Container audit
Every tag, trigger, and variable checked, with broken, duplicate, and unused items listed before anything changes.
The Problem
When Nobody Knows What Half the Tags in Your Container Do
Tag Manager makes adding a tag easy, so every agency and campaign adds one. Years later, nobody remembers what half of them do, and GA4 and Google Ads disagree.
01 · Duplicate tags
Two agencies' tags fire on the same form submit.
One conversion tag per action, with duplicates removed after testing.
02 · Fragile triggers
Triggers depend on button text that changes in redesigns.
Triggers listen for data layer events your developers push, not text on the page.
03 · Consent order
The Meta Pixel fires before visitors answer the banner.
Ad tags wait for the banner's consent signal before they fire.
04 · Risky publishing
Nobody publishes, because the last change broke tracking.
Every version is tested and named, so any earlier version can be restored.
Your container has 140 tags, and the newest one is called "Copy of GA4 event (2)". Three agencies worked in it, so one form fires two Google Ads conversions and none in GA4. Click triggers depend on button text that changed in the last redesign. The Meta Pixel loads before your consent banner gets an answer. Nobody wants to publish, because the last person who did broke sign-up tracking for a week.
We start with an audit of every tag, trigger, and variable, then delete what's dead and name what's left. Your developers get a data layer spec, so tags read stable values instead of button text. Ad tags wait for your consent banner's answer. Every change passes Preview mode, the platform's debug view, and a consent test before it goes live.
One clear naming system
Every tag, trigger, and variable follows one naming rule, so anyone can see what fires where.
A data layer spec
Developers push stable values like form name and order value, so redesigns stop breaking your tracking.
Consent wired in first
Your banner's choices reach Google, Meta, and LinkedIn tags before any of them send data.
Our Google Tag Manager Consultant Process
From Container Review to Trusted Conversions in Five Steps
You see the audit findings, the tracking plan, and the test results before anything is published. Every change sits in a named version that can be rolled back.
The first call is a free Google Tag Manager consultation. We read your container export, test key conversions in Preview mode, and list every broken, duplicate, and unused tag we find.
What's Included
What You Get With Our Google Tag Manager Setup Services
Each project leaves you with a container your team can read and conversions your ad platforms can use. Most projects include these six parts.
Compare Options
DeveloperLook vs Freelancer vs Ad Agency
A freelancer suits one quick tag, and your ad agency knows its own campaigns best. Here is how a Google Tag Manager consultancy compares when the whole container needs work.
| Feature | DeveloperLookBest fit | Freelancer | Ad agency |
|---|---|---|---|
| Starting point | Full container audit | The tag you ask for | Their own campaign tags |
| Data layer | Written spec for developers | Rarely in scope | Usually click triggers |
| Conversions | Every platform, counted once | One platform at a time | Their ad platform first |
| Consent | Consent Mode v2 tested | Only if you ask | Varies by agency |
| Testing | 3 checks before publishing | Preview mode only | Checked in their reports |
| Speed to start | Within a week of review | Often within days | Fast for their own tags |
| Ownership | Your account, your container | Your container, their notes | Often their account |
| Cost | Fixed price from $450 | Hourly, often lower | Bundled into ad retainers |

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built marketing websites and web apps for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Marketing Teams Trust Us With Their Tag Manager Container
Containers drift with every campaign. These habits keep yours readable, your consent handling honest, and your conversion numbers worth acting on.
Honest scoping first
If two broken triggers are the whole problem, we'll fix them and tell you before we quote. A rebuild waits until the audit shows you need one.
Tested before it's published
No version goes live without Preview mode, the platform's debug view, and a consent test. Your reports stay stable while we work.
Written down, not remembered
Every tag gets a name, a folder, and a note on why it exists. The next person in the container can follow it without calling us.
Consent handled with care
We wire tags to your consent banner and test both answers. We don't give legal advice, so your privacy counsel signs off on the banner itself.
Every change reversible
Changes ship as named versions with notes. If a campaign tag misbehaves, the previous version can be restored in minutes.
Your account, your container
The container, the GA4 property, and the ad accounts stay under your company's login. We work with the access you grant and hand it back.

