AuthorIf you feel like your reports are missing data, conversions don't add up, or ads aren't performing as expected, your tracking might not be working properly.
This often means the setup isn't correct. Tags may be missing, placed in the wrong spot, or not connected to tools like Google Analytics or Meta.
A GTM expert helps fix this by organizing your tags, linking your tools, and making sure every action on your site is tracked the right way.
In this guide, we'll explain who they are, what they do, and how to choose the right one for your setup.
A tracking specialist sets up and manages the tools that collect marketing data on your website or app.
This includes everything from GA4 and Meta Pixel to LinkedIn Insight Tag or TikTok Ads.
Their job is to make sure actions like button clicks, purchases, or form submissions are tracked correctly and show up in your reports.
They usually work with a tag manager like GTM to install tracking tags without needing help from a developer each time.
Tracking specialists define when tags should fire. For example, only after someone reaches a "thank you for the order" page.
In small teams, this role is sometimes handled by a marketer or analyst.
But with modern tools and privacy rules getting more complex, many companies now bring in a dedicated expert or agency for help.
Services like Stape Care offer on-demand support with setting up, fixing, or upgrading your tracking so you don't waste ad budget on missing or broken data.
Stape Care can also help you run a full audit using tools like the Stape Website Tracking Checker to spot broken tags, verify data flows, and identify tracking gaps.
A GTM expert is a tracking specialist focused entirely on Google Tag Manager.
They know how to set up, organize, and manage all your marketing and analytics tags inside GTM.
They work with containers, triggers, variables, and the dataLayer to control when and how tags fire.
Once GTM is installed on your site, GTM experts use its functionality to add or adjust tracking, from GA4 events to Meta Pixel or LinkedIn tags.
And all of that without needing a developer. For example, if you want to track a button click or PDF download, a GTM expert can configure that in minutes without touching your website code.
Most GTM experts also have basic web development knowledge, which helps them write custom scripts or troubleshoot when something isn't working. They also test setups in GTM's preview mode and use browser tools to check if tags and variables behave as expected.
Many GTM experts today work with server-side tagging using server GTM.
This setup sends data through a cloud server, helping reduce data loss and improve privacy.
The Stape Care team has deep experience with this and can help businesses upgrade to a server-side model when ready.
A GTM expert is responsible for making sure all tags on your website fire correctly, at the right time, and send the right data to the right tools.
Here's what they usually handle:
A GTM expert adds and configures tags inside GTM: from GA4 and Google Ads to Meta Pixel, TikTok, LinkedIn, Hotjar, and more.
They make sure each tag has the right settings and tracking IDs, and use GTM's functionality to manage everything in one place.
Triggers define when a tag should fire. For example, only after a form is submitted or a user scrolls halfway down the page.
Variables let GTM grab the right data, like the total order value, product name, or page URL.
A GTM expert sets these up to capture exactly what matters to your business.
Most GTM experts also handle analytics configurations.
They set up GA4 event tracking, make sure Meta Ads receive conversions, and connect your tracking to other tools like Klaviyo or Mixpanel.
This helps keep all your platforms in sync and gives you consistent data.
Sometimes, tracking needs to go beyond templates.
A GTM expert can write small JavaScript functions inside GTM to capture dynamic values or clean up the data before sending it out.
For example, they might track which video someone watched by detecting the video ID when a user clicks play.
Or they might combine a customer's first and last name into one value before sending it to your CRM tool.
GTM experts use these scripts to make sure your tags get the right details, even when the default options aren't enough.
When data looks wrong, or a tag doesn't fire, the expert checks what is wrong.
They use GTM preview mode and browser tools to debug what happened and fix the setup.
GTM experts also test again after changes to make sure everything works.
Old or unused tags can pile up.
A GTM expert regularly audits your container to clean up what’s outdated, avoid conflicts, and keep everything organized.
They follow naming rules and leave notes so anyone can understand what each tag or trigger does.
Tracking rules and tools change often.
A good GTM expert keeps up with new features like Consent Mode, privacy rules like ITP, and shifts to server-side tracking.
The Stape Care team tracks these changes closely and helps businesses stay compliant and adapt to new requirements.
This means fewer risks of Meta restrictions, blocked Google accounts, or other penalties.
Platforms like Stape take compliance seriously to keep your tracking and your campaigns running without disruption.
Stape Cookie Keeper, for example, helps manage consent and extend cookie lifespan to reduce data loss and keep tracking stable.
If your business runs ads, collects leads, or sells online, you need reliable tracking to make the right decisions.
A GTM expert helps you get that.
Whether it's a one-time setup or ongoing support, services like Stape Care give you expert help without hiring full-time.
Here's who benefits most from working with a GTM specialist:
If you run ads on Google, Meta, TikTok, or Snapchat you need to know which platform drives real results. A GTM specialist will set up proper tracking so you can see which campaigns lead to purchases or sign-ups.
