Abstract:

When it comes to online advertising, one of the tools your competitor has may be your company's name, trademark or service mark. Google and Overture allow advertisers to purchase company and product names as keywords in pay-per-click campaigns. This allows companies to poach potential customers from their competition by having their ads appear whenever a consumer searches for a competitor by name.
