GA4 and Google Tag Manager setup for SMEs
Most GA4 properties were migrated in a hurry and have never been checked. I audit what you have, write a measurement plan around the actions that matter to your business, and rebuild the tracking in Google Tag Manager so every number means what you think it means.
Measurement plan mapped to your business goals
GA4 property and GTM container configured and documented
Consent Mode v2 and UK GDPR-aware setup
What is included
- Tracking audit. I read your current GA4 property, GTM container and site code and list what is broken, duplicated, missing or misleading.
- Measurement plan. A one-page document that names the 8 to 15 events your business needs (purchases, enquiries, quotes, sign-ups, calls, downloads) and defines each one precisely.
- Rebuild in Google Tag Manager. Events, parameters, ecommerce data layer, cross-domain tracking, internal traffic filters and conversion events, all configured in GTM so your developers are not needed for every change.
- Consent Mode v2. Tracking wired to your cookie banner so you stay on the right side of UK GDPR and PECR and keep modelled conversions in Google Ads.
- Google Ads and Search Console linking. So paid and organic performance are visible in the same place.
- Handover. A written record of every tag, trigger and variable, plus a 45-minute walkthrough recorded for your team.
Platforms I work with
- Shopify, WooCommerce, Magento / Adobe Commerce, BigCommerce and custom ecommerce builds
- WordPress, Webflow, Squarespace, HubSpot CMS and bespoke sites
- Single-page apps in React, Vue or Next.js, where GA4 needs a virtual page-view model
- Server-side tagging on Google Cloud or Stape when ad blockers or Safari ITP are hurting your data
How long it takes
- Audit and measurement plan: within one week of access being granted.
- Build, test and handover: one to two further weeks depending on platform and the number of events.
- Everything is fixed scope and fixed price, agreed before any work starts.
Questions about this service
How much does a GA4 and GTM setup cost?
It is a fixed price agreed before work starts, based on your platform and the number of events in the measurement plan. A single-site setup for a typical SME is a project measured in days, not months. Book a free call and I will give you a figure on the same day.
Do I need Google Tag Manager if I already have GA4?
You can run GA4 without GTM, but you should not. GTM lets you add and change tracking without touching site code, keeps every tag documented, and makes Consent Mode, enhanced conversions and server-side tagging possible later. If you only have the GA4 snippet, I will move you to GTM as part of the setup.
Is Google Analytics 4 compliant with UK GDPR?
GA4 can be run in a way that is compatible with UK GDPR and PECR, but only if consent is collected before tracking fires, IP anonymisation and data retention settings are correct, and Google Signals is used deliberately. Consent Mode v2 configuration is part of every setup I do. I am not a lawyer; where your situation is unusual I will tell you to take legal advice.
