I am trying to do a remarketing in Adwords. I create my custom audience list from Google Analytics and export it into my Adwords. Now, the new imported marketing list is shown "unavailable" and Adwords shown "We haven't detected the AdWords tag on your website or in your app".
Is it caused by not adding AdWords remarketing tag to my site?
Any ideas? How can I solve the problem?
