headstone from Google Graveyard
When we last had Melanie Bowles as a speaker in 2019, she lead an informative session on building a sustainable experimentation strategy. Since nothing at all has changed since 2019, we just replayed that talk and then everyone went home. While I’m obviously being facetious — much of the strategies that Melanie laid out in that talk are still very relevant! The landscape has changed a lot since then, from big changes in browser privacy and client-side technology to the shutdown of the most widely used tool in the industry, Google Optimize.
While there’s no clear successor to Optimize, there are many good testing tools out there, including popular options like: AB Tasty, Convert.com, Visual Website Optimizer, Optimizely, etc. Most of these tools do also offer integration with GA4.

Deployment count of tools via BuiltWith data
As you can see from this chart based upon deployments in the top 1M sites, none of these tools are exactly catching fire with popularity. A big reason for that may be that none of them are free for unlimited usage like Optimize was. Melanie also pointed out that A/B testing and similar functionality like feature flagging has in some cases moved into all-in-one suites like Amplitude, Salesforce, etc. The sunset of Optimize can be looked at as a chance to mature our A/B testing practices, and focus them where they can have the most impact.
Melanie also suggested that we embrace AI tools, especially on the ideation side of testing. There’s no substitute for human expertise when building out tests, but it’s certainly not cheating to let ChatGPT come up with some potential variations for your test! Just remember to give the AI as much context as you can. Melanie ran through a quick example which included providing the AI with a customer persona, which you can find in her slides below!
As a new twist for the meetup in 2025, we’re making a donation to a speaker-selected non-profit at each event. Melanie chose to designate Columbus Cultural Orchestra — a program for young people 13-25 to develop their musical skills and enhance diversity in orchestral music — for a $250 donation!
