Primary Dimensions: Page vs Landing Page
I am confused as to why one would choose Landing Page versus Page as the Primary Dimension in the Dimension Drilldown. I have created a custom report. The Metric Group includes Page Views, Unique Pageviews, Avg. Time on Page and Bounce Rate. In Dimension Drilldown, I used Page>Social Network. I created a comparative custom report with the same Metric Group; however, this time I used Landing Page>Social Network. I thought Landing Page's numbers would be lower as this is the first page a person is visiting, the initial clickthrough. However, I was surprised to find that Page custom report was lower.
What is the difference between Landing Page and Page as far as being used as the Primary Dimension in reporting goes? Also, in what instances would/should you choose one over the other?
Thank you in advance for any feedback.
