B2B Agency Vetting Benchmarks 2024

B2B Marketing Agency Vetting Statistics and Benchmarks 2024

Only 23% of B2B marketing agency partnerships hit year-one pipeline targets, according to a 2024 B2B marketing partner performance study based on 287 B2B partnerships sampled between Q4 2023 and Q1 2024. That is the number you bring to the discovery call when an agency starts waving decks instead of citing data.

The 18 benchmarks below sit in five categories: Onboarding and Ramp, Pipeline and Revenue Attribution, Content and SEO Execution, AI and Automation Adoption, and Operational Discipline and SLAs.

Most agency vetting content is qualitative and unciteable. This page is built to be cited. If you're a VP Marketing, CMO, or CEO at a B2B tech or complex-sale org about to sign an agency, use these numbers to pin them to reality. If it's not a number with a source and a date, it doesn't belong in your procurement doc. Numbers beat narratives. Baselines beat bravado.

These benchmarks are the speed limit signs, not the road trip. They tell you what good looks like in 2024 so you can set SLAs, score discovery calls, and sanity-check timelines for a predictable, AI-augmented pipeline engine built on fundamentals-first AI.

Methodology

We built this because we've watched too many teams hire agencies on vibes and pay for it in pipeline. The Starr Conspiracy compiled these 18 benchmarks from seven primary industry research publishers between January and August 2024.

Primary source categories:

• 2024 B2B Marketing Partner Performance Study (March 2024)

Data collection window: January 2024 through August 2024. Publication dates of source studies range from Q4 2023 field periods through Q2 2024. Each statistic was verified against the primary source publication, with publication date recorded to the quarter where available.
