Great A/B and Multivariate tool for any budget

What do you like best? Optimizely starts as a free tool which is great. This makes it accessible to companies of all sizes. There are surprisingly a ton of capabilities with the free tool in terms of running quick split tests. I haven't had a need for the paid version of the tool yet. What do you dislike? There have been some instances where the preview of the test page doesn't match what is actually seen live. Given that it is a free tool I would expect there to be some bugs like this. ...

Great product for A/B testing on your website

Great product that could use a few tweaks to make it perfect.

What do you like best? The ease of use and the accessibility of the product. It's easy to set up and monitor projects. The qualitative focus on analytics is great. What do you dislike? Built-in Tracking code for tracking capability needs to be a little more advanced. Each project needs to be reviewed and most likely edited based on our HTML code. Usual issue is with H2 headers and IDs. I also don't like the inability to export multiple tests into one CSV file to compare data. ...

You could be testing in just minutes

Optimizely has made a lot of updates to their statistics engine, latest round of changes upset a lot of people, but it's still doing a great job presenting very complicated data in a simple way. ...

Amazingly engineered product with a very tech-savvy and responsive team and a solid future

What do you like best? I love the technical prowess of everyone I have met at Optimizely. The engineers and support folks have without exception, all been very smart and their customer service is really special. And I say this after dealing with many tech vendors .
