Every lead, traced to source
Rebuilding click-to-CRM attribution for a multi-brand, multi-domain language services group, so every enquiry reaches the CRM carrying its full marketing journey.
Speak with NicInternational Language Services Group
Client name and identifying details withheld for confidentiality.
The problem on the table.
Attribution across a multi-brand, multi-domain group is fragile by default. Click IDs drop off the URL the moment a visitor navigates, consent configured for compliance alone can quietly break measurement, and internal hops between a group's own sites get logged as fresh external referrals.
Left unaddressed, that leaves enquiries reaching the CRM with no reliable source, and media decisions resting on numbers the business cannot fully stand behind. Good media is only as honest as the data beneath it, and at this scale the data can leak at every join.
What forensic looked like here.
A single, resilient attribution layer was built to run across the whole estate. It captures every major click ID, the UTMs and the platform cookies into durable storage, derives first touch, last touch and channel, and injects them as hidden fields into on-page forms and across the iframe boundary into the group's Zoho CRM and HubSpot forms.
Consent Mode v2 and server-side tracking were implemented so measurement and data protection reinforce each other rather than fight. Click-ID recovery was hardened for platforms with no URL passthrough, Enhanced Conversions were hashed in the browser, analytics join keys were scoped to the property that owns them, and the self-referral and cross-domain group hops were corrected so sister-site traffic is no longer mistaken for new acquisition.
- Durable capture of click IDs, UTMs and platform cookies
- First-touch, last-touch and channel derivation
- Hidden-field injection into on-page and iframe CRM forms
- Consent Mode v2 with server-side tracking
- Enhanced Conversions with in-browser hashing
- Cross-domain and self-referral correction across the group
What changed.
Every enquiry now reaches the CRM carrying its full first-touch and last-touch journey, channel and click IDs, so spend can finally be judged against the pipeline it actually creates rather than a misleading last-click guess.
The data layer is consent-safe, resilient to navigation and back-forward cache, and built to survive the loss of third-party cookies. Across the estate, marketing decisions now rest on numbers the business can trust.

Other engagements.
Your number is next.
A proper conversation with the person who would do the work. Tell me where you are and what you are weighing up, and you will get an honest, forensic read on what I would change, what I would leave alone, and where the real upside is.
Speak with NicThe senior read,
once a week.
Most marketing newsletters are noise on a schedule. This is not that. Once a week I send a short, considered read on the shifts that actually change what you should do, in paid media, AI search and technical SEO. Filtered, weighted and signed off by me before it goes out. The judgement is mine.
