Analytics & tracking

GA4, Tag Manager and conversion tracking

Marketing decisions are only as good as the data behind them

Inaccurate tracking does not just produce untidy reports – it trains bidding algorithms on the wrong signals and sends budget to the wrong places. We set up measurement properly, then turn it into reporting people can act on.

Why tracking comes first

The cost of bad measurement

Duplicate conversions, form thank-you pages counted twice, transactions missing revenue values, cross-domain journeys breaking sessions, or a tag firing on every page load – each of these quietly distorts the picture. When smart bidding is optimising to that data, the errors get amplified with spend behind them.

We start by validating what is currently being recorded against what actually happened in your order or CRM system. Once numbers can be trusted, everything downstream – budget allocation, channel comparison, testing, forecasting – becomes far more useful.

From audit to monitoring

How we work

  1. 01

    Audit current tracking

    What is recorded, what is missing, what is double-counted and how far it sits from reality.

  2. 02

    Define the measurement plan

    The events, values and dimensions that map to your commercial questions.

  3. 03

    Implement and validate

    Tags, data layer and platform integrations, tested before anyone reports from them.

  4. 04

    Build the reporting layer

    Dashboards and reports for the specific decisions each audience needs to make.

  5. 05

    Monitor

    Ongoing checks so a site release does not silently break measurement.

Client results

Results and evidence

Prestige Wicker, a Shopify retailer selling wicker products, had run no social activity for two years. Its store, product catalogue and tracking had to work together before catalogue advertising and retargeting could be used properly, so we connected them first and built the campaigns on top. We report on every account against commercial results, not platform activity.

What we did for Prestige Wicker

  • Set up Facebook Shop and connected the Shopify product catalogue
  • Implemented Facebook Pixel tracking through Events Manager, bringing products and website activity together
  • Moved from traffic ads to retargeting and catalogue ads once the Shop, catalogue and Pixel worked together

Ecommerce / lingerie store

7%

Increase in paid search revenue

Conversion tracking fixed before optimising Google Ads

Our PPC audit found several tracking codes installed at once, exaggerating results in Google Ads compared with Google Analytics. We replaced them with a single code, then improved ads, keywords and bidding. Paid search revenue rose 7% month on month.

Consent-aware tracking that keeps reporting usable

We implemented CookieYes banners across client sites and configured Consent Mode v2, so GA4 and Google Ads adjust to each visitor’s choice and model the gaps when cookies are declined.

Good to know

Frequently asked questions

Why do our platform numbers never match GA4?

They measure differently. Ad platforms credit themselves using their own attribution windows and modelling; GA4 applies its own model. Both can be useful once you understand the gap and agree which number decides budget.

Can you set up GA4 and Google Tag Manager from scratch?

Yes – including event and conversion design, ecommerce tracking, cross-domain set-up, and documentation so your team knows what each event means.

Do you handle consent and privacy requirements?

We implement consent-aware tracking, including consent mode where appropriate, so measurement respects user choices while still giving you usable data.

What is server-side tracking and do we need it?

It sends event data from a server rather than the browser, improving data quality where browser restrictions bite. It is worth it for higher-spend accounts; for smaller ones the effort often outweighs the gain.

Can you build reporting our board will actually read?

Yes. Dashboards focused on the small number of commercial metrics that drive decisions, with commentary rather than an unexplained wall of charts.
