Accurate recommendations can increase sales dramatically.

All current wine recommendation methods fail miserably. That’s why people leave wine clubs or don’t drink it at all because they can’t consistently find wine that they like

However, if you the math from the examples below, you can see how decent recommendations can drive sales.

Only 7% of people click on a recommendation. But that 7% drives 26% of revenues (35% if you are Amazon.)

That means that an increase of 1% in an accurate recommendation can increase sales by 3.7%. This is a revenue booster that requires no increase in out-of-pocket expense.
