The MSN adCenter Blog reports that a user encountered a snag with his negative keyword usage. Specifically, the snag involves an error code when you enter a negative keyword for a keyword that contains only an exact match bid.
A blogger by the name of Sudhir said this:
So what the error basically means is that “Negative keywords are only allowed on keywords that have a broad or phrase match bid specified”. If you try to add/update a keyword with “Not Keywords” and only exact bid specified then you would get this error. In my case this was being caused by a different scenario. We use Apache Axis for our webservice calls and Axis treats a blank string as a valid content string when compared to a null string. So even if the “Not Keywords” was set to blank it was generating the “Negative Keyword” soap element.
MSN adCenter says it will fix that error “in the future”. Meanwhile, take note, you cannot use negative keywords on keywords for which you have an exact bid only. But if you have bids on phrase match and broad match then it’s OK to use negative keywords at the pay per click advertising network MSN adCenter. I hope they fix that soon.
