Overall Satisfaction with Optimizely

Use Cases and Deployment Scope

We selected Optimizely as our main tool for a/b testing after trying Google Analytics Content Experiments and Visual Website Optimizer. It's easy to use by everyone in the Marketing team so they can quickly test their ideas.

Pros and Cons

Pros

It's very easy to use.
Their support is excellent.
On the technical side you add the code to the site only once and you don't have to create a new page for variation.

Cons

With bigger sites you can reach the monthly visitors limit pretty quickly.

Return on Investment

We managed to increase our trial conversions.

Alternatives Considered

Google Content Experiments,Visual Website Optimizer

With GA Content Experiments you should create a new page for your variation, it doesn't really offer WYSIWYG interface where you can just make your changes. It also requires a new code to be added for each experiment. The multi-armed banded approach didn't work for us and back then they haven't released the 50:50 option.
Visual Website Optimizer is more like Optimizely, but ultimately we were impressed by their customer support.

Likelihood to Renew

It's proven as the most used tool by the marketing people compared to the others we've tried.

Likelihood to Recommend

It's perfect if you want to run tests without much involvement from IT department.
