The aim of this brief communication is to develop a tracking methodology to analyse the effectiveness of inlink visits (return visit behaviour and length of sessions). In other words, how deep do inlink visitors navigate into the website? Do all inlinks perform the same? This paper addresses these questions by time series analysis of Google Analytics data, with a methodology developed by Plaza (2009). The importance of this article is not the particular website but the methodology tested to arrive at these results, an experiment that could be repeated with different websites.
