The latest research out of the States estimates that nearly half of all search budgets are wasted on companies bidding on their own brand name or product names.
“The reality is those people are already intending to go to your Web site,” says Young-Bean Song, from Atlas. “What you’re really paying for is a glorified Yellow Pages listing.”
Interestingly fhe report also cites a recent experience of eBay - they stopped advertising with Google for 10 days in June. While they saw less traffic from Google, their overall traffic was not noticeably impacted. I bet Google aren’t passing around the results of this little test!
While I admit that I still make a habit of bidding on certain branded terms and products, I keep bidding to the bare minimum - especially in cases where the natural search ranking is high. If your IP is well protected then it is unlikely that competitors will bid on your brands or keywords anyway.

yes i must confess that i was paying . more but ill be looking forward in this case too .
