I believe this is the list that we find on the Eshop when you click on the "best sellers" section of it.
Unfortunately, every region has its own rankings on the Eshop. It doesn´t track worldwide sales, but only regional sales.
It would be great if Nintendo actually provide some numbers. We can have a small picture of actual sales by looking at the evaluations quantity, at least we can tell the titles that have better lifetime sales, but still it´s just not enough information
