    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.

    Since the purpose in my case is to build a small professional looking site to present project outcomes and other research, I can create custom fields and design experimentations. Webflow builds sites that are super professional, with many amazing templates that don't look cheap. Additionally, I can test responsive layouts. Apart from this, I used 1-2 static pages to illustrate key findings for example what a multilingual site could look like with screenshots without needing CMS in free version, which are all the valuable skills to acquire. Compared to WordPress, Webflow is expensive with limited free features, although it has really cool additional features that will make the site I build stand out.

    • Saves time- because I don't have to do double entry of content.
    • It saves money. I like that it is an all-in-one system, so I don't have to host elsewhere.
    • Flexibility - Webflow provides me with a lot of flexibility in my webpage design, allowing me to adjust pages as needed, depending on the content types.

    Cons
    Optimizely
    • 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.

    • Brand recognition is still behind WordPress, which can make it a challenging sell for clients looking to play it safe in their CMS decision.
    • The CMS is ideal for smaller datasets, but higher content sites introduce some minor challenges.
    • Alignment between designers and developers is key prior to implementation. The flexibility of the platform requires careful planning to avoid over-engineering.

    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
    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.

    Webflow is very easy for a beginner to get started with and achieve good results, but to achieve an expert level of understanding requires experience and some web development knowledge. HTML5, CSS3 and JavaScript knowledge aren't required to use Webflow, but an expert will know BEM class naming patterns, be able to create reusable elements and design systems, and add 3rd party integrations that require custom code.

    In my experience, their customer service is an absolute joke, I tried reaching out to them they took forever. I had to keep following up with them as if they never received it in the first place. It’s a new platform, so guidance is needed. Tried the university they offer, in my opinion, it is completely useless, I would just completely move on from this website.

    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.

    In my opinion, it is horrible, the rendering takes forever. I have the newest MacBook and the platform will still lag and slow down on me. I’m not a developer, I am a designer which makes it worst because I am using the features they are providing not extra coding features. In my opinion, it is a horrible platform really, stay away.

    I haven't had to engage them from a support perspective; however, there is a considerable user community for tips/ideas/troubleshooting and the like. I believe the Pro plan supports additional resources but we didn't find that the cost justified the outcome. Overall the need for support has been relatively minor.

    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.

    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

    A lot more design control and easier to create a custom site, and then also to scale that site going forward. There's a lot about WordPress I miss, though, when it comes to managing a blog—user permissions, SEO control, edit HTML version of posts.

    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.

    I feel it doesn’t perform the way it’s supposed to and it doesn’t have any beneficial factors to it. In my opinion, there is no reason to use a platform like this when Wix and Shopify, and WordPress exist. I believe Webflow is a platform that shouldn’t exist and it’s only popular because of the hype it received. I tried it and hate it completely.

    Return on Investment
    Optimizely
    • 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.