This helps ad platforms optimize better and saves your budget from going to waste.
If you already handle content, campaigns, and strategy, a GTM expert can take care of the tracking setup and event logic.
A GTM expert will map each step of your funnel, from product views to purchases, and send clean data to GA4 or your CRM.
You get clear reports without having to figure out how to build them.
A GTM expert will set up detailed eCommerce tracking, so you can measure actions like scrolls, clicks, cart adds, and purchases.
They'll also set up remarketing tags, value-based audiences, and custom conversions.
These advanced setups help improve your return on ad spend.
Their services let agencies offer a high-quality tracking setup as part of the service.
Many agencies work directly with Stape Care specialists to implement high-quality server-side tracking via server GTM container.
Our server GTM container setup guide explains how to build reliable server-side tracking that protects your data and improves attribution.
N.B.: If your business needs to follow privacy laws like GDPR or CCPA, a GTM expert can make sure your tracking is compliant.
They'll configure consent banners, set up Google Consent Mode, and make sure no tags fire without permission.
This helps you stay safe legally and build trust with users.
Overall, any business that uses data to guide decisions can benefit from working with a GTM expert. They help you collect reliable data, stay compliant, and improve results across your marketing tools.
If your team is launching something new, running into tracking issues, or moving to a more advanced setup, expert help can save time, budget, and give better data quality.
The best time to get tracking right is before your site goes live.
If you're building something new or going through a full redesign, a GTM expert can install all your key tracking: GA4 events, Facebook events, Google Ads conversions, CRM tags, and more from day one.
This ensures you don't lose any data in the first few days or weeks.
Stape Care often supports businesses during these launches to make sure everything is measured correctly from the start.
Launching a seasonal promo, adding a new ad network, or testing TikTok Ads?
A GTM expert will make sure all the right events are tracked and that your landing pages, custom goals, and tag configurations match your campaign goals.
They also handle affiliate tracking, remarketing tags, or new funnel events, so everything you test brings real data back.
If you're switching from Universal Analytics (an older version of GA) to GA4 or moving to tools like Segment or Amplitude, it's a good time to call in a GTM expert.
They'll plan your migration, update your tag setup, and make sure all data points are mapped correctly.
Without help, you risk broken reports or missing metrics during the transition.
If one platform shows 50 conversions and another shows 30, or your revenue totals don't match across tools, it's time for a tracking audit.
A GTM expert will review your setup, inspect tags, debug data layers, and fix what's broken.
Stape Care offers one-time audits that include a full report and a follow-up call to walk you through the insights.
If you want better data accuracy, stronger attribution, or more control over tracking, server-side GTM is the next step.
A GTM expert will install your server container, configure endpoints for GA4 and Meta CAPI, and connect everything to your front end.
Stape Care has helped hundreds of businesses move to server-side GTM and knows how to handle even complex setups like multi-domain tracking or advanced eCommerce tagging.
Sometimes, your team just doesn’t have time.
If marketers are stuck troubleshooting tracking issues or trying to learn GTM from scratch, it slows everything down.
Bringing in a specialist, even for a few hours, can keep your campaigns on schedule and prevent missed opportunities.
Overall, it’s worth hiring a GTM expert as the tracking issues can lead to wrong decisions, wasted ad spend, or compliance risks.
If your company has tracking needs, one key decision is whether to bring someone in-house or work with an external specialist.
Both options can work well. The best choice depends on how often you need help, how complex your setup is, and what internal resources you already have.
An in-house tracking expert is part of your team full-time. That means they're always available when something needs fixing or adjusting.
If your site breaks or your conversions drop suddenly, they can look into it right away.
Over time, they also learn your systems, your naming rules, and your funnel logic.
That context helps avoid mistakes and makes it easier to adapt tracking when your campaigns evolve.
It's also easier for them to collaborate with your marketing, product, or dev teams since they're involved in everyday planning and discussions.
But hiring a full-time expert isn't cheap. You'll need to cover salary, benefits, and possibly onboarding or training.
It also assumes you have a steady flow of work.
Many companies don't have enough tracking needs to keep someone busy 40 hours a week.
Another limit is expertise. One person can't know everything. They might be strong in GA4 and GTM but struggle with tools like Segment or Amplitude.
That’s where external help makes sense.
An agency gives you access to a broader skill set without a long-term commitment.
You can book them for a one-off audit, a specific implementation, or ongoing support.
This gives you flexibility and lowers the cost if your needs are seasonal or project-based.
Agencies like Stape Care bring a whole team.
That means they've likely seen your problem before and can solve it fast.
They also stay up to date with new tracking methods like server-side GTM, Meta Conversions API, or Consent Mode.
With Stape Care, you can also choose a retainer plan that includes setup, monitoring, and fixes, with priority response through channels like Slack.
Overall, it comes down to how often you need support. If tracking is core to your operations and you have the budget, go in-house. If your needs are project-based, agency help is often the smarter path.
