Product segmentation
Also known as: Catalog segmentation
In short
The process of dividing a product assortment into groups using shared attributes, business rules or measured performance.
Give different products a clear treatment
Product segmentation organizes an assortment around a decision. A team might separate items by category, stock position, margin band or recent performance. Each segment needs a clear membership rule and a reason to exist.
Campaign product groups are one implementation. Google Ads can organize products using attributes such as brand, product type and custom labels. The segment describes the selection; the campaign’s settings determine how it is advertised.
Segments may overlap. A bestselling item can also be seasonal and low in stock. Decide which rule takes priority before using several segments to control campaign inclusion.
Illustrative example
Imagine a retailer reviewing sales over a defined 30-day period. It groups items into those with enough orders to evaluate and those with insufficient evidence. Within the first group, it considers margin and stock before deciding what to promote.
This is an illustrative decision process, not a recommended threshold or a promise of better results. A new product with few orders is not automatically a poor product.
Match the rule to reliable data
Keep the measurement window, identifier mapping and update schedule explicit. Stale stock or mismatched sales records can put items in the wrong group. A more detailed segmentation is useful only when the team can act on it and maintain its rules.
