Google, Yahoo and Microsoft have teamed up to fight click fraud. Ask.com, LookSmart and Media Rating Council will also be involved. Their goal is to find a better way to identify and measure "click fraud."

But this is an issue that could be harmful to all of them and by working together they feel they can better solve the problem.

One of the first things they will need to do is to come up with a definition of click fraud. They will then come up with guidelines.
