Linear attribution vs B2B attribution

Linear attribution splits credit evenly across every tracked touch on the way to a deal. B2B attribution keeps Visit, Pages, Meeting, and Deal on one path so CAC and channel quality stay honest. That is the real split when teams ask about linear attribution vs B2B attribution.
Equal credit feels fair on a spreadsheet. It still answers a different question than revenue path. A 25% slice on each touch does not tell you whether the Meeting was on the path, whether a later Direct or LLM return mattered, or which spend closed revenue.
We already covered first-touch attribution vs B2B attribution and multi-touch vs single-touch attribution. Linear sits inside the multi-touch family: every touch gets the same weight. B2B attribution still has to keep the path intact.
What does linear attribution actually credit?
Linear attribution takes the tracked touches in a lookback window and divides credit equally. Four touches means 25% each. Ten touches means 10% each. Tools in analytics and CRM stacks, including reports teams run in HubSpot, often expose linear as a default multi-touch option next to first-touch and last-click.
The model is easy to explain. Every interaction that made the list gets a share. The model still depends on which events entered the list. If offline Meetings, calendar bookers, or later Direct and LLM Visits never join the touch table, they get 0% even though linear claims to be fair.
So a linear report can look balanced while the path that closed the deal is still incomplete.

What does B2B attribution have to keep on the path?
B2B attribution has to keep the journey together. A Visit lands from ads, search, a partner, or elsewhere. Pages get read. A Meeting gets booked. A Deal moves in the CRM. Later returns can show up as Direct or as traffic from ChatGPT, Claude, Perplexity, or Gemini.
Equal math can sit on top of that path when you want a multi-touch view. It cannot replace the path. Multi-touch without Visit to Pages to Meeting to Deal still collapses into campaign touch lists. Real CAC needs the Meetings and Deals on the same ledger as the Visits.
Source is built around that path with one pixel and GTM, no warehouse required: Visit to Pages to Meeting to Deal in one place, with chat over the data and daily Slack reports when you want them.

When does linear attribution mislead CAC and channel quality?
Linear misleads when the touch list is padded with low-intent noise or missing high-intent steps. A cheap content click and a hard-won demo can get the same 25%. Channel quality then drifts toward volume of touches, not contribution to Meetings and Deals.
It also misleads when paid platforms report their own conversions while your linear model only sees site clicks. The ad platform and the linear report can both look consistent and still disagree with closed revenue. Teams then argue about model choice instead of path completeness.
B2B cycles make this worse. Long sales paths accumulate many touches. Equal credit dilutes the steps that actually opened pipeline. LLM and Direct returns get undercounted when they never enter the touch table cleanly.
How should teams use linear without treating it as the revenue ledger?
Keep linear as a diagnostic multi-touch view. It is useful for asking which mix of touches showed up before a deal. It is a weak sole answer for which spend drove closed revenue.
Pair it with path-level B2B attribution. Compare equal credit against the full Visit to Pages to Meeting to Deal chain. Watch for Assisted steps, offline Meetings, and later Direct or LLM Visits. That is how you keep CAC honest without throwing away linear insight.

Equal credit is still useful when you want a simple multi-touch view of the mix that showed up. Just do not confuse a balanced pie chart with a complete Visit to Pages to Meeting to Deal ledger. Path completeness decides whether CAC and channel quality can be trusted.
FAQ
Is linear attribution wrong?
No. It is an equal-weight multi-touch model. It becomes wrong when teams use it as the only revenue ledger.
Is linear the same as multi-touch?
Linear is one multi-touch rule. Multi-touch also includes position-based, time-decay attribution vs B2B attribution, and other weightings. B2B attribution still needs the full path underneath any weighting.
Does B2B attribution replace linear reports?
No. Keep linear for equal-credit diagnostics. Use B2B attribution for path-to-revenue and CAC questions.
