Tracking & Measurement Audit

Your analytics is measuring a fraction of your business.

An independent audit of the Drive Medical tracking stack — Google Analytics 4, Google Tag Manager, Google Ads and Meta — against the setup the previous agency was contracted to deliver.

Why This Matters

Measurement is not a reporting formality — it is the input your business runs on.

Every marketing decision and every advertising dollar is only as good as the data behind it. When tracking is incomplete or wrong, the damage is rarely visible on a dashboard — it shows up as budget spent in the wrong places and opportunities never seen. That impact falls into two categories.

01 · Indirect impact

Better data means better decisions

Marketeers steers budget, channels, product focus and priorities based on what the numbers appear to say. If those numbers understate some sites, inflate others, or miss conversions entirely, the resulting decisions are subtly — but consistently — wrong.

Over a year, a series of slightly mis-informed calls about where to invest compounds into a meaningful drag on growth. This cost never appears as a line item, which is exactly why it goes unmanaged.

02 · Direct impact

Ad algorithms are only as smart as the conversions you feed them

Google and Meta bidding is machine learning: it optimises toward the conversion data your site sends back. Feed it complete, accurate purchase and lead signals and it finds more of your best customers at a lower cost. Feed it partial, zero-value or duplicated data and it learns the wrong lesson — spending on the wrong people while the real winners go unnoticed.

This is a direct, measurable loss: the same budget simply buys fewer results. It is the effect quantified throughout this audit.

Executive Summary

The foundation of your digital decision-making is not reliable today.

Drive Medical operates eight websites that should feed one central analytics account. Across all of them, we found 21 findings that fall into four recurring core problems, plus a set of foundational gaps. Together they explain why the numbers used to steer marketing spend cannot be relied on today. The estimated annual cost is shown per problem area, based on the media-spend assumption further below.

No proper conversion tracking

Revenue is missing from purchase tracking, and conversions are partly missing, partly counted twice. Campaign performance and return on ad spend cannot be calculated from these numbers.

{{ m1 }}
{{ c1 }}
Missing data in analytics and dashboards

Three sites report nothing at all, and important soft-conversion and non-commerce events are absent — site search, form submissions, lead enquiries. The dashboards built on top cannot be validated against the source.

{{ m2 }}
{{ c2 }}
Browser tracking prevention distorts the data

With no server-side tagging in place, a growing share of conversions never reaches Google and Meta, and journeys break at the checkout hand-off. Attribution reporting is distorted and bidding is trained on incomplete signal.

{{ m3 }}
{{ c3 }}
A patchwork implementation

Tracking is a mixture of tags, hard-coded scripts and plugins spread across separate accounts and containers. There is no straightforward way to validate, maintain or extend it when the business needs a change.

{{ m4 }}
{{ c4 }}
Other foundational gaps

Short data-retention settings, Search Console coverage for only one domain, and no raw-data export. No direct media cost, but each one limits what can be analysed later.

Financial Impact

What these gaps cost you every year

The estimates below translate each finding into a share of annual paid-media spend that is being wasted or left on the table — through misallocated budget, un-optimised bidding, and conversions the ad platforms never see. They are illustrative benchmarks for US medical e-commerce, sized against the assumptions shown. Enter your actual figures (via the Tweaks panel) to recalculate.

Adjust the assumptions — enter Drive Medical’s actual figures and every estimate recalculates instantly.

Ranges are directional and non-additive with precision — they indicate order of magnitude, not a guaranteed figure. Foundational findings that enable measurement (retention, Search Console, raw-data export) are marked Indirect and not counted in the total to avoid double-counting.

The Path Forward

A phased remediation roadmap

Sequenced by priority over a 12-month engagement: all nine critical findings are resolved in the first three months, the most important urgent items follow in months 3–6, and the remaining urgent items and issues are handled in months 6–12. Every three months we hold a joint prioritisation meeting to review progress and re-order what comes next. Alongside all three phases we provide continuous support and advisory as your dedicated measurement partner.

Fix the critical foundation
All 9 Critical findings — F01, F03, F04, F05, F07, F09, F11, F14, F21
We rebuild the tracking structure, ensure consistent data is captured everywhere, and unify and centralise the tagging system.
  • Consolidate scattered GA4 properties & GTM containers under central ownership
  • Deploy tracking on the 3 untracked domains
  • Fix the purchase event: real value, currency, order ID and items
  • De-duplicate purchase / page_view firing
  • Restore key events, Google Ads conversions (off HubSpot) & GA4 audiences
  • Stand up server-side GTM and route GA4 / Ads / Meta through it
  • Implement proper internal search tracking
Phase 2 · Months 3–6
Elevate tracking quality & reporting
The most important Urgent findings — F02, F08, F15, F16
We close the remaining data gaps in lead and non-commerce measurement, and build one validated, decision-ready dashboard on top of the repaired foundation.
  • Complete data collection on the sites still reporting nothing
  • Implement form-submission & lead tracking in both containers
  • Reconcile the Looker Studio dashboard against validated GA4 data
  • Add the missing commercial views: revenue by channel, new vs. returning
Phase 3 · Months 6–12
Extend & maintain
Remaining Urgent items and all Issues
We roll out the remaining channel connections and governance items, and keep the stack aligned to your evolving needs through ongoing maintenance.
  • Conversions-API connections for every remaining paid channel, incl. Meta Pixel + CAPI
  • Cross-domain tracking across all Drive domains
  • Data retention, Search Console coverage & GA4 raw-data export to BigQuery
  • Offline-conversion tracking for leads & soft conversions
  • Further Optimizations and extensions of the tracking stack, based on new requirements discovered in the first two phases
  • Ongoing maintenance & adjustments to the client's requirements
Across all three phases — your ongoing measurement partner
Quarterly prioritisation meeting

Every three months we review what has been delivered and re-prioritise the backlog together. The sequence below is a plan, not a fixed contract — new business requirements or findings can move items forward.

Maintenance, extension & support

First-, second- and third-level support across all Google and further measurement products — so the stack stays healthy as your business and the platforms evolve.

Advisory for your marketing teams

Hands-on measurement guidance for both the paid and organic marketing teams, so they can act on trustworthy data with confidence.
