Banner blindness
also: ad blindness
Banner blindness is the learned tendency of web users to ignore anything that looks like an advertisement — banner-shaped blocks, bright boxed promos, content in typical ad positions — even when it contains information they are actively looking for.
The effect was named in a 1998 study by Benway and Lane, and Nielsen Norman Group eye-tracking research has repeatedly confirmed it since: gaze plots show fixations flowing around ad-shaped regions as if they were holes in the page. It is not a decision; it is a trained filter that fires before conscious reading.
The trap for your own pages: the filter keys on appearance, not ownership. A promo strip, a testimonial in a bright rounded box, or a CTA styled like a display ad can trigger the same skip — visitors ignore your content because it pattern-matches to advertising. Anything crucial that looks like an ad inherits an ad's attention.
In eye-tracking data, banner blindness shows up as cold zones over ad-like elements; a predicted attention heatmap surfaces the same risk pre-launch. When a Heatpoints scan shows near-zero heat on a banner you consider essential, that is the model echoing years of learned viewer behavior — restyle the element to look native to the page, then re-scan.
The practical rules: integrate important messages into the content flow, avoid classic ad dimensions and placements for first-party content, and never rely on the right rail for anything users must see.
