A **Product Viewer Audience** is a defined group of people who viewed a specific product (or product category) on your website or app but didn’t complete a desired action—most commonly a purchase. In **Paid Marketing**, this audience is one of the highest-intent segments you can use for **Retargeting / Remarketing**, because it is based on observed behavior rather than assumptions.

Product Set Retargeting is a Paid Marketing approach that shows ads featuring *a curated set of products* to people who have already signaled intent—by viewing items, browsing categories, adding to cart, or purchasing in the past. It sits inside Retargeting / Remarketing, but instead of pushing one generic message to every past visitor, it uses product-level signals to make ads feel more relevant and timely.

Post-view Retargeting is a **Paid Marketing** technique within **Retargeting / Remarketing** that targets people **after they’ve been served an ad impression**, even if they **didn’t click**. Instead of relying on a website visit as the trigger, it uses “ad exposure” as the signal that someone may have interest and can be nurtured with a follow-up message.

Personalized Recommendations are product, content, or offer suggestions tailored to an individual’s predicted interests—delivered at the moment they are most likely to influence action. In **Paid Marketing**, they show up as dynamic ads, tailored landing pages, and customized creative that reflect what someone viewed, considered, or is most likely to buy next.

A **Past Purchaser Audience** is a group of people who have already completed a purchase with your business and can be targeted again through **Paid Marketing**. In **Retargeting / Remarketing**, this audience is uniquely valuable because you’re not trying to create trust from scratch—you’re building on an existing customer relationship to drive repeat purchases, upgrades, renewals, referrals, and higher lifetime value.

Modern buying journeys rarely move in a straight line from “first click” to “purchase.” People compare options, revisit pages, ask stakeholders, read reviews, and return later—often multiple times. In **Paid Marketing**, this messy middle is where a **Mid-funnel Audience** becomes most valuable.

Message Sequencing is the practice of planning and delivering ads in a deliberate order so prospects and customers see the “next best message” instead of the same creative repeatedly. In Paid Marketing, it turns disconnected impressions into a coherent progression—education, proof, offer, and reinforcement—based on what someone has already seen or done.

Membership Duration is one of the most underappreciated levers in Paid Marketing because it quietly controls *who* stays eligible to see your ads—and *for how long*. In Retargeting / Remarketing, it defines the time window that a user remains in a specific audience after they trigger a qualifying action, such as visiting a product page, adding to cart, or starting a trial.

A **Lapsed Customer Audience** is a defined group of past buyers who have stopped purchasing, renewing, or engaging for a meaningful period. In **Paid Marketing**, this audience is valuable because they already know your brand, have previously converted, and often require less education than new prospects. When used correctly, a Lapsed Customer Audience becomes one of the highest-leverage segments for **Retargeting / Remarketing**—helping you win back revenue that would otherwise drift to competitors.

Incremental Retargeting is a measurement-first approach to **Paid Marketing** that asks a simple but critical question: *Did this retargeting ad create additional conversions, or did it just claim credit for conversions that would have happened anyway?* In the world of **Retargeting / Remarketing**, that distinction determines whether you’re investing in real growth or paying for attribution illusions.

A **Holdout Audience** is a deliberately excluded group of people who *do not* receive a specific ad, campaign, or treatment—so you can measure what would have happened without it. In **Paid Marketing**, this is one of the most practical ways to answer a hard question: “Did our ads truly cause incremental conversions, or would many of these customers have converted anyway?”

A **High-intent Audience** is the set of people most likely to take a near-term action—buy, request a demo, book a call, or submit a lead form—because their behavior strongly signals they’re close to a decision. In **Paid Marketing**, identifying this audience is one of the fastest ways to improve efficiency because you’re prioritizing budget on users who have already shown meaningful interest rather than cold prospects.

Ghost Ads Methodology is a measurement approach in **Paid Marketing** that helps teams estimate the *incremental* impact of ads—especially in **Retargeting / Remarketing**, where conversions often would have happened anyway. Instead of relying only on click-based attribution or platform-reported conversions, Ghost Ads Methodology uses a controlled design that approximates a holdout group without fully removing people from targeting.

An **Exclusion Window** is a time-based rule that prevents ads from being shown to a person after a specific event—most commonly after they convert, purchase, or recently engaged. In **Paid Marketing**, this concept is essential because audiences are constantly changing, and the “right” message before conversion is often the “wrong” message after conversion.

Engagement Retargeting is a strategy in **Paid Marketing** where you show ads specifically to people who have *already interacted* with your brand—such as watching a video, reading key pages, interacting with a social post, starting a form, or using parts of your product experience. Within **Retargeting / Remarketing**, it shifts the focus from “visited the site” to “showed meaningful intent signals.”

