Attracting consumers to your site is only the first part of your problem. Once they show up, why do you think they’ll buy what you’re selling?
You’ve baited the hook and caught your audience’s attention, but if the bait’s not tied to anything your conversions sink straight to the bottom.
Behavioral psychology has a lot to say about why we buy the things we buy and what the decision-making process looks like.
Knowing what your customers want or need to see from you will help you convert the traffic you already have, and ensure that the ones who get away eventually come swimming back to you.
