A client is managed GDN by our agency, but GoogleCPC is managed by another agency.
Recently we can't count on-click conversion& view through CV.
Perhaps two on click conversion tag can't measure in the same page?
(of course conversion ID is different )
I don't know of any reason why two conversion tags from separate AdWords accounts couldn't fire on the same page.
I think it's more likely that some other script on the page is preventing the tags from firing, or the implementation of the tags has been corrupted and the code isn't set up properly.
Check the Conversion page under the Tools menu in AdWords to see what Tracking status the conversion action has. If it says "Tag inactive," or if it says "No recent conversions" and the system hasn't seen the tag on your website for a number of days, you probably have an issue with the implementation of the code.
I hope that helps!
I woder why tags can't fire on the same page.
I can check with YTM, there is no problem for implenmetation of the code.
However, Adwords account, I can see "No recent conversions".
