We have been getting a couple of queries about Conversion Tracking recently, some users have been seeing “webpage not known” listed in their Conversion reports where they would normally expect to see the URL of where the Conversion Tracking code had fired from.


Paul, from our Online Specialist Support Team would like to share with us the solution to this problem

and how it affects our advertisers.

The issue here can come from a number of different root causes but it essentially comes down to browser security limits, preventing access to top level URL information and so not allowing the Conversion Tracking code to fire the relevant page URL back to AdWords.


This is most often down to the use of iFrames. iFrames essentially provide access to another webpage whilst still technically being on the original page. eg. browsing on and completing a purchase via through an iFrame without ever leaving


There are other reasons for this such as the use of Virtual URLs or non standard implementation of Conversion Tracking code, but for the most part the issue has stemmed from the use of an iFrame.


As such we would not recommend the use of Conversion Tracking when using iFrames as you will potentially see data of this nature.
