A/B testing for boards

[jace]

Board titles, captions and descriptions should have A/B versions for testing which variation works best to convince someone to stay on the page. Unlike job posts, this isn't a test for click-through to the full post. The user is already here and has arrived from an uncontrolled source. The test metric is whether the combo results in a bounce or a further click-through.

For simplicity vs effectiveness, we may do A/B tests in either of these combinations:

1. Title, caption and description all as one test group
2. Title+caption as one test group, description as another (so the results are actually for A/B/C/D)
