问题
Currently using a custom dimension to pass the author name of each article viewed. The author name is appearing in GA but the only problem is that the number of pageviews are significantly reduced when we apply the custom dimension to a report.
For example:
/article/example : 1900 pageviews (without author name in the report)
/article/example "Bob Smith" : 800 pageviews (when using author name in the report)
Using GTM debug, we can see the custom dimension is being passed with the author name so i'm a little confused as to why the discrepancy in the figures.
回答1:
It is likely that author was not set or have different value in author. Are you trying same date ranges?
