Custom Dimensions Not Showing in Google Analytics (Google Tag Manager Data Layer Implementation)
We are trying to pass our A/B test variations as Custom Dimensions. We are using Google Tag Manager. (Side Note - unfortunately I cannot insert screenshots to this post, as I keep getting an error message telling me it is invalid HTML, any idea how to tackle this?)
We are feeding the experimentID and experimentVariation into the data layer. These are then registered as Data Layer Variables in Google Tag Manager.
We have added the Custom Dimension to our main Universal Analytics Page View Tag.
Tag Assistant displays the correct information.
Just to confirm, the dimension has been set up in Google Analytics as well.
However, after 4 days, we have no data showing in the Custom Variables report in Google Analytics. Any idea if we've missed a step, or implemented something wrong?
