I did some research on the Google PPC, Adworks. Here is what I found out and did. There are certain keywords that a mass market for Muds don't use. I think it has more to do with folks not wanting to spend the money on it than anything else. Certain words don't have a lot of ads attached to them. So, I put an ad out there for us on google using these keywords.

mud
muds
carrionfields
carrion
fields
rpg
multi user dungeon

I set the buget really low, just to see how many times it pops up when I use these target words. I think that we can get a lot of use out of this. First thing, don't click on the ad when you see it. The budget is low for a reason. Google doesn't have a lot of advertisers using these specific key words, so the price per click will be low. Now, they want to show potential clients that they have a lot of ads to generate more funds. This will give us a lot of visibility for a very low cost.

Go ahead and use your google search for these keywords separately. See how many times the Carrionfields pops up. Do it repeatedly. But, don't click on the ad! I want to see how many days we get for the amount I set.
