Most businesses choose their marketing channels based on familiarity, not data. They run Facebook ads because they have always run Facebook ads. They go to trade shows because they went last year. They invest in LinkedIn because someone told them it is where B2B buyers are.
What they rarely do is look at the actual cost-per-lead data across channels and let that inform where the budget goes.
When you do look at that data, the results are sometimes surprising — and almost always actionable.
Start with webinars. Research from Zoom and Cvent consistently puts the average cost per lead for webinars at around $72. [1] For a channel that many businesses treat as a secondary tactic, that is a remarkable combination of quality and efficiency. Webinar attendees have self-selected into a high-engagement format. They have given up an hour of their time to learn something specific. That is a level of demonstrated intent that most other channels cannot match at anywhere near that cost.
Now look at trade shows. The average cost per lead from trade shows sits around $811 in 2025, rising toward $934 in 2026 as booth, travel, and labor costs increase. [2] That is not a typo. Trade shows are among the most expensive channels available for prospect acquisition — and yet they remain a default budget item for many B2B organizations, often justified by vague arguments about brand presence and relationship building.
The channel-by-channel comparison gets even more instructive when you look at the full picture. Referrals come in at roughly $25 per lead — the cheapest source available, and often among the highest-converting because they arrive with built-in trust. [2] Facebook ads average around $142 per lead. LinkedIn and paid search vary significantly by industry but tend to run higher.
None of this means trade shows are always wrong or that webinars are always right. Channel effectiveness depends on your industry, your audience, your sales cycle, and your ability to follow up effectively. A trade show lead that closes at 40% might be more valuable than a webinar lead that closes at 5%.
But that is exactly the point. Most businesses do not know their close rates by channel. They do not know their cost per SQL by channel. They do not know their cost per closed deal by channel. They know their cost per lead — and they optimize for that number without understanding whether the prospects they are generating are actually worth what they are paying.
The businesses that are winning on channel strategy right now are doing the full math. They are tracking prospects from source to close, calculating true cost per revenue dollar by channel, and reallocating budget toward the channels that deliver the best return on the full funnel — not just the cheapest entry point.
For most businesses, that analysis reveals at least one channel that is dramatically underperforming relative to its budget allocation, and at least one that is underinvested relative to its potential. The opportunity is in closing that gap.
