Joe,
I understand entirely and I don't mean to lay false claims out or anything of the sort.
I'm trying to find the time to finish the "whitepaper" of sorts that actually brings about the correct context and justifies the numbers better than, "Hey look at this chart". There's many factors involved and we track every change and how it impacts things.
The charts I use are always organic traffic because paid traffic doesn't show anything about website performance unless you're looking at pages/visit or other metrics. The problem is that I don't necessarily have all the answers to explain the performance.
I can't give you the names of these stores because I don't have their permission yet, but all 3 are from the same Automotive group. All 3 moved from the same old platform to our platform. One switch over in late January and the other 2 switch over in March of 2013. All 3 had different OEMs, different target markets and 2 of them are from completely different locations.

Obviously these charts aren't enough information, which is why I'm working on an actual document that pulls together all our in-house analysis and reasoning behind each change, the results we saw, etc. If I had the document today I would share it.
This site is our poorest performer on the organic front. I can't explain why necessarily, but they have historically been a poor performer and we weren't able to fix everything about that with just a website. The major dip just past July 2013 was a lack of analytics - someone made a mistake and the tracking code was removed for a week or so.
We also have all the other metrics to show year over year, month over month, change in # of page views, etc.
The insight has helped us to make every decision that we make. We noticed an increase in bounce rate correlated directly to an increase in what I call "Unassociated Organic Traffic" - traffic that wasn't necessarily looking for what we're offering tends to have a higher bounce rate, but for some reason the sites rank for things that don't necessarily apply. The blogs tend to add to this as well.
I'm more than happy to share information, but I only have so much time in a day to prepare this paperwork while still continuing to do my job. We're not a huge team yet and we all have plenty on our plates.
