Yahoo has decided to drop some knowledge on Yahoo Search Marketing advertisers about a tool it has that it says will speed up their campaign optimization.

If you are not familiar with it, its called the Bulksheet.Yahoo describes the tool as simply a spreadsheet with specialized fields that allow you to modify campaign, ad group, keyword, and ad information. Yahoo says it makes tasks faster and simpler than they would be in the Sponsored Search user interface. The reason for this is that you can make changes and upload them at once.
