What does the company do well? Optimizely has a lot of options to easily change elements and has more advanced features that is lacking in some of the newer free tools like Google Optimize.
What does the company not do well? Generally, if you need to do something advanced it can require reaching out to support. At this time the pricing is a bit higher than when I first started using the platform.
What about the company do you wish you had known before purchasing? When I first started using Optimizely they had a pretty substantial free plan and email support. Now the price is much higher and there is no free support at all. They have shifted more to Enterprise customers or really heavy A/B testers.
