True or false: MQLs are the best way to measure marketing's contributions to pipeline.

• A. True
• B. False
• C. Not sure
• D. Only for certain industries

Answer: (B)

Measuring marketing's impact on the pipeline is about how marketing activities translate into opportunities and revenue, not just how many Marketing Qualified Leads are produced. An MQL is a screening signal that helps prioritize leads, but it doesn't guarantee sales readiness or actual pipeline contribution. Lead volume can be high while the quality-to-conversion is low, and some campaigns drive meaningful pipeline with relatively few MQLs if those leads move quickly through the funnel. Definitions of what counts as an MQL vary, which makes it a shaky single metric for marketing's overall contribution. The stronger approach is to track pipeline- and revenue-related outcomes—marketing-influenced pipeline, SQL conversion rates, time-to-close, and revenue attribution across touchpoints—often using multi-touch attribution. Therefore, the statement is false.
