B2B agency selection FAQ

What marketing leaders ask before choosing an agency.

Straight answers drawn from Carbon’s national study of how B2B decision-makers discover, evaluate and reconsider business partners.

What do B2B buyers look for in a marketing or advertising agency?

B2B buyers look for proven expertise, credible results, trust, clear value and a business case they can confidently defend internally.

How do B2B decision-makers discover new agency partners?

B2B decision-makers discover partners through professional networks, search, peer recommendations, social platforms and AI tools. A coherent multi-channel presence helps an agency enter the shortlist.

In Carbon’s study, 78% of respondents use AI to research partners at least sometimes, and 48% said AI introduced a provider they seriously considered.

What can B2B marketing agencies do to become easier to choose?
