Expert GA4 setup
Marc Alexander sets up GA4 and Google Tag Manager from a written measurement plan: your key events, ecommerce or lead tracking, Consent Mode v2 and ad platforms, tested before launch and documented.
What you get.
Basic setup, £350 to £600, 2 to 3 weeks. For one website with straightforward ecommerce or lead generation.
- GA4 property and Google Tag Manager configured
- Key events for the actions that matter
- Ecommerce or lead generation tracking
- Consent Mode v2
- Google Ads and Search Console linked
- Documentation and 1 hour of training
Advanced setup, £850 to £1,300, 4 to 6 weeks, adds custom event design, item-level ecommerce, cross-domain tracking, wider testing and 2 to 3 hours of training.
Priced separately: server-side GTM (from £2,000), BigQuery (from £500), dashboards (from £800) and CRM integration (from £1,500).
How it works.
Plan
Marc talks to the people who will use the data, maps goals to key events and writes the measurement plan. Nothing touches the live site yet.
Build
Events, ecommerce or lead tracking, consent, cross-domain settings and platform links are built in Google Tag Manager and tested in preview.
Test
Real journeys are tested across devices and browsers, and GA4 is compared with your other data sources before and after launch.
Hand over
Training, an event dictionary and documentation, so the setup doesn't depend on Marc to keep working.
Straight answers.
What's the difference between basic and advanced?
Basic (£350 to £600) suits one website with straightforward ecommerce or lead tracking. Advanced (£850 to £1,300) adds custom event design, detailed ecommerce tracking, cross-domain tracking and more training. Neither includes server-side GTM, BigQuery, CRM integration or dashboards: those are priced separately.
We already have GA4. Do we need a new setup?
Not necessarily. Often it's cheaper to fix what's there. A GA4 mini audit (from £175) or the 38-point audit will tell you whether fixing or rebuilding makes more sense.
How long does it take?
Basic setup takes 2 to 3 weeks, advanced 4 to 6 weeks. Most of the variation comes from how quickly developers and approvers can respond.
Is training included?
Yes: 1 hour with the basic setup, 2 to 3 hours with advanced, plus written documentation.
How does it handle privacy law?
Every setup includes Consent Mode v2, configured so tracking follows the visitor's choice under UK GDPR, PECR and the Data Protection Act 2018.
What about changes after handover?
Small changes can be quoted as one-off work. For regular changes and monitoring there's a monthly retainer, from £500 a month.
More detail: what the measurement plan covers
- Ecommerce: the full event chain from view_item to purchase, with item data, currency and quantity, refunds, and attribution that survives payment gateway redirects. The aim is GA4 revenue that lines up with Shopify, WooCommerce or Stripe.
- Consent: Google Consent Mode v2 that changes what is collected based on the visitor's choice, with sensible defaults for UK and EU visitors.
- Cross-domain journeys: cross-domain linking and referral exclusions, so a visitor moving from your site to a checkout or booking domain stays one visitor and the sale keeps its source.
- Ad platforms: GA4 linked to Google Ads with key events imported, enhanced conversions where consent allows, clean UTM standards and deduplication so nothing is counted twice.
- Event design: one naming scheme for events and parameters, based on what the business needs to report on, written down in an event dictionary.
- Lead generation: high-intent actions tracked as key events, with IDs that can later connect a form submission to a closed deal in your CRM.
Running an app as well as a site, or several brands and regions? Aligning events and user IDs across them is quoted separately, after an intro call.
How consent, the dataLayer, GTM and server-side tagging fit together: the best tracking architecture for a website.
