Getting Started With Google Tag Manager V2

| 4 minutes to read

Google Tag Manager first launched in 2012, although despite its powerful features, it’s still not widely utilised by websites. The second version of the interface, known as Google Tag Manager V2, or GTM V2, provides a more intuitive and easy-to-use tool whilst still providing the same powerful features. Here’s what you need to know to get started with GTM V2.

What is Google Tag Manager?

GTM is a powerful tool that gives marketers and webmasters more control and flexibility over a website’s code and tracking. It enables marketers without development experience to implement important functions or features such as event tracking, Schema and much more from within a simple, smart interface.

You can read more about the tool on the GTM FAQs page or check out Google’s introduction to the tool in this short video:

So, what’s new?

For anyone who already used or has used the original GTM, Version 2 is visually very different so it can take a minute to get used to.

The look and feel is now much closer to that of other Google properties, such as Analytics and Webmaster Tools, which makes it somewhat easier to navigate once you adjust to the new layout:

Google Tag Manager V2 Interface

One change to be aware of is the renaming of Rules and Macros, which are now Triggers and Variables respectively. These work in very much the same way, but the names now make a little more sense. Setting these up though, like tags, is definitely a little different.

Version control is very much the same, but like the rest of the interface it’s set up a little differently:

Google Tag Manager Version Control

If you’ve used the first GTM, I recommend browsing around the various tabs and navigation menus to familiarise yourself with what’s new and where to find everything. You should find it much clearer and more intuitive, so getting to grips with the new style shouldn’t be like learning to use a completely new tool.

Migrating to Version 2

If you have not already migrated your V1 GTM accounts into V2 manually, they will have been automatically transferred on 1st June 2015. As such, there is no action you need to take in order to migrate or upgrade your accounts, but it’s definitely worth testing everything thoroughly to ensure your information was transferred in the way you’d expect.

Use the Preview and Debug feature to run tests and make sure your tags are firing as they should:

Installing GTM

Setting up GTM on your site if you haven’t used the previous version is a straight forward process with prompts that guide you through the process. In short, you simply need to create an account and install the container code on your site.

Creating A GTM Account

The GTM container code is provided after you enter some basic details (above) for your account and should be added immediately after the openingtag on every page of your site.

GTM Tags

GTM is all about tags. Tags are the individual pieces of codes that are fired via the container you install when certain criteria, or Rules, are met.

There are many different types of tags, including both pre-set and custom tag options. Here is an example of just a few different tags you might need:

GTM Useful Tags

Setting Up A Google Analytics Tracking Tag

There are two main types of Google Analytics tag: Classic Google Analytics and Universal Analytics.

If you haven’t moved over to Universal Analytics yet, a move to GTM would be a good time to do so, as long as you test everything thoroughly at every step. Classic Google Analytics is being phased out and so the sooner you have accurate data tracking using Universal Analytics, the less work you’ll leave yourself in the future.

The main Google Analytics tag you’ll want to set up, even if you use no other tags at all, is a standard Page View tag to fire on all pages. This means that whenever a visitor views any of your pages, the Analytics tracking code fires and data about their visit is sent through to the Google Analytics interface:

GTM Google Analytics Tag

To create this tag, simply choose “Google Analytics” as the Product in the first section and choose either Universal Analytics or Classic Google Analytics as required in the second step.

Section 3 then asks you for your Tracking ID, which you can either enter manually (it’s your Google ID beginning with “UA-“) or you can create a Variable for your tracking ID so you only have to enter it once. For more information on setting up your Tracking ID variable, please download our free GTM whitepaper.

You can either use the little brick icon to browse for your Custom Variable or you can enter it in manually, in the format of {{trackingid}} – where “trackingid” is the name of the Tracking ID variable you created.

The last step is to tell Google when to fire the tag, which for your Google Analytics main tracking code tag will be on All Pages. Once you select the All Pages default Trigger, you can hit save and you’re done!

Managing Director

Sophie Roberts is Managing Director and owner of Koozai, one of the UK’s longest-established digital marketing agencies. Having joined the business in 2016, she became Managing Director in February 2018 before leading a successful management buyout in 2021.

With more than 30 years of marketing experience, Sophie specialises in AI Search, Digital PR, marketing strategy, agency leadership and helping businesses adapt to the changing search landscape. She works closely with clients and Koozai’s specialist teams to develop commercially focused digital strategies that improve visibility, strengthen brand authority and deliver measurable business growth.

Over the course of her career, Sophie has worked with more than 200 organisations, ranging from ambitious SMEs to household brands including Golden Wonder, Airfix & Humbrol and Victorinox Swiss Army Knives. Since joining Koozai she has helped shape digital strategies for clients including Travelbag, Trevor Sorbie, Red Funnel and Côte Brasserie, building long-term partnerships that often span many years.

Although clients often approach Koozai for Technical SEO, PPC, Digital PR or AI Search support, Sophie’s approach has always been to understand the wider business challenge rather than simply deliver a marketing service. She believes the best client relationships come from treating every client’s business as if it were your own, combining commercial thinking with honest advice and a genuine investment in long-term success.

Sophie’s career began in public relations, where she led award-winning campaigns before moving into digital marketing. One of her earliest successes was the BBC’s Service! campaign, which won the Catey Award for Best Independent Marketing Campaign and helped raise the profile of front-of-house hospitality careers across the UK.

Since then, she has developed marketing strategies for organisations across hospitality, construction, travel, tourism, healthcare, education, retail, ecommerce, finance, automotive and manufacturing, giving her broad commercial experience across both B2B and B2C sectors.

More recently, Sophie has become one of Koozai’s leading voices on AI Search and the impact of generative AI on marketing. She has developed the agency’s AI prompt library, built custom GPTs and AI agents to improve internal efficiency, and created Koozai’s AI usage policy to help the business adopt AI responsibly and effectively. She is particularly interested in how AI is changing the way people discover brands, products and services, and what businesses need to do to remain visible as search continues to change.

Sophie regularly writes about AI Search, Digital PR, organic growth, marketing strategy, leadership and the practical application of AI in marketing. She also reviews and fact-checks Koozai’s AI Search and digital strategy content before publication, ensuring it is accurate, practical and reflects current best practice.

Alongside her agency work, Sophie has delivered webinars on SEO for the construction industry, spoken at digital marketing events across Hampshire, featured in Search With Sean Live and supported the hospitality industry through judging and organising prestigious awards, including the UK Sommelier of the Year and UK Restaurant Manager of the Year. She also served on the organising committee for the National Restaurateurs Dinner.

Her work has been recognised through both personal and agency awards, including the Catey Award for Best Independent Marketing Campaign and the Construction Marketing Award for Best Small Agency.

Sophie holds a BA (Hons) in Marketing & PR together with Google and HubSpot marketing certifications. She continues to explore how emerging technologies can improve marketing effectiveness while keeping people, creativity and commercial thinking at the heart of every strategy.

Her insights and commentary have been featured by publications including Moz, Sitebulb, Yahoo News, The Business Magazine, Hampshire Business News, Portsmouth News, The Daily Echo, Professional Electrician, The Caterer, Restaurant Online, HVP Magazine and many other industry publications.

Away from work, Sophie is a self-confessed foodie, proud geek and lifelong learner who believes every day should be a school day. She is passionate about creating positive workplace cultures, supporting work-life balance and helping people build careers they genuinely enjoy.
