Digital Marketing Retargeting and Remarketing Ads
Only about 2 to 3 percent of first-time website visitors buy or take action on their initial visit. The other 97 percent leave — often not because they are uninterested, but because they got distracted, were not ready, or needed more time to decide. Retargeting brings those people back.
Retargeting (also called remarketing) means showing ads specifically to people who have already visited a website, watched a video, interacted with a social media page, or engaged with a brand in some way. These are warm audiences — not strangers. They already know the brand exists and showed genuine interest. Reminding them at the right moment converts them at a far higher rate than cold audiences.
The Forgotten Shopping Cart Diagram
Imagine walking into a shop, picking up a jacket, carrying it to the counter, and then putting it back on the shelf and walking out without buying. The shop owner has your phone number and calls you the next day: "Hi, the jacket you liked is still here. We are also offering free alterations this week."
That call is retargeting. The person already showed clear purchase intent. A timely, relevant follow-up converts a "maybe" into a "yes."
In e-commerce, cart abandonment emails and retargeting ads serve exactly this function — and they are among the highest-converting tactics in all of digital marketing.
How Retargeting Works Technically
Retargeting uses tracking technology to identify people who have visited a website and then show them ads on other platforms they use.
The Tracking Pixel
A small piece of code installed on the website. When a visitor arrives, the pixel fires and drops a cookie in their browser. That cookie tags the visitor as someone who can be retargeted. The pixel reports this to the advertising platform (Facebook, Google, etc.), which then includes this person in a retargeting audience.
Facebook uses the Meta Pixel. Google uses the Google Ads tag or Google Analytics audience exports. LinkedIn has its own Insight Tag. Each platform requires its own tracking code.
Types of Retargeting Audiences
All Website Visitors
The broadest retargeting audience — everyone who visited any page on the website in the past 30, 60, or 90 days. Useful for brand awareness reminders but broad enough to include people who visited accidentally or were not genuinely interested.
Specific Page Visitors
People who visited a specific product page, service page, or pricing page. Someone who visited the pricing page is significantly more interested than someone who only saw the homepage. Targeting pricing page visitors with a special offer or a testimonial-focused ad moves them closer to a decision.
Cart Abandoners
People who added items to a shopping cart but did not complete the purchase. This is the hottest retargeting audience available — they selected a product and started the checkout process but stopped. A combination of retargeting ads and cart abandonment emails recovers 10 to 15 percent of these abandonments.
Past Purchasers
Customers who have already bought from the business. Retargeting existing customers with complementary products, subscription upgrades, or loyalty offers increases customer lifetime value. It is significantly cheaper to retain and upsell an existing customer than to acquire a new one.
Video Viewers
People who watched a certain percentage of a video ad (25%, 50%, 75%, or 95%). Someone who watched 75% of a product explainer video is clearly interested. Retargeting them with a direct purchase offer converts better than showing the same awareness video again.
Email List Retargeting
Upload the business's email subscriber list to Facebook, Google, or LinkedIn. The platforms match these emails to user accounts and show ads to those specific people. Email subscribers already trust the brand — seeing ads in addition to emails reinforces the relationship and drives higher conversion rates.
Retargeting Ad Strategy by Funnel Stage
Top of Funnel Retargeting
Target people who visited the website but spent very little time. They barely got introduced to the brand. Show them an educational video, a compelling brand story, or a strong introductory offer to re-engage their interest.
Middle of Funnel Retargeting
Target people who visited multiple pages, spent considerable time on the site, or watched a product video. These people are genuinely interested but not yet decided. Show them testimonials, case studies, comparison content, or free trial offers that address hesitation.
Bottom of Funnel Retargeting
Target cart abandoners, pricing page visitors, and checkout starters. These people were on the verge of buying. A time-limited discount, free shipping offer, or simple reminder ad often converts them. Keep these ads direct and focused on removing the final barrier to purchase.
Retargeting Best Practices
Frequency Management
Retargeting audiences are small compared to cold audiences. Without frequency caps, the same person sees the same ad constantly — which feels intrusive and damages brand perception. Cap retargeting ads at 3 to 5 impressions per week and refresh the creative regularly to avoid audience fatigue.
Exclusion Lists
Exclude people who have already converted from seeing conversion ads. Showing a "Buy Now — First Order Discount" ad to someone who already purchased is confusing and wasteful. Maintain an exclusion list of recent buyers and update it regularly.
Sequence Ads
Show different ads in sequence based on time elapsed since the last visit. Day 1 after visiting: product reminder. Day 3: customer testimonial. Day 7: limited-time offer. Day 14: final reminder. This narrative approach feels less like spam and more like a helpful follow-up conversation.
Remarketing vs. Retargeting
The two terms are often used interchangeably. In practice, retargeting usually refers to showing display or social ads to past website visitors using pixels. Remarketing more specifically refers to Google's term for the same concept, or to email-based follow-up campaigns to existing customers. Both achieve the same fundamental goal: re-engaging people who showed prior interest.
