1,5% Average conversion rate of paid search (PPC) in B2B Paid search converts lower than SEO and email, but reaches people actively searching right now. It's a speed channel, not a replacement for organic growth. Source: First Page Sage (2026)

1 op 5 Share of B2B deals that take more than a year to close (1 op 5, i.e. roughly 1 in 5) Most prospecting sequences run 4 to 6 weeks, but a fifth of deals need more than a year. B2B sales demands patience and sustained presence. Source: Sopro, State of Prospecting 2026 (2026)

2,8% tot 11,8% Lead-to-opportunity ratio in B2B, depending on the sector (2,8% tot 11,8%, i.e. 2.8% to 11.8%) Of every 100 leads, only a handful move on to a real sales opportunity. The quality of your leads matters more than the count. Source: First Page Sage (2026)

6 tot 10 Number of decision-makers in a typical B2B buying team (6 tot 10, i.e. 6 to 10 people) A B2B purchase is rarely one person's decision. Your content must convince multiple roles, each with their own questions and objections. Source: Gartner (2024)

67% Share of B2B buyers who prefer a rep-free purchasing experience Buyers prefer to research on their own, often digitally and with AI. That leaves only a fraction of the buying journey for a rep to make a difference. Source: Gartner (2026)

~5% Share of your market that is actually purchase-ready at any given moment About 95% of your potential buyers are not in-market right now. Chasing only the active 5% means missing everyone else who will decide later. Source: LinkedIn B2B Institute / Ehrenberg-Bass (2024)

What do these figures mean for Belgian B2B companies?

The common thread is clear: B2B lead generation is about quality and patience, not volume. The best-converting channels (SEO, email, ABM) reach people with real intent, and the cheapest leads come from trust, such as referrals. The gap between $25 and $463 per lead shows that the channel can make or break your margin, but only if you measure through to the sale.

More importantly: a purchase is a group decision made by six to ten people, who work through most of their buying journey on their own. 67% even prefer a purchasing experience without a rep, and one in five deals takes more than a year. And at any given moment, only about 5% of your market is actually purchase-ready. Chasing only that 5% means missing the 95% who will decide later. For a Belgian B2B company, that means: build a thoughtful lead generation strategy that keeps multiple decision-makers engaged, and account honestly for cost per qualified lead, not the number of forms. Steer on customers and revenue, not lead volume.

Frequently asked questions

Which channel delivers the best B2B leads? +

On conversion, SEO, email and account-based marketing score highest, while referrals are the cheapest per lead. But the best channel is the one that delivers qualified leads and revenue for you, not whichever tops a benchmark. Always measure through to the sale, not just the form.

What's a good cost per lead in B2B? +

It varies enormously: from a few tens of euros for referrals to hundreds of euros for paid search or events. A low cost per lead means nothing if those leads never close. Track cost per qualified lead and, ultimately, cost per customer, weighed against your order value.

Why does B2B lead generation take so long? +

Because a B2B purchase is a group decision made by six to ten people, who prefer to work through most of their buying journey on their own. Over two thirds of buyers even prefer a rep-free purchasing experience, and one in five deals needs more than a year to close. Your leads warm up slowly. That's why it works better to stay present with future buyers than to only chase the ones ready to sign today.
