First; I would recommend SquareSpace [2] to anyone who wants to run a website with lots of features and easy as 1-2-3. It's extremely easy to use, and no HTML knowledge is required to start modifying the layout etc. (it helps if you do though).
With the website comes a management center (Dashboard) where you can view traffic/visitor statistics (among a dozen of other things regarding the website). Every now and then, I see the traffic increase.
Initially I thought;
Damn, they started the DDoS again....
After that;
They Slashdotted me (one can always hope)
Investigation of the Detailed Activity page shows that there a IP addresses that access dozens of (random) pages on the website within a couple of seconds. No ordinary user could click/surf this fast. Also, the user agent is in most cases IE6. All signs that this is the work of (search engine) crawlers / (spam)robots.
I noticed this weeks ago, and after that I got a bit suspicious on the validity of the statistics, so I started using Google Analytics as a shadow system in determining if it's a SquareSpace issue or not.
It turned out that the (unique) visitors are (almost) the same, but the pageviews are completely different.
Note that the the scale of the orange line (pageviews) has a different scale (on average; 1 visit = 1.42 pageviews), but even that it has a different scale the trend is easy to spot. Compare that to the SquareSpace statistics.....
I hope that they redesign the traffic statistics on the SquareSpace backend, since it paints a skewed picture on actual traffic on your (SquareSpace) website.
