Banner blindness
People learn to ignore regions and shapes that historically carried advertising.
Users develop a learned filter for page areas and visual treatments associated with ads, and skip them even when the content there is useful. It is acquired rather than innate, so it tracks whatever conventions currently mark advertising. Anything that adopts the shape of an ad inherits the blindness.
How it shows up in software
In-product announcements, feature promos and upgrade prompts that look like ads get skipped alongside the ads. Right-hand columns, full-width coloured bars near the top and anything with a dismiss X all carry a learned skip. Interfaces that monetise with promotion are training this filter against their own messages.
Using it well
- Put important product messages in the content flow, styled like the rest of the interface, rather than in an ad-shaped slot.
- Trigger messages from what the person is doing so they arrive as relevance rather than as a broadcast.
- Keep promotional density low. The filter is learned from your own page, so every skippable banner teaches people to skip the next one.
- Check what people actually look at with eye tracking or first-click tests instead of assuming a visible banner was seen.
Where it turns manipulative
- Disguising an ad as native content to defeat the filter, which works once and costs trust when noticed.
- Styling a security warning or a billing failure like a marketing banner, so the message people most need gets filtered.
- Escalating to animation and interstitials to beat the blindness, which raises annoyance and hardens the filter.
Where you have seen it
Google Search
Ads sit in the result list with the same typography as organic results, marked by a small label, rather than in a distinct banner region.
Slack
Upgrade prompts appear inside the feature being limited, such as at the point where message history stops, rather than in a header bar.
Wikipedia
Fundraising banners sit at the top of the article body in page typography rather than as a graphic block.
What the research says
- Benway and Lane, 1998Mixed evidence
Participants searching for information on web pages missed large, colourful banners containing the answer, and succeeded when the same information was in plain page text.
Small sample on late 1990s page layouts. The direction has held up across later work, but the specific regions people ignore shift with design conventions.
- Dreze and Hussherr, 2003Mixed evidence
Eye tracking during browsing found participants largely avoided fixating banner regions, while still showing some memory effects from ads they did not look at directly.
Grades are a judgement about the evidence, not about how useful the idea is. Plenty of contested effects are still worth knowing, as long as you do not cite them as settled.
