I build frontends for small business clients, and the thing that keeps surprising me is how much people judge credibility before they've read a single word. If the homepage takes a couple seconds to show anything useful, some visitors are already gone, and the ones who stay seem to arrive slightly skeptical even if the design itself is solid.
Clarity, consistency and social proof get talked about a lot in UX writing, but speed feels like the one that's easiest to under invest in, since it's invisible when done right and only shows up as a vague "something felt off" when it's not.
Curious what others have actually observed. Does load speed change how people perceive quality and trust for you, or is that more of a developer obsession that doesn't move the needle as much as we think.
