Emotional Intelligence

“Number one is Emotional Intelligence, and people talk about the concept of emotional intelligence, but there's actual research and psychology around that. I believe it was published in the '80s, but there's a really good book that summarizes the foundational research around emotional intelligence. And it's very useful when building relationships and communicating with people to understand their emotions. So that's the first one. And doing growth because growth is getting people to use your stuff. And so if you have frameworks to inform how people will use your things, then you can be a more effective growth person. Which brings me to my second book, which is Cialdini's Persuasion book. Robert Cialdini does a bunch of books around persuasion, but again, there's frameworks for how to persuade somebody to sign up, buy something. And so he breaks down his framework for that, and again, it's based on psychology. And I think especially in growth, there's all kinds of psychology research and behavioral economics research to inform tests. And if you just read Thinking, Fast and Slow, Persuasion, Emotional Intelligence, you can basically take those frameworks and apply it to growth in all kinds of different ways. And then the last is How to Measure Anything. So How to Measure Anything is about measuring things that are not immediately obvious to measure. They give this example of they wanted to measure how good an orchestra conductor was and they could survey or they could see the number of standing ovations for each orchestra conductor. And the more standing ovations probably means it's this better one and that you don't need to survey people. But much of growth and business is things that are not immediately obvious for how to measure, but anything could be measured, and so that's my third record.”

And your non-SEO traffic is actually an authority signal. So I'll go into Similarweb, I'll put the domain in, I'll look at the total traffic, and I'll want to see at least, I would say, 1000 visits a day roughly for non-SEO, at least.
