Contentful

Coming from WordPress, Contentful feels like content management as it should be. There's no clutter to get rid of, you can simply start building from scratch, and the end product is perfectly tailored to your or your clients needs.

Optimizely

Optimizely is a great A/B testing tool for any size business. The Optimizely platform democratizes A/B testing through a simple interface, excellent training tools, easy implementation and low dependence on IT resources. Utilizing Optimizely I've been able to run robust experimentation programs with a variety of resources (acting as a 1-person team with limited access to IT resources as well as managing a team with high access to resources). Additionally, Optimizely is well-priced and positioned to be affordable for a variety of business sizes.

Pros

Contentful

  • Contentful provides organized, flexible data models with support for a variety of data types and content editors (e.g. WYSIWYGs, form fields, raw text areas).
  • Contentful has great built-in versioning features with history and draft states so it's easy to make updates and revert when needed.
  • Contentful has an intuitive user interface and good support for multiple spaces (which can be helpful for companies that need separate projects for dev/staging/production).
Eric Mason | TrustRadius Reviewer

Optimizely

  • 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

Contentful

  • Preview of changes prior to publishing
  • The ability to use a spell check plug-in when working on content (it doesn't work well with Grammarly)
Nathaly Sierra | TrustRadius Reviewer

Optimizely

  • Actual creation of an A/B test is confusing and difficult (like the differences between Pages vs URLs etc.).
  • Setting up a URL Redirect Experiment is so convoluted it seems like it's not even a feature Optimizely wants you to use. Instead, it's like I'm tricking Optimizely into alternating between 2 URLs. That really needs to be cleaned up as it would be very helpful.

Because it's an incredible and essential tool for my line of work as a conversion optimization specialist. Really couldn't do my job nearly as effectively without it. It's paid for itself many times over and I feel like I'm only beginning to unlock the tools potential.

Without a doubt, after 8 years using various different testing tools, Optimizely is by far the easiest to use. Feedback from developers and more technical teams has always been positive, mostly due to the code editor allowing for easy implementation along with the creation of advanced audience segments using advanced javascript. For business users and non-technical people, the wysiwig editor allows for smaller changes to be made quickly whilst somewhat educating the user on the types of code changes that are being made.

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

They always are quick to respond, and are so friendly and helpful. They always answer the phone right away. And [they are] always willing to not only help you with your problem, but if you need ideas they have suggestions as well.

The tool itself is not very difficult to use so training was not very useful in my opinion. It did not also account for success events more complex than a click (which my company being ecommerce is looking to examine more than a mere click).

In retrospect:- I think I should have stressed more demo's / workshopping with the Optimizely team at the start. I felt too confident during demo stages, and when came time to actually start, I was a bit lost. (The answer is likely I should have had them on-hand for our first install.. they offered but I thought I was OK.)- Really getting an understanding / asking them prior to install of how to make it really work for checkout pages / one that uses dynamic content or user interaction to determine what the UI does. Could have saved some time by addressing this at the beginning, as some things we needed to create on our site for Optimizely to "use" as a trigger for the variation test.- Having a number of planned/hoped-for tests already in-hand before working with Optimizely team. Sharing those thoughts with them would likely have started conversations on additional things we needed to do to make them work (rather than figuring that out during the actual builds). Since I had development time available, I could have added more things to the baseline installation since my developers were already "looking under the hood" of the site.

Alternatives Considered

Contentful

Contentful offers a great deal of features for a relatively low price. This is what ended up persuading us to purchase it. We also gathered that this was one of the more well-rated products out there, which was encouraging. It definitely stacks up well against its competitors.
Nathan Richardson | TrustRadius Reviewer

Optimizely

I think that Optimizely is more user-friendly than Adobe and Monetate, for example - Adobe is really suited for people with deep pockets and a distinct technical acumen that may not be suitable for a small business. Montetate is not user-friendly - even for seasoned marketers. Apptemize is a pretty great product but they killed their free product. Like Optimzely, they seem to be shooting for enterprise-level clients.

It's all you need to design, install, analyze and measure simple tests with Optimizely. When test complexity increases, it becomes necessary to integrate third party analytics tools to perform more detailed analysis such as additional details like page views, average time spent on each page, and bounce rates by variation. Optimizely has very straightforward integrations, so integration with analytics is straightforward.
