It looks like visitors to the Resolver Systems website are predisposed to clicking through the tabs at the top of the page, from left to right. Does anyone else see this kind of thing?
Here’s the full dataset. Each line below shows a Google Analytics overlay, which tells you for each selected tab what percentage of people clicked on each of the other tabs during July 2009:
It looks like we managed to break tracking of access to our “About us” page for that month, so I put the results for that tab aside and did a bit of simple statistical analysis (in Resolver One, naturally) on the remaining data. The results:
The “from” tab is top to bottom, the “to” tab is left to right — so, the chance of someone who is currently on the “Buy” tab clicking “Download” is 29%. The average chance of someone clicking on a given tab across all sources, and the standard deviation of those figures, are summarised at the bottom. Each cell is coloured based on how many standard deviations from the average it lies — if it’s more popular than it normally is, it appears red, if it’s less popular it’s green. The intensity of the red/green is based on how much more/less popular it is.
I think there’s a very clear pattern — the line of red starting at the “Home tab to Buy tab” cell, and going down and to the right to the “Screencasts tab to Get help tab” cell. That indicates that people are significantly more likely to click on a tab when it’s the one to the right of the one they’re currently looking at.
You can download the analysis spreadsheet from here, and if you don’t already have a copy of Resolver One to run it on (shame on you ;-), you can get an eval version here.
This is interesting — is it just our visitors, or have other people seen similar results?
