In the marketing industry, we treat experts like they’re village elders, soaking up every tip and trick they have to offer so we can implement them into our own work, desperately hoping for similar results.

But, when you really think about it, marketing is always changing and experts often don’t have visibility into your unique context.

This naturally begs the questions -- what should you do when you can’t find a solution to one of your problems on the internet? To find the answers to your unique problem, consider channeling your inner Sherlock Holmes and become an investigator. Investigators forage for information that’ll lead them to the answers of their own specific questions. And, as a marketer, one of the best investigative tools at your disposal is A/B testing.

Every company has a different set of customers, so there’s no one-size-fits-all formula for designing the most optimal website, crafting the most compelling copy, or building the most effective product. To figure out which website design, line of copy, or product feature will produce the best results for your company, you must discover what your unique set of customers prefer.

To help you do this, we’ve curated eight of the best A/B testing tools for 2019 that’ll help you optimize your website design, copy, product, and, most importantly, help you find the answers to your own specific situation.
