A Search Engine Watch Forums thread begs the question, can the price increases seen at Google AdWords have an impact on the prices at other PPC engines, such as Yahoo! Search Marketing?
The logic behind the question is that while some people bids rose from a few cents to a few dollars, they may not be willing to spend that much. But they may be willing to spend half of that much. If so, would they decide to increase their bids at Yahoo! to achieve higher placement, just because they know they can?
grnidone rationalizes, "It seems that perhaps some people may not want to pay $5.00 a click base price for a google ad, and instead made their Yahoo ads more competitive."
However, he said based on the data he has seen, the price changes are a "mixture" and there is no pattern to prove his own theory yet. He would like to know if others are seeing such patterns or not. Could be interesting.
