LinkedIn Marketing Attribution Case Study

Executive summary

This case study tracks a Q3–Q4 2025 LinkedIn-plus-exhibition campaign by an Indian industrial sensor manufacturer. LinkedIn ads delivered 240,000 impressions to a targeted procurement-manager audience across Pune, Mumbai, Bengaluru and Chennai. The same campaign's exhibition presence at Automation Expo Mumbai produced 180 scanned cards. Closed-loop attribution showed that 14 of the 180 booth visitors had seen the LinkedIn ad in the preceding 60 days. Of those 14, four advanced to RFQ and two closed in Q1 2026. The marketing-attribution synthesis demonstrates that channel attribution is solvable once card scans carry source provenance into revenue attribution.

Methodology and observations

The LinkedIn campaign was tagged with UTM parameters; landing-page conversions and booth-scan records both routed into the same VynDeal instance. Identity matching between the LinkedIn clicker and the booth scanner used email-address overlap. The attribution workflow required no manual data joining; identity resolution happened at scan ingestion. The LinkedIn-to-PO maths becomes mechanical once the tags are preserved end to end — the same principle that closes the marketing-sales gap.

"Marketing said the campaign worked. Sales said the booth worked. The scan tag proved they both did — on the same two deals." — Field note, Quiamo attribution desk

Frequently asked

How do you attribute B2B revenue across LinkedIn and exhibition channels?

Tag every touchpoint with consistent source IDs: UTM parameters for digital ads, scan-source tags for exhibition cards. Match identities by email at the CRM layer. The closed-loop attribution then runs as a database join: deal-revenue by source-tag-set, returning channel attribution.

What does multi-touch attribution mean for B2B manufacturing?

It means recognising that most B2B deals have multiple touchpoints before close — a LinkedIn ad impression, an exhibition booth visit, a content download, a sales call. Multi-touch attribution preserves all four touches on the closed deal so each channel gets credit proportional to its actual contribution.
