Contentful is well suited for folks who want a simple, clean, easy-to-use interface for a JAVASCRIPT website. If you do not want a javascript website you should look [elsewhere].

Optimizely
I have found Optimizely has been really useful to run some quick experiments to validate the approach to changes to the website, exploring multiple options simultaneously to save time and effort prior to making more permanent changes with our development team. The biggest challenge has been ensure ideas from the wider business have all the necessary criteria to make them a worthwhile experiment. Encouraging stakeholders to create a proper hypothesis for each experiment has helped focus the minds on the outcomes we're expecting. This also makes the analysis easier once we've concluded a test

Pros
Contentful
  • Clean, modern interface (not clunky and outdated, like WordPress)
  • High degree of flexibility (I can structure data any way my clients need)
  • Enables headless frontend (i.e. I can build any frontend I want without having to change my CMS)

  • The Platform contains drag-and-drop editor options for creating variations, which ease the A/B tests process, as it does not require any coding or development resources.
  • Establishing it is so simple that even a non-technical person can do it perfectly.
  • It provides real-time results and analytics with robust dashboard access through which you can quickly analyze how different variations perform. With this, your team can easily make data-driven decisions Fastly.

Cons
Contentful
  • The new Contentful "branches" feature looked promising (it appears to mirror a git-like repository) but it requires the CLI, which isn't necessarily practical for teams that aren't current CLI users. It would be nice if the management of this feature were available via the UI (without that it causes more confusion than anything).
  • The Contentful data modeling method makes for a bit of an awkward SDK developer experience in some strongly typed languages like Java. Most things that you might need can be accomplished, but it feels like the experience could be smoother.
  • It would be nice if there were a way to migrate data between spaces (e.g. from your staging space to production).

  • JavaScript is hard to implement sometimes especially for JQuery elements
  • ROI reporting should be part of the overall experimentation reporting
  • CMP integration: where we can easily show status of test on the HPT request
  • CMS integration
  • More widgets like social proof banners, etc.

I rated this question because at this stage, Optimizely does most everything we need so I don't foresee a need to migrate to a new tool. We have the infrastructure already in place and it is a sizeable lift to pivot to another tool with no guarantee that it will work as good or even better than Optimizely

Optimizely
Optimizely Web Experimentation's visual editor is handy for non-technical or quick iterative testing. When it comes to content changes it's as easy as going into wordpress, clicking around, and then seeing your changes live--what you see is what you get. The preview and approval process for sharing built experiments is also handy for sharing experiments across teams for QA purposes or otherwise.

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.

Easy to use and much more organized as a single platform versus multi. The layout is clean and easy to read and we don’t have to worry about certain users safe guarding data or content then losing it when they leave the company. It’s a one stop shop for imagery

None of them have a best in class stats engine and live within an ecosystem of marketing technology products the way that Optimizely does, so the scalability of using any one of those tools is limited as compared to using Optimizely Web Experimentation.

Optimizely
It's incredibly flexible and adapts well to organizations of all sizes, whether you’re running a single site or managing multiple departments and platforms. The ability to deploy experiments seamlessly across different environments is a huge plus, especially for growing businesses. While it’s highly scalable, the last point would depend on the right team leveraging its full potential.

  • We're able to share definitive annualized revenue projections with our team, showing what would happen if we put a test into Production
  • Showing the results of a test on a new page or feature prior to full implementation on a site saves developer time (if a test proves the new element doesn't deliver a significant improvement.
  • Making a change via the WYSIWYG interface allows us to see multiple changes without developer intervention.
