Campaign source not being tracked with custom parameters
I have auto tagging enabled and everything was working great. I could see the adwords campaign names in Google Analytics reports. This has worked beautifully last couple of years.
However I added a custom parameter in our destination URLs (http://www.ourwebsite.com/?c=xyz) and since this change the google analytics is not showing adwords campaign names anymore. More than 90% of the data is showing is "not set".
I have tried disabling Auto tagging and using analytics tracking urls but still no change.
Re: Campaign source not being tracked with custom parameters
The custom parameter should not conflict with Auto Tagging. The configuration of your Analytics Property may cause the difference.
