I was wondering if it is possible to either create a smartlist or have the list of contacts that came to my website through a Google Ads campaign or a facebook campaign for example ? Seeing as there are Marketo tag on the website, does it provide us with the source of trafic from where the contact came from on our website ?
Have you searched the Community for "traffic source" and read all the results? You can also search "UTM" and dive in. That's going to be a lot more useful than a brief summary. Let us know after you've consulted those past threads.
