VWO

Good:
Simple tests like hiding and showing a button, text, etc.
Adding text onto the page
Changing the color of things
Split tests where the whole page can change

Bad:
Complicated tests regarding custom JavaScript that's run (there may be asynchronous actions happening in that script that we need the page blank for until those actions finish)
Want a smarter visual editor (e.g. we can change the layout and the test would still work, by class or id selectors)

Optimizely

I think Optimizely is a great fit for data-driven organizations that can afford a top-of-the-line testing tool. With Optimizely, you can be sure that performance and reliability will never be an issue with your site. Some split testing solutions can change the end-user experience, but I have had no issues with Optimizely. It is expensive, but provides tools for both engineers & non-engineering departments to implement, run & analyze tests.

Pros

  • You have the ability to have heatmaps recorded on any A/B or Split URL test, allowing you to investigate where users are concentrating most of their time within a control or variation.
  • VWO's ability to allow custom conversion tags to be placed and triggered on the website allows for more robust conversion tracking.
  • VWO's UI is very easy to use and navigate allowing users who are not familiar with coding the ability to test a website without the need of a developer in most cases.

  • 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.

Cons

  • Auto report on activity, unless I'm not aware of this feature my reports are created manually
  • Grouping tests and analysis into folders, I have a lot of tests and analysis running so scanning and finding the right item can be tricky
  • Usage reports, a weekly or monthly report emailed from the platform on our usage stats

  • I've had some bugs with the preview tool.
  • Their cost structure sucks for small businesses - they seem to be aiming for more medium to enterprise-sized customers who need scale.
  • Analytics are a bit weak as it applies to user retention.

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

Usability

Based on 1 answer
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.

Not a lot of documentation or best practice information. Interface is simple, but not very intuitive.

Optimizely is usually up 100% of the time. When there is downtime, it is usually very brief.

Optimizely refreshes automatically, so the speed and throughput is more than enough to use the product and analyze its data.

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.

On any questions or issues that we've had the Optimizely support staff has been very quick to help and really knowledgeable. Overall we couldn't be happier with the support we've received from their tech team

Implementation

VWO8.0
Based on 2 answers
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.

We use a third-party tagging tool that allows business users to insert JavaScript into pages. I don't holistically recommend this because it can slow page loads. It's best to implement directly on the page.Also, it can be difficult to carry the reporting variables over to Google Analytics and Crazy Egg.

Alternatives Considered

The key aspect in the decision to switch to VWO was the integration of all the features as a single unified resource and platform.The competitors are very good at what they do (did back then) but required moving insight and understanding from one platform to the other. With VWO this problem is not only solved but the recent change to VWOs focus on becoming a conversion optimisation platform has increased our capabilities significantly.We feel the product fits in perfectly with our human centred approach and has not only increased stake holder confidence in our thinking and actions but also helped us to become better at what we do as a team and as individuals in meeting the needs of our users.

We often use the Ion platform for building short-term marketing landing pages. It has a great interface for doing so, but is difficult to use as an A/B testing platform for already established traffic sources. It requires rerouting our traffic which is both inefficient and dangerous for us to do at the scale which we like to test. We're much more confident using Optimizely because we're simply modifying the existing experience rather than rerouting users to another website. And if something is not working right with a test, we can simply turn it off. I feel very safe deploying large-scale tests using Optimizely.
