Great idea! 🚀 As a Web Analytics & Conversion Tracking expert, I can say that running competitions around funnels, structures, ad copies, creatives, and incrementality measurement could provide some valuable insights. While it’s true that success in these areas often requires testing to measure effectively, setting up clear metrics and KPIs for each competition could help determine winners. It would be interesting to compare the results and identify patterns, and over time, those insights could guide more efficient optimization strategies. Just be sure to have proper tracking in place to measure incremental impact accurately! Let me know if you need any help with setting up the tracking for these tests!
