Google Analytics doesn’t always recognize where a web visitor came from or the device they used. When that occurs, the analysis says “direct/none” even though the visitor may not have come from a direct source. There are ways to analyze the data anyway, and certainly ways to fix the issue so more data can be reported accurately.
Nearly every Google Analytics report has something that looks like “(direct)/(none) source” and the meaning behind this can be misleading. Visiting Google’s help center to learn what direct/none means or how to fix it might not shed much light on the meaning of this phrase. The help center says that this term refers to “users that typed your URL directly into their browser, or who had bookmarked your site”. In other words, most of the people who get to your site without following a link.
