    CONVERSION TRACKING& ANALYTICS THAT HOLD UP

    If the measurement is wrong, the budget decisions built on it are wrong too. Our data and analytics team builds the conversion tracking, offline imports, attribution and reporting that your bidding systems and budget decisions rely on.

    Bad numbers start in the tracking code

    In the first week we review tags the way engineers review a pull request. These three files are a composite of recurring findings: ten implementation faults across Google Tag Manager, page code and pixel setup, each one throwing the reported numbers off.

    Bug · line 5

    Purchase fires on every page load

    There is no guard against refreshes or back-button visits, so the event repeats on every render of the page. On this template, one order in five was recorded twice.

    2

    Bug · line 7

    Conversion value is undefined

    Value-based bidding is enabled, but every conversion arrives without a value. Smart Bidding receives no revenue signal and optimises toward conversion count.

    3

    Bug · line 14

    No transaction_id, no dedupe

    Without a dedupe key, Google Ads and the weekly report both count the same order as many times as it renders.

    Findings 1 and 3 record the same order in two different files. The duplication is only visible when the files are reviewed together.

    The 90 days after the fix

    The audit is the first two weeks. The value builds afterwards, once bidding, budgets and testing are running on reliable numbers.

    Marketing analytics services, implementation through reporting

    Six disciplines across the four stages below. Everything is built in your accounts and documented for your team.

    01GA4 and Google Tag Manager implementation

    Events, conversions and consent built properly: deduplicated actions, clean parameters, and a GTM container that remains maintainable. Everything else depends on getting this layer right.

    ga4 · gtm · consent-mode

    02Conversion values and value-based bidding

    Revenue, margin or lead-quality values attached to every conversion that matters, so Smart Bidding optimises toward profit rather than conversion count, the work behind the results we publish.

    03Offline conversion tracking and CRM feedback

    When revenue closes on a call, in a pipeline, or months later, we wire it back: click IDs captured, CRM stages mapped, and offline conversions imported so the platforms learn from real outcomes.

    04Attribution and contribution analysis

    Last-click attribution overstates some campaigns and understates others. We separate brand from non-brand, quantify assisted demand, and show what each channel contributes to a sale.

    05Dashboards and reporting pipelines

    Custom dashboards on top of warehouse-grade data (GA4, Google Ads, Search Console and CRM exports in BigQuery) scoped to the decisions made monthly rather than to every available metric.

    06Experimentation and forecasting

    We work out how big a test needs to be and how long it will run, forecast budgets up front, and read results against the same statistical methodology behind our public calculators.

    Lead generation and ecommerce measure differently

    Offline conversion tracking decides whether lead gen works; deduped values decide whether ecommerce tracking can be trusted. The pipeline is shared; the implementation differs at every stage.

    The outcome that matters

    Lead generation

    Sales-accepted leads, booked meetings and closed pipeline.

    Ecommerce

    Margin-adjusted revenue and returning-customer rate.

    Where measurement typically fails

    Lead generation

    All enquiries counted equally, so low-quality leads inflate apparent growth.

    Ecommerce

    Duplicate purchase events, refunds left unsubtracted, brand campaigns credited with existing demand.

    What we wire in

    Lead generation

    Click IDs on every lead, CRM stages mapped, offline conversion imports.

    Ecommerce

    Deduped purchase events with real values, feed data, refund handling.

    What bidding learns

    Lead generation

    Which clicks become customers, so budget allocation follows lead quality.

    Ecommerce

    Which products and audiences are profitable across seasonal cycles.

    Proof it works

    Lead generation

    28% lead-quality lift and 127% more enrolments at Arden University.

    Ecommerce

    14:1 ROAS and 176% PPC sales growth at Dobbies.

    Most of our clients sell through both. The two set-ups run side by side and feed our paid search management and paid social work on the same accounts.See both in the case studies

    Proprietary tooling, built on the same measurement

    The team that wires your measurement also builds our own tooling on top of it, monitoring accounts continuously between reporting cycles.

    The shape of the Arden result: once enrolment data reached the bidding system, budget reallocated toward enrolment likelihood.

    Enrolment data was wired back into the ad platforms so bidding could optimise toward enrolment likelihood rather than enquiry volume. Every result below comes from that measurement work.

    Three ways to work together, each with a clear end point

    Each one has a clear end point. A lot of accounts need two weeks of focused work rather than an ongoing retainer, and all three start with the same free review.

    01

    The audit sprint

    Two weeks of focused work: tags, code, containers and CRM path read end to end, every finding written up in plain English with the restated numbers beside it.

    Ends with:the fix list, the restatement, and a recommendation on whether further work is needed.

    02

    The rebuild

    We implement the fix list: events and values rebuilt, offline conversions wired in, dashboards stood up, all in your accounts, documented for your team.

    Ends with:measurement your team and your bidding can both trust.

    03

    The measurement partner

    Ongoing experimentation, reporting and value-bidding tuning, usually alongside our paid media teams working the same account.

    Ends with:a quarterly review against agreed outcomes.

    Data & analytics FAQs

    Straight answers on conversion tracking, GA4, offline conversions and reporting. The same measurement thinking powers our free PPC tools and every case study we publish.

    Q.

    Can you audit our existing conversion tracking?

    A.

    Yes. It is where every engagement starts. We check GA4 and Google Tag Manager events, deduplication, conversion values, consent handling, and what the ad platforms are actually being taught, then hand back a prioritised fix list in plain English.

    Get a free tracking review
    Q.

    Do you set up GA4 and Google Tag Manager?

    A.

    Yes. Implementation, migration cleanup, event design, ecommerce tracking, and consent configuration, built in your own accounts, documented so your team can maintain it, and verified against real transactions rather than test pings.

    Q.

    Can you connect our CRM to Google Ads?

    A.

    Yes. Offline conversion tracking is one of the highest-leverage fixes in paid media: click IDs captured on every lead, CRM stages mapped to conversion actions, and closed revenue imported back so Smart Bidding optimises to customers rather than form fills.

    Read the GCLID capture walkthrough
    Q.

    Who owns the data and the accounts?

    A.

    You do. GA4, Tag Manager, ad accounts, dashboards and any warehouse pipelines are built in your properties under your ownership. If we ever part ways, everything keeps working and stays with you.

    Q.

    What dashboards and reporting do you build?

    A.

    Decision-led dashboards on top of clean data: paid media performance tied to revenue or pipeline, brand and non-brand separated, and the small set of figures a board actually reviews.

    Q.

    How much does analytics and tracking work cost?

    A.

    It depends on the state of the current setup and how much needs rebuilding versus verifying. The free tracking review scopes it honestly; many accounts need two weeks of focused work rather than an ongoing retainer.

    Start with the free review
    Q.

    Can you work alongside our in-house developers or another agency?

    A.

    Yes. Most tracking work ships through someone else’s release process. We write the specs, the dataLayer contracts and the GTM changes, your developers deploy on their schedule, and we verify against real transactions afterwards.

    Q.

    How long does a tracking rebuild take?

    A.

    The audit sprint is two weeks. A typical rebuild (events, values, offline imports, dashboards) usually lands within one to two months depending on release cycles and CRM access. The free review gives you a scoped answer for your setup.

    See rebuilds inside the case studies
    Q.

    Do you audit Meta and Conversions API as well as Google?

    A.

    Yes. Pixel and Conversions API events get the same treatment as GA4 and Google Ads: deduplication between browser and server events, real values, and exclusion of low-quality signals, so Meta optimises toward completed customers rather than click-stage events.
