My client wants to be able to know how many people come from Facebook to a particular page (promotion landing page) but then proceed to another page (promotion form thank you page). This second page isn't necessarily an exit page.
They'd also like to view this metric as a percentage of all traffic in that behaviour flow.
Currently I have it set up as a custom report with a pageviews metric with the following dimensions as a drilldown list: Landing Page, Second Page, Source, Referral Path. I also have two segments: Source contains "facebook" and Source does not contain "facebook".
I'm just wondering if there's a better way of doing it.
