The seller in this auction thinks we're all stupid.

Look at those impressive traffic stats! 11,570 unique visitors per month is a very nice amount. I'm interested!

But wait. Look at the date range selected in the Google Analytics screenshot.

Unless I'm very much mistaken, the seller has selected a time period greater than a month and slapped the stats for that period in their auction details. Last time I checked, Feb 2 - Mar 10 was more than a month. It's not even a leap year or anything! Naughty naughty.

But the crime isn't limited to using a time period greater than a month. Look at the graph in those traffic stats. The seller is taking full advantage of a spike in traffic they had over a month ago. Of course, if they were presenting the last 30 days worth of traffic, we wouldn't be able to marvel at that huge traffic number.

Also, this spike is due to the product launch and associated promotion undertaken by the seller. But you can't do a product launch every month, so you shouldn't expect similar traffic levels every month.
