Average cpc increased from .16 to .44 yesterday for the same position 1x my max has been .50 for last two month.

min bid changed from .05 to .04c and no new competitors plus for all 6 ads the order hasn’t changed.
By the way my CTR hasn't change and it is very strong: 10.87% for last two month and yeasturday. this is for search only, content has not changed.

I really don’t appreciated it.

Any comments what could possibly change?

Your CPC is determined by the bid of the advertiser below you. Maybe that advertiser increased his bid enough to bump up your cost but not enough to position his ad above yours.

Im not sure what happened with this update from adwords from last night but all my 243 keywords are currently inactive!

On average i suddenly need to increase bid from 5 Cents to 15Cents.
For allot of keywords i went from $0.05 to 4.00$ :o

What could be the reason for such a extreme increase in cpc for over 240 Keywords!?
