My website www.mauitradewinds.com
appears to have had an abrupt decline in session duration around mid-April of last year.
From the launch of the site in 2014 until Apr. 2016, there were 34K sessions with an average duration of 2:30, and 4.3 page views, with a bounce rate of 29.3%. From Apr. 2016 to the present, there were 14K sessions with an average duration of 1:40, and 4.1 page views, with a bounce rate of 29.4%. The site has not change substantially. I am not sophisticated at interpreting Google Analytics data, but it seems that a sudden decline in session duration suggests that visitors are less interested. However, that doesn't seem to match the steadiness of page views per session, and relatively low bounce rate. I'm not interested in overhauling the website, but I'd appreciate some insight about how to interpret the data.
