Cost Per Keyword (CPK) on the Rise

Interesting article over at eMarketer on the Cost of Keywords which has this interesting graph that plots what advertisers are paying for keywords.

What stands out to me in the graph is obviously December but also the difference between this July to September and July to September of 2004 where there has been a significant increase in what advertisers are paying.

I’ll be interested to know what this December’s graph looks like. I’ve noticed in this past week a marked increase in my average cost per click on Adsense.

Thanks to Tom from Scared Monkeys for pointing me to this article via email.
