I am bidding aggressively on the keyword "online widgets" on Yahoo UK and in the top 5. It's an expensive and competitive keyword.

Yahoo: 0.5% CTR
MSN: 10% CTR

I am getting as low as 0.1% CTR on some keywords, I am using standard match.

Note: We have one of the most competitive consumer offers at the moment, CTR on MSN is excellent, so why should Yahoo be so different?

Obviously the absurdly low CTR is killing our quality score, has anyone else experienced this?

Regards

Luke
