Retargeting Viewed Items

General

The Retargeted Viewed Items strategy is one of the product retargeting options within the product selection card in the campaign map, allowing you to re-engage users who visited the advertiser's website or app with products they previously viewed or interacted with.

This strategy allows you to tune how products are ranked for selection based on:

• Depth of funnel (how close actions are to purchase)
• Recency of engagement (how much newer actions outweigh older ones)
• Frequency of engagement (how strongly repeat interactions boost score)

Retargeting strategies rely on the Clinch website pixel or app events data sources that add product-related information to person or household profiles as users visit the website or app.

Prerequisites

• Enable User Profiling within your account's settings.
• Implement a website pixel or app events data source.
• Create a product feed and a product set within the feed for your account.

Configuring the Retargeting Viewed Items Strategy 

1. With the campaign map, add a Product Selection Card.
2. Select Retargeting Viewed Items as the product selection strategy.
3. Select a product feed.
4. Select a product set (an eligible subset of products to retarget).
5. Configure the following Advanced Settings:

Data Sources Selection - A filter to choose where engagement signals come from (websites and apps). All sources: broadest eligibility. Specific selections: fewer qualifying products → higher chance of Partial Success/Fallback. Engagement Funnel - A filter on which funnel events count as “viewed/engaged.” Items only qualify if they have at least one selected funnel event. Stages you exclude cannot contribute to the stage weight, recency, or frequency. For example: If you include only Details + Cart, then Search/Category views will be ignored completely. Activity Timeframe  - A filter that drops events based on engagement recency window.  Default: 30 days. Adjustable up to: 60 days. Smaller window = more recent intent focus, fewer eligible items. Funnel Events Weighting (Funnel Depth) Slider - How strongly deeper funnel stages dominate score. Sliding Right: deeper funnels dominate (Add to Cart / Checkout). Sliding Left: less focus on funnel depth i.e, upper funnel events such as Search can be equally considered as the deeper funnel events like Add to Cart. Engagement Influence over Time (Recency) Slider - How quickly engagement value decays with age. Sliding Right: Priority of events decays rapidly over time, therefore, recent events outrank older ones significantly. Sliding Left: Priority of events doesn't decay too much over time, so older engagements stay in consideration along with recent ones. Engagement Repeats Influence (Frequency) Slider - How much repeat engagements increase score. Sliding Right: Repeated views add a lot more weight. Sliding Left: Repeats add only slightly more weight.

Understanding the Retargeting Viewed Items Strategy

The Retargeting Viewed Items strategy works as follows:

1. Calculates the minimum number of products required by the creative.
2. If the user is identified, selects products that the user engaged with, filtered by Data Sources, Engagement Funnel, and Activity Timeframe.
3. Scores each eligible product using funnel depth, recency, and frequency (based on slider settings).
4. Combines all engagement signals into one final score per product, where the Frequency slider controls whether multiple engagements add up or the strongest single one dominates.
5. Ranks products by final score and selects the top products to display.
6. If fewer than what is required by the creative qualify, returns what's available as Partial Success; if none qualify, returns the Fallback output.
