I'm looking for something that can simplify all the data in my Adwords account (as I'm not an Excel Geek). Anybody tried Adwords Reporter or can suggest other software which makes it easy to track past performance of campaigns/adgroups/keywords with ease?
I would suggest you use the reporting tab within your adwords account - this should do everything you need it to. You can target which stats you want to track very specifically there, you can even get it to run a scheduled report automatically and have it sent to your email address.
