Hi Ron, in my workplace we use control charts quite extensively on information centres. Being an operation which operates a continous process; having the relevant personnel hand update these daily is a powerful way of ensuring that key metrics are reviewed each shift. The challenge is setting the upper and lower control limits, and then continuing to challenge these if the targets are always being met and there is opportunity for further improvement

You could always do a quick test, and put the old version up for a week to see if your conversion rate drops as would be expected. That would serve to confirm your suspicion that the design change was effective. If the rates stayed steady, it would point toward a different factor.

Hi Chris, I checked to see if there was any correlation between my website traffic and the increase in downloads and there wasn’t. My traffic, almost since the day I started this blog, has slowly increased month after month… but no where near the percentage increase I saw after the design changes.

So, I’m pretty confident the design changes are in fact the red X.

Nothing to do with external things like Presidential Election Results?
Articles in the news about how well Toyota was still doing in spite of downturn in car markets especially compared to the Detroit Three with their hands out?
Did you move up higher on Google’s hit list for some reason?

Lots of factors… and no good way to find the “Red X”.
