Optimizely is a website optimization platform, providing A/B and multivariate testing. It enables users with and without technical expertise to make dynamic changes to their websites, test the variations to live traffic and gather immediate results.https://media.trustradius.com/product-logos/PJ/xR/9ITXLXGFX53G.PNGA required tool in any online marketer's toolbox.We use Optimizely in the marketing department to tweak and modify our paid search landing pages for maximum conversion. It gives us the ability to see how people interact with our pages and see which assets are driving value. The ability to split into multiple variations gives us the flexibility we need to test on the fly.,Optimizely's user interface is simple enough to use and understand quickly. You can select elements to track by just clicking on them. Optimizely's goals are easy to set up. Optimizely has a lot of great resources that help educate it's users.,The way goal targeting works is a bit confusing. The snippet verification never seems to detect our snippet. Regardless, the tests run fine and are tracked properly.,8,Lead conversion has steadily grown with our iterative testing. We've seen what types of things leads are looking for through optimizely.,Crazy Egg,10Optimizely is a must-have resource for any business that has a strong investment in the digital atmosphere.We began using Optimizely in an effort to capture insights while continuing to develop our website with customers in mind. From I.T., Sales, and Marketing our business has become very in-tune with creating a more simplified approach to displaying products and information, making it easier for the customers to find the parts they need and fix their machines quickly.,A/B testing on-the-fly to measure multiple metrics efficiently. Easy implementation and reporting features makes beginning tests and tracking progress easy. A large database of resources to help those new to optimization set up their tests and expand their ability to use the software effectively.,The ability to group certain tests together and allow for one report would be nice. We test multiple pages at a time, and having the ability to look at one screen to track results would be a big win for us. Some delicate html or javascript does break when using Optimizely. So large-scale changes may be best handled by using redirects instead of the on-page tools.,9,We have been able to lift conversion rates and revenue over time since implementing Optimizely. Making decisions for website development has been made easier by knowing what is positively or negatively affecting customer experiences. Getting a better understanding of how customers interact with certain pages on our website has given us the tools to move forward with other website goals.,Visual Website Optimizer,10My go-to tool for a/b testingWe selected Optimizely as our main tool for a/b testing after trying Google Analytics Content Experiments and Visual Website Optimizer. It's easy to use by everyone in the Marketing team so they can quickly test their ideas.,It's very easy to use. Their support is excellent. On the technical side you add the code to the site only once and you don't have to create a new page for variation.,With bigger sites you can reach the monthly visitors limit pretty quickly.,10,We managed to increase our trial conversions.,Google Content Experiments,Visual Website Optimizer,10Easy and quick to setup and useI've used Optimizely at my previous employer and when I switched to my current employer two years ago I brought Optimizely over here as well. We brought it on mainly for frontend website testing - and have been very pleased with it! It's super easy to use - you just embed some code (same code for sitewide pages) and then go into the Optimizely tool and select which elements you want to switch out and what you'd like to switch out with. Super simple. Only basic HTML/CSS knowledge needed. They do have a WYSIWYG easy visual changer you can use to make changes to be tested, though with our site which is custom built in-house it doesn't give us the flexibility we need so we do need to know some basic HTML/CSS. I'd definitely recommend it!,Ease of use - point and click WYSIWYG editor if you like that method. Easy to setup - put code on all pages sitewide (with a simple include statement in the header) and you're ready to roll! Great price - compared to competing products you really can't beat the price!,Their code snippet (Javascript) that they run on the page has been HUGE - it keeps paused test code in the on page script... which gets unwieldy after you run lots of tests. Thankfully, Optimizely just announced that they're fixing this issue to lighten the code on the frontend. Haven't tried it yet though to see how well it works.,9,We've improved our customers site use experience considerably. By improving customer site use experience it's helped revenue as well.,Adobe Test and Target,5Optimizely helped us OptimizeWe use Optimizely to make simple A/B-tests on landing pages, product pages etc.,Great ease of use, also for users with little or no programming skills. So far, it has been possible to run most of the tests we've needed even though we could not forsee what the future would bring when we first decided to go with Optimizely rather than the alternatives. Fast and competent email support, ok knowledge base.,Segmented results are only available in the most expensive plan. WYSIWYG editor is not suitable to build completely new pages. Copy-Paste function missing in editor. Only one custom variable available for revenue, lead values etc.,8,Many minor improvements that