To show your item as the sponsored product in any search result you must select keywords and set a commission bid higher then anyone else for that keyword. You can add multiple keywords by seperating them with a comma, however you can only set one commission rate, so use the search keyword tool and set you commission rate to the highest value return to ensure you show up on all your keywords.
The keyword search feature shows you the current bids per keyword you need to outbid in order to be the sponsored product.
The commisison is paid by the seller to OTTCoin whenthe sale occurs.
Example if you have a commission rate at 10% and your product price is $3000 you would recevie $25.50, 10% would be sent to OTTCOIN as well as the .05% instant transaction fee.
So the highest bid you could ever offer is 99.95% to account for the transaction fee.
