The Attribution Gap 2026
Across 214 accounts' closed-won deals, 52% of won revenue had no reliable source. The stack captured a median of 6 touchpoints on journeys that actually took ~27. When tools don't share data, most of what marketing earns can't be traced back to what marketing did.

Marketers are confident. The data underneath them is not.
Between January and June 2026 we reconciled the closed-won deals of 214 B2B accounts on Landing Platform against the source data their stack had captured — first touch, channel, campaign — to see how much of won revenue could actually be traced back to a marketing action.
Just under half could. 52% of won revenue carried no reliable source — the deal closed, but why it closed was a guess. That squares with the wider picture: 84% of marketers say they're confident in their ROI measurement, yet only 38% actually measure it holistically across channels.1 Confidence is high; capability isn't.
The cause is structural. When the ad platforms, the site analytics, the CRM and the email tool each hold a slice of the journey and never reconcile it, the full path is never assembled. The stack doesn't lie — it just can't see. And you can't optimise what you can't attribute.
Figures are from Landing Platform's own account base; full limitations below. Independent research is cited inline wherever it measures the same thing.
Sure it works. Can't prove how.
There's a wide gap between believing marketing drives revenue and being able to show it. Nearly everyone believes; far fewer can demonstrate; fewer still measure it properly end-to-end.
The buyer takes 27 steps. The stack sees 6.
Modern B2B buying is long, non-linear and mostly anonymous. Forrester puts the average at 27 interactions before a decision — up from 17 in 2019.6 Gartner finds buyers spend just 17% of the journey with any supplier.5 In our data, the median stack recorded only 6 of those touchpoints.
What you can't measure, you overspend on
The attribution gap isn't just a reporting inconvenience — it's a budget leak. When you can't tell which channels produced revenue, spend keeps flowing to the ones that merely produced clicks. In our data, a median 24% of spend went to channels that couldn't be tied to any won revenue.
One shared journey, not four half-journeys
Attribution isn't a model you buy — it's a data problem you close. When the ad clicks, site sessions, form fills, CRM deals and email opens for a contact all resolve to one timeline, the path assembles itself. In accounts that moved capture and CRM onto one system, traceable revenue roughly doubled.
“Most teams aren't wrong about marketing working — they're just unable to prove which part. When half your won revenue has no traceable source, every budget decision is a coin toss dressed up as a dashboard. Close the data gap and the story was in there the whole time.

What this study is — and what it isn't
The boundaries, plainly.
- It is our own account base. 214 B2B accounts on Landing Platform — not a random industry sample. B2B, multi-touch journeys; B2C and pure e-commerce attribution behaves differently.
- "Attributable" means traceable to a captured source, not causal. We measured whether a won deal could be tied to a recorded first/last touch — not a controlled proof that the touch caused the sale.
- The 27-touchpoint figure is Forrester's, not ours. We compared our captured-touchpoint median against Forrester's published journey length; different studies count touchpoints differently.
- The +36 points is for accounts that consolidated capture and CRM. It reflects teams that unified tracking, not every account that switched.
- Some sources flagged. Where a figure is a vendor benchmark (e.g. journey-length estimates) rather than peer-reviewed, it is attributed as such below.

How much marketing revenue goes unattributed?
In this analysis of 214 B2B accounts, 52% of closed-won revenue had no reliable source. Industry-wide, 84% of marketers feel confident in their measurement but only 38% actually measure ROI holistically across channels.1
Why is B2B attribution so hard?
The journey is long and mostly anonymous: buyers take around 27 interactions before deciding and spend just 17% of the journey with suppliers.56 When each tool captures only its slice and they never reconcile, the full path — especially the first touch — is never assembled.
What does poor attribution actually cost?
Budget. When you can't tell which channels drove revenue, spend flows to the ones that drove clicks. A median 24% of spend in this study couldn't be tied to won revenue; industry-wide, marketers waste around 26% of budgets on ineffective channels.9
Do more attribution tools fix it?
Rarely — they add another data island. The average marketer already pulls from 15 data sources.7 Attribution is a data-unification problem: it improves when touchpoints and deals share one timeline, not when you bolt on another model.
Can you ever attribute 100% of revenue?
No — dark social, word of mouth and offline touches stay fuzzy for everyone. The realistic goal is going from "guessing on half" to tracing most of it. In our data, unifying capture and CRM took traceable revenue from ~48% to ~84% — enough to reallocate budget with confidence.

Trace most of your revenue — on one shared timeline
Landing Platform captures ad clicks, sessions, forms, deals and email against one contact record, so attribution assembles itself instead of scattering across four tools. Founding cohort: flat pricing, unlimited seats, locked two years.
