I've been using Adwords editor to make adjustments to multiple campaigns across several accounts. What I don't like is that I'm viewing data only in static "snap shots" of time- be it daily, weekly, etc.. What I'm loosing is the effectiveness of these ads over time. I like the graphing available through adwords interface reporting, however, running a seperate report per keyword say over a month to see trends and then matching up with edits performed is seriously time intensive. A product, Adwords Dominator, has an interesting graphing feature per keyword, and I gather it would be possible to replicate using API.. But I'm wondering if others have searched for graphing solutions and what our options are. thanx.
Set up a report to e-mail you your weekly data every Monday, and dump it into Excel. As well as allowing you to draw graphs, it's quicker, and more flexible for analysing your results - i.e. what's working or not...
