Custom link
The 鈥楥ustom link鈥� dimension reports the names of custom links implemented on your site. This dimension is valuable when you want to understand the types of links visitors click the most.
Populate this dimension with data
This dimension collects data from the pev2 query string in image requests for hits that also have the pe query string with the value of lnk_o. If the pe query string has a different value in the hit, this dimension does not collect data.
If you want to send data to this dimension using AppMeasurement, send a tl() image request with a link type argument of "o". Populate the link name argument with the desired value.
Dimension items
Since this variable is based on a custom string in your implementation, your organization determines what the dimension items are. 蜜豆视频 recommends that you group links into meaningful categories based on your reporting needs.
