I came across this tool online, it's like splittester but it's automated, and help with people (like myself) running multiple campaigns and have to manually check each one. http://adwords.clickmuse.com/ Hope you guys find it useful.
I think not. "What information do we collect? For the ClickMuse AdWords Optimizer we may collect your name and email address when you first register for the service. We may also collect Google AdWords reports that you send to your personal ClickMuse AdWords Optimizer email. " I'd advise against handing over your AdWords data to this group. I have a hunch NicholasC "came across the tool online" because he works there.
On the website itself, it's stated that they understand that keyword data is very sensitive to the publishers (like us). So there's away to not even give them that data, and you can still receive your reports. Just that by not giving them the data to parse, you have to compare the email report' s "Ad 1" to your google adsense account to see which ad is "Ad 1". I'm helping to promote Clickmuse and the optimizer, it's not a commercial tool, there's no money involved.
Also, the team that made this are heavy adwords users for over 2 years. In that 2 years, they have spent so much time manually. Like myself, I have many campaigns. So they made this for themselves, but seeing it's such a good tool, they decided to allow the public free use to it. There are NO KEYWORDS sent to their servers.
