Have any of you noticed that sites with certain colors make mire money than other sites? My main site was a blue theme until recently and I changed it to green with brown... a little easier on the eyes. Time on the site for my viewers has gone up, adsense CTR has increased and CTR for Amazon, Clickbank and CJ has also been better. It's only been a couple of weeks so my data is a little light but I would like to hear the thoughts of some of you other marketers.
I'm sure it can have an impact. Most of the research related to landing page optimization indicates that colors do matter, but it would be hard to accurately test while holding all other variables constant. I'd be interested in what others have to say...
