Yahoo Japan has just announced that they are going to change Min CPC decision system for keyword bidding.

1.The system is going to be similar to Google. (In FAQ, somebody has been asking if it is going to be the same to Google system or not)

2.Currently the Min CPC has two different type of prices, 9 yen (about 0.04 GBP) or 35yen (about 0.19 GBP)

3.From sometimes in August, Each keyword Min CPC is going to be different and the lowest is going to be 1 yen (0.005 GBP)

4.They will give us allowance time before they would stop a keyword if min bidding was lower than Min CPC Yahoo requested and give us alert to change.

We should more pay attention and time to care about each keyword bidding although taking long time to bid by site even now!

I will post if further information.
*Not sure if it is for other countries' Yahoo Search Marketing.

Thanks
