More conversion rate graphs

If you go to Goals,
Click on any Goal
and then view the conversion rate graphs that show your conversion rates over time, this is good start.

I can demonstrate that this data is very noisy until you can filter by "Searches" or "Keywords"

For example, if you get a ton of social media traffic for a period, or show up in the news, or image search, email, etc... for terms or events non-central to your main business, then the conversion rates appear to plummet.

Of course, adding more things like Source, Engines, etc... could also be really useful.
