Analytics API returns wrong users count when fetching paginated result

问题

Trying to get data using GA API for java like it's described in the devguide.

Dimensions:

• ga:pagePath
• ga:date
• ga:country
• ga:hostname
• ga:userType

Metrics:

• ga:pageviews
• ga:sessions
• ga:users
• ga:uniquePageviews
• ga:bounceRate
• ga:pageValue
• ga:exitRate

I'm querying for a single date, max-result = 10000. There are more than 10k rows in result, so I'm querying in a loop using start-index.

The problem with that query is that in the resulting data number of users is ~3 times greater than number of sessions. When I'm making a simpler query (ga:users, ga:sessions broken by ga:date for the same date) the ration seems valid -- users/sessions = 0.8

Source code is available in a repository

Any ideas on how to get valid users count with that more complex query?

回答1:

Sessions (an odd metric in GA) are only counted on the first hit of the sessions i.e. the landing page. When viewing page-level data, if a page is not a landing page, do not be surprised to see 0 sessions with many pageviews or users.
