GA4 · Google Tag Manager

E‑commerce analytics and GA4 setup

Missing orders, duplicated purchases and an incomplete purchase path make it hard to assess how your store is doing. I check your analytics, fix errors or set up tracking from scratch, so you can make decisions based on reliable data.

Auditing and implementing e-commerce analytics in Google Analytics 4 and Google Tag Manager.

Why doesn't GA4 data match your store dashboard?

Google Analytics 4

Analytics can collect data every day and still show an incomplete or distorted picture of sales. Errors often only come to light when you compare reports with orders or try to figure out why customers aren't buying.

Your tracking is worth a closer look if:

  • The number of orders or revenue in GA4 raises doubts. You don't know where the differences from your store dashboard come from or whether they are within tracking limitations.
  • You can see sales, but not the whole path to purchase. Data on product views, add-to-cart or checkout starts is missing.
  • You're not sure where purchases come from. Reports show payment providers, unrecognized sources or changes that are hard to explain.
  • Your store went through a migration or bigger changes. After changing the platform, the checkout process or the consent banner, tracking may have stopped working correctly.
  • Analytics was connected, but nobody checked it. You have no confirmation that it records the right events and passes the right values.

Analytics audit and fixes

You already have GA4, but you need to check whether the data is correct and sufficient to assess store performance.

I review the configuration and how tracking works along the purchase path. I explain the discrepancies found, point out missing information and implement the agreed fixes. Then I test whether data reaches analytics as intended.

Tracking set up from scratch

Your store doesn't have analytics yet and you want to start measuring sales

I define what information you need to make decisions in your store. I configure GA4 and Google Tag Manager, implement e-commerce events and verify that they work. You get documented tracking and a walkthrough of the reports you can use in your daily work.

What do I check in a tracking audit?

Correct purchase tracking

I check whether a purchase is recorded at the right moment, only once and with the correct value. I also verify that product, currency and transaction ID information is passed on.

The full purchase path

I implement or fix tracking of the key stages: product view, add to cart, checkout start and purchase. This lets you see between which steps you lose the most shoppers.

Traffic sources and campaigns

I verify how analytics attributes visits and purchases to traffic sources. I check campaign tagging and whether cross-domain navigation and returns from payment pages distort the data.

GA4 and GTM configuration

I tidy up the settings, tags and triggers responsible for collecting data. I check that tracking fires where it should and that different integrations do not record the same events multiple times.

Consent and Consent Mode

I check how tracking reacts to accepting, rejecting and changing consent. I verify the technical integration with the consent banner and the Consent Mode configuration within the agreed scope.

Reports and data interpretation

I prepare the agreed reports on sales and the purchase path. I show you how to use them, which limitations to keep in mind and which data needs further analysis.

What do you gain from well-organized analytics?

  • More confidence in your data

    You understand what analytics measures, which errors were removed and where any remaining differences may come from. It is easier to assess results without wondering whether a change in a report is a tracking error.

  • A visible path to purchase

    You can compare the stages of the purchase and identify the places that need analysis. It is a concrete starting point for checking what stops customers from moving forward.

  • Measuring the effect of changes

    Organized tracking lets you follow results after changes go live. You also know from when the data can be compared and what limitations to consider when interpreting it.

  • Control over your analytics

    The accounts and configuration stay with you. You get documentation and a walkthrough of the implementation, so you can use the tracking yourself or with a team of your choice.

Setting up e-commerce tracking in GA4 step by step

  1. Call and scoping

    We talk about your store, the current setup and the problems you notice. We agree on the scope of work, the access needed and how it will be billed.

  2. Audit or tracking plan

    I audit the existing analytics or prepare a plan for a new implementation. I define what needs fixing and which events should be measured.

  3. Implementation and testing

    I configure tracking and make the agreed fixes. I go through the purchase path, checking events, the values sent and how tracking behaves under different consent settings.

  4. Documentation and walkthrough

    You get a summary of the work done, documentation and information about tracking limitations. At a meeting I show you where to find the data you need and how to use it.

How much does e-commerce analytics cost?

The price depends on the store platform, the state of the current setup and the scope of tracking needed. Additional domains, language versions and custom elements of the purchase path also matter.

After an initial review you'll get the scope of work and a quote before anything starts. You can hire me for a one-off analytics cleanup without committing to ongoing cooperation.

Frequently asked questions

Do you implement fixes after the audit?
Yes. I also fix the errors found during the audit. I discuss with you what needs fixing, agree on the scope of work and, after the changes are implemented, check that everything works correctly.
Which tools do you need access to?
Most often Google Analytics 4, Google Tag Manager, the store platform and the consent management tool. I'll give you the exact list and the level of permissions needed once the scope of work is agreed.
How long does an analytics audit or implementation take?
I set the timeline after reviewing the scope and the current setup. It depends on the number of changes needed, the store's technical possibilities and the availability of the people who maintain it. You'll know the schedule before work starts.
Will you help me understand the data after implementation?
Yes. During a meeting I'll show you where to find the most important information about sales and the purchase path, how to read the reports and what to look for when assessing your store's results.

During the free consultation we'll go through your current setup, the problems you've noticed and the questions you want answered. Based on that, I'll determine what scope of audit or implementation makes sense for your store.
