I never quite know what I’m doing with my public Facebook page, but I can usually count on this much: Only a small fraction of however many people see something I post there will Like it.

Something different happened with the link I shared on Saturday to my USA Today recap of Mobile World Congress. Of the 516 people it reached, 320 have liked it. Which would be nice, except that so many of them appear to be fake accounts that I should have put scare quotes around “people” in the previous sentence.

My new fans all appear to be young women of excellent health and are almost all dressed for the beach, an evening out, or an evening in. Some of them apparently use the same first and last names to make it easier to remember them: Alyssa Alyssa, Isabel Isabel, Kate Kate.

So while my page does desperately need a better gender balance–Facebook’s analytics report its audience is 71% men, 29% women–I don’t think my page’s new pals reflect a genuine shift. Question is, what made this one post draw out the bots when others don’t? And can I at least get some of them to click on the USAT story itself and maybe linger over an ad or two?
