If a Web page is irritating, consumers are quick to respond. Over 75% of respondents said they were "extremely" or "somewhat" likely to not visit an offending site again, and three-fourths of users expressed some degree of likelihood about unsubscribing from the offending company's promotional messages. Around 70% of users said they might refrain from making purchases at that Web site, view the company in a negative way or even refrain from making purchases in the company's offline stores. Interestingly, only 25% voiced any intention to complain to the company.
