What are the most effective growth hacking techniques you have personally tried and tested?

Obviously, they do the fundamentals well. Good brand. Good experience. Good word of mouth. Good PR. Etc. Etc. But after my interview with Ryan Graves, the head of Global Operations at Uber (https://www.growthhacker.tv/ryan-graves), it became clear that they are operationally advanced and this is a huge part of their success. I'll explain. Uber isn't just a single startup, it's essentially dozens of startups rolled into one because every time they enter a new city they have to establish themselves from essentially nothing (except whatever brand equity has reached the city ahead of them). This means finding/training drivers, marketing to consumers, and building out local staff to manage operations for that city. This is where Ryan Graves comes in. He has a protocol of everything that must be done, and in what order, and by who, to ensure the best chance of success in a new city. So how has Uber grown so fast? Essentially, they figured out how to grow in one locale and were relentless about refining their launch process to recreate that initial success over and over in new cities. No plan works for every city, and they've had to adapt in many situations, but it is still a driving factor for their success.

People hate calls. People hate emails. People hate mail. Do you really want your first impression to be that of an interloper and a pusher? Then again, most recipients aren't event going to look at what you send them. What is your niche? Office managers for private family healthcare providers in Peoria? Athletics department directors for NAIA schools? Sales managers at wholesale car dealers that make over $180 million per year in gross revenue? Know your niche and define your buyer (and it better be the CIO or VP). Is your buyer female or male? Older, middle age, or younger? What about her or his college education? What does he drive? Where does he live? Where does he eat his lunch and get his coffee in the morning? What does he read? Etc. Go to your buyer. Find congregations of your buyer. Professional associations. Conferences. Meet-ups. Trade shows. Offer to do free presentations--not on your product but on best practices or trends you observe in the industry. Make your presentation about solving problems your buyers deal with every day. Write blogs or columns for media they read. Again, focus on what they need/want to read. You will have a hard time keeping enough business cards in stock and click-throughs from your byline. This is a true "targeted outreach campaign." Don't waste your money and time with anything less than this. You're going to do great. Please let me know if you'd like to talk about it more!

For the sake of getting your question answered here it would help to simplify but that aside without firm stats on engagement and sharing it would be difficult to say however with the paid expansion of game like Flappy Bird, Angry Birds I would say viral apps come close to if not over a k-factor of 1.

There is quite a bit of information available online about eCommerce conversions rates. According to a ton of sources, average visitor-to-sale conversion rates vary from 1-3%. This does not mean the Furniture conversions will be the same. The bigger problem is that visitor-to-sale conversions are not a good data point to use to measure or tune your eCommerce business. All business have some unique friction factors that will affect your final conversion rate. It's very important to understand each of these factors and how to overcome them. The best way to measure and optimize is to take a conversion funnel approach. Once you have defined your funnel you can optimize each conversion rate to better the total effect. For example: Top of the funnel: - All web site visitors, 100,000 / month First conversion: View a product page, 50% of all visitors Second Conversion: Add to Cart, 10% of people who view products Final Conversion: Complete Checkout, 80% of people who put items in a cart In this example we see that only 10% of people who actually view products put them in to a cart, but 80% of those people purchase. If you can figure out why visitors are not adding items to their cart and fix the issue to increase the conversion rate, revenue should increase significantly because of the high checkout rate. You can use free tools like Google Analytics to give you a wealth of information about your site visitor and their behavior or there are some great paid tools as well.

I'm answering your question assuming that you hope to be able to replicate it's own success in your own mobile app. There are a couple of factors responsible for it's growth that are instructive to anyone building a mobile app. "Leveraging the intimacy and privacy of the mobile phone." We now have an *intimate* relationship with our phone like no other device in the history of technology. Every internet company that started before around 2010 has built their core interactions around "the old web" one which was accessed primarily via a browser on a computer. Companies that start with a clean slate, should be building their interactions around how to do whatever the app is supposed to do while leveraging what is unique to people's relationship to their mobile devices. Photo-sharing has become a core part of the way we communicate now. Snapchat built something that provided an experience that leveraged the feeling of privacy and intimacy that is unique to mobile. "Provided an escape from the "maturity" of other online services." Too many parents, aunts, uncles and other "old people" have encroached into the social networks of teens and young people. As a result, they've had a desire to find places to express themselves in places inaccessible by older generations. An important distinction is that it's not just parents and relatives that young people are trying to avoid, but also employers & colleges who are increasingly using "mature" social networks to review applicants. "Leveraged PR even bad PR" The fact that the app got so much press about it being used to sext was perfect PR for the company, as it essentially reinforced the brand experience that it has today. Essentially, "if it's safe enough to send a sext, it's safe for any kind of communication I want to have." And although the safety and security of Snapchat is actually not as advertised, it still enjoys the reputation of having less impact than any primarily web-based service. Building a successful mobile application is one of the hardest challenges to face designers, programmers and entrepreneurs in the history of writing software. Happy to talk to you if you're considering building a mobile app, about what I've learned about the "table stakes" for success.
