EU Emin U. Technical Lead Mid-Market (51-1000 emp.) 4/28/2026 "Effortless A/B Testing with Easy Setup" 4/5 What do you like best about Optimizely Web Experimentation? I use Optimizely Web Experimentation for A/B testing. I found it was easy to integrate, and the web interface is really self-intuitive. The APIs are well designed, which saves development time and lets us launch experiments fast. The automatic customer distinction and data management features are excellent, providing valuable insights. The intuitive interface also allows non-technical team members to set up and monitor tests independently, significantly speeding up our decision-making process. Plus, the integration with shared libraries was straightforward, only requiring adding a dependency and two lines of code for each project. Review collected by and hosted on G2.com. What do you dislike about Optimizely Web Experimentation? The reporting and analytic dashboards could be more detailed and customizable. More granular segmentation options in reports, like filtering results by device, location, user behavior, type etc. Exporting raw data could be more easy. Review collected by and hosted on G2.com. What problems is Optimizely Web Experimentation solving and how is that benefiting you? Optimizely Web Experimentation lets us test features on small groups to see if they attract or repel customers, saving development time with well-designed APIs and automatic customer distinctions. Its intuitive interface allows non-technical team members to set up tests independently, speeding up decision-making. Review collected by and hosted on G2.com.

Digital Marketing Specialist 12/18/2025 "User-Friendly with Valuable Insights" 4/5 What do you like best about Optimizely Web Experimentation? I like that Optimizely Web Experimentation is user-friendly and easy to set up even for a non-technical person. It's great that it provides real data instead of relying on individual and biased opinions. The initial setup was very easy and doesn't require much technical intervention. Review collected by and hosted on G2.com. What do you dislike about Optimizely Web Experimentation? I find that it could provide more data on users to help analyze the type of users attracted to specific landing pages. Review collected by and hosted on G2.com.

Website Optimisation Manager Enterprise (\> 1000 emp.) 3/5/2025 "Optimizely's Web Experimentation is a great tool for experimenters" 4/5 What do you like best about Optimizely Web Experimentation? Optimizely is the tool I use at work most of the time. I really like how intuitive and user-friendly it is. I can easily build and manage my experiments. It is very comprehensive in terms of the functionality it offers and can probably solve most use cases. They have extensive information for marketers and developers available in their help centre. Customer support has always been helpful and prompt to answer our questions. Additionally, Optimizely regularly releases new updates to make it even easier to use and manage your experimentation programme. Review collected by and hosted on G2.com. What do you dislike about Optimizely Web Experimentation? It takes a bit of time to learn the tool and all its ins and outs, but once you do, you realise how straightforward it is, although it can be quite overwhelming at first. Another thing to note is that it's quite a pricey solution, which is not surprising, given that it's constantly marketed as best in class by Gartner. Review collected by and hosted on G2.com. What problems is Optimizely Web Experimentation solving and how is that benefiting you? Optimizely helps us to improve our user journeys and customer experience on the website.

I like that the brand is reputable and the platform is useful for basic experimentation. The UI makes the platform easy to use and understand. I also have had little to no issues with something not working. Review collected by and hosted on G2.com. What do you dislike about Optimizely Web Experimentation? I think some small things about the UI can be improved. There is not much that I dislike but more of things that I think can be improved for better user experience. Review collected by and hosted on G2.com. What problems is Optimizely Web Experimentation solving and how is that benefiting you? It is allowing us to split traffic for several AB tests at a large volume. We do not rely on the metrics reporting as much, because we use our own BQ data. The main value of optimizley for us is splitting traffic through an experiment ID. That is helping us identify winning tests and rolling them out at scale, helping increase the incremental revenue for the business. Review collected by and hosted on G2.com.

Mid-Market (51-1000 emp.) 3/5/2025 "Powerful tool that we need to use to step our CRM and Martech flows to the next level" 4/5 What do you like best about Optimizely Web Experimentation? The ability for non-technical users to execute experiments on our homepage and iterate more quickly than is currently possible by our teams. Also, the highlighting of how we can potentially use AI to supercharge this side of personalisation and content experimentation for our business. Integrating and implementing has been easy throughout. Review collected by and hosted on G2.com. What do you dislike about Optimizely Web Experimentation? In our case it's not necessarily a dislike about the tool, I think it's more about getting the right teams to know what features are offered. I think experimentation at our organisation is still seen as something owned completely by data, but web experimentation democratizes that, and should therefore be adopted by other teams like Martech and Marketing to a deeper extent than is currently done. Review collected by and hosted on G2.com. What problems is Optimizely Web Experimentation solving and how is that benefiting you? Faster iteration over content-based experiments for our website homepage. However again, we're not getting as much as we should out of this part of the software.

