The field of A/B testing continues to evolve, and professionals looking to stay ahead need fresh ideas from thought leaders on the cutting edge. So, who are the current thought leaders in this space? Who can you follow to learn something new and insightful?
We researched hundreds of names to compile a list of the 60 top influencers in A/B testing in 2022.
How we picked these top influencers
Our team selected experts based on the quality of their content, their activity on social media, and their standing in the experimentation field. Criteria included:
- Do they primarily work in A/B testing and experimentation?
- Have they recently spoken at events dedicated to optimization?
- Have they recently published articles, papers, or books in the field of experimentation?
- Do they regularly post content on social media related to A/B testing?
- Do they have a large audience of followers and subscribers?
- This list also weighs voices active in English-speaking markets.
Finally, we also made it a priority to include more underrepresented voices. For example, women comprised 18 percent of our 2021 influencers list. This year, they make up 41 percent.
Inclusion onto or exclusion from the list is not a judgment about skill or experience.
Dozens of world-class experimenters choose not to maintain a regular public presence.
Instead, this list highlights "followability." It is meant to help readers who want to learn about trends in A/B testing from influential and active voices in the space.
This year’s influencers are all below. They are presented in alphabetical order, per their last name.
