Websites with technical difficulties do more than frustrate shoppers — they damage a brand’s reputation.

This was according to a new survey from QualiTest Group. The report, which was conducted with Google Consumer Surveys in June 2017, was based on a sample of more than 1,000 respondents from the United States between the ages of 18 and 54.

Despite large majorities of consumers shopping online (80% of respondents), 73% of consumers shopping with mobile Web, and 68% shopping with a mobile app said that user experiences (UX) haven’t matched widespread adoption.

Nearly 55% of consumers reported they experienced technical difficulties during the digital billing process. For 65% of shoppers, these glitches were either somewhat, or very likely to make them abandon a purchase — a factor that could lead to lower retailer profits and retailer struggles.
