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.

It is well suited for user experience and optimizing UI on a traditional website. It is not well suited when you need to optimize on campaigns from display as you run the risk of the native display networks blocking your ads from running.

Cons

Optimizely

  • I'd like to see more tools comparable to Visual Website Optimizer (VWO). Like user recordings and in page analytics.
  • If you have a dynamic area of information and edit it you pose a risk to making the page templates dynamic data static across the site. Pricing is a great example of this.

VWO

  • 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

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

Web interface is nearly always available. Javascript snippet (which actually runs the test) is distributed on a CDN for near-constant availability.

We have had some issues with screen flicker when loading experiment content. We had to dial back some of the creative changes to load smaller files.

Optimizely offers configuration options for different website setups - be sure to use a snippet that is consistent with your website design. For example, the Optimizely snippet can include full or trimmed copies of the jQuery Javascript library (which it needs to function), but this doesn't need to be enabled if you already have jQuery on your website.

Alternatives Considered

Optimizely

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.

VWO has more options, and a deeper engine for analysis. Unfortunately, I do wish they integrated better to pull data from GA as well
