Here is a scene I have watched play out more times than I want to admit across a thousand-plus enterprise webinars: a session pulls 400 registrants, 170 show up live, and the next morning marketing dumps all 400 into the CRM tagged “webinar lead.” Sales burns through the list in two days, gets voicemail after voicemail from people who never attended, and quietly stops trusting anything with the word webinar on it. The event did its job — the scoring destroyed the evidence.
The fix is not more lead-scoring theory. It is a short list of actual numbers you can type into HubSpot or Marketo this afternoon — point values for attendance, engagement, and replay views, plus a defensible MQL threshold. That is what this playbook gives you.
Why registrants and attendees can’t score the same
The single most common mistake in webinar lead scoring is treating registration and attendance as the same signal. They are not close. A registration is thirty seconds of topic interest. Attendance is 45 minutes of voluntary attention from someone with a calendar full of alternatives. In our programs, registration-to-live attendance lands between 35–50% — colder audiences run 25–35% — which means half or more of your “webinar leads” never heard a word you said. Full numbers are in our webinar conversion rate benchmarks.
If both actions earn 20 points, sales cannot tell the difference between a genuine prospect and someone who liked your email subject line. Score registration low — 5 points — and treat it as topic intent, not buying intent. The registered-versus-attended split is the most predictive line in the entire model. Everything else is refinement.
The point values
These are the values I start every scoring build with. They assume a roughly 100-point scale where MQL sits somewhere in the 60–75 band — more on the threshold below.
| Action | Points | Notes |
|---|---|---|
| Registered | +5 | Topic intent only — never enough to route to sales |
| Attended live | +15 | The base attendance credit, any duration |
| Stayed 75%+ of the session | +10 | Stacks with the base credit |
| Answered a poll | +5 | Cap at two polls per session |
| Asked a Q&A question | +10 to +15 | Top end if the question names their own use case |
| Clicked the in-session CTA | +15 to +20 | Demo request or meeting booked = top end |
| Watched 50%+ of the replay | +15 | Attendance equivalent — see below |
| Opened replay, watched under 25% | +5 | A click, not a viewing |
| Registered, never attended or watched | +0 further | Keeps the 5 registration points, nothing more |
Notice what this produces: attendance alone is worth 15–25 points depending on how long they stayed. That is deliberate. Showing up is meaningful, but on its own it should never trip an MQL threshold — plenty of attendees are students, competitors, and the pleasantly curious.
How engagement stacks to 40–60 points
The model earns its keep when actions stack. Take a realistic engaged attendee: attended live (+15), stayed most of the session (+10), answered a poll (+5), asked a question about their own environment (+12), clicked the CTA to book time (+18). That is 60 points from one event — and every one of those signals was voluntary. A quieter but real prospect might land at 40–45. Both are worth a human’s attention. The attendee who logged in, went on mute in another tab, and left at minute 20 sits at 15 — and that is exactly where they belong.
One honest caveat: you cannot score engagement you never designed. If your session has no polls, no CTA moment, and a Q&A that gets 90 seconds at the end, everyone flatlines at the attendance score and the model tells you nothing. Build the scoring moments into the run of show first — our webinar engagement tactics playbook covers how.
Scoring replay viewers
Replay viewers are the most under-scored audience in B2B. Across our programs the replay audience typically equals the live audience or beats it — and a replay viewer who watched half the session chose to spend 20-plus minutes with your content on their own time. No live-event social pressure, no calendar block they felt obligated to honor. That is arguably a cleaner intent signal than live attendance.
The rule I use: 50% watched equals attendance, worth the same +15. Under 25% watched is a click, worth +5. Between the two, use judgment or split the difference at +10. The practical requirement is that your platform reports watch percentage, not just replay-page visits — most decent platforms do, but the data rarely flows into your CRM automatically. Pull it weekly and batch-update. How you deliver that replay — and when — is a follow-up problem, covered in the webinar follow-up playbook.
Setting the MQL threshold
Across the scoring models I have helped teams run, the MQL threshold that holds up sits between 60 and 75 points. Sanity-check yours against three cases. A registrant who never shows (5 points) should be nowhere near it. An attendee who did nothing else (15–25) should not cross on one event — but should cross after attending two or three sessions with light engagement, which is exactly the multi-touch behavior that predicts pipeline. And a single-event attendee who asked a question and clicked the CTA (55–60) should be right at the line or over it.
Tune it with sales feedback, not marketing hope. If reps say webinar MQLs feel cold, raise the line to 75 before you touch the point values. If pipeline is starving, resist dropping below 55 — the fix is almost always more engagement design, not a cheaper threshold. And when a lead does cross, what sales receives matters as much as the score itself; the webinar sales handoff playbook covers what to pass along with the number.
Score decay and negative points
Webinar intent has a shelf life. Someone who hit 60 points in March is not a hot lead in July. Halve webinar-sourced points after 60–90 days, or use your platform’s time-based decay if it has one. Two lines of negative scoring are worth adding: personal or student email domains (−10) and known competitor domains (−100, effectively a block). Beyond that, keep the model small. Every scoring build I have seen fail failed by growing past what anyone could explain — if you cannot fit the whole model on one screen, sales will not trust it and you will not maintain it. Aim for a dozen rules or fewer.
Putting it into HubSpot or Marketo
Implementation is mostly plumbing. You need five fields per contact per event: registered, attended live, percent watched (live or replay), engagement actions (polls, Q&A, CTA click), and event date. Zoom, ON24, Goldcast, and Teams all capture these; the catch is that most native CRM integrations sync registered and attended but drop the engagement depth. Check what actually arrives before you build rules against fields that will sit empty — you may need the platform’s engagement export on a weekly cadence.
In HubSpot, build the point values as positive attributes on a custom score property, one attribute per row of the table above. In Marketo, each action becomes a smart campaign with a score-token change (+15, +10, and so on) so the values stay editable in one place. Either way, run the model silently for two or three events first, compare who crossed the threshold against who sales would actually want, and adjust. The numbers above are a starting position with a lot of reps behind it — your audience will tell you where to bend them.
Frequently asked questions
How many points should webinar attendance be worth?
In a 100-point model with an MQL threshold of 60–75, live attendance is worth 15–25 points: 15 as a base credit plus 10 for staying through 75% or more of the session. That keeps attendance meaningful without letting a single show-up trip the threshold on its own.
What is a good MQL threshold for webinar leads?
Most models that survive contact with a sales team set MQL between 60 and 75 points. One highly engaged webinar can get a lead there; passive attendance alone cannot. If sales reports cold handoffs, raise the threshold before changing point values.
Should you score webinar registrants who don’t attend?
Yes, but lightly — 5 points. A no-show registration is a topic-interest signal that should influence nurture content, not sales routing. The common failure mode is scoring registrants and attendees identically, which floods sales with people who never saw the session.
Do replay viewers count as attendees for lead scoring?
If they watched at least 50% of the replay, score them as attendees — the same +15. Someone who opened the replay and left inside a few minutes gets +5. You need watch-percentage data from your webinar platform to make this distinction, and it is worth the plumbing.
