Dear Erik,
Entry Page / Entry URL is the first page of visit and all the metrics in the visits are attributed to the dimension.
Whereas Entries is a metric associated only with the first page of entry.
Example : Assume the below flow.
A >> B >> C >> D
Total Number of Page Views is : 4
Dimension by Page : A = 1, B = 1, C = 1, D = 1
Dimension by Entry Page : A = 4. This is because, Entry Page A contributes succeeding Page Views. B, C and D are not Entry Pages.
Total Number of Entries is : 1
Dimension by Page : A = 1
Dimension by Entry Page : A = 1
So if you take Entries as metrics, both Pages and Entry Page should have same numbers.
Thank You
Arun
