Performance Marketer

ncklrs/startup-os-skills
204 installs40 stars
Summary

This is your performance marketing brain for paid acquisition and conversion optimization. It covers the full stack: writing ad copy for Google/Meta/LinkedIn, setting up A/B tests, optimizing landing pages, calculating CAC/LTV ratios, and building attribution models. The frameworks are practical, like the 70-20-10 budget allocation rule and a channel selection matrix with typical CAC ranges. What I like is it treats performance marketing as a system, not tactics. The anti-patterns section alone (scaling too fast, optimizing for clicks instead of conversions) will save you real money. Use it when you're setting up campaigns, analyzing funnel metrics, or deciding where to allocate budget.
