Google Tag Manager
Google announced this afternoon on the Google Analytics blog that it will be entering the tag management (or tag container) world with its own free Google Tag Manager product.

With the ubiquity of web analytics, conversion tracking, ad measurement and remarketing platforms today, websites can feature a multitude of different ‘tags’. Tags are essentially small pieces of script that are implemented on web pages to allow data to be collected or to target advertising to relevant users.
As useful as these tags can be (without them, Google Analytics for example would not collect and report any data about your website), they can also be quite problematic. Reliance on IT support (often third party) to make onsite code changes for new or updated tags can slow the process of making new, reliable data available. Furthermore too many tags can slow page load times and cause JavaScript errors on pages.
Essentially the old way of manually changing all tags on a site through the code reduces reliability, increases the time and effort involved and keeps control of marketing and measurement tags away from marketers. A tag container is a tool that allows you to all website tags within a single line of code. This single line references an external JavaScript file, which allows you to manage all tags from within a single web interface. New tags can be added and existing tags can be updated or removed without requiring direct access to the website files and without needing to go through IT (resulting in a win-win situation for all involved).
Google Tag Manager is a completely standalone product (i.e. not a Google Analytics specific product) and supports both Google and non-Google tags. Default versions of certain tags are included for ease of use but full customisation of tags is also possible. Some of the key benefits of Google Tag Manager (paraphrased from the official GA blog post) include:
- Asynchronous tag loading. This means that each tag fires independently of each other and from the main page load, increasing accuracy and helping to keep page loads within acceptable times
- As mentioned above there are tag templates provided, so marketers can quickly add standard tags with ease, but also support for adding custom tags
- A native error-prevention tool (Preview mode) to view changes before implementing them, the Debug Console, and Version History to ensure that new tags won’t break your site
- User permissions and multi-account functionality to make it easy for large teams, agencies and clients to work together with appropriate levels of access
The product roadmap will also ensure that new features are added to the tool over the next few months at least.
The process of setting up Google Tag Manager is as quick and easy as any other Google product. Once an account is created, one snippet of code needs to be added to your site. After that you can start managing your tags through the interface.
Of course it is worth noting that larger, more complicated sites will require thorough planning, migration and QA to ensure the migration process does not impact on data collection. As a Google Analytics Certified Partner, Fresh Egg is already testing Google Tag Manager and we are very excited about rolling this out across client accounts – and reviewing the product more comprehensively – in due course.

Hi Dara,
Have you actually had any success using GTM with BingAds conversion code?
We’ve tried but haven’t got it to work and have read on the GTM product forum that the code needs modifying but the guy isn’t letting on his trick. Any ideas welcome, I have been scouring blogs for examples of someone who has done it but I’m yet to find one.
Cheers
James
Hi James,
Thank you for your comment and apologies for the delayed response – Dara is out of the office at the moment, but he’s kindly sent a response, which I’m posting on his behalf:
So far none of our clients using the GTM are using Bing advertising so we have not needed to tackle that issue yet.
I am aware that some people are reporting the same problem in the Google product forums and one person has suggested a solution in this thread (http://productforums.google.com/forum/#!msg/tag-manager/rZroFUmGTGQ/whRsIAxfj2AJ) since you commented on our post.
Please do let us know if you can make it work by simply removing the first part of the Bing tracking code as suggested in that post. I am sure you will not be the last person to be searching the web for an answer to that question!
Hi Laura / Dara,
Thanks a lot for the reply. We have been following that thread as well and have now successfully registered conversions by removing the part of the code mentioned. However this seems to have stopped the functionality of being able to pull revenue in, which is frustrating.
We’ll let you know if we get anywhere with it.
Cheers
James
I tried the google tag manager but it gave all kinds of errors on my site.
there is a script referrer to http://www.googletagmanager.com/gtm.js and this file gives a nice 404 error.
So…. Tag Manager isn’t gonna work I guess.
Hi Theo,
Hitting http://www.googletagmanager.com/gtm.js will lead to an error page as this is missing your GTM container ID. If you try http://www.googletagmanager.com/gtm.js?id=GTM-XXXX where XXXX is replaced with your container ID then this will show you the JavaScript.
We are using GTM successfully on many sites so I would suggest you double-check your implementation if you are seeing errors and refer to the official help site http://support.google.com/tagmanager and the GTM developers guide https://developers.google.com/tag-manager/devguide.
Cheers,
Dara