Good fit
Marketing teams inheriting a container
Your new marketing lead found 140 tags from three past agencies and needs a Google Tag Manager expert to say which ones still matter.
Companies running Google and Meta ads
You spend on Google Ads and Meta, but each platform reports different conversions than GA4, and nobody can say which number is right.
Sites with visitors in Europe or the UK
Your site serves visitors in the EEA or the UK, and Consent Mode v2 and your banner must work before ad tags fire.
Product teams on React or Next.js
Your single-page app changes routes without full page loads, so page views and sign-up events are missed or counted twice.
Agencies managing client containers
Your agency runs tracking for several clients and wants to hire Google Tag Manager consultants who work quietly under your brand.
Not a fit
Shopify GA4 tracking only
You run a Shopify store and only need GA4 purchase tracking fixed. Our GA4 Setup and Audit Services page covers Shopify orders and reconciliation.
You need a server container
You want tags moved off the browser to a tagging server because of ad blockers and cookie limits. Our Server-Side Tracking Setup page covers that build.
Tracking inside your app
You need feature and retention events inside a SaaS product, not marketing tags. Our Product Analytics Implementation page covers Mixpanel and Amplitude setups.
Budget under $450
You need one tag added, and your budget is under $450. Google's Tag Manager help pages often cover it, and we'll tell you before we quote.

Google Tag Manager is free for most businesses, while Tag Manager 360, the enterprise edition, is sold through Google at custom prices. What you pay for is the setup. Our work starts at $450 for a container cleanup, $1,200 for a data layer and conversion setup, and $2,600 for governance across up to 3 sites.
A container cleanup takes 1 to 2 weeks, and a data layer and conversion setup takes 2 to 3 weeks. Multi-site governance takes 3 to 5 weeks. The slowest part is usually waiting for developers to add the data layer pushes, so we hand over the spec in the first week.
Yes. The standard version of Google Tag Manager costs nothing and covers what most companies need: tags, triggers, Preview mode, version history, and up to 3 workspaces at once. Tag Manager 360 adds more workspaces, approval workflows, and enterprise support, which matters mainly for large teams with many people publishing.
Create a container at tagmanager.google.com and add its two snippets: one high in the head, one right after the opening body tag. Then add a Google tag with your GA4 measurement ID, test it in Preview mode, and publish. On WordPress or Webflow, the snippets go in the site's custom code settings.
Add a Google tag with your GA4 measurement ID that fires on every page, after consent where your banner requires it. Remove any hard-coded GA4 snippet first, or page views double. Then add GA4 event tags for actions such as form submits, and check them in DebugView before publishing.
Pick the actions that matter, then fire a tag on each. The sturdy way is a data layer event your developers push, such as form_submit with the form's name, not a click trigger on button text. Create a Custom Event trigger, read values with Data Layer Variables, and send them in a GA4 event tag.
Create the conversion action in Google Ads, then add a Google Ads conversion tracking tag in Tag Manager with its conversion ID and label. Add a Conversion Linker tag on your landing pages, unless a Google tag already loads on every page. Turn on enhanced conversions for better matching, which sends hashed email or phone data from your form.
An account Administrator opens Admin, then User Management, adds the person's email, and picks their container permissions. Give agencies and freelancers Edit, so their changes wait for someone on your team to publish. Remove access when a project ends, and keep at least 2 Administrators from your own company.
Hire Google Tag Manager consultants when the container holds years of tags from several people, or when consent and ad conversions must line up. Your developer is the right person to push data layer events, and we write the spec they follow. For one simple tag, a good developer or freelancer is enough.
You do. The container, the GA4 property, and the ad accounts stay under your company's login, and we work with the access you grant. Every plan includes 30 to 60 days of support. After that, you can book a Google Tag Manager expert for new campaigns, quoted separately.
