How long is a B2B buying cycle now?

6sense's 2025 Buyer Experience Report puts the average at 10.1 months, down from 11.3, with buying groups of roughly ten or more people and first contact with a seller at about 61% of the journey.

Does being contacted first actually matter?

Heavily. 6sense reports the vendor contacted first wins eight out of ten deals. Among buyers with no pre-existing ranking, first contact won only 57% of the time, which means rank precedes persuasion.

What is the 95-5 rule?

Professor John Dawes at the Ehrenberg-Bass Institute observed that up to 95% of business buyers are not actively purchasing at any moment, so advertising mainly works by building and refreshing memory links to the brand.

How do you measure dark social in B2B?

Add a self-reported attribution field to your demo form and compare it with your analytics. The gap between the two is your dark funnel. For a ten-month, ten-person purchase it beats a last-click model.

What does a B2B lead cost in paid search?

WordStream's 2026 benchmark puts business services at $5.87 per click, a 4.85% conversion rate and $93.69 per lead. That is well below the 8.18% median conversion rate and 40% above the median lead cost.

Short answerB2B marketing works when it accepts that most of the buying happens where you cannot see it. Buying groups run past ten people, cycles average 10.1 months, and buyers first contact a seller about 61% of the way through. The vendor contacted first wins eight of ten deals.

The short answer

B2B marketing works when it accepts that most of the buying happens where you cannot see it. Buying groups run past ten people, cycles average 10.1 months, and buyers first contact a seller about 61% of the way through. The vendor contacted first wins eight of ten deals.

What actually drives the number

The shortlist forms before you exist in the CRM. 6sense’s 2025 B2B Buyer Experience Report, built on nearly 4,000 respondents, found the point of first contact has moved to roughly 61% of the buying journey, down from 69%, with buying groups of about ten or more people, cycles averaging 10.1 months, and 5.1 vendors considered against a Day One shortlist of 3.6. The report also finds the vendor contacted first continues to win eight out of ten deals, and among buyers with no pre-existing ranking, first contact won only 57% of the time. Rank precedes persuasion. Whatever put you on the Day One shortlist happened months before any form fill, and it was almost certainly not measured.

Almost nobody is in the market right now. Professor John Dawes at the Ehrenberg-Bass Institute set out the 95-5 rule: up to 95% of business buyers are not actively purchasing at any given moment, so advertising mainly works by building and refreshing memory links to the brand. The implication is uncomfortable for a pipeline-driven organisation. If you only advertise to the 5% who are shopping, you are competing on price against everyone else doing the same thing, and you are absent from the memory of the 95% who will form the next shortlist.

Buyers want to be left alone until they do not. Gartner reports that 75% of B2B buyers prefer a rep-free experience, but self-service digital purchases are far more likely to end in purchase regret, and buyers are 1.8 times more likely to complete a high-quality deal when they use supplier-provided digital tools alongside a rep rather than independently. The job is not to remove sales. It is to arm the buyer to do the first 61% well, then be the vendor they contact.

Deals do not lose, they stall. Forrester research cited by Apollo finds 86% of B2B purchases stall, with buyer teams engaging 22% fewer vendors, down from 3.2 to 2.5. A shrinking consideration set plus a stall rate approaching nine in ten means the marginal lead is worth less than the marginal piece of consensus-building material inside an existing deal.

The paid economics are unforgiving. WordStream’s analysis of 13,474 US search campaigns from April 2025 to March 2026 puts business services at a $5.87 cost per click, 4.85% conversion rate and $93.69 cost per lead, with industrial and commercial at $5.87, 8.20% and $75.19. Business services converts at well under the 8.18% all-industry median and pays 40% above the median lead cost. Capture-only strategies in B2B are the expensive way to buy a small number of people who were going to find you anyway.

How to tell which applies to you

Your situation	What is actually happening	Where the budget goes
Cycle longer than 6 months, flat pipeline	Shortlist formed without you	Brand presence to the out-of-market 95%
Good demo volume, poor win rate	You are the second vendor contacted	Category-defining content, not more forms
Deals reach late stage then stop	Consensus failure inside a 10-person group	Enablement assets for internal champions
High direct and branded traffic, no attributed source	Dark social is working	Self-reported attribution, then fund it
Cost per MQL fine, cost per closed-won unknown	Measuring the wrong object	Account-level reporting over a 12-month window

The rule: if your median sales cycle is 10 months and your attribution window is 90 days, your reporting is structurally incapable of crediting the activity that created the pipeline. Add a self-reported attribution field to your forms and compare it to your analytics. The gap between those two numbers is your dark funnel, and it is usually the majority of it.

What we’d do

TACK has built marketing systems for 300+ brands across 15+ industries since 2009, and we are AI integrators rather than trainers. For a B2B company, the plan splits three ways.

Split the budget between the 5% and the 95% explicitly. Capture demand from in-market buyers with search and retargeting. Build memory with the rest through consistent, distinctive, category-level presence. Argue about the ratio, not about whether the split exists.
Instrument self-reported attribution from day one. A single open field on the demo form asking how they heard about you. It is imperfect and it is still more accurate than a last-click model for a ten-month, ten-person purchase.
Build for the buying group, not the buyer. Security reviews, procurement summaries, ROI models, implementation plans. These are the assets that move a stalled deal through a ten-person committee, and they are almost never in the content calendar.
Report on accounts and pipeline created, not MQLs. With 86% of purchases stalling, lead volume is a vanity number. Our paid media and CRO work in B2B is scored on qualified pipeline over a window that matches the actual cycle.
Be the answer during the first 61%. When a buying group researches without contacting you, the material they find has to be yours. That is the whole argument for SEO, AEO and GEO, and it is how you get contacted first.

Common mistakes

Cutting brand spend because it does not attribute. The channels that put you on a Day One shortlist of 3.6 vendors are the hardest to measure and the most valuable, because the first vendor contacted wins eight of ten deals. Cutting them raises reported efficiency for two quarters and empties the pipeline in the third.

Targeting only in-market audiences. With up to 95% of buyers out of market at any moment, an in-market-only plan concedes the memory-building window to competitors and forces you to win on price at the moment of comparison. That is a permanent margin tax you chose.

Running a lead volume target against a ten-month cycle. At $93.69 a lead in business services and a 4.85% conversion rate, buying more forms to hit a quarterly MQL number produces exactly the leads a 86% stall rate will consume. The cost is a full quarter of sales capacity spent on deals that were never going to move.

The bottom line

B2B marketing is a memory business with a measurement problem. The shortlist forms before you are contacted, so the work is being known, being findable during independent research, and arming the buying group once the conversation starts. Fund the 95% deliberately or lose to whoever does.
