Over last few months I have noticed a patern to hits on my blogs. not only on my site here but on other sites also. Below is the typical graph I get for one blog post after it has been posted.
What looks to happen is after posting it either though RSS feeds, email updates or following a tweet about the new content every hits the page on the first days or so. This graph as the title of the blog suggests is a mathematical formula X^-2.
What is interesting is when you apply this to a site that posts new content everyday but none at the weekend - you get peek traffic on Wednesday due to the overlapping trends as shown below.
These graphs assume that each blog is of equal interest and the same amount of people come back each time. We know however content will differ in interest and that Fridays have a drop off more than shown here - why? Well there could be lots of reasons but you will find that traffic shape is more 'bell' shaped. I could also suggest that if you post on a site that has lots of other bloggers, then Wednesday could be your best day to post. But don't tell everyone as they will all do the same.
I'd like to hear if you have seen the same trends or have reasons for the drop off on a Friday.
