As of March 3, Bing and Yahoo will change their policy to allow the use of trademarked names as keywords in search ads. They say the change will bring their policy “in line with search industry practices” and some outlets say this is due to Google’s hard won victories in court over such matters.
Here’s the wording straight from Microsoft Advertising:
“As of March 3rd, Microsoft will cease editorial investigations into complaints about trademarks used as keywords to trigger ads on Bing & Yahoo! Search in the United States and Canada. If there is concern that an advertiser may be using a trademark keyword inappropriately, the trademark owner should contact the advertiser directly.”
