Why do you skip right over the answer when it looks like an ad?
Your eyes have learned to jump over anything shaped like an ad - even when it holds what you need.
Banner blindness is the habit of ignoring page regions that look like ads: boxed, brightly colored, banner-shaped, or sitting where ads usually live. After years online, the brain treats that shape as noise and filters it out before you read it. The catch is that it skips the shape, not the content - so a real notice or a useful link gets ignored the moment it looks promotional.
You scan a website hunting for the support phone number, glide past a bright boxed banner three times, then realize the number was inside it the whole time.
We don't ignore ads, we ignore the look of ads - so put important info in plain text, not in a flashy box.
If your message, warning, or call to action is styled like an ad, people will scroll right past it - design it to look like content, not a promo.
Looks like a banner = brain says skip, even if it's the answer.
