Growth Hacking is a very wide field and is basically about finding experimental and measurable ways of increasing growth. You can increase inflow of new visitors by improving marketing, PR, paid traffic and virality. You can increase the likelihood that these visitors become engaged long-term users by Conversion Rate Optimization and by improving Activation and Engagement. And you can make more money by tweaking your business model by experimenting with different models for how to make revenue.

Across it all there is the question of leveraging a lot of fantastic tools and insights that are out there and focusing on and measuring the right metrics as you go along. Below, we have collected references to a set of resources that we have found very useful, grouped by what aspect of Growth Hacking that you want to dig deeper into.

Just starting on CRO? – nail the lingo, tools and best practices fast here

There is a wealth of resources out there that help you optimize conversion in your funnel.

Activation and Engagement

Activation and engagement may be the most important yet fuzziest discipline of them all. Here are our recommendations for specific and actionable reading.

Whether you call it engagement or activation, it’s all about maximizing the value that users experience using your service. It’s a lot about understanding what the users should do early on to become “activated” and about knowing that IF your users do this and have that experience, they will show long-term engagement and be more likely to have a long life-time and hopefully also be payers.

3 Growth Hacks Secrets for Massive User Growth

In this video, Josh Elman who used to be growth lead for Facebook, LinkedIn and Twitter talks about the tools these companies used to drive massive growth to their sites. The video offers a good and informative insight in to what the biggest players in the field are doing to grow their businesses.

Growth hacking: leading indicators of engaged users

The reason you want to increase activation and engagement is that you want to improve your business. A first key activity, then, is to find out what kind of engagement that truly drives your business. A lot of the key players and world-class growth companies have found just that: The engagement metric that truly drives the business. Read here about Facebooks Seven Friends and what Dropbox, Twitter and LinkedIn have found drives their growth.

Startup Metrics for Pirates: AARRR!!!

Dave McClure has a wonderful framework for discussing the various phases in the funnel and the metrics that matter for the growth of a startup business. We have benefited a lot from the idea of Activation – it does not end when users come to your site or sign up. You really need to give them a good experience – to activate them – before you can hope to sell to them, make them viral and make them come back again and again.

Does SimpleSite have a “7 Friends in 10 days” like Facebook?

We have found our engagement metric in SimpleSite. Unlike in many other services, it’s not in the form of a threshold (7 friends in 10 days), but rather a sum of the number of interesting actions taken in the first three days. Read more about the data and analysis that led us to this conclusion.

CRO and Engagement Optimization together are what maximizes the business value of the traffic that you have. You ARE spending resources on getting traffic (be it Paid Search, intensive SEM, active PR, viral product development, …) and getting CRO and engagement right ensures a high ROI on those traffic-generating efforts and expenditures. And that in turn makes your traffic generating efforts viable and allows you to scale on a Growth Engine that works.

A/B experiments

This is easy in principle – just split and test. But be sure you know how to get significant results. Read here how.

A/B experiments are a powerful tool in learning what works. You can split the user experience in two (or more) and see how the users exposed to the two variants react to them. That may be in the form of better conversion, more engagement or any other metric that you know drives your business.

Be very aware, though, that you need enough volume to get statistical significance.

Our 10-1000 rule of thumb is: “It takes a thousand events to measure 10%”. Basically, if you want to measure a 10% improvement in the number of sign-ups you get on the B-track in an experiment, you need about a thousand sign-ups on both tracks. So if you have 10 sign-ups a month, don’t even bother to A/B test if you are looking for 10% effects. If you have a total of 10.000 sign-ups a day, you can find a 10% increase in a few hours. If you want to find a 10% increase in something far down the funnel, like sales, you need a thousand sales on each track, something that can take a fairly long time, if you are not routinely making thousands of sales per week or month.

In conclusion: How long you have to measure or whether it makes sense to do A/B experiments at all depends on the volume of the outcome you are trying to measure. And when it does make sense, A/B experiments can teach you a lot about improvement.

A/B testing – a comprehensive guide to getting started

An in-depth guide that comprehensively covers all the basics. The whys and the hows, the organizational challenges and the wins to look for.

A/B Test (Split Test) Calculator

It is really – as in REALLY – important that you understand the meaning of significance. It is very easy to hack some A/B test together, run it for a while and then conclude some 10% improvement. However, unless there is enough data, that result may be totally random and unfounded and may lead you to make uninformed and even wrong decisions. So use a tool that shows you the significance or be able to calculate it yourself. The significance calculator linked here does the calculation for you and even sheds some light on the underlying math. You may also want to internalize our 10-1000 rule above. It is a great help in making qualitative assessments as to whether an experiment makes sense doing or has a significant result.

Metrics and analytics

Move from vanity metrics to metrics that actually drive improvements in your business

Metrics are key to understanding what you are doing and whether you are improving stuff or just standing still. It is vital to discern between vanity metrics and real metrics. Vanity metrics are fine on slides and typically look very impressive. Real metrics tell you if you are improving and growing your business. There is a lot of best-practice on which real metrics to measure, for which types of services and at which time in the life of a business.
