The lesson
Build a keynote from a shared problem to one hard ratio, then give each fix a named customer and a before-and-after test.
The cover reads "THE OPTIMIZELY EXPERIENCE" with "Dan Siroker, Co-Founder & CEO, Optimizely" beside a blue dotted panel. The talk argues attention is shrinking, says "stop yelling louder", cites a 92:1 imbalance between spend on traffic and on conversion, then gives four moves, each with a named customer and a test result.
The 92:1 ratio belongs to Optimizely's argument, so don't reuse it. Keep the order: problem and number first, then proof for each fix.
