The price against the same variant in other stores and, where we are licensed to keep it, its own price history.
- Warranty & returns15%
Who provides the warranty, for how long, whether it is valid in your country, and the return window.
- Delivery10%
Availability, who ships it, and the delivery promise.
Commission is never a ranking input
Commission is never a ranking input. What a store or affiliate programme pays Siftela has no effect on the order of products or offers, or on which one we call the Siftela pick.
This is enforced, not just promised: our database rejects any ranking feature whose name, or any field it reads, looks like commission, CPC, payout, EPC, affiliate, bounty or revenue, and it requires the active weights to add up to 100%.
The Siftela pick
On a product page, the Siftela pick is the highest-ranked offer you can buy now. On a category page, it is the product with the highest score, no knock-outs, and at least 4 out of 5.
