VWO started off as a typical website testing tool, with visual selection tools (i.e. no coding required) to create a range of dynamic A/B and multivariate tests. They started to implement some new functionality and now, they have an advanced and fully comprehensive testing and optimization solution. You can create hypothesis and theories for each test with the top-tier of their product, whilst making observations along the way (during the life of each test). This can help you to better understand what you're doing, what's working and how future tests could be conducted to better the outcomes.

The basic solution is good but feels somewhat limited in comparison to their top-tier optimization product. However, their pricing for all products is expensive. Their optimization product (full suite of tools) is far too expensive for most businesses and requires a lot of management time - it's not a case of switching on a button and seeing results, the tools only enable you to create tests and track their progress. It's an ideal tool for a larger team of marketers and website testers.

Over the last several years I've run a lot of tests, and it's been pretty good. We've had some good wins. On the other hand, if every successful test really increased our conversions by the percentage amount each test claimed it did, I'd be typing this review on a mega-yacht in the Med right now, so there's something about testing that seems to make it over-state the gains you get. Not sure what the other factors are or why, though I have noticed that if you let a test run long enough, long after you get a statistically significant result from the test, eventually pretty much all tests converge or come darn close to converging (i.e. no difference between version A and version B). That's definitely led to a lot of disappointment over the years, but we did get a few huge wins that really stuck and were verified over the years whenever we'd re-test them or accidentally re-test them (for example by accidentally running the old version of the page for a while and seeing sales drop).

It's super-easy to set up tests, whether they're tests using the built-in editor to edit individual pages or spilt tests where the test redirects the control page to a different url. Both are good, and the results are easy to understand. The only thing that's funky is you might start a test and get to 95% right off the bat, then later it drops way less than that and you're like "well gosh, you were a lot more sure back then!" But I guess that's the stats talking, not VWO. Overall in testing I've done with VWO, I've discovered that there is way more variance/luck than you might think, and it really is best to run tests a long time, even if it seems like you have a winner quick.

While goals are easy to set up, it can be pretty tough to analyze certain things, like aggregating lifetime revenue for version A versus version B... You have to manage all the cookies yourself using a third party platform, so we eventually gave up on it because it was so complicated. If you just want to compare revenue at time of conversion, though, you can do it, just need a little help from developer to pass the checkout amount to the VWO tracking code so that it gets recorded by VWO for that version of test.

The support is kindly even if they were not able to solve the bugs

A significant part of the users cannot see the a/b test. The deploy function doesn't work properly. At least 10% of the users see alway the old code. Google spider doesn't see the deploy version. So for instance you cannot use to deploy SEO code.

We will never use anything else. VWO is awesome and is always rolling out new features to their platform. They offer all of the features you will need for A/B, split URL, and multivariate testing. They even bundle heatmap/clickmap features. If you are considering a split test platform in your organization, don't look elsewhere.

We run some fairly complex tests with VWO and have always had excellent support from their team, when it comes to implementing custom solutions. The software is very easy to use, well within reasonable pricing, and is so much cheaper than the competition that it's a no-brainer.

Over the years, there have been a few changes to the site interface. Most of these have been great improvements, however, there have been some changes to the results dashboard that we just weren't a fan of. This isn't to say that it's bad - not by any means. It was just a personal preference.

We have solved the ability to find winning variations of landing pages for multiple different businesses with this software.

I love VWO! This software is excellent for split testing landing pages, which is extremely important for a new product launch where we want to optimize and get the most bang for our buck with the highest converting landing pages. This tool makes it easy to set up split tests and analyze.

Sometimes I question the split testing ability and have had multiple discussions with VWO about changes some things to make it better for the user / more optimized and haven't seen any changes go into effect.

Have a very good experience. After this tool we can do A/B testing more frequently, we can change text, image, change the size more frequently.

I am using this tool for last 3 years and have very good feedback on this. It's easy to use and help us to increase the conversion.

Conversion tracking options. It tracks only one visiter for a campaign i.e a visiter come 4 times via a campaign it tracks only one time.

I'm in charge of setting up tests on several websites and forms that belong to our company, I've been working with VWO since 2015 and it helped us to increase our revenue in the last years. VWO tools also helped us to find bugs on our pages through heatmaps for example, and help our sales team to measure our conversion rate on our forms and pages. In 4 years, we moved from few A/B test monthly scheduled to a full department and team dedicated to improve our User Experience using VWO as main tool.

There are a lot of functions and tools, some tests are very easy to set, the tool is quite easy to implement and results are quite accurate.

Sometimes it bugs on some pages, depending on page content and files included, making the results not accurate, and we cannot test to be 100% sure that's going to work.

We are using VWO to test changes to UI elements on our web, and we like it so far.

I've been using VWO for months now, and I like it very much. It is easy to set up and there are a lot of different testing options available (A/B, multivariate, split URL, etc.). Their editor is also very powerful and their support was always quick to response and was really helpful.

I don't like that the script you need to include on your site aren't hosted on some known CDN, which gives your site lower score on sites like WebPageTest. Also, their editor doesn't work well all the time - if you are making some big change on the page, you will sometimes see in the editor that your change is applied correctly, but in the preview the change isn't there - so you need to find a way how to insert it correctly.

Once setup it's a plug and play growth hacking tool that allows validation of theories.

Very hard to get running without a developer if you are using React.

In general good, it has worked so far for what we need, running into a couple of obstacles on the way but those obstacles would have been also present in other AB testing softwares.

Compared to other AB testing tools, VWO succeeds in a more reactive visual interface. Many core features are available with some of their starter plans, which only happens with more expensive plans on other AB testing softwares, like user segmentation and geo targeting.

Still expensive for the value it can provide, many of the really useful tests you can apply require complex behaviors which can be done through VWO but need technical knowledge.

Using VWO allows us to run sophisticated A/B tests for our clients and help them grow their business.

Using VWO you're able to run more sophisticated tests than other, free software. Support is helpful.

Some of the features in their reporting don't work very well, ie reports with old data and bad graphs for data over time. Seems to have more negative affects on site speed than other platforms.

We use VWO to AB test key pages on our website, and have achieved strong incremental success with the tool.

The BEST part about VWO is how quickly their Customer Service team responds on chat. I can get really quick feedback on an experiment I was planning to launch that same day.

Sometimes the features are confusing. Usually the service team or help pages clarify things easily.

We use it for heatmapping client's website and then making decisions on changing items above the fold + any possible CRO opportunities. For example, what are real people clicking and why? How can we then achieve the best outcome be it traffic or sales from the best possible path.

Easy to gather info on clicks and then make decision on internal links and where to put clickable elements for phone numbers, support links, even products.

A bit pricey considering the features however its probably the best heatmap tool i've used in my career so highly recommended. It CAN be difficult for clients to use and identify fixes via A/B split testing and the insights provided, however if a website has a marketing agency or CRO expert on board then it's a great tool.

I've been using VWO for almost 2 years and I'm pleased to see how much progress has been made so far. The learning curve is not very fast in my opinion, but once you get the hang of it nothing can stop you, you'll want to test, test and then test again. It integrates well with many services, the most important for me are MixPanel and Google Analytics. I haven't tried many other A/B testing tools, but I'm very pleased with VWO. Their Heatmaps are great too and give a lot of insights to help you decide on what to test next.

Lots of features, very complex and integrates with many other services.

The learning curve is a bit steep, but you'll get the hang of it.

Very positive with seemingly friendly passionate staff

VWO provides step by step interfaces making the implementation of A/B tests achievable to most levels of user

Occasionally alerts and warning were confusing to the user.
