Lead-to-Opportunity Rate
This rate doesn't measure how many leads you generate. It measures how many of those leads deserved to be generated in the first place.
“Doubling lead volume while halving the opportunity conversion rate isn't growth. It's the same result, with more work for sales.”
Otto GTM ObservatoryThe signal that precedes every other pipeline problem
Lead-to-Opportunity Rate is the first real reality-check on a lead: after initial qualification, does it turn into a concrete deal or fizzle out? A stable rate over time indicates coherence between who marketing attracts and who sales can actually move into pipeline.
When this rate drops while lead volume rises, it's almost always a sign that marketing is widening targeting beyond the ICP to hit volume targets, sacrificing quality for quantity.
Anti-patterns
Common mistake: evaluating marketing campaigns only on lead volume generated, ignoring how many of those leads actually turn into real pipeline opportunities.
Second mistake: comparing the rate across very different channels (in-person event vs. downloadable content) without weighting for the maturity and intent of the lead generated by each channel.
Practical Application
Of 287 SALs generated in a quarter, 94 become real pipeline opportunities: a 32.8% rate. Segmented by channel, referral leads convert at 61%, while industry event leads convert at only 19%: reallocating budget toward the referral program brings the aggregate rate to 41% the following quarter.
