For me, GuessTheTest is a regular reminder not to trust my gut instinct - and this is a lot cheaper than learning that the hard way!It's also my go-to source for A/B testing case studies, which means I can show clients the value of data-driven marketing using the most relevant examples.
I've been a subscriber of GuessTheTest for some time now. I enjoy their weekly experiment deep dives where you have to think about which variation won. Often the answer surprises you. The write-up for each experiment is quite detailed and helps you to apply the same type of thinking to your own optimisations.
I have been using GuessTheTest for several years now and it's one of the best platforms to access and engage with the resources around A/B testing and understanding the psychology behind driving conversions on websites and apps. The depth of the content is extremely valuable. It brings together thousands of $$ worth of research at our finger-tips. And the gamified way to answering and engaging with content is very exciting! I would definitely recommend following this platform on a regular basis.
This is a website for a/b testing and optimization. It leads the industry for best practices and ideas for improving websites. It is the top source for website optimization. I highly recommend this site!
Great information source about A/B testing on real examples with all the analysis. Really happy that i found it. Recommended!
