Submitting New Keywords To Adwords

If I am submitting hundreds of new keywords to Adwords each week, is there a tool that will notify me of duplications?

or do I have to take my new list and check my existing list one by one?

thanks

I'm not aware of a tool, but what normally happens is google will only serve one of the duplicate terms so you'll see one of them not getting clicks, and you should be able to weed it out that way.

It's really not too hard though to drop all your old and new keywords in to an excel sheet then sort by the keywords, that way you can de-dupe the list quickly before you drop them in.

I think you need to syndicate the list so keywords will not be duplicated . Also make a Unified keyword list so every time you add new keyword you just need to compare the list which I think just a click working if you are good in Excel.
