Headline A/B tests now run for 4 hours on low-traffic sites

You can now run Headline A/B tests for up to 4 hours. If your site sees lower traffic, your experiments finally get the runway they need to reach a reliable result.

Not every site gets the same volume. Shorter test windows penalize lower-traffic publishers: experiments end before reaching reliable conclusions, and the results are inconclusive by design. A 4-hour window levels the playing field.

Here’s how you can get started:

• Set the experiment duration to 4 hours when creating a new Headline A/B test
• Your test runs long enough to gather the data it needs before calling a winner
• Get reliable, statistically sound results even on lower-traffic pages

This applies to all Headline A/B tests. No configuration changes are needed outside the duration setting.

More time. Better data. Clearer winners.
