According to this article, the page views and unique page views can be tracked in Google Analytics or in the report, but our figures do not match up. There's a difference by the thousands! Is anyone else having this problem?

Which did you find most reliable? We're trying to measure the impact of our Help Center and these measurements are key to our understanding.

Page views - This is the number of page views in your help center. You can track views in both Google Analytics and in the Knowledge Base reporting tab in Zendesk Support.
Unique page views - This is the number of unique visitors to your help center. Each visit to your help center counts as a session, and each session (usually), results in multiple page views. Tracking the number of users visiting your help center gives you some perspective about its use compared to the total number of views in a specified period. A monthly views total of 10,000 compared to 1000 unique users within that same period tells you that those users are viewing on average 10 pages per session. This helps you understand how many of your customers use your self-service content.
