Budget Challenge: $???

• Given– We have 10 names to test– We will test each one on 10 different people– It costs $1 for each test (i.e. to buy an ad)

• How much money do we need?

Budget Challenge: $100

The 4-Hour Workweek (of course)

How else could this have been tested?

Sample Test Results

• Twitter converts 2% of people• Facebook converts 10% of people

A/B Testing Execution

• Given 3,000 people• A/B test for the first 300 (10% of them)– 6 different campaigns with 50 tests each

• Then test final 2,700 people with best campaign.

• Results– Worst campaign (Twitter) converted 2%– Best campaign (Facebook) converted 10%– Difference between 54 and 270 people.– For a $50 product, that is $10,800!

Budget Challenge: Implementation

• Implement Twitter login: $10• Implement Facebook login: $15• Implement LinkedIn login: $20

• But we only have $10!?! What do we do?
