    Optimizely Web Experimentation

    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.

    UserZoom is well suited for usability testing, I found specifically around test websites and marketing materials. I was able to invite others to participate and watch as well as screen share so that it was an interactive session. Other tools I have used have been a little better with the video output and transcripts of each session so that we could capture notes quickly, but overall it was a good tool to use to test.

    Pros

    Optimizely Web Experimentation

    • 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.

    UserZoom

    • Quantitative testing can be done on the cheap compared to other quant tools or vendors... once you buy the license, you only pay for additional recruiting and you are managing the project, so there isn't the high cost of having other vendors doing the project management or running a survey etc.
    • Farily robust means of tracking and recording data. I also relied heavily on the excel spreadsheet of all the raw data, which you can have UZ customize for you to get what you need.
    • Great support system from the UserZoom team - they have researchers who can help with coding and also provide research support for a very good price.
    • Also they have tree testing, card sorting, survey capabilities (in addition to usability testing)... and mobile testing. and they seem to be continously be developing the tool to support additional methods.

    Cons

    Optimizely Web Experimentation

    • Actual creation of an A/B test is confusing and difficult (like the differences between Pages vs URLs etc.).
    • Setting up a URL Redirect Experiment is so convoluted it seems like it's not even a feature Optimizely wants you to use. Instead, it's like I'm tricking Optimizely into alternating between 2 URLs. That really needs to be cleaned up as it would be very helpful.
    Anonymous | TrustRadius Reviewer

    UserZoom

    • Compared with some other tools, because their video conferencing platform is web-based (vs. using Zoom, which has a desktop app), I find the connection buffers a lot and it's kind of annoying
    • Their screening tool on the UserZoom side (not Go) is clunky. Just let me select May, Must, or Should not for criteria rather than the weird interface design they have now.
    • Logic panel is a little confusing, sometimes I do a double-take, sometimes it's wonky and resets itself. It's just not as easy to use as it could be.
    • They haven't integrated UserZoom and UserZoom Go (formerly Validately)
    • It's expensive!
    • We signed up for a high sample size license with unlimited tests, but we're finding their panel doesn't fill as fast as their biggest competitor, UserTesting. We've struggled to fill n=100 sample tests with fairly general criteria.
    • A lot of their licenses only allow limited concurrent studies, whereas UserTesting had unlimited tests that you could launch at a time. It's slowed us down.

    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.

    I'm actually trying to get a license for my current job at my current company (recently moved to a new company). I gave it this rating because I am about to go to our executive to ask that we purchase it! I know that there will be value because we are forecasting a high volume of research next year

    Without a doubt, after 8 years using various different testing tools, Optimizely is by far the easiest to use. Feedback from developers and more technical teams has always been positive, mostly due to the code editor allowing for easy implementation along with the creation of advanced audience segments using advanced javascript. For business users and non-technical people, the wysiwig editor allows for smaller changes to be made quickly whilst somewhat educating the user on the types of code changes that are being made.

    Overall, it was fairly easy to use. Especially if you are familiar with this type of product. We were able to use it for testing pretty much right after we got it (same day) and didn't have many issues figuring out how to invite, test, and share which was great.

    From my experience, the UserZoom team has really done a great job answering the limited questions we have given them thus far. I think the platform is popular enough that many of my questions have been answered by their help pages - or other online content with helpful tips and tricks. I think the community has done a nice job of providing end-user tutorials for those who are new to the platform.

    The tool itself is not very difficult to use so training was not very useful in my opinion. It did not also account for success events more complex than a click (which my company being ecommerce is looking to examine more than a mere click).

    In retrospect:- I think I should have stressed more demo's / workshopping with the Optimizely team at the start. I felt too confident during demo stages, and when came time to actually start, I was a bit lost. (The answer is likely I should have had them on-hand for our first install.. they offered but I thought I was OK.)- Really getting an understanding / asking them prior to install of how to make it really work for checkout pages / one that uses dynamic content or user interaction to determine what the UI does. Could have saved some time by addressing this at the beginning, as some things we needed to create on our site for Optimizely to "use" as a trigger for the variation test.- Having a number of planned/hoped-for tests already in-hand before working with Optimizely team. Sharing those thoughts with them would likely have started conversations on additional things we needed to do to make them work (rather than figuring that out during the actual builds). Since I had development time available, I could have added more things to the baseline installation since my developers were already "looking under the hood" of the site.

    Alternatives Considered

    Optimizely Web Experimentation

    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.
    Sylvia Flores | TrustRadius Reviewer

    Most comparative products that we've used/seen are in-house developed tools, data scientist-based research with a few other tools used in the process such as Validately. UserZoom is a nearly perfect tool as results are real-time, authentic and can capture real-experience results at scale. The increase in pricing came when so few purpose-built alternatives followed suit.

    It's all you need to design, install, analyze and measure simple tests with Optimizely. When test complexity increases, it becomes necessary to integrate third party analytics tools to perform more detailed analysis such as additional details like page views, average time spent on each page, and bounce rates by variation. Optimizely has very straightforward integrations, so integration with analytics is straightforward.

    Return on Investment

    Optimizely Web Experimentation

    • Optimizely has had a tremendous positive impact on the ROI of our clients. Whether you're just starting your testing program and just want to get your feet wet with a few simple WYSIWYG tests, or you're ready to dive in to complex MVT test designs and Personalization Campaigns, Optimizely has everything you need to create, and maintain, a highly successful testing center.
    Anonymous | TrustRadius Reviewer

    • Overall the ROI has been fairly useful. The price for the tool itself on occasional use cuts into our profit margin, and as I mentioned previously it's difficult to predict how much UserZoom will charge for a given project.
    • On a positive note, UserZoom allows us to run projects that we wouldn't be able to on any other tool. We have landed projects with new clients that wouldn't be possible without UserZoom, so that helps drive future business in other areas.
    • On the negative side, the fact that UserZoom also provides consulting research services means we can sometimes be in direct competition with them over clients, which allows them to beat our pricing since they own the tool. All's fair in love and war, but it is a tricky situation.
