We've all got them, so why not share them? The sometimes unorthodox ways that people find your hubs. Non sequiturs, hits on obscure words that you didn't even know were keywords, and the always uplifting hit from people who were looking for porn and were very, very disappointed to find your hub instead.
Give your weird search strings and a general overview of the actual topic of the hub that got the hit.
I've done a series of reviews on the preschool shows playing on the Sprout channel, which runs an evening show hosted by a young Latino lady whose character is named Nina. Needless to say, I've gotten hits from several variations on "nina naked" from no doubt very devoted fathers.
"dehydrated entrails" for a hub about arguing on the Internet.
"i want to use a cucumber on my wife video" for a hub about a chain e-mail about cucumbers.
I have a somewhat tongue in cheek hub on underarm whitening (it was news to me that women did this, I never give the colour of my armpits a second thought!) and it has been a bit of an education from the keywords that come up on my GA account as to what other parts of the body, internal as well as external, that people will whiten.
