Google is famous for making the tiniest changes to pixel locations based on the data it accrues through its tests. Google will always choose a spartan webpage that converts over a beautiful page that doesn't have the data to back it up.
You should always look for opportunities to test innovations on a subset of users if you can.
Never stop testing, and your advertising will never stop improving.
Growth hacking is the future of marketing. It has to be.
At any time of day, hundreds of different versions of Facebook are running on the Internet - with a changed color here, a moved button there - and the user response to each variation is measured. And the same is done with advertising.
Building the right product requires systematically and relentlessly testing that vision to discover which elements of it are brilliant, and which are crazy.
When you start using test audiences, it becomes more scientific than it is about the work itself, and that's boring.
You launch a site, and you see what works, and you continue to make it better.
Virality is not an accident. It is engineered. And that's why growth hackers beat traditional marketers.
Growth hacking isn't some proprietary technical process shrouded in secrecy. In fact, it has grown and developed in the course of very public conversations. There are no trade secrets to guard.
If you have a business website, make it stickier; redo the merchandising often and try new things until you hit the right homepage... then try and beat that. The most important audience drivers on the Internet are paid search and key word optimization. Concentrate on those. They are very inexpensive compared to banner advertising.
