How to Create a Product Line

A product line is a group of related products sold under a single brand by a company. 

Benefits of a product line 

• A product line enhances a business' chance of having long term success. For instance, a product line creates more opportunities for increasing the customer lifetime value (CLV), ie the among of money a customer spends over the period during which they remain an active customer. 
• Once customers already know and like your brand, marketing all the other products within the product line becomes easier than selling new stand alone products.

How to create a product line

• Decide the focus of the product line. An example includes a specific deliverable perceived customer value to a specific market profile. It  may essentially be the unique  value proposition for that collection of products. Whether it is published, this focus should guide all of your product mix considerations. After all, customers buy benefits and not the physical product or service. For instance, one skin care product line may focus on anti-aging while another may focus on detoxification. This statement may be something like the following. "The [product line X] offers [product x] for [target market] to [unique value proposition]. Unlike [the alternative], we [competitive advantage]".
• Add interrelated versions of the central ideal of the product line. Each variation should be similar enough to be clearly recognizable as being part of the single product line. The differences in the variations should have some justifiable reason like specific customer pain points withing the overall central idea. For instance, your anti-aging product line may include variations for 1) age spots, 2) re-hydration and so on. 
• Add different products that complement previous ones, even if those other products are very different. Consider the circumstances in which the product will be used and the customers' needs. For instance, if you are selling sunblock, you can imagine the customer is likely to use the product in a sunny location. Consequently, you may also be able to sell eye shades. For instance, customers using the age spots variations of the product may be happy to buy a floppy hat to protect them from the sun.
