The honest versions of first-impression claims, with their real citations.

Which statistics did not make this page?

Several figures you will find on nearly every other statistics roundup are absent here, because they do not survive a check at the source.

• "75% of consumers judge a company's credibility by its website design." The Stanford research says something more precise: 46.1% of credibility comments referenced design (statistic 29 above). The 75% version appears in no paper.
• "38% of people stop engaging if a layout is unattractive." Traces to a 2015 report whose primary source is no longer available. A decade old and unverifiable.
• "94% of first impressions are design-related." Comes from a 2004 study of fifteen participants evaluating health websites. Not a general statistic about the web.
• "53% of mobile users abandon a site that takes over three seconds." A 2016 figure whose original page has been withdrawn. Whatever is true in 2026, this number is not evidence of it.
• "Most UK web traffic is mobile." False for the UK specifically: see statistic 32. Global mobile-majority figures are routinely misapplied to the UK.

If you cite this page, you are welcome to link any statistic here; each carries its original source, and crediting the primary source alongside is always good practice.

Want your website on the right side of these numbers?

Most of the figures above describe gaps: sites that fail speed tests, checkouts that leak orders, businesses invisible to AI search. Closing those gaps is what we do. See how we approach web design and ecommerce, or get in touch for a straight answer about your own site.
