So first I made test banners. Tested them on doubleclick studio & on the html5 validator, with no errors. All seemed great.
But in the next step… In DCM our trafficking department adds unique UTM links to each banner depending on the placement. The banners don’t recognize the utm link.
Unfortunately for me I made over 40 banners. I really don’t want to have to remake these in GWD.
Can I send one of my banners to see if maybe I did something wrong?
