Hey, does anyone running overlapping tests on Growthbook? :upside_down_face: :ab:

Do you mean tests in parallel on the same page?

We do have users doing this and some use <https://docs.growthbook.io/features/rules#namespaces|namespaces> if they want the experiments to be mutually exclusive.

Generally, meaningful interactions between tests are actually quite rare, and keeping a higher rate of experimentation is usually more beneficial (if this was the concern). We have <https://docs.growthbook.io/using/experimentation-best-practices#interaction-effects-and-mutual-exclusion|more guidance> on the topic, too.

Yeah, we use namespaces.
I always keep my experiments within 50% of the namespaces, so that if anyone else wants to run a test, they can get started straight away by using the other half of the namespace.

It does mean the tests have to run for twice as long, but I think this is worthwhile given that we avoid having to pre-schedule tests to avoid clashes.

And also condition groups this makes selection/targetting easy and also can help preventing overlapping experiments.
