Optimizely

Optimizely is a great A/B testing tool for any size business. The Optimizely platform democratizes A/B testing through a simple interface, excellent training tools, easy implementation and low dependence on IT resources. Utilizing Optimizely I've been able to run robust experimentation programs with a variety of resources (acting as a 1-person team with limited access to IT resources as well as managing a team with high access to resources). Additionally, Optimizely is well-priced and positioned to be affordable for a variety of business sizes.

VWO makes implementation and integration easy. They have done a great job to ensure the script does not heavily impact load times or page speeds. This was a very important aspect especially if you will be doing tests across multiple sites or products. Overall the UI is easy to learn and the support team is quick to address specific questions.

Pros

Optimizely

  • 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.

Cons

Optimizely

  • 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.

VWO

  • 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).

Because it's an incredible and essential tool for my line of work as a conversion optimization specialist. Really couldn't do my job nearly as effectively without it. It's paid for itself many times over and I feel like I'm only beginning to unlock the tools potential.

It's great value and we think we've ironed out all the major teething troubles. However, if we experience any more bugs or problems that significantly slow us down then we're seriously considering switching to Optimizely, which I haven't personally tested but have heard great things about from my CRO peers

I've heard great feedback from the Marketing and Development team who use the tool. I am not particularly great with code but find it easy to set up tests on my own and feel confident putting them live using the preview tool.

I gave Visual Website Optimizer a rating of 8 because it is overall a great product to use. Setting up and keeping track of various tests is easy and straight forward. The only reason why this product is not rated higher is because the support documents online leave a lot of room for improvement.

They always are quick to respond, and are so friendly and helpful. They always answer the phone right away. And [they are] always willing to not only help you with your problem, but if you need ideas they have suggestions as well.

While their online document support is lacking a simple email to their support team will almost always get responded to the next day. It has however taken more than one email to explain the problem to the support team till they understood the problem. The solution I was given also only half fixed the problem the rest I figured out on my own.

Ensure that your Optimizely JS script is loaded in the header of the page. The reason for this is that the DOM loads the page, and if you are changing elements on the page in your variation, Optimizely needs to know this before the page loads so that it can make those changes for your variation.

Alternatives Considered

Optimizely

I think that Optimizely is more user-friendly than Adobe and Monetate, for example - Adobe is really suited for people with deep pockets and a distinct technical acumen that may not be suitable for a small business. Montetate is not user-friendly - even for seasoned marketers. Apptemize is a pretty great product but they killed their free product. Like Optimzely, they seem to be shooting for enterprise-level clients.

We have used conversion.com and Lucky Orange. This is the 3rd CRO tool we have purchased. I think VWO is better than the other two. We also evaluated Optimizely and VWO was the clear winner in terms of price and functionality. The one thing that VWO lacked that Optimizely had was the ability to add custom dimensions to users for more granular business-specific testing segments.

Optimizely offers excellent testing features and incredible technical support and training resources enabling non-technical teams most benefited by experimentation to truly own this function. Optimizely is easy to implement and use, has simple integration with other technologies making it a staple in our marketing technology stack. Finally, Optimizely continues to innovate around its core technology to add new features and capabilities to improve the overall experimentation process (such as acquiring Experimentation Engine in 2018). In a dynamic and ever-changing marketing technology landscape expect to continue using Optimizely in my marketing technology stack for many years to come.

Return on Investment

Optimizely

  • 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.

VWO

  • 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.
