From the leaks I find, I choose one change that should give the biggest boost (for example, a new headline, hero video, or button text). The plan explains:
• what we will change and why,
• the goal we will track (like added sales or sign-ups),
• how long we must run the test so we have enough visitors to know the result is real and not just luck. (Math pros call this “statistical significance.”)
