Talking about plugins and features for web shops, a good idea is to have a feature saying "Based on this product, you might also like these products: list of products".
The "You might also like"-feature is about statistics and correlations telling you that "People who buy this product also tend to buy these products"- products that might not be related at all.
I'll be having a speech on digital marketing, for a potential customer needing assistance on web shop improvement. For that case I'm looking for a shorter term for the above mentioned kind of feature. I believe I once heard a shorter term for it, but I forgot it :(
