Optimizely Web Experimentation vs. VWO

Let's start with not well suited. As a market-leading tool, they are not the cheapest option available. This means that in some cases, we cannot recommend them to clients as we know they will fall out of their budget. We would recommend them for enterprise and medium—to large businesses as we know we can trust the tool and it comes with a wide range of functionality.

Our marketing team does a lot of creative testing around messaging and imagery. VWO is well suited for this type of testing and can yield great results if you define your conversion goals correctly. However, when we have tried to do more substantial/advanced changes through VWO (such as re-positioning content or modifying elements in a form), we have had some challenges and not been able to get the desired tests working correctly.

• Considers every kind of experiment from simple code change, code additions, code removal, javascript functions, CSS changes, and split landing redirects.
• Very friendly UC interface for easy navigation of implementation of pages, click events, experiment set up, and metric set up.
• The ability to let me know when something has reach stat sig without having to do complicated math on my own
• ability to carry UTM parameters through landing page redirects with a click of a button.

• VWO has a strong support team willing to help provide answers to questions during the setup process. During setup, we had some questions regarding implementation across a significant number of sites and they were able to ease dev team concerns and provide detailed best practices to streamline integration.
• Some of the initial results of a few of the initial tests raised some questions internally. We setup a call and were able to quickly address the questions and find some opportunities to leverage moving forward.
• I discovered a bug within the UI that lead to some questions internally. I was able to report it and the problem was fixed rather quickly and their team followed up with a thank you for reporting it and to report the issue was now resolved.

• Pricing model penalizes those just starting with experimentation.
• High price and fees based on website traffic, not experiment impressions. so you are charged whether you experiment or not.
• Integration with GA4 is subpar.
• Documentation at times confusing, different products.
• UX is confusing and too simple. It leads to errors by users. Lack of meganavs, too minimalistic, it becomes quite a frustration.
• Not competitive pricing compared with other AB testing tools.

• 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

Optimizely Web Experimentation's visual editor is handy for non-technical or quick iterative testing. When it comes to content changes it's as easy as going into wordpress, clicking around, and then seeing your changes live--what you see is what you get. The preview and approval process for sharing built experiments is also handy for sharing experiments across teams for QA purposes or otherwise.

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.

I would rate Optimizely Web Experimentation's availability as a 10 out of 10. The software is reliable and does not experience any application errors or unplanned outages. Additionally, the customer service and technical support teams are always available to help with any issues or questions.

I would rate Optimizely Web Experimentation's performance as a 9 out of 10. Pages load quickly, reports are complete in a reasonable time frame, and the software does not slow down any other software or systems that it integrates with. Additionally, the customer service and technical support teams are always available to help with any issues or questions.

VWO doesn't appear to slow down our website at all, though some customers with adblockers like UBlock Origin have been known to not see entire pages if VWO is making changes to the page at a macro level (background, font, etc). This is rare though.

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.

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).

Training was good, just limited to the onboarding process. They walked through all of the steps it takes to get started in VWO and each of the modules, along with giving us ideas for starting our first test. I feel like it could be better if there was a guided process within the VWO program to continue to educate you along the way, and a way to turn that off for experienced users.

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.

Overall, the implementation of VWO is straightforward. If you've got a straightforward way of deploying code to all of your test pages, either a good CMS or a TMS, then implementation should be a breeze. There is no tweaking to be done to the code itself, and once deployed it has the flexibility to cope with different VWO modules (tracking, conversion analysis, session analysis) without modification.

Overall, the tools we compared against were great, but we went with Optimizely because it has all the features we needed and has the market leadership that gave us trust we would be successful in our experimentation efforts.

I used Google Optimize when it had just launched. It was therefore not yet a competitor to VWO. I haven't used it in roughly half a year time, so a lot has probably changed. I still use Hotjar for certain features that VWO offers, but which I think function better in Hotjar. I for instance prefer the Hotjar heatmaps, because I can elect to ignore certain elements on the webpage, such as a cookie consent pop up. A simple difference which makes me like Hotjar recordings more is that I can view a recording and click next, rather than going back to the overview and selecting the next recording.

This rating for Optimizely Web Experimentation is rooted in the more complicated builds that are not feasible with just Java and CSS. These require the featured experimentation add on, therefore the base level platform I am giving a lower rating. We have had issues with overly complex test builds, because we can only utilize Java and CSS to make the elements

The product seems infinitely scalable for our needs (small business) and we've never had any issue with loading VWO-edited elements. I will say, though, that online customers with ad blockers have been known to not see certain VWO elements as their third-party scripts are disabled.

• Customer retention: We've reduced subscription service client churn by 20%+ using optimized unsubscribe flows.
• Risk mitigation: Testing into full site redesigns has saved clients millions of dollars.
• Feature prioritization: Identifying what painted door changes add value has allowed developers to focus on changes that add hundreds of thousands or even millions to the bottom line.

• The ability to offer a CRO service is greatly enhanced by VWO, as it allows us to run tests for clients
• The editor means to some extent we don't need much developer resource to run the tests, lowering costs of doing so
