I can't emphasize enough how much I try to tell my folks to figure out the right balance between running after metrics vs experience. It's actually not "versus" when we are speaking of these two things. Loved the example of "carb vs eating healthy" when discussing nutrition . Definitely a worth-checking-out post on this topic.
If you happen to pick the wrong thing to measure and try to move, you may end up doing something that’s actually harmful to people’s experiences. Observe following example:
“Originally, the click-through rate of this story was 2%. When we made this change, the click-through rate went up to 5% Hooray!”
What’s the problem? Click-through rate on a story does not tell us enough about whether the experience was actually better. What if I changed all the links on my site to “click here to earn $250 dollars”? Hell yeah, click-through rate would go up! But eventually, people will realize that I’m not actually giving them $250 dollars, and then they’ll get pissed. They’ll stop clicking on my links, uninstall my app, and give me a 1-star review in the app store while writing FUUUUUUU — in all caps.
