The generation gap exists in many shopping scenarios. This research explored the age gap in the perception of goods in search, experience, and credence goods, or the SEC framework, specifically for the online shopping environment. We found that age and Web shopping experience, and in some cases, their interaction, have significant influence on online shoppers’ perception of search, experience, and credence goods. Even controlling Web shopping experience, we found the effect of a generation gap on how consumers feel about product quality. Web shopping experience and senior age can reduce the uncertainty towards credence goods while the perception of search goods is only sensitive to age. We believe these findings will have important implications for future research on the SEC framework in the online environment.
