Bizible attribution models made position-based attribution familiar to B2B marketers: give the most credit to the touches at key milestones, such as the first touch, the moment someone became a lead and the moment an opportunity opened. This article does not describe that product. It answers a practical question instead: can a 10 to 250 person firm get the benefit of milestone-based attribution on the levelpartner.ai platform, without an enterprise attribution tool, and what do you give up?
The milestone idea in plain terms
Position-based models assume that some moments in a buying journey matter more than others. The common shapes are these. A U-shaped model splits most credit between the first touch and the touch that turned someone into a lead. A W-shaped model adds a third milestone, the touch that preceded opportunity creation. A full-path model adds the touch before the deal closed. Touches in between share whatever credit is left.
The appeal is obvious. It rewards the channels that start conversations and the ones that move them forward, without pretending every newsletter open mattered equally.
What you need to record
Milestone models rely on knowing which touch happened at each milestone. On the platform, the first touch is recorded on the contact when they arrive. The lead-creation touch is the attribution at the form, booking or chat that created them. The opportunity touch is the latest attribution when the opportunity opens. Capture that third one deliberately, because it is not stored by default in a separate field.
Before you start
- Contact attribution populating from platform forms, calendars and chat.
- Campaign parameters on every marketing link.
- An opportunity pipeline used consistently by the sales team.
- A rule that every new opportunity gets a source, set from the touch that created the lead.
Building a milestone model on the platform
- Agree in writing which touches count as first, lead and opportunity milestones.
- Go to Dashboard, open your dashboard and click Edit Dashboard.
- Click + Add Widget and add Won Opportunity Value.
- In Conditions, click Add Filter, select Attribution and choose First Attribution.
- Set Group By to Session Source, then click Save.
- Add a second copy of the widget using Latest Attribution.
- When each opportunity opens, set its source to the lead-creation touch.
- Add the Lead Source Report to show won value by that source.
- Click Save Changes so managers see all three views.
- Each quarter, click each widget, use Export and apply your weights.
The trade-off of doing it this way
A dedicated attribution product tracks every touch, assigns fractional credit automatically and reports it continuously. The approach above captures three milestones and leaves the final weighting to a quarterly spreadsheet. You give up automatic fractional credit and mid-quarter visibility of the blended figure. You keep three clear, checkable views that any manager can trace back to a real record. For firms closing a few hundred deals a year, that clarity is often worth more than precision.
For a simpler equal split, see the linear attribution model.
Take a £90,000 contract, an illustrative value, with a first touch from organic search, a lead touch from a webinar registration and an opportunity touch from a case study email. With a split of 30 for each milestone and 10 shared across two middle touches, organic search, the webinar and email would each receive £27,000, and the two middle touches £4,500 each. On last touch alone, email would take all £90,000.
What most milestone articles get wrong
They present the weights as if they were measured. They are not. Thirty, thirty and thirty is a judgement, and so is any other split. Choose weights that reflect what your sales team believes matters, write down why, and keep them stable. The value of the model comes from comparing quarters with the same rules, not from the weights being correct.
Weekly time
The workflow runs without attention. Each quarter, allow two hours to export, apply the weights and present the result. Check monthly that new opportunities are getting all three milestone fields filled.
Firms change the weights each quarter to make a favoured channel look better. Trend lines become meaningless and leadership stops trusting the model. Set the weights once a year at most.
When not to use it
If your sales cycle is short and most people enquire and buy within days, the three milestones collapse into one touch and the model adds nothing. Use last touch. And if you have no consistent opportunity stage, fix the pipeline before attempting milestone attribution.
Troubleshooting
The opportunity touch is always the same as the lead touch. People are not returning between enquiry and opportunity, or return visits are not tracked. Check that the tracking code covers your whole site and that email links carry campaign parameters.
Many opportunities lack a first touch. They came from imported contacts. Label imported contacts with a known source so they are excluded rather than counted as missing.
Sales creates opportunities before marketing touches are recorded. Ask sales to log prospects as contacts first, so the contact carries its attribution before a deal is opened.
Frequently asked questions
Do I need Bizible or a similar tool for position-based attribution?
Not at this size. Recording milestone touches on the opportunity and weighting them quarterly delivers most of the insight. A dedicated tool becomes worthwhile when volumes and channel counts make manual weighting slow.
Which shape suits a long B2B sales cycle?
W-shaped, because opportunity creation is a meaningful milestone in a long cycle. Read B2B marketing attribution for how to report it.
Can I see each milestone separately?
Yes. The three views can each be read as their own ranking, which is often more useful than the blended figure. See also choosing a marketing attribution model.
