changes
