Have you had a conversion from your PPC traffic yet? It isn’t going to show “Verified” until well after you have had at least one conversion that came to your landing page from your PPC ad.
You can check that conversion tracking is installed and working by clicking one of your own PPC ads and complete the purchase, lead, or whatever task you have designated for conversion. When you get to the Thank You page where you placed the code snippet, you can view the source to see if it appears correctly within the HTML code. Within 24 hours of completing the transaction, you should see the conversion appear in your stats and the status will update to “Verified” if all is working.
