What do product line effects refer to?

Product line effects refer specifically to the impact that promotions or marketing activities have on related products within the same product line. When a company promotes one product, it can influence the sales of other products that are in the same line. For example, if a brand has a line of shampoos and runs a discount promotion on one particular type, it may also boost the sales of other types in that range, as consumers may be inclined to purchase more items within the same category.

Promotions can create a halo effect where increased visibility and consumer interest in one product lead to heightened awareness and sales of other similar items. This interconnectedness is a vital consideration for marketers when strategizing about promotions and product placement within a brand’s offerings.
