Making Cash On The Web is a serious attempt to compile useful information about making money on the internet. It is a combination of things that I have learned myself, as well as information culled from other sources. It is NOT about get rich quick schemes, or wierd marketing programs. I am not going to sell you anything.
Pixelfast offers a free tool to help you research the prices that advertisers are paying for clicks. It queries the Overture pricing tool and presents the information in a usable format.
To find out what various advertisers are paying for clicks for different key words, try the Overture Bid Tool. You can type in key words, and Overture will tell you what the current bid is.
Of course, this tool only gives you the pricing for Overture, but it’s probably save to assume that prices are similar on other programs such as Google Adsense.
