You can fix tagging errors using the Referrer page under Diagnostics in Performance AI. Here's how you can do it.
A. Navigate to: Performance AI ➡️ Diagnostics ➡️ Referrer.
B. This will open the Referrer page, where the tagging errors are listed. Every row shows
the no. of visits without source and medium that you can click to dig deeper:
a. The second column lists down the total no. of visits which in this case is 6144.
b. The fourth column lists down the visits with no source tag which in this case is 4621.
c. The sixth column lists down the visits with no medium tag which in this case is 6132.
d. You can generate a custom tag to fix the tagging errors associated with a referrer
domain.
e. Let's click the number in the second column (6144, to dig deeper), here each row lists
the timestamp, referrer URL, destination URL, and no. of visits. To fix the
tagging errors, visit the referral URL, and add UTM tags mentioning the source (in the
case of Google results, you might want to add it to blogs and other property website
mentions.)
