Retargeting

Retargeting is a digital advertising strategy that serves ads to people who have previously interacted with your content or website but did not complete a desired action, such as signing up or making a purchase. It works by placing a small [tracking pixel](/glossary/tracking-pixel) on your content that adds visitors to an audience list. Ad platforms then display your ads to those visitors as they browse other websites or social media, keeping your brand visible during the consideration phase. The goal is to re-engage warm prospects who already showed interest, rather than reaching completely cold audiences.

Most first-time visitors do not convert immediately — they browse, compare options, and leave. Retargeting gives publishers and marketers a second, third, and fourth chance to reach people who already showed interest by viewing a flipbook, catalog, or document. Because these audiences are pre-qualified (they actively engaged with your content), retargeting campaigns typically deliver higher click-through rates and lower cost per acquisition compared to cold advertising. For content-heavy businesses like publishers and catalog-based retailers, retargeting transforms one-time readers into repeat visitors and buyers.

FlipLink supports [Tracking Pixels](/features/tracking-pixels) that let you add Facebook Pixel, Google Ads, and other retargeting tags directly to your flipbooks and documents. When a reader opens your publication, the pixel fires and adds them to your retargeting audience on the corresponding ad platform. You configure pixel IDs in each publication's settings without writing any code. Combined with [Analytics & Insights](/features/analytics-and-insights), you can identify which publications drive the most engaged audiences and focus your retargeting budget on the right content. Since FlipLink tracks [scroll depth](/glossary/scroll-depth) and page views, you can build audience segments based on how much of your publication someone actually read — targeting deep readers differently from casual browsers.

These terms are often used interchangeably, but there is a practical distinction. **Retargeting** typically refers to serving paid ads (display, social, video) to previous visitors via pixel-based audience tracking. **Remarketing** traditionally refers to re-engaging previous customers through email — for instance, sending an abandoned cart email. Google blurs the line by calling its pixel-based ad feature "remarketing," but the underlying mechanism is the same as retargeting. In practice, the most effective approach combines both: use retargeting ads to stay visible on social feeds and websites, and use remarketing emails to deliver personalized messages directly. FlipLink supports the retargeting side through tracking pixels. For the remarketing side, you can use [lead capture](/features/lead-capture) forms to collect email addresses from flipbook readers and feed those into your email marketing platform.

- **Segment your audiences.** Do not show the same ad to everyone who viewed your flipbook. Separate deep readers (who viewed most pages) from quick bouncers. Tailor messaging to each group — deep readers may respond to product-specific offers, while bouncers may need a broader value proposition. - **Set frequency caps.** Showing the same ad too many times creates annoyance, not conversions. Most ad platforms let you limit how often each person sees your retargeting ad. A cap of 3 to 5 impressions per day per person is a reasonable starting point. - **Use burn pixels.** Once someone converts, stop showing them the acquisition ad. Place a "burn pixel" on your conversion page to exclude converters from retargeting audiences automatically. - **Refresh your creative.** Ad fatigue sets in quickly with retargeting because the same small audience sees your ads repeatedly. Rotate creative every two to three weeks. - **Respect privacy.** Include clear cookie consent mechanisms and honor opt-out requests. Retargeting without transparency damages trust.

A furniture showroom publishes its seasonal collection as a FlipLink flipbook with a Facebook Pixel and Google Ads tag installed. Over two weeks, 4,000 people view the flipbook. The marketing team creates three retargeting segments: readers who viewed the living room section, readers who spent time on the bedroom collection, and readers who reached the pricing page. Each segment receives tailored ads on Instagram and the Google Display Network featuring the specific category they browsed. The pricing-page segment also gets a limited-time discount offer. The result is a focused campaign where each viewer sees relevant products instead of generic brand ads.
