Opening-line test: which first line works better?

The opening line decides whether people click “…more”. On the Opening-line test card in the post editor you can try two different first lines with the same post. It only starts when you explicitly ask for it – per post.

1. 1Open the post and click Set up a test.
2. 2A is the post's current first line. For B, pick one of Claude's suggestions or write your own – a really different one (a question, a number, a personal moment, a bold claim).
3. 3Choose where and when B goes out: another channel of the brand, or the same network on another day.
4. 4Tick that both versions may be published and start the test. B waits for your approval as a draft.

How is it decided?

• Once both versions have been live for at least 3 days, we compare their engagement rates (interactions relative to views). If a network reports no views, we compare the number of interactions.
• Clear winner: about 95% sure it isn't luck. Likely winner: about 80%. Otherwise it's neck and neck.
• If B went to another channel, the audience differs too – then the result is a strong hint, not proof.

What does Sayweek learn from it?

It favours the winning kind of opening (for example a question or a number) in your next posts, and the opening-line picker shows next to every suggestion how often that kind won in your tests.
