Marketing channel attribution connects every touchpoint an account had to the deals that account opens and closes. The touchpoints come from channels such as LinkedIn ads, Google ads, organic visits, direct traffic, and AI referrals. It shows how each channel contributed, instead of crediting only one click.
How marketing channel attribution works
In B2B, buyers rarely convert on the first visit. Channel attribution works in four steps:
- Collect the touchpoints each channel produced and match them to the company behind them.
- Put all touchpoints on one account timeline.
- Join the timeline to the deals in your CRM.
- Count a channel as influencing a deal when the account reached a minimum number of impressions inside a set window before the deal opened. You choose both numbers, so report them next to the result. I explain this in our post on influenced pipeline.

This is different from last-touch attribution, which gives all the credit to the final touchpoint, so direct traffic and branded search often win the credit for work other channels started. Treat the result as an explanation, not proof. Your CRM records what happened, and the account journey helps you explain how each channel contributed. To test whether a channel truly causes deals, compare target accounts with a control group that sees no ads.
Where you see marketing channel attribution
You can see it in your CRM (HubSpot, Salesforce or Attio) as source fields on contacts, companies, and deals. In HubSpot, a contact's source history shows the channel of each touch. LinkedIn Campaign Manager adds its own view, with Last Touch - Last Campaign and Last Touch - Each Campaign attribution settings. Each shows only one platform's version of the story.
ZenABM shows which companies engage with your LinkedIn ads, using LinkedIn's official API and no form fills. It also puts Google Ads, Reddit Ads, AI referrals, and organic visits on the same company journey, so you can see which channels touched a deal.
