Talk to a Marketing ExpertEvery ad platform claims credit for your sales, and together they often claim more sales than you actually made. We build reliable tracking and a sensible attribution approach so you can see which channels, campaigns and messages genuinely create customers, and invest accordingly.
Customers rarely buy after a single interaction. They might see an Instagram ad, search your brand name a week later, read a comparison article, get a retargeting ad, and finally convert from an email. Which channel deserves the credit?
Each platform answers that question in its own favour. Meta counts conversions after ad views and clicks within its attribution window; Google Ads counts its own clicks; your email tool counts its own clicks. Add them up and the total often exceeds your actual sales. Meanwhile, privacy changes, cookie restrictions and consent choices mean every tool sees only part of each journey.
There's no perfect answer, but there is a sensible one: reliable tracking as the foundation, one consistent view of conversions across channels, and tests that measure what each channel genuinely adds. That's what we build.
Fixing measurement rarely requires expensive software. In most businesses, the biggest improvements come from consistent campaign tagging, correctly configured conversions, and connecting sales outcomes back to marketing data.
Tracking and attribution sits within our marketing analytics services, alongside Google Analytics setup and reporting dashboards.
Attribution is only as good as the data underneath it. We start by making tracking complete and consistent.
Clear naming rules and a shared builder so every campaign link is tagged consistently.
A well-organised Google Tag Manager setup covering analytics and ad platforms.
Tags routed through your own server container for more control, resilience and data quality.
Server-to-server events for Meta, LinkedIn and other platforms, deduplicated with browser events.
Hashed first-party data, with consent, to improve conversion matching in Google Ads.
Qualified leads, deals and phone sales sent back to ad platforms from your CRM.
Calls attributed to campaigns and keywords with dynamic number insertion.
Lead source and campaign data captured on every form and stored with each contact.
Tags respecting consent choices across all platforms.
No single method tells the whole truth. We combine approaches depending on your data and budget.
| Approach | How it works | Strengths | Limitations |
|---|---|---|---|
| Last click | All credit to the final click before conversion | Simple and easy to understand | Undervalues channels that create demand |
| Data-driven attribution | Algorithmic sharing of credit based on observed paths, as in GA4 and Google Ads | Considers the whole tracked journey | Only sees tracked, consented journeys; limited transparency |
| Platform attribution | Each ad platform's own reporting | Detailed and fast | Overlapping claims; each platform favours itself |
| Self-reported attribution | Asking customers how they heard about you | Captures word of mouth, podcasts and offline influence | Relies on memory; needs careful question design |
| Marketing mix modelling | Statistical models linking spend and outcomes over time | Includes offline media and privacy-safe | Needs longer history and statistical expertise |
| Incrementality tests | Controlled experiments comparing exposed and unexposed groups | The strongest evidence of true impact | Needs enough volume and careful design |
The most important question in marketing measurement is not "which channel was involved?" but "what would have happened without it?" A remarketing campaign may show excellent return because it targets people who were going to buy anyway. A brand awareness campaign may look weak in click reports while actually driving many later sales.
Incrementality testing answers that question with experiments. Examples include geographic tests, where campaigns run in some regions and pause in comparable others; holdout groups, where a share of an audience is deliberately not shown ads; and platform lift studies offered by Meta and Google. Comparing results reveals the additional conversions a channel actually caused.
For larger advertisers, marketing mix modelling uses historical spend and sales data to estimate each channel's contribution, including offline media and effects that tracking can't see. Open-source tools have made this more accessible, though it still needs careful statistical work and enough history to be reliable.
For many businesses, the conversion that matters happens away from the website: a sales call, a site visit, a signed contract or a repeat order. If ad platforms only see form fills, they optimise towards whoever fills in forms, including time-wasters and competitors.
We connect your CRM or sales system back to your ad platforms. Each lead is stored with its click identifiers and campaign data; when it becomes qualified or turns into a sale, that outcome is sent back to Google Ads, Meta or LinkedIn. Bidding then favours the searches, audiences and creative that produce real customers.
This single change often has a bigger effect on lead quality than any campaign optimisation. It also gives you reports that show cost per qualified lead and cost per customer, not just cost per form fill.
Inconsistent campaign tags are one of the most common reasons traffic ends up in the wrong channel. A simple, shared convention fixes most of it. The values below are illustrative.
| Parameter | Convention | Example value |
|---|---|---|
| utm_source | The platform, always lowercase | facebook, google, linkedin, newsletter |
| utm_medium | The type of traffic, from an agreed list | paid_social, cpc, email, referral |
| utm_campaign | Objective, product or offer and date, separated by underscores | leads_seo-audit_2026-10 |
| utm_content | The specific ad or creative variation | video-testimonial_v2 |
| utm_term | Keyword or audience, where useful | b2b-decision-makers |
We document the convention, provide a simple link builder so nobody has to remember the rules, and check reports regularly for stray values. GA4 groups traffic into default channels using source and medium, so values that don't follow its expected patterns can make paid traffic appear as unassigned or referral.

The process of assigning credit for conversions to the marketing touchpoints that influenced them, to understand which channels and campaigns work.
None is perfect. Data-driven attribution is a reasonable default within GA4 and Google Ads, but it should be checked against incrementality tests and self-reported data.
Each platform counts conversions it was involved in using its own rules, including ad views, so the same sale is often claimed by several platforms.
Sending tracking data through a server you control before it reaches analytics and ad platforms, which improves control, data quality and resilience.
A way to send conversion events directly from your server or CRM to an ad platform, alongside or instead of browser-based pixels.
Outcomes that happen outside the website, such as qualified leads, calls or sales, sent back to ad platforms so campaigns optimise towards them.
An experiment that compares people or regions exposed to marketing with similar ones that weren't, to measure the conversions marketing actually caused.
A statistical approach that estimates each channel's contribution to sales from historical data, including offline media, without relying on individual tracking.
It should be, when designed with consent, data minimisation and hashing where required. We implement to your legal advisers' requirements.
Audits take one to two weeks. Implementation depends on platforms and integrations; most projects complete within a few weeks.
Not always. Many businesses get most of the value from clean tracking and CRM integration. A warehouse helps when combining many data sources.
Yes. A simple question on forms or at checkout often reveals influence, like podcasts, word of mouth or social content, that tracking misses.
