The recently released Google Adwords Editor (beta, of course!) is really cool. It lets you edit all your Adwords campaigns, text ads and keywords in an easy-to-use desktop application. If you are changing your ads and keywords often, you should definitely look into using the Adwords Editor, as it’s much quicker and more responsive than the web interface.
It would be nice if MSN had a similar tool. It would be even better if you could synchronize ads and keywords between MSN and Google. Or if you had a single desktop application to manage all the different systems – complete with reports and statistics. Is this a Micro-ISV opportunity?
