Do you ever do A/B tests?

Hi everyone! I am a beginner shop owner and I am just starting to learn about selling online more closely to make my store profitable. One of the ideas for researching the market that I’ve read about is A/B testing. The idea is basically trying to publish the same product under different categories and with slightly different information to see which listing will sell better. Did anyone actually tried to use this thing? I find it interesting just not sure if it’s worth the time and effort. I would highly appreciate any and all experience you guys can share. Thanks a lot!
