This help page describes how ‘Pages not found’ works as a dimension. See the Pages not found metric for more information.
The ‘Pages not found’ dimension shows URLs that contained an error. This dimension is useful when you want to lower the number of errors that visitor get on your site.
This dimension retrieves data from the pageType
and g
query strings in image requests. If the pageType
query string equals errorPage
, the g
query string (page URL) is recorded. AppMeasurement collects this data using the pageType
variable. If the pageType
variable is not defined or set to anything other than errorPage
, no data for this dimension is collected.
Dimension items include the URLs of pages on your site where an error occurred.
