Kelkoo is a great advertising channel for retailers who want to sell products in Europe.
Creating a Kelkoo feed is a little different than creating one for other channels like Google Shopping. You can create a Kelkoo feed in either XML or CSV format manually, but the Kelkoo feed specifications have quite a few attributes to be optimized.
Many of the Kelkoo feed attributes are very important from a relevancy perspective, especially the title and description.
