Were always into a good conspiracy theory – who isn’t? But this one about Google is a corker!
One webmaster over at Webmaster World has a theory that for some sites, Google may give the site higher ranking based on what day of the week it is.
The webmaster has been tracking his traffic from Google for a number of months and has discovered a pattern. Here is a rundown on the discovery:
I have a site that shows a saw-tooth graph in which weekly traffic peaks every Tuesday and is lowest every Saturday, the graph shows a steady increase in traffic over time but the same pattern holds steady for at least 8 months.
I’ve been keeping track of what’s indexed in Google and I’m finding that the site has the highest number of pages indexed on Tuesdays and the lowest number on Saturdays.
It looks like the sites rankings, both in position and in quantity, drop every Saturday and rise again quickly on Tuesday.
You can read more on the theory at the Webmaster World forum here.
Now here’s were it gets interesting… after months of tracking a few days after the webmaster announced the discovery, everything changed. He said:
Final update, just when I thought I had sufficient data to start tracking related considerations for effect Google changed gears on me, Today’s traffic should have been trending downwards until Friday (though up from last Wednesday) but instead the site enjoyed a record up day… breaking a long running trend.
So is this just coincidence or is something more sinister going on here? Have you experienced this with your site? Feel free to share your thoughts below.