Optimizely is a great A/B & personalisation tool. It considers usage of the tool thoughtfully, and manages to balance flexibility and customisation, with simplicity. When things don't quite go well, or are hard to find, their support is second to none. Someone usually responds to a ticket within a day or two. Review collected by and hosted on G2.com. What do you dislike about Optimizely Web Experimentation? We have had some issues with the configuration of SSO, along with our system. There is an assumption that email is the login ID for SSO. There is however a workaround for this. Another key thing missing, especially after having used a competitor's tool, is the ability to prioritise multiple personalisation activities within the same page. Review collected by and hosted on G2.com. What problems is Optimizely Web Experimentation solving and how is that benefiting you? Allows us to experiment and personalise to make the user experience on our website simpler (hopefully). Review collected by and hosted on G2.com.

Head of Product Mid-Market (51-1000 emp.) 3/25/2025 "A great platform for validating hypothesises and Conversion Rate Optimization" 4/5 What do you like best about Optimizely Web Experimentation? Both the speed with which you can undertake experiements and changes, meaning you can validate lots of hypothesises in a short space of time, and the ability to have reassuances on the data impacts (and calculation of statisitcal significance). The WYSIWYG editor significant helps team members with low technical accumen. Have had great help with Optimizelys customer support team. Review collected by and hosted on G2.com. What do you dislike about Optimizely Web Experimentation? Dependent on the change, your tech stack needs to be able to work with Optimizely. Some of the tests that you feel could easily be accomplished in Optimizely Web, prove to be more difficult, and there is a reasonable learning curve to understand what can be feasibly achieve in the platform and what cannot be.

Strategic Digital Marketing Manager Mid-Market (51-1000 emp.) 4/1/2025 "Can run just about any experiment I throw at it" 4/5 What do you like best about Optimizely Web Experimentation? I've been using Optimizely Web Experimentation for a couple of years. It can handle just about any experiment we throw at it, has a robust reporting engine, they introduce new features at a fast rate and the performance is good. It's an efficient platform to use as well. The customer support team has also been very helpful whenever we've needed them. Review collected by and hosted on G2.com. What do you dislike about Optimizely Web Experimentation? While mostly easy to use, you do need a basic understanding of CSS selectors and the DOM. Without that base level you'll find it a frustrating experience trying to select the right element to change or measure. Review collected by and hosted on G2.com.

Trainee Personalisation Manager Enterprise (\> 1000 emp.) 3/25/2025 "Very good tool" 4/5 What do you like best about Optimizely Web Experimentation? The upsides are that you can easily put experiments live. I do not have CRO experience and putting these experiments live was very straightforward. The tracking of results and the statistical significance is also very clear. We like how we can also test into different pages on site not just as a whole which a different competitor we used to use did which limited us Review collected by and hosted on G2.com. What do you dislike about Optimizely Web Experimentation? One thing I’ve found is that I can’t check revenue per visitor in the dashboard only revenue per session which limits our reporting and need to go to GA for this.

There are a wide range of tests that I can run using the platform: A/B, A/B/n, multivariate, multi-arm bandit and 'stats accelerators'. The trigger options allow me to quite easily target discreet customer segments by device type, or browser type, or by another specific behaviour. I've also done tests using custom JavaScript to suppress tests for more sensitive customer segments. I like the reporting dashboard, which is good for conducting dip checks on how specific tests are performing across different browser and device types - and for seeing how a test is performing over time. I also like the fact I can set a test to roll out to 5% of traffic, conduct a few post-live checks and then quickly duplicate the test and roll it out to 100% of eligible traffic. Customer support tickets are via email and I usually receive a response within a few hours, which is good. Review collected by and hosted on G2.com. What do you dislike about Optimizely Web Experimentation? The visual page building tool is quite basic and could do with a refresh. It means that you more or less have to know HTML and CSS to build your own simple tests, and JavaScript for anything more complicated. Many CRO practitioners will use Bayesian probability alongside Frequentist statistics if traffic volumes are smaller for specific tests. The reporting dashboard defaults to statistical significance - so Bayesian needs inclusion. Review collected by and hosted on G2.com. What problems is Optimizely Web Experimentation solving and how is that benefiting you? My company wants more customers to convert using digital channels. To do this, we need to be able to reliably test different designs and features to understand what works best from a customer perspective. Optimizely gives us a solid platform to do this, which we also integrates reasonably with our data warehouse and analytics tools. This means we can tag customer segments using Optimizely and then clean the data, and be able to make more confident business decisions about what to implement.
