If a new feature should be added but unsure of how it will actually work or how users will accept the new enhancement or change, this tool allows you test and measure initial results. This saves so much time and energy knowing the results before it is deployed and might have low user adoption or acceptance.

VWO
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.

LaunchDarkly
- A/B or Multi Variant Testing as a methodology to gather insight from customer usage. Experimentation as a feature within LaunchDarkly offers information around the success of one variant over another and whether the experiment has reached statistical significance.
- Being able to decouple deployment of code from the release of a feature is hugely valuable.
- Development teams are empowered to manage features within their production applications for reliability or testing purposes.

- 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.

Cons
LaunchDarkly
- Limited number of users on cheaper plans that is limiting our ability to audit log who is making changes.
- Some of our engineers are confused between flags and segments and have set up items incorrectly.
- Better documented support for React with Typescript.

- 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).

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

It's very easy to create new feature flags and set them properly. It is more difficult to get LaunchDarkly integrated within a distributed system so that flags can be used. Especially on stateless servers where gating features by user is not easy. Overall though, it is very easy to get started and I like how simple it is to use.

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.

From what I have seen, LaunchDarkly integrates well with your code and also services you might have in your tech ecosystem. We use Jenkins for automation and we were able to use it to build pipelines to automate the control of LaunchDarkly toggles in our code.

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.

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.

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.

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.

LaunchDarkly stood out to us because it put control of the application within the hands of our engineers. We didn't want to allow business users to manipulate the production site via a third-party tool. Instead, our focus was on delivering faster as an engineering team.

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.

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.

- Improved developer experience with some teams moving to Trunk-based Development.
- Increased deployment frequency due to smaller code releases.
- Validation of the technical and business value of work is achieved more quickly through smaller pieces of work and through experimenting with a small group of users before a feature gets to 100% of customers.

- 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
