Ultimate SnowShoes wants to improve their conversion rate for the Winter Warehouse sale. What is a best practice for Ultimate SnowShoes while they’re testing ad copy?

Limiting the number of ad copy versions tested at one time is a best practice because it allows for statistically significant results to be achieved more quickly. Testing too many versions simultaneously dilutes the traffic to each ad, making it harder to determine which variations are truly performing better due to insufficient data. While testing is crucial, the goal is to gain actionable insights efficiently. Including both landing page and ad copy tests simultaneously can confound results, making it difficult to isolate the impact of ad copy changes. Keeping ad copy generic is generally not a best practice as specific and compelling ad copy tends to perform better.
