Dynamic Product Tagging

5 min. readlast update: 09.01.2025

Automate how you categorise, segment and sync products to Shopify based on performance.

The Dynamic Product Tagging feature allows you to set powerful, logic-based rules that automatically classify products and variants into custom metafields in Shopify. This helps you streamline merchandising, promotions, and campaign targeting without needing to manually manage tags.

Overview: Product Tagging Rules Table

From the main screen, you'll see a list of existing tagging rules for variants or products. Each rule includes:

Column Description
Metafield Name The label that will appear in Shopify (e.g. A Class, New Arrivals)
Metafield Key The internal identifier (e.g. a_class, new_arrivals)
Metafield Value The value that gets applied (e.g. “A Class”)
Lookback Days How far back the system analyses data to apply the rule
Shopify Type Usually set as PRODUCTVARIANT
Created At The date the rule was created
Actions Click icons to view, edit, or delete the rule

When to Use This Feature

  • Automate tagging of high-margin items, new arrivals, dead item or seasonal collections
  • Sync product performance data with front-end Shopify logic (e.g. feature A Class on homepage)
  • Build smart collections or automated discounts based on metafield segments
  • Identify and exclude low-stock or low-ROAS products from live campaigns

Variant 1: A Class

A Class products are considered “Winners” in your product portfolio. These are your top-performing items that consistently deliver higher profit margins relative to other products in your mix, strong sales velocity, and reliable demand.

They are typically:

  • Highly profitable – strong gross profit and contribution margin
  • Consistent sellers – frequently purchased and low return rates
  • Core range items – essential to your brand’s performance and marketing strategy

 

When setting up your A Class tagging rule, you have the option to define exclusion conditions to filter out products that should not be considered, even if they meet your main profit criteria.

In the case of A Class, the exclusion rules are as follows:

  • Inactive products
  • Gift cards 
  • Stock on hand less than 1
  • Product type exclusion aka engraving or shipping protection as common examples
  • Refund rate greater than the store average 

These conditions use “OR IF” logic, meaning if a product matches any of these exclusion criteria, it will be excluded from being tagged as A Class — regardless of its performance.

Additionally, you can further refine this tag in the Set Rules for Value. This is where you define what qualifies a product as "A Class".

  • If Product Gross Profit Class is Equal to Winners (A)

You can add more logic using AND / OR to refine your criteria.

Variant 2: B Class

B Class products are considered “Contenders” in your product portfolio. These items show solid performance in terms of profit and sales but haven't yet reached the consistency or margin strength of your A Class (Winners) products.

Variant 3: New Arrivals

The New Arrivals variant tagging rule allows you to dynamically identify and label new products based on Shopify collection data and stock status. This keeps your merchandising current without manual tagging.

 

In this context, a New Arrival is defined as any product assigned to the "New Arrivals" collection in Shopify within the last 90 days.

This rule helps you:

  • Automatically update new inventory as it’s launched
  • Feature the latest products on landing pages or home banners
  • Align email and ad campaigns with current product drops

 

There are many other rules you can set up:

  • Last variant in stock 
  • High ROAS
  • Low ROAS
  • High AOV
  • Underperformers / Zombies

There are also many other exclusion rules you can set up:

  • Size curve availability
  • Low AOV
  • High track cost (CPC)

 

💡Dynamic Tagging Campaign Ideas:

 

Campaign Structures

  • A Class GP Campaigns
    High spend for high-margin, high-sales-velocity products.

  • B Class GP Campaigns
    Medium spend for lower-margin products with strong sales.

  • C & D Class Campaigns
    Tight spend for low-margin or underperforming products.

  • Zombie Campaigns
    Focused on D Class products with very low traffic (clicks) and/or sales volume.

  • % Tier Campaigns (Gross / Contribution / Net Profit)
    Used when brands have large margin variances between categories or large inventory bases.

  • Clearance Campaigns
    Always-on, tight-spending campaigns for low-margin products that need clearing.

  • Fringe Size Campaigns
    Targeting products with low size curve/variant availability, aiming to clear remaining stock efficiently.

  • Minimum PROAS Campaigns
    Campaigns optimised for Gross Profit on Ad Spend, ensuring profitability thresholds are met.

Considerations for Exclusion

When setting tagging rules, exclude products that are unlikely to perform well in ads or that brands prefer to clear through other channels:

  • Low Size Curve / Variant Availability
    Products automatically untag themselves when stock is too limited, then shift into clearance/fringe-size groups.

  • High Return Rate
    Exclude items with consistently poor customer retention.

  • Minimum Sold Quantity Thresholds
    Prevents high movers from falling into lower brackets (and vice versa).

  • Last Remaining Variants
    Avoid advertising when only one or two variants remain in stock.

  • Minimum Quantity Rules
    Some brands prefer not to advertise last units, instead discounting and clearing via EDMs (email campaigns).
