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.
