I’ve found that some people are using a technique I haven’t seen before (which I’ve called “twitter traffic hijacking”) to divert traffic from a known source to their unknown low-traffic site: post a message with the Twitter @user of the known source and invite to follow you with an attractive message.
In this case, user @unlimitedideas is posting a message: “@OCCMundial Tenemos Vacantes, siguenos !!!” (We have job offers, follow us!!!), referencing us OCCMundial (@OCCMundial on Twitter), which is top-of-mind for jobseekers in Mexico, and hoping to appear next to us on Twitter searches. Then they publish messages with their own job offers.
It’s certainly ingenious and shows off the way SM is changing the game.
