Do we as a consumer need to be told what to buy? Or do we rather want to be told what we are buying?
This theme was examined in a previous post titled You Must Supplement Customer Insight with Rich Product Data.
Not at least on the European scene with the upcoming General Data Protection Regulation (GDPR) there are limits to how long you can go in profiling your (prospective) costumers. And I am sure those people will value more you are telling them the complete story about your products, rather than guessing what products (from your range) they might need.
As a consumer, we want the facts about the products to make a self-service purchase. We want to be able to search for and navigate precisely to a product suitable for a specific use. We want the facts in a way, so we can compare, perhaps using a comparison service, between different brands and lines. We want to know what accessories goes with what product. We want to know what spare parts goes with what product.
By the way: Business buyers want all that too. And a person being a business buyer is a person (data subject) in the eyes of GDPR too.
For providing complete and consistent product data you as a (re)seller need to maintain high quality product data and if your product portfolio is just above very very simple, you need a Product Information Management (PIM) solution and, if you have trading partners, you need a PIM-2-PIM solution to exchange product information with your trading partners.
