I ️ designing, iterating on, sharing and learning from quality online experiments — especially when it inspires successful replication by growth and experimentation teams. UI Design (since ~2000) × Experimentation (since 2014). And that's how GoodUI came to be. I'm actively building a repository of experiments (with winning, flat and losing results) to separate the more generalizable UI, interaction and copy patterns from the more noisy and less predictable ones. We do this by grouping and meta-analyzing similar a/b tests together under patterns. Of course I could not have started this project without help and input from leading experimentation teams at companies such as: Microsoft, Thomasnet, Backstage, Yummly, Elevate, Designlab, Reverb, VivaReal, ZAP, Volders, Rollbar, Kenhub, Expert Institute, Drip Agency, CXL, to name a few. A big thanks to those! Over time, by actively replicating similar experiments together, some patterns are becoming stronger, better and/or more generalizable - quite useful for making optimization work a little easier. :) I am also known to pay attention to leaders such as: Netflix, Amazon, Airbnb, Bol, Booking, Etsy and Walmart by simply observing what UI changes they A/B test and then write about such "leaked" experiments at: www.goodui.org/leaks
