It started when we went on a family vacation to Seattle a few weeks ago. My two teenagers—who typically just grunt at each other in passing—were engaged in conversation and chatter in the backseat of the rental car.

We then began our sightseeing jaunts around the city and they talked, walked and seem utterly engaged. It turns out they were playing the latest Internet social phenomenon—Pokémon Go— an augmented reality game in which you hunt virtual Pokémon on your phone in real-life locations.

As we walked the streets of Seattle, my teens ran into others playing the same game. They talked to strangers about their latest catches, and I'd hear them say "Dude … what team are you on?" This game brought about common bonding among complete strangers.

Pokémon Go is so big, actually, that it's already catching up with some of the largest social networks out there. There is little doubt by now that Pokémon Go is becoming the most successful mobile app of all time, at least as far as launch-week performance is concerned. It took only 13 hours to hit the top of the U.S. sales charts in its first week. And it hit a 10.81-percent daily user penetration level only four days after its U.S. debut. And did I mention that Nintendo's valuation increased an estimated $7.5 billion thanks to this game?

It's a marketer's dream! In fact, Forbes contributor and blogger Jayson DeMers shares these marketing principles we can take from this global phenomenon.

1. Good branding can sell just about anything. Pokémon Go is actually loosely based on a system that already existed for another location-based mobile game, Ingress. Have you ever heard of Ingress? Possibly, but it didn't achieve breakout success because its brand never became well-recognized. Pokémon, on the other hand, is a brand that's been consistently developing itself for more than 20 years. Its character design, game quality and tone as a video game series (and anime) has become so powerful, that its presence alone helped sell the game to multiple generations of Pokémon fans. The game itself is good, but without the branding, it never would have taken off.

2. Timing is really important. Pokémon launched just after the start of summer, when kids are out of school, festivals are kicking up, and people are looking for any excuse to go outside and walk around. Can you imagine what it would be like if the game launched in the dead of winter? During a blizzard? The launch date is no coincidence. It's also good timing in a broader perspective; Pokémon is 20 years old now, and fans who were children when the series first launched are now 20-something adults with significant buying power.

3. Social proof is everything these days. Thanks to our immediately connected, highly communicative, social media-integrated world, social proof is everything in the modern era. We won't buy a product unless someone else has reviewed it first. We won't notice a business unless we hear someone else talking about it. With Pokémon Go, social proof is visible—when you see people having fun with the same mobile game almost everywhere you turn, it's almost impossible not to want to get involved.

4. A sense of identity leads to loyalty. There are a handful of identity factors that make Pokémon Go such an addictive hit, all of which give users a sense of belonging and loyalty. The first is a layer of nostalgia; 20-somethings all over the country grew up with Pokémon, and this is a way for them to hearken back to the original feelings they had playing the game in the late 1990s. The second is a division of loyalty; in the game, you must choose between three rival teams, and being able to identify with one gets people more invested, similar to the way sports fans become so invested in their teams.

Whether you are looking to launch a new product or rebrand an existing one, take these lessons to heart.
