Ask a few B2B marketing teams what their demand generation programme involves and the answers tend to sound alike. Gated ebooks, paid lead forms on LinkedIn, a webinar or two, and a Monday report counting MQLs. Ask the sales team about the same programme and you'll hear that they stopped opening those leads some time ago.
Most teams react by tightening the lead scoring or changing the content offer. That treats it as a quality problem when the cause is timing. Most of the people filling in those forms aren't buying anything this quarter, and a programme built on forms can only measure the ones who are. The test is simple: switch the forms off for a month and look at what's still working.
How did gated content become "demand gen"?
It happened because forms are easy to count. A gated ebook produces a name, a name becomes an MQL, and an MQL fits neatly in a weekly report and a cost-per-lead figure. Over time the label drifted to cover anything marketing produced that ended in a form, even though the activity itself is lead capture.
Our guide to demand generation versus lead generation covers the textbook difference: demand gen builds awareness and trust over months, while lead gen turns interest into meetings now. Most teams know the definitions. The drift happens in the measurement. Once a programme is judged on form fills, every piece of content gets pushed towards a form, and the work that reaches buyers who aren't ready yet starts to look like it produces nothing.
The 95-5 maths behind a form-fill number
The 95-5 rule, developed by the LinkedIn B2B Institute with Professor John Dawes of the Ehrenberg-Bass Institute, estimates that about 95% of your potential buyers are out of market at any given time. It's built on how rarely companies switch suppliers. In their research with Ehrenberg-Bass, 80% of companies changed banking services about once every five years. It's a model rather than a survey, so treat 5% as an order of magnitude. The order of magnitude is enough to change how you read a lead report.
The 6sense numbers show why staying in front of them pays. In 6sense's 2025 Buyer Experience Report, the winning vendor was on the buyer's day-one shortlist 95% of the time. The same study found that 94% of buyers ranked their shortlist before contacting any vendor, first contact came 61% of the way through the process, and buyers went on to purchase from their top-ranked vendor 77% of the time (CustomerThink's write-up of the report, listed in the sources, has the detail).
How to run the forms test
Pick a month and treat it as an experiment, agreed with sales and finance beforehand so nobody panics when the MQL line drops.
- Choose a normal month. Avoid launches, your biggest event and the end of the financial year.
- Ungate your three most downloaded assets and pause paid lead-form campaigns. Keep the budget, and spend it on promoting the same content without a form.
- Keep a form where someone is asking for a conversation. Demo requests, pricing enquiries and contact forms stay on. You're testing the forms that collect readers.
- Keep publishing at your usual pace, including founder and team posts on LinkedIn.
- Record five signals each week: target accounts visiting the site, replies to outbound from accounts that have engaged with your content, inbound enquiries and demo requests, what those enquiries say when asked how they found you, and meetings and pipeline created.
- Compare with the same five signals for the previous month, with the forms still on.
What the result tells you
Read the result against your pipeline rather than your lead count. The table below covers the patterns you're most likely to see.
| What happens with the forms off | What it means |
|---|---|
| Pipeline and inbound enquiries hold steady; MQLs fall | The MQLs weren't driving pipeline. The demand work is happening somewhere else, often in founder posts or word of mouth |
| Replies from engaged accounts stay well above replies from cold ones | Your content is warming the market. Point outbound at the accounts it reaches |
| Enquiries start naming a post, a guide or a person | Ungated content is building recognition. Keep it ungated |
| Everything drops, pipeline included | Forms were the whole programme. You were running lead generation, and the demand work still needs building |
The last row is the one people dread, and it's useful to know. It means the budget has been buying lead capture, so the decision ahead is a clean one: keep some of it as honest lead gen, and start a separate effort aimed at the 95.
What demand gen looks like when it works
It keeps working with no form attached. Four checks will tell you whether a programme is doing that:
- It works without a form. People read, watch and share it, and you can see that in engagement from target accounts rather than in downloads.
- Sales can see which accounts are warming. Engagement is reported by account, so an SDR knows which companies have seen your content before they reach out.
- It's judged on replies and meetings from those accounts. The comparison that matters is warmed accounts against cold ones.
- It keeps running in the quiet months. The 95 don't stop existing when the quarter's campaign ends.
The third check is where demand gen and lead gen meet, and it's why we run them in sequence. Outreach to an account that has seen your content for months gets a different reply from outreach to one that has never heard of you. With Descartes, demand generation ran alongside lead generation from the beginning, so by the time an SDR made contact, the prospect had already seen the name. That programme produced £5M+ pipeline in the first six months, from 120+ qualified meetings.
For the measurement side in more depth, our piece on demand generation ROI covers which metrics to report upwards. If you want to see how we run the two together, the Demand Generation service page sets it out.
Where a form still belongs
Some forms deserve to stay. A pricing calculator or a template someone needs for a meeting tomorrow attracts people who are closer to a decision. Gating those is honest lead generation, and you should call it that and judge it on meetings.
The test also matters less in some markets. If you sell to a few hundred named accounts and your team already knows most of the buyers, account-based outreach and events may do more than any content programme. And if you need pipeline in the next 30 days, start with outbound. Demand gen takes quarters to pay back, so it should run alongside lead generation from the start, sized so the slower work isn't starved while you wait.
The LinkedIn B2B Institute makes the same split in its own 95-5 write-up: invest in lead generation for the 5% who are in market, and invest "far more heavily" in reaching the rest of the category. We sell both, which you should factor in. The forms test costs nothing, and a month of it will tell you more about your programme than another quarter of MQL reports.
Frequently asked questions
Is gated content ever demand generation?
Rarely. Putting a form in front of a guide turns it into a lead capture tool, because the reader pays with their details and gets a follow-up call. That's a perfectly good lead gen tactic for assets people need right now, like templates or calculators. For ideas you want lots of future buyers to absorb, ungated reach usually does more.
Won't switching off forms make our numbers look terrible?
The MQL line will drop, which is the point of the test. Agree in advance with sales and finance that you're running an experiment for one month, and report the signals listed in the test alongside it. If pipeline holds while MQLs fall, you've learned the MQLs weren't driving it. If pipeline falls too, you've learned that as well.
How long does demand generation take to show up in pipeline?
Longer than a quarter on its own, which is why it pairs well with outbound. Leading signals such as replies from warmed accounts and inbound enquiries that name your content usually move first. Run lead generation alongside it so pipeline isn't waiting on the slow part, and judge demand gen on how those outbound conversations change.
What should we report instead of MQLs?
Report what happens in your target accounts: how many are engaging with your content, reply rates to outreach from engaged accounts compared with cold ones, meetings and pipeline from those accounts, and how many inbound enquiries mention something you published. These take a little more work to pull together, and sales will recognise every one of them.
