It's incredibly intuitive for non-developers and non-designers. The WISIWYG visual editor makes it easy to quickly create and launch entire experiments. Review collected by and hosted on G2.com.

Its ease of use as a tool and simple integration process with the projects to start using Optimizely. Fast analysis results to see A/B testing results.
Good support team to answer the queries raised. Review collected by and hosted on G2.com.
Currently, the process of raising a ticket and viewing a ticket is a bit hassle due to its migration work in progress. The support is good, but could improve the response time. Review collected by and hosted on G2.com.

My company has had multiple experiences in the past where experiments did not function as expected due to intermittent outages and failures from Optimizely. Review collected by and hosted on G2.com.
Optimizely is like the Ferrari of a/b testing solutions. You can do so much with it. Review collected by and hosted on G2.com.
The learning curve is excellent at times. With power and control comes a price. You have to learn how the system operates. It's not for the faint of heart. At times, tests require a developer. Review collected by and hosted on G2.com.
Optimizely is very user-friendly. I use it frequently for A/B tests and it has helped us to grow the testing program and run and iterate on tests at a fast pace. Review collected by and hosted on G2.com.
There are limitations as to what can be done with the UI versus what needs to be done through code. It would be great to have more UI functionalities so we can continue to test more. Review collected by and hosted on G2.com.
We have been working with Optimizely for several years now and the A/B testing suite has helped us a lot! The tool is easy to use and most stuff is self-explanatory. Whenever we want to test a new feature we just setup a test with Optimizely and wait for the results to come in. Fortunately a lot of tests can be created with their WYSIWYG-editor, so there is no need for any help from the dev department. Review collected by and hosted on G2.com.
Some stuff has been tricky to implement/test for us with Optimizely. Also performance takes a hit when implementing Optimizely, which might be the downside of having a tool with so many features. Review collected by and hosted on G2.com.
It is a powerful tool that allows you to tweak the entire frontend of your site; build features without involving the engineering team. This allows for flexibility and speed, which are essential for testing. Review collected by and hosted on G2.com.
Unable to handle more than 1 person working in the same experiment; limited for productivity Review collected by and hosted on G2.com.
I like the visual editor capabilities that allow someone like myself (not a developer) to create meaningful experiments. I also love the fact that it allows for more complicated experiment construction and the ability to create segments within the tool using data in real time as well as uploading other 3rd party data to inform segments.
