Recent reports have suggested that internet search behaviour may be a valuable tool to estimate melanoma incidence and mortality. Previous studies have used incorrect statistical methods, were focussed on the United States and/or did not use non-cancer control search terms to provide a context for interpreting the effects seen with the cancer-related terms. Using more robust statistical methods we found that no cancer search terms were significantly, or strongly correlated with melanoma incidence in 6 countries.
