It is a little too limited for a full stack experimentation programme. Many times we required development support or tech advise but we were simply unable to get this due to it being google. This was a big problem for us. However it is quite good if you were looking to get started in experimentation and didn’t have the budgets for a wider tool
It's great to develop business applications. Previously, we tried different technologies but we find it the most suitable for us. We also deploy a generic backend so we don't need to install anything new to implement new applications. This helps us to develop very fast and with very low effort.
Easy to follow set up procedures. Once I walk a client through the process, it's effortless for them to emulate on subsequent tests.
Lots of geo and user attribute customization features to be able to drill down into specific targeted audiences — all based on the power of Google's immense data system.
Google Optimize is the logical choice for many people to start with since most are already familiar with and using GA.
Google Optimize being part of the Google stack makes it great in reporting and analysis. Wish Google would add more features like dynamic tests, multi funnel tests, conversion calculator based on the total number of traffic of the page being tested instead of using the websites total traffic. Should integrate form analysis, heatmap, and page analytics.
Each of the above platforms offer a specific solution. Sencha provides a complete solution that is a library of components as well as a framework to modularize your application so that it's better manageable. Once you get over the learning curve of the whole technology it's a breeze to implement new functionality within the application. We have an aggressive client who comes to us every other day with some new requirement, and sencha has been able to answer all of those without issues.
