Like clockwork my site has had a predictable traffic pattern with a predictable low traffic day(Saturday) and that has evolved very slowly. e.g. several years ago Thursday was the low traffic day, then Friday and until earlier this month Saturday. The pattern repeats, even as reported by GWT, where the day before and the day after the "low" day are also lower than the rest of the week, resulting in a chart with a sawtooth appearance.
The teeth have changed abruptly this month. The "low" day now lasts two days, Saturday and Sunday, and the drop preceding it also lasts two days (Thursday and Friday) while Monday, Tuesday and Wednesday remain the same. My peak days in traffic from Google.
The question is why. Thursday to Sunday is the prime shopping time so is Google sending me fewer visitors during this period or are shoppers surfing less during this period or... something else entirely? My site is informational so perhaps I'm being shut out of more prime shopping time traffic? Perhaps people just don't browse as much during the weekends?
I would assume that shopping portals and sites would have increased traffic from Thurs-Sat would they not? Just curious as to your thoughts on this and to know if your daily traffic patterns changed in May.
