Experiment N:
Assumption: share win on hard game
Prediction: 5% conversion rate
Results: 41 subjects, 10 shares, 24% conversion
Decision: Keep prompt and doing a follow up experiment that prompts users to share when there’s a 65% failure rate on guess game (currently set at 75%)
Experiment I:
Assumption: share top ten
Prediction: 3% conversion rate
Results: 524 subjects, 10 shares, 2% conversion (*due to bug, # of subjects that were actually shown the share prompt is likely less than the # reported)
Decision: Doing a follow up experiment to try to increase this percentage. 2 new versions of share prompt with updated text. 2% determined acceptable though.
Experiment J:
Assumption: signup from duel 2
Prediction: 30% increase in signup Results: All versions had the same signup conversion
Decision: Reverting back to original call to action.
