| 1 | # Content Experimentation Best Practices |
| 2 | |
| 3 | Principles and patterns for running effective content experiments to improve conversion rates, engagement, and user experience. |
| 4 | |
| 5 | ## When to Apply |
| 6 | |
| 7 | Reference these guidelines when: |
| 8 | - Setting up A/B or multivariate testing infrastructure |
| 9 | - Designing experiments for content changes |
| 10 | - Analyzing and interpreting test results |
| 11 | - Building CMS integrations for experimentation |
| 12 | - Deciding what to test and how |
| 13 | |
| 14 | ## Core Concepts |
| 15 | |
| 16 | ### A/B Testing |
| 17 | Comparing two variants (A vs B) to determine which performs better. |
| 18 | |
| 19 | ### Multivariate Testing |
| 20 | Testing multiple variables simultaneously to find optimal combinations. |
| 21 | |
| 22 | ### Statistical Significance |
| 23 | The confidence level that results aren't due to random chance. |
| 24 | |
| 25 | ### Experimentation Culture |
| 26 | Making decisions based on data rather than opinions (HiPPO avoidance). |
