I'm talking about Path Length Pages Per Visit when pulled with Ad Hoc Analysis not just through Reports and AnalyticsGigazelle, thanks.  I think your answer is what I was looking for.  Can you elaborate a little on what custom-link only visits are or maybe provide an example?  Sorry, I'm new to this...

Hi.  When I run a path length analysis in Ad Hoc tool I have a significant number of Pages Per Visit: 0.  I'm not sure how to interpret this.  When I run a similar report in Report and Analytics, the Pages Per Visit: 0 category is not shown
