Microsoft Bing adCenter Desktop Duplicate Keyword Error
Posted on: July 28th, 2010 by Kelly SpryszakIf you advertise on MSN’s Bing and use the Microsoft adCenter Desktop, you have probably run into errors when attempting to sync your account. These issues typically come after adding new keywords to a campaign and can be extremely frustrating to work through. The most common error we have seen here at JumpFly is that there are duplicate keywords in the account. We search and search but can never find these alleged duplicates. So, we did some research and found out some useful information about what MSN calls “Normalization.”If you use Microsoft adCenter Desktop to manage your Bing PPC advertising, the following information may be useful:
When working on Microsoft adCenter Desktop, have you ever attempted to “Sync” your account after adding new keywords to a campaign, only to receive an error that there are duplicates in the account?
I receive this error quite often, but in my case, it is not a matter of adding two of the exact same keyword. Often times, it is because I am trying to enter two forms of the same keyword that the Microsoft system has “Normalized”.
Normalization is the process by which Microsoft adCenter removes extraneous characters from user queries. An automatic scan finds and removes duplicate forms from the search query to help minimize redundant content.
For example, let’s say you are trying to add the following keywords in your account:
“jump fly”
jump & fly
jump fly/
jump-fly
jump’s fly
the jump fly
Each form of the keyword ‘jump fly’ above will be normalized to be read by the system as ‘jump fly’.
After attempting to sync your account with these new keywords, you will get an error message telling you that you are trying to create duplicate keywords, even though visually the keywords are very different.
Don’t get frustrated, here’s the explanation from MSN. If you are looking for the latest release notes on what changes have been made to the adCenter Desktop tool, you can find that here.

Microsoft already registered several variations of this URL in other countries, including “bing.com.au”, “bing.co.nz” and “bing.co.uk.” Furthermore, in March,
shares (about 5.5% of the company). I saw a recent presentation he made where he stated that he continues to believe Yahoo shares are undervalued, but admits that he also thought they were undervalued when he was last purchasing shares near $25 per share. So far, he is down about $1 billion on his investment. Ouch! He is still looking for some type of partnership with Microsoft on their search efforts which he believes could help save Yahoo a great deal of money. While there are no alleged talks going on at this time, I suspect these two will eventually work out some type of agreement. With Yang stepping down and both Icahn and Microsoft’s Steve Ballmer expressing interest in a search deal getting done, I think something will eventually develop. I would also like to mention that I very much hope that Carl Icahn is a better investor than speaker because quite honestly, listening to him speak was a little painful. Sorry Carl, but it’s the truth.
