The matter has not been resolved so far, to the best of my knowledge, so I am posting, hoping that the collective wisdom by now, may have found the explanation for this little mystery.
I wrote on sexting, mid-March, some 30 or so posts ago. Well, that post never made it anywhere close to the Top 10, Top 20 or Top Anything, for that matter.
Rather unexpectedly, the stats started showing a virtual upsurge of hits on that entry, yesterday afternoon (CET=GMT+1). During the night, that little posting topped all the others. All of the sudden, unexpected and very welcome traffic came from the Search Engines en masse for my little blogging experiment here.
OK, I went to all the major engines and their subdivisions (news, blogs, pix) and punched in the search term as in my stats. Link to my post (blog) is nowhere to be found. (My safe search is off.)
