Poor spelling can cut online sales in half. Yes, according to Charles Duncombe, the director of the Just Say Please group, which runs several websites, an analysis of website figures showed a single spelling mistake can cut online sales by half.
William Dutton, director of the Oxford Internet Institute at Oxford University, said there is greater tolerance towards spelling and grammar in some informal parts of the Internet, like forums (not mine of course) and other social networking sties. But for commercial sites, when a consumer might be wary of spam or phishing efforts, a misspelt word can be damaging to the credibility of the website.
