I understand the urge to try to maximize on stuff like this, but in the end it loses sight of what&#x27;s most important: the quality of the results. And sometimes I feel that a lot of valuable engineering time and effort is wasted on making things prettier and better monetizing in the short term when in the longer term the better search results are what would really move the needle.<p>And most A&#x2F;B testing focuses on the very short time effects of the change (and change all by itself, even change for the worse can have a short term positive effect just because something is new). On another note: A&#x2F;B testing has another limitation, which is that you&#x27;re optimizing for the bulk, please one person more and you more or less automatically annoy another.
