The company I webmaster for has 11 sites. One for itself and one for each of is subsidiaries. I have been noticing that for the past year Tuesdays have consistantly been the peak day of the week for traffic. Week after week without fail.. Has anyone else noticed this on other e-commerce sites???
tues if best for us with slow decline over the last days of the week, then a more significant fall to around 66% to 50% for Satruday. Sunday is slighly better but that is because for guys in OZ, NZ and Asia it contains several hours already well into their working days. Monday is usually second best. I guess the downward trend is the substantive one, as Mondays for us takes into account for us a fair few hours of very early Monday hours for North Amercian users - more like a weekend.
For us it just depends on when we send out our weekly newsletter... Right now it's Friday - #2 (when we send out our email) and Monday - #1, for all of those opening them at work.... Tuesday is third...
During summer month in the US, I see Tuesdays peak, probably because of weekend vacationers taking and extra day away from home and work. The rest of the year I see Mondays and Tuesdays rating about the same ... they are the peak days of the week.
