Google Analytics is, at its core, a simple and powerful tool. But once you start to customize the code to take advantage of all the flexibility available you may find yourself needing some help troubleshooting a nagging issue.
A new Chrome Extension created by engineers here at Google hopes to make troubleshooting tag installs much easier. Tag Assistant aims to highlight errors, warnings, and provide useful suggestions for Google's most widely adopted tags including Google Analytics, Google Tag Manager, Adwords Conversion Tracking, the new Remarketing Tag, Trusted Stores and Floodlight.
After installing the extension, Tag Assistant will alert you if tags are found on any page you are currently browsing. For each tag we will tell you if it appears to be working or if we notice any problems with your implementation. Tag Assistant will even make recommendations on how to improve your installation if we notice any optimizations. For example, if you have 2 or more tags implemented separately we might suggest that you migrate to use Google Tag Manager instead.
How does it work? Tag Assistant looks for errors in two different ways. First, we check the source code to look for common errors like forgetting to include a closing </script> tag. We also review the HTTP headers to ensure that we are getting expected responses.
Since launching in October of 2012 we have collected a lot of your feedback and have added dozens of new checks. Over the course of the year we will be adding more checks that will make the Tag Assistant more accurate and helpful.
We encourage you to try it out for yourself by installing it via the Chrome Web Store. If you have feedback on new checks to add or if you have questions about the tool, join our Google+ community where our team and users can help you out.
