Long sales cycles. Months, not minutes from first touch to close. B2B marketing has to keep buyers warm without burning them out — and stay credible across the whole stretch. Lead nurture isn't a feature you bolt on at the end. It's the whole game. The campaigns that work in DTC die quietly in B2B because the buyer isn't ready when the ad runs.
Multi-stakeholder buying. A B2B purchase decision rarely involves one person. It's a committee — technical evaluators, procurement, finance, operations, the executive sponsor. Each one needs different content at different stages. The marketing has to feed all of them, in the right order, without losing the thread. That coordination is where most B2B marketing programs fall apart.
Spec-sheet purchases. Your B2B buyer often knows more about the product category than your sales rep does. They've read the data sheet, downloaded the comparison table, watched the YouTube reviews, and called two of your competitors before they ever filled a form. The marketing has to be technically credible — not surface-level "thought leadership" written by someone who has never touched the product.
