I came across a question on Yahoo Web Analytic Group regarding debugging tracking code on a webpage without having access to the Web Analytics tool. The answers to this question can be more than one but based on my experience, the best way to check Web Analytics code on a page is to use a Packet Sniffer.
Let us look at an example by going to www.msn.com and capturing the Omniture Web Analytics tag on their webpage using a tool called Fiddler. Please look at the 2 screenshots captured after the MSN-US page load was complete.
After double clicking on the Omniture code, you will have to click on the Web Forms tab on the top right in order to view the various parameters being passed onto Omniture. You will notice all the various parameters being sent to Omniture like the Page name, Language, Screen resolution and so on. This step will also tell us whether the custom variables we passed on the analytics code are being sent correctly or not.
Packet Sniffers have a very important role to play in Web Analytics as they can help fix issues like data not being present in the reports to discrepancy in numbers. Finally listed below are a few more HTTP Debugger tools that I’m aware of:
1) Adobe Experience Cloud Debugger
2) Charles Proxy
3) Debugger for Adobe Analytics