The person or team setting up your tracking will handle data that shapes your marketing decisions.
If something's set up wrong, your campaigns won't just lose performance, they'll lead you in the wrong direction.
That's why it's worth choosing someone with experience, clear communication, and the right skill set for your stack.
How many setups have they handled? Have they worked with companies of your size? Do they know your industry?
Someone who's set up GA4 and GTM for 50+ eCommerce sites will likely get your needs faster than someone who’s only done blogs or apps.
Agencies like Stape Care list over 1000 completed tracking setups. That kind of scale usually means they've seen issues like yours before and solved them.
GTM is just one part of the puzzle.
A good specialist will also know Meta and Google Ads tracking, consent setups, debugging with DevTools, and how to work with JavaScript or dataLayer.
If you're using Segment, Amplitude, or Adobe Analytics, check for that too. The more overlap with your stack, the better.
Ask if they've handled GDPR or CCPA compliance before.
They should know how to configure Consent Mode, delay tags until consent is given, or integrate with CMPs.
If they hesitate when you mention things like “prior consent triggers,” it may be a red flag.
Stape Care, for example, includes consent-safe tracking in most server-side GTM projects.
You don't want a black-box setup.
A good expert will walk you through what they've done in clear language.
You'll often get documentation or a call to review changes.
This is especially helpful if you're managing tracking long-term or want your team to learn from the setup.
If it's a one-time project, check their availability and timelines.
If you need help regularly, see if they offer ongoing support or retainers.
Good freelancers typically charge $30–$60 per hour. Some offer project pricing, others go hourly. Just make sure you understand what’s included.
One might charge $500 for a basic setup. Another might quote $1500 but offer documentation and 30 days of support.
Ask questions, compare offers, and pick what's right for your team.
Have them audit your GTM or fix one issue.
See how they communicate. Check if their work is clean and delivered on time.
This quick trial can help you decide if you want to keep working with them.
LinkedIn, Upwork, or agency case studies can show how others rate their work.
For example, some Stape Care clients report improved tracking accuracy and better ROAS within a few weeks of cleanup.
You don't need someone who knows everything. You need someone who knows what matters for your setup.
If they show interest in your business goals and ask the right questions, that's a strong signal they'll build something reliable.
GTM sits between marketing and development. It's not just a dev tool, and it's not just for marketers.
That's why it's best handled by someone who understands both.
In small teams, a marketer with tech knowledge might take care of basic tasks. But as tracking gets more complex, the job needs a dedicated expert.
That might be a GTM consultant or an agency, such as Stape Care.
The right person knows how to translate marketing needs into working tag setups.
They know where to place a trigger, how to read the dataLayer, and how to test before publishing.
Pricing depends on what you need and who you hire.
For short-term or project-based work, most GTM consultants charge between $30 and $50 per hour. Those with rare skills or deep experience can charge more.
If you prefer a fixed fee, a basic setup might cost a few hundred dollars. A full eCommerce setup with 20+ tags, server-side tracking, and custom events could be $1,000 or more.
Agencies like Stape Care offer packages starting around €700 for a full tracking setup and from €500 for audits. Monthly retainers are also available, starting from €1199. These typically include hands-on support, monitoring, and priority responses.
For a full-time in-house expert, salaries in the US or Western Europe typically range from $70,000 to $100,000 per year.
Yes. GTM experts can connect your Consent Management Platform (CMP) to GTM, delay tags until consent is given, and make sure your setup stays compliant with GDPR, CCPA, or other local laws.
A typical setup includes things like:
A good expert will also help you choose which tags are essential, block personal data when needed, and avoid data loss when users opt out.
If you're implementing Consent Mode, they’ll make sure GTM adjusts how data is sent based on consent status.
Stape Care includes privacy-safe tracking in most projects.
They've worked with CMPs, complex consent flows, and cookieless setups across dozens of industries.
So, if you're unsure how to stay compliant and still track conversions, this is exactly where a GTM expert helps.
Good tracking leads to better marketing decisions.
Here's what a GTM expert actually helps you do:
See which campaigns drive real actions, not just clicks or visits.
Send complete conversion data to Meta or Google Ads so they can optimize.
Track where users drop off and improve forms, pages, or flows.
Track which version users saw and what worked best.
Fix broken tags or missing events before they hurt your results.
Launch campaigns without waiting for tracking fixes.
Many teams work with Stape Care to get this kind of support without hiring in-house.
You get expert help when you need it and better results from every campaign.
A GTM expert makes sure your data reflects what users actually do on your site.
They make sure you don't waste your budget on incomplete data, miss key signals, or lose conversions you didn't know were happening.
With the right tracking in place, your campaigns become easier to test, improve, and scale.
You get faster feedback, stronger results, and a setup you can trust to make your business decisions on.
That's what Stape Care does for clients every day: make marketing measurable, efficient, and smarter.
