"Views" is not an ROI metric. "Engagement rate" isn't either. Video ROI is knowable, but only if you measure what actually correlates with revenue — and stop measuring what just makes the dashboard look busy.
The three real questions
Everything worth measuring answers one of these:
- Did this video move someone toward a purchase who wasn't already moving?
- Did it shorten the path for someone who was?
- Did it keep bringing new people in over time?
If a metric can't answer one of these, delete it from your reporting.
Metric 1: retention curve shape
Not average view duration — the shape of the retention curve. What you want:
- Sharp drop in the first 5 seconds (normal, unavoidable).
- Then a nearly flat line for the rest of the video.
- Small bumps upward at replay points — a sign of memorable moments.
Curves that keep dropping mean your script has slow spots. Fix the script; don't fix the metric.
Metric 2: assisted conversions
In your analytics, look at conversions where a video page or YouTube visit appears anywhere in the path — not just as the last click. For most B2B and considered purchases, video shows up in the middle of the journey and gets zero credit under last-click attribution. Switch to data-driven or position-based attribution and video typically doubles or triples in measured contribution.
Metric 3: branded search lift
In the 30 days after a video ships, check Google Search Console for branded queries ("[your company]", "[your company] pricing", "[your company] reviews"). A well-made video reliably produces a 10–40% lift. If you see zero movement across three consecutive videos, the videos aren't reaching new people.
Metric 4: sales-cycle length for video-touched leads
Tag leads in your CRM who visited a video page or watched more than 50% of a YouTube video. Compare their average time-to-close against untouched leads. In most B2B pipelines video-touched leads close 20–40% faster and at higher ACV. That number is the honest ROI story.
Metric 5: content decay rate
For each evergreen video, measure views in month 1, month 6, and month 12. Videos that keep 60%+ of month-1 traffic at month 12 are your library. Videos that decay to under 20% are ads with a longer shelf life. Both are fine — but you should know which is which before you commission the next one.
The reporting template
A useful video-ROI report has five rows and no more: retention shape, assisted conversions, branded-search delta, video-touched close rate, and cost-per-evergreen-view. Anything beyond that is decoration.
The honest caveat
No attribution model captures brand lift perfectly. If a video makes a buyer trust you enough to type your name into Google six months later, no tool will connect those dots cleanly. Track what you can, spend where the math works, and accept that some of video's value shows up as a business that's simply easier to run.
