Below I have listed a series of prominent, politically-oriented websites, and compared them on their ability to retain traffic in the post-election environment. The way that I have calculated this is to take the 1-week average daily reach number from Alexa.com (representing post-election traffic) and divided it into the 3-month average daily reach number for the same site (representing -- principally -- pre-election traffic from the convention period onward, the juicy part of the four-year election cycle). For instance, Slate.com has reached 598 out of every 1 million global internet users on an average day in the past week, as compared with 892 on an average day over the past three months, for a retention percentage of 67 percent.
TheAtlantic.com 125%Any number of caveats apply -- including that Alexa.com estimates are usually pretty blunt insturments(although they're a little bit better for relatively large sites like these). But you see the sites running along something of a spectrum from campaign-specific to general political (and sometimes cultural) interest.
Our retention percentage is 59 percent, which I'm actually very, very pleased with. Thank you for visiting us during the run-up to the election and thank you for continuing to visit us now. I haven't done one of those "what's next for FiveThirtyEight" posts yet, but I will do so soon; rest assured that we are in this for the long haul.
