So, I am in the midst of creating an excel spreadsheet that would track changes to my PPC campaigns. And that got me to thinking. I am certain that there is something already out there that does exactly that and is probably much better than what I want to create..... Anyone know of a free or for-pay program? Basically, I am looking for something where I can put in information like: clicks, impressions, CTR, cpc, cpm, etc... and then do a change to a campaign/keyword/adgroup, then after a certain number of days or clicks, evaluate the effectiveness of the change. This might sound really basic to some of you, but I am new to online marketing... Thanks in advance
