Why can i not choose this placement URL?
When i enter this url - (gumtree.com.au/s-ad/yarra-ranges/cars-vans-utes/2010-toyota-hilux/1083141044) - as a managed placement, i get this error
"Placement URLs must be provided in a valid URL format."
This happens with every single URL on this site. Can someone please let me know why this is happening?
