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 …

If you want to set up a basic Not For Profit (NFP) Membership system and content base, Word Press is easier than Drupal. However, if you have specific needs that require a fair bit of customisation then Drupal is the best CRM available. If the webmaster is confident with PHP and SQL, Drupal allows a lot of creativity.

Optimizely
I think it can serve the whole spectrum of experiences from people who are just getting used to web experimentation. It's really easy to pick up and use. If you're more experienced then it works well because it just gets out of the way and lets you really focus on the experimentation side of things. So yeah, strongly recommend. I think it is well suited both to small businesses and large enterprises as well. I think it's got a really low barrier to entry. It's very easy to integrate on your website and get results quickly. Likewise, if you are a big business, it's incrementally adoptable, so you can start out with one component of optimizing and you can build there and start to build in things like data CMS to augment experimentation as well. So it's got a really strong a pathway to grow your MarTech platform if you're a small company or a big company.

Cons
Open Source
  • This is not an easy CMS to work with if you don't have a good understanding of website development. It isn't "plug-and-play" like Wordpress or Shopify.
  • Over time, doing major updates to the system can be taxing, especially if you aren't well-versed enough in doing system updates in line with your "child" theme and code.
  • The CMS can become somewhat cumbersome with server resources if not carefully optimized while you build and customize it to your liking.

  • 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
Open Source
As a team, we found Drupal to be highly customizable and flexible, allowing our development team to go to great lengths to develop desired functionalities. It can be used as a solution for all types of web projects. It comes with a robust admin interface that provides greater flexibility once the user gets acquainted with the system.

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
Open Source
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
Open Source
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
Open Source
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.

In-Person Training
Open Source
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
Open Source
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

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.

Drupal can be more complex to learn, but it offers a much wider range of applications. Drupal’s front and backend can be customized from design to functionality to allow for a wide range of uses. If someone wants to create something more complex than a simple site or blog, Drupal can be an amazing asset to have at hand.

The ability to do A/B testing in Optimizely along with the associated statistical modelling and audience segmentation means it is a much better solution than using something like Google Analytics were a lot more effort is required to identify and isolate the specific data you need to confidently make changes

Scalability

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.

We can use it flexibly across lines of business and have it in use across two departments. We have different use cases and slightly different outcomes, but can unify our results based on impact to the bottom line. Finally, we can generate value from anywhere in the org for any stakeholders as needed.

  • Given the endless possibilities that Drupal can have, we tend to have great support going on when we get a website launched
  • It has become much much faster and easier for us to launch a new project due to reusability
  • Configuration management in Drupal helps greatly with CI/CD, saves us costs

  • 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.
