I’ve never gone on a worldwide concert tour before (never say never, though!), therefore I’ve never had to promote a worldwide concert tour before. Selena Gomez, on the other hand, is quite well versed in that world. She clearly knows what she’s doing when it comes to promoting a show and selling some tickets, and the key to it is actually a lot simpler than you may have thought. It doesn’t require an in-depth advertising strategy or any sort of viral marketing campaign. All Selena and the rest of the Revival Tour people needed to do was get her in a silky little nighty and snap some pictures. Then, throw said pics up onto the Internet, and voila! Now that’s how you sell some tickets.
