Change Keywords

[Pagerank]

This is extremly disapointing, below is my adsense for this month so far.

Clicks: 106
Earnings: USD10.19!

I think i need to change my keywords as all the keywords are MMORPG related. I remember ages ago Alan created a Google code insert to change the keywords but im sure it didnt meet the standards of Googles TOS.

I drasticly need to change my keywords. I have a file host with the following stats:

Clicks: 10
Earnings: 2.18!

Im unsure how to go about doing this but it needs to be done soon.

Thanks for any input in advance.