Email is still one of the strongest intent signals in digital marketing: when someone clicks from a message you sent, they’ve raised their hand. **Email Clickers Retargeting** turns that signal into a focused **Paid Marketing** strategy by using those click actions to build audiences for **Retargeting / Remarketing** campaigns across ads and channels.

Dynamic Retargeting is a Paid Marketing tactic that automatically shows highly relevant ads—often featuring specific products, services, or content—to people who have already interacted with your website, app, or customer journey. It sits inside Retargeting / Remarketing, but adds a critical upgrade: instead of serving a single generic “come back” ad, Dynamic Retargeting personalizes the creative, offer, and product selection based on what the user actually viewed or did.

Modern audiences don’t experience channels in isolation. The same person might see your display ad on a news site, your paid social ad in a feed, and then a retargeting ad while browsing later. **Deduplicated Reach** is the way marketers estimate how many *unique people* were reached across those touchpoints—without double-counting the same individual multiple times.

Customer Match Retargeting is a **Paid Marketing** approach that uses your own first-party customer data (like email addresses, phone numbers, or other identifiers) to re-engage known people with tailored ads across ad networks. It sits at the intersection of audience strategy, lifecycle marketing, and **Retargeting / Remarketing**—but instead of relying only on website cookies or pixels, it focuses on matching existing customer records to advertising platform users.

A **Cross-sell Audience** is a purposely defined group of existing customers (or high-intent users) who are likely to buy an additional, complementary product or service. In **Paid Marketing**, this audience is most often activated through **Retargeting / Remarketing** because you already have signals—purchases, subscriptions, feature usage, content consumption, or customer status—that indicate what “next best offer” makes sense.

CRM Retargeting is a Paid Marketing approach that uses customer relationship management (CRM) data—such as leads, customers, and lifecycle status—to re-engage known audiences with tailored ads. Unlike tactics that rely primarily on anonymous browsing behavior, CRM Retargeting typically activates first-party identifiers (for example, email addresses or phone numbers) and customer attributes to power Retargeting / Remarketing campaigns across ad channels.

Creative Sequencing is a Paid Marketing approach that delivers ads in a deliberate order so the message evolves as a person progresses from awareness to consideration to conversion (and beyond). Instead of showing the same banner or video repeatedly, you plan a series of creatives—each one building on the last—based on user behavior, time, and intent signals.

Click Retargeting is a **Paid Marketing** approach within **Retargeting / Remarketing** that targets people who **clicked** on an ad (or tracked link) but didn’t complete the next desired action—like purchasing, booking a demo, or finishing signup. Instead of treating all exposed audiences the same, Click Retargeting focuses on a higher-intent segment: users who actively engaged by clicking.

A **Checkout Abandoner Audience** is one of the most valuable audience segments in **Paid Marketing** because it captures people who showed clear purchase intent—adding items and starting checkout—but didn’t complete the order. In **Retargeting / Remarketing**, this audience often performs better than broader site visitors because the message can be tightly aligned to a near-finished decision.

A **Category Viewer Audience** is an audience segment made up of people who visited a specific product category (or collection) on your site or app—such as “Running Shoes,” “Payroll Software,” or “Kitchen Appliances”—but didn’t necessarily view a particular product or complete a purchase. In **Paid Marketing**, this segment is especially useful because it captures **mid-intent** behavior: users are exploring a theme, comparing options, and signaling interest without committing yet.

Catalog Retargeting is a Paid Marketing approach within Retargeting / Remarketing that automatically shows people ads for the specific products (or closely related items) they viewed, added to cart, or considered on your site or app. Instead of building one-off creatives for every SKU, you connect a product catalog (a structured feed of items, prices, images, and availability) and let the ad system dynamically assemble relevant ads at scale.

A **Cart Abandoner Audience** is a group of people who added items to an online cart but did not complete the purchase—and who can be re-engaged through **Paid Marketing**. In **Retargeting / Remarketing**, this audience is one of the highest-intent segments you can reach because they already demonstrated clear buying behavior.

A **Burned Audience** is a group of people who have been exposed to your ads so often—or for so long—that additional spend produces little to no incremental value. In **Paid Marketing**, this shows up as rising costs, falling conversion rates, and sometimes negative sentiment. It’s especially common in **Retargeting / Remarketing**, where the same users can be hit repeatedly across placements and devices.

In **Paid Marketing**, retargeting is powerful because it keeps your brand in front of people who already showed intent. But it can also become wasteful (and annoying) if you keep showing ads to users after they’ve converted. That’s where a **Burn Pixel** comes in.

A **Browse Abandonment Audience** is a group of people who visited your site or app, explored products or content, but left without taking the next step you wanted (often a purchase, lead, or trial). In **Paid Marketing**, this audience is especially valuable because they’ve already shown intent—just not enough to convert yet.
