Google Analytics – take daily with a grain of salt

Haven’t messed with Google Analytics in literally years, but since I’m getting a new site up I logged in. I noticed these spikes on all of my accounts for different sites, even sites that do not exist anymore:

Most of the traffic was from Great Britain. I’m sure there’s an explanation… that I don’t have the time or motivation to uncover.

My point is – approach your analytics data with a touch of healthy skepticism.
