In the software world, it's easy to do A/B testing where a website introduces two versions of the same information to test which one users prefer.
I'm wondering if it's possible to do something similar with book titles: To create two books with the same content but different keywords in each title. Then, publish both and see which does better.
For example: Dish Washing for Authors vs. Dish Washing for Writers -
In the era of self-publishing, ebooks, and print on demand, the barrier to doing this seems minimal.
So, is this allowed? Is this sensible? Is this considered bad practice?
