I got a bid from Kobo today to put my books in Kobo Plus so I checked an earlier thread here. Kobo Plus apparently counts the minutes a reader spends on your books and then does some of what Amazon does with splitting a pot.
The problem is if you write fast-paced stories your minutes will be low, and you won't get much of a payout. My books are heavy on dialogue and I could see ending up with very little in the way of payment.
However, I'd be interested to hear if anyone gets more reads on Kobo Plus than sales of any particular genre. For instance, if your romances don't sell on Kobo but do make a few cents on Kobo Plus, that would be important information. Likewise, assume your science fiction does sell on Kobo, are you also putting it in Plus?
