Chose Optimizely Web Experimentation
We went with Optimizely over Lift because it was more flexible with creating variants outside of the "blocks" of content that Lift handles. So for instance, if you wanted to test an entirely new area of content you cannot do that with Lift. You can only test images/text in …

Drupal.org
Drupal is best suited for a dynamic website that needs customization and may need different user roles. It’s also great at learning to build a complex web application without knowing how to code a complex website. Although it can be implemented with minimal coding, knowing how to debug is almost necessary.

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
Drupal.org
  • Content Types... these are amazing. Whereas a more simplistic CMS like Wordpress will basically allow you to make posts and build pages, Drupal 8 gives you the ability to define different types of content that behave differently, and are served up differently in different areas of the website.
  • Extensibility... it scales, ohhhh does it scale. They've really figured out server-side caching, and it makes all the difference. Once a page has been cached, it's available instantly to all users worldwide; and when coupled with AWS, global redundancy and localization mean that no matter where you're accessing the site, it always loads fast and crisp.
  • Workflows... you have the ability to define very specific roles and/or user-based editorial workflows, allowing for as many touchpoints and reviews between content creation and publication as you'll require.

  • 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
Drupal.org
  • Security and new release notifications are a hassle as they happen too often
  • Allowing them to write PHP modules is a big advantage, but sometimes integrating them is a small challenge due to the version the developer is working on.
  • Steep learning curve, but worth it

  • 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.

The time and money invested into this platform were too great to discontinue it at this point. I'm sure it will be in use for a while. We have also spent time training many employees how to use it. All of these things add up to quite an investment in the product. Lastly, it basically fulfills what we need our intranet site to do.

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

Usability
Drupal.org
In comparison to other CMS alternatives out there, it is quite clean and maintainable when it comes to the small details. The general usability is great once you get to learn the details of it. The problem is that the onboarding process for new developers is a bit hard since there is no official, straight-forward documentation or video series.

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.

Reliability and Availability
Drupal.org
Drupal itself does not tend to have bugs that cause sporadic outages. When deployed on a well-configured LAMP stack, deployment and maintenance problems are minimal, and in general no exotic tuning or configuration is required. For highest uptime, putting a caching proxy like Varnish in front of Drupal (or a CDN that supports dynamic applications).

I would rate Optimizely Web Experimentation's availability as a 10 out of 10. The software is reliable and does not experience any application errors or unplanned outages. Additionally, the customer service and technical support teams are always available to help with any issues or questions.

Performance
Drupal.org
Drupal page loads can be slow, as a great many database calls may be required to generate a page. It is highly recommended to use caching systems, both built-in and external to lessen such database loads and improve performance. I haven't had any problems with behind-the-scenes integrations with external systems.

I would rate Optimizely Web Experimentation's performance as a 9 out of 10. Pages load quickly, reports are complete in a reasonable time frame, and the software does not slow down any other software or systems that it integrates with. Additionally, the customer service and technical support teams are always available to help with any issues or questions.

Support Rating
Drupal.org
As noted earlier, the support of the community can be rather variable, with some modules attracting more attraction and action in their issue queues, but overall, the development community for Drupal is second to none. It probably the single greatest aspect of being involved in this open-source project.

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.

In-Person Training
Drupal.org
I was part of the team that conducted the training. Our training was fine, but we could have been better informed on Drupal before we started providing it. If we did not have answers to tough questions, we had more technical staff we could consult with. We did provide hands-on practice time for the learners, which I would always recommend. That is where the best learning occurred.

Online Training
Drupal.org
The on-line training was not as ideal as the face-to-face training. It was done remotely and only allowed for the trainers to present information to the learners and demonstrate the platform online. There was not a good way to allow for the learners to practice, ask questions and have them answered all in the same session.

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).

Implementation Rating
Drupal.org
Plan ahead as much you can. You really need to know how to build what you want with the modules available to you, or that you might need to code yourself, in order to make the best use of Drupal. I recommend you analyze the most technically difficult workflows and other aspects of your implementation, and try building some test versions of those first. Get feedback from stakeholders early and often, because you can easily find yourself in a situation where your implementation does 90% of what you want, but, due to something you didn't plan for, foresee, or know about, there's no feasible way to get past the last 10%

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
Drupal.org
Drupal is community-backed making it more accessible and growing at a faster rate than Sitefinity which is a proprietary product built on .NET. Drupal is PHP-based using some but not all Symphony codebase. Updates for Drupal are frequent and so are feature adds.

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.

Scalability
Drupal.org
Drupal is well known to be scalable, although it requires solid knowledge of MySQL best practices, caching mechanisms, and other server-level best practices. I have never personally dealt with an especially large site, so I can speak well to the issues associated with Drupal scaling.

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.
