Marketing is working when it supplies a steady share of qualified pipeline that turns into new ARR at a cost the business can carry. Our bar is 30% or more of account executive pipeline from marketing, on roughly 20% of total sales and marketing spend. Measure it in three steps: cost per qualified opportunity by channel, conversion of those opportunities through each funnel stage, and marketing cost per dollar of new ARR closed, which should be $0.30 or lower inside a total sales and marketing cost of $1 or less, ideally $0.80 or less. When marketing produces leads but not pipeline, the cause is usually qualification or message rather than volume, because the leads are the wrong profile or sales cannot move them. Start by tagging every opportunity from the last four quarters with its source, then trace each source through to closed ARR.
Judge marketing on qualified pipeline and closed ARR by source, not on activity. If marketing-sourced pipeline is below 30% of AE pipeline, or marketing costs more than $0.30 per $1 of new ARR, or total sales and marketing cost passes $1 per $1 of new ARR, fix qualification and message before adding budget.

Marketing gets measured on what is easy to count. Impressions, clicks, downloads and leads all rise with spend, and none of them says whether a sale happened. The sales funnel play makes the shift explicit: the useful measure is how many prospects moved from unknown to known and on to the next stage, and how quickly. The pipeline creation play then values each stage, so cost per lead becomes cost per closed dollar.
When marketing is not producing pipeline, look at qualification before volume. Loose qualification is the most common sales failure we see across board meetings and founder engagements, and it hides marketing problems as easily as sales ones. The tell is reps saying the product must change to win deals, which usually means the leads were never the right customers. Buyer personas and a written definition of a qualified opportunity fix most of it.
Marketing and sales cost trade against each other. Our view is that marketing should cost $0.30 or less per $1 of new ARR, and the whole acquisition effort $1 or less, ideally $0.80 or less. Where that $1 goes depends on the size of the ACV and how complex the process is to earn the trust that ACV requires: big, high-trust deals lean on enterprise salespeople, smaller ones on marketing.
Channels also move. In 2026 email has degraded, and paid advertising, generative engine optimization and conferences are doing more of the work. A marketing function still measured on last year's channel will look broken when the market moved. Put marketing's pipeline share and cost per qualified opportunity on the KPI dashboard and review them weekly.
The numbers are fictional. A $5M company spends $260K a year on marketing and reports 1,400 leads, up 40%. Tagging the last four quarters by source shows marketing created 22% of AE pipeline, and its opportunities closed at half the rate of referrals. Most marketing leads came from a webinar series that drew consultants and students rather than operators. The team writes a qualified-opportunity definition with sales, cuts the webinars, moves budget to two industry conferences and search content aimed at operators' questions, and reports pipeline and closed ARR by source each week. Two quarters later leads are down by a third and marketing's pipeline share is 31%.
In long enterprise cycles, marketing's effect on closed ARR lags pipeline, so read pipeline created and stage conversion first and closed ARR later. Conference and content spend usually needs about one quarter to show in pipeline; agree that window before spending and judge it then. The marketing share of the $1 total also moves with the deal: larger ACVs and a longer process to earn the buyer's trust put more of the cost in enterprise salespeople and less in marketing.
From the Golden Section mistakes list, each paired with the play that prevents it.
Measuring cost per lead or impressions rather than cost per closed ARR rewards the wrong marketing.
Unqualified opportunities make marketing look productive and sales look broken at the same time.
Unclear messaging produces traffic without pipeline, because the right buyers do not recognize themselves.
Brand spend that outruns financial results consumes budget that measured channels could have used.

Usually because the leads are the wrong profile, the message does not match the buyer's problem, or sales and marketing define a qualified opportunity differently. Less often, the channel itself has stopped working, as email has for many companies in 2026. Trace leads through each funnel stage to see where they die before buying more.
Our preferred measure is marketing cost per $1 of new ARR, by channel: $0.30 or lower, inside a total sales and marketing cost of $1 or less per $1 of new ARR, ideally $0.80 or less. Track cost per qualified opportunity and close rate beneath it, and compare with the lifetime gross profit of the customers each channel brings in. Activity metrics belong on a working dashboard, not in the ROI calculation.
Set the window in advance. Four to six weeks or a fixed number of contacts works for direct-response channels; conferences and content usually need about one quarter before pipeline and closed revenue can be judged. Write the floor and the review date before you spend.
A marketing channel that reliably produces pipeline at a CAC payback under 18 months can be scaled with non-dilutive debt. Until you can show that by source, the right investment is measurement rather than capital.
