    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.

    Zendesk is good for small teams where work is not passed along to internal teams or situations where escalations lead to further customer interactions and no further oversight is needed. It is weak as a product for larger and medium-sized companies, where processes are in place that are not aligned with its workflow, as it is a very rigid tool.

    Pros
    Optimizely
    • 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.

    • Merging of the tickets with similar issues, it is easy to avoid confusion
    • Al global team somehow gets connected with different ways like Slack, with the Zendesk Suite which is so easier to highlight & the issue quickly
    • The best thing is that this tool gives you to send the message via chat-, email, call through the one single platform
    • Now AI has been added so it works good

    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.

    • Is there a way for AEs and CSMs to be informed in a weekly summary of all their accounts and any tickets? Example: Disney submitted a ticket on XYZ. Google has an urgent issue on X still unresolved.
    • Is there a way for CSMs or AEs to have a Dashboard that's specific to their accounts instead of seeing all the tickets in the queue that are not relevant to them?

    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

    Zendesk is an amazing tool for communicating with your customers easily. The communication tickets from sellers to us or from us to sellers are stored, and there are statuses used to make communication easy. We have internal conversations between departments, linked with useful software such as Zingtree, Talkdesk, and Webs.

    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.

    Pros: The agent interface is sleek, contemporary, and relatively easy to learn compared to many other enterprise tools. For common tasks, admins are given point-and-click options- adding fields, modifying workflows, constructing macros. The knowledge base (Guide) editor is easy to use for non-developers. Drawbacks: Once you move past the initial things - complex automations, reporting/analytics in Explore, and/or customizations integrating the API, it requires much more advanced training to use successfully. Navigating between the different modules (Support, Explore, Chat, Guide) can feel very disconnected; often you are reminded that it really is a "suite" of products brought together -not really one unified platform. If you're using multiple brands managing simultaneous support tickets, or heavily customizing workflows to meet your brand, you may run into a bit of struggle with usability. So: it's a lot more user friendly than the palaces (Salesforce Service Cloud, ServiceNow), but is not used as quickly or with as much streamlined flow as a product made for a small shop. So if you are looking for a great balance, this is a good option if you are a net new organization or an organization on their way to scaling from 15 - 50 employee. Expect some elbow grease from the admin team once learning, adapting, and working efficiently once you move past the basics with your support tickets and initial customizations.

    We rarely need to contact their support team, but when we do they are responsive. However there have been notable times when communication between myself and the support rep was challenging despite me providing clear explanation of the issue, screenshots, and a thorough explanation of the goal we hope to achieve. It took several back and forth attempt, on a few occasions, to get resolution on an otherwise simple request

    Online Training

    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).

    Zendesk has tons of available material for training - videos, webinars, articles, etc. The only reason this is not a 10 is because it can be hard to figure out how to navigate to these things and find what you are looking for.

    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.

    I was very satisfied. They have a free trial for 30 days and I recommend you do that and use it. It is very easy to get started with the basics and the build on over time.

    The only thing technically complex was single sign-on and integration to Salesforce.com required some tweaks – otherwise setting up system was very easy

    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

    At the time of evaluation, Dynamics had extremely limited knowledge and support capabilities. The UI is clunky, and reporting requires a deep understanding of the underlying data structure. Ongoing maintenance was costly and didn't provide a positive ROI in any sense of the term.

    • 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.

    • More than anything, provided a boost to our perceived professionalism. The portal is a massive improvement on email only support.
    • Workflow optimization via macros and automations has enhanced response times and raise our 'first call resolution' metric.
    • Speaking of metrics; having them at all! Before Zendesk Suite we were email only so had no insight into agent and vendor performance.
