Google Adwords or Yahoo Marketing?

Do you use Google AW or Yahoo for your PPC project?
I have some problem with Google, they always increase bid of keywords
Today, keyword has 0.1$ minimum bid
3 days after, you need 0.5$ to bid
and 7 days after, you need 5$ to bid.
And my keywords have status "Inactive for Search"
That 's exam only.
Anyone can explain for me about that?
With Yahoo, i didn't meet this problem.

 

I have been wondering this question for awhile, A lot of people have said that yahoo pays more, but i personally use google.

 

With adwords it has to do with your Ad quality score. That's why that is happening to you.

 

You don't get nearly as much traffic on Yahoo as you would Google. Google is the market leader and they can afford to charge more.

 

yahoo works so much better with me

 

I have to disagree. I get more from yahoo. Yes google charges more, thats why yahoo gives more traffic, more clicks for your money.
