Optimizely vs VWO

• Optimizely makes it extremely easy to setup almost any type of split or multi-variate testing experiment. It has a variety of test triggers types & many ways to segment incoming visitors.
• I believe Optimizely's results dashboard is one of the best among split testing software. It allowed my team to get insights into the running of tests, like time to significance and a view of metric changes over time.
• Optimizely is very easy to use for non-engineers. It has a powerful visual interface that allows marketers and advertisers to setup complex variations without 1 line of code.
• In terms of documentation and implementation, I believe Optimizely is ahead of its competitors in terms of its focus on reliability and speed.

• When designing A/B variations I can choose to either use the visual editor or to make the changes using code. I particularly like using jQuery.
• VWO offers the ability to keep long term track of the performance of your goals.
• I can easily identify recordings of users that dropped out of a funnel and watch those.
• There is live chat to get support, with great response times and which is very helpful.
• You are forced to create observations and hypotheses when creating a test, which is a great way to make sure that you are actually testing something worthwhile.
• You can group tests together so that you can rule out interaction effects between tests that you are running at the same time.

• Assistance with on-boarding the tool as opossed to using a partner.
• Dedicated training on the tool for internal business users both on the development and consultancy side.
• Impression usage should be applied to running AB tests only - Development teams need to take some time to implement a winning variation and so using impressions to temporarily run a winning experience is not ideal.

• The user interface within VWO does take a bit of time to get used to, especially as it pertains to switching back and forth between tests. When running multiple experiments on a site at a time, a clear and succinct dashboard for everything in one place would be helpful (as opposed to needing to switch between A/B, multivariate, etc).

• Before using Optimizely, we were shooting in the dark with our design decisions. We'd make a change, then have to wait to see our user numbers drop over the course of a couple weeks, then roll back the changes. Our front end team would get frustrated with the wasted time, and try again. With Optimizely, our decisions are data-driven, morale doesn't take a hit, and we are always moving forward with our site.

• We've been able to roll out new design patterns with confidence that short term revenue is not negatively effected.
• We've had more wins than losses, as the company is just ramping up a testing strategy. We know percentage of wins will go down as we optimize, but VWO has been vital on making calculated steps along the way.