had great impact. Sometimes the tests we've made showed that adding / removing even the smallest pieces of content made differences worth millions. The ability to argue against HIPPO's (highest paid persons oppinion) with qualified, accurate and indesputable data is always worth a lot. The ROI depends heavily on how much you use it and on your site, but to us, it has paid back manyfold.,Visual Website Optimizer,Adobe Test and Target,10You Need to Be Optimizing Your Website, and Optimizely is the Ideal Soltuion for Most CompaniesWe are currently using Optimizely for both multivariate and A/B testing our websites, and we have received some pretty big incremental wins. Optimizely is easy to use and affordable. I like that there are several tools to help cross-browser check the edits you make on the interface. There are more advanced options available, but for most companies, Optimizely should certainly be enough. (Especially since Google does not offer multivariate testing these days).,Multivariate Testing: Run many variation tests Easy to use: Can design changes within the interface and after the first install, no additional code is needed Cross-Browser Testing: Allows you to test the changes in many browsers,Advanced options: I have had some issues configuring very advanced tests,9,Increased lead conversion Increased sales conversion (Increase ROI of all other marketing campaigns),Google Content Experiments,Adobe Test and Target,9Brilliant product let down by speed issuesWhen I used Optimizely - and I still will be in future - it was just me at Engaging Networks who used it. We used it to help clients decide which of their fundraising pages converted better.,It's so easy to set up a split test even if you have no coding knowledge It's good at tracking the results You can do multivariate testing Great interface,The main problem I had with Optimizely is that it caused test pages to render much more slowly than pages where the Optimizely embed code wasn't being used. Given how important speed is to the web and to ROI, this is a serious problem, and as a result I try to use Optimizely as little as possible.,6,Ability to write better case studies for clients due to the learning we now have about what works and what doesn't for online fundraising.,,5Integral part of our approach to marketing & onboarding.We use Optimizely whenever we make a change to our www website or onboarding process. It allows us to see the true impact of our design, marketing, and onboarding decisions. This has been interesting because some things have no long-term impact and others do, yet they aren't always the pieces we'd imagine. (We also use KISSmetrics for long-term tracking, and tie it all together with Segment.io.),Easy to use. Whether we're doing redirects or changing the DOM, it's pretty easy to figure out. Segment.io integration. Makes it trivially easy to implement and to reuse our existing events and goals. Reasonable pricing.,Tests that involve redirects can be a little awkward to setup and modify. No serverside tracking for longer-term events. (We use KISSmetrics for this though, and Optimizely connects nicely with that.),10,Higher conversion rate from visitor to signup to paying customer.,Google Analytics,10A visual designer's point of viewI work as a product designer and Optimizely is being used by our team to test out growth and customer acquisition projects. Optimizely helps us quickly design, develop and launch temporary tests on our website without having to engage all of our engineering resources, or disrupting the core features of our sight. It is also invaluable in terms of gathering user data based on our tests.,Great user interface that I was able to learn quickly. I was up and running within one hour. Optimizely creates temporary interactive layers, almost like "stickers" that can be placed, replaced and adjusted without major repercussions sitewide. Since we started using Optimizely, we are able to take more creative risks and see what helps reach our customers and what doesn't. As a designer, it is great to get in there and make minor tweaks to alignment and typography without having to take up a developer's time.,It would be wonderful to see the design WSYISWG interface expanded. Right now it works well, but is somewhat limited.,9,Definitely increased employee efficiency and better use of in-house resources Our customer base is growing every day based on the learnings we have gotten from our testing, thanks to Optimizely! We are able to continue experimenting with new creative ways to introduce users to our product.,,9If you have $ to spend, Optimizely A/B testing lifts conversion ratesWe use Optimizely across Clever Zebo for A/B testing, both for us and clients.,User experience is simple Feature-rich tool As a marketer you can set up your site for A/B testing and rarely need a developer's help Great customer support.,Can't think of a bad thing about it. Great tool. Maybe it's a bit pricey.,10,A/B tests have shown big conversion rate improvements for our clients. We've also seen big lifts in engagement.,Google Content Experiments,Visual Website Optimizer,10Optimizely ReviewOptimizely is being used by our marketing department and product/service department. We use the tool to conduct multivariate tests in order to improve conversion rates and the overall customer experience. Improving conversion rate ultimately ties to the success of the entire business, so the Optimizely tool is great in that employees without technical experience can easily create and optimize multivariate tests.,Ability to easily insert texts and images into web pages Allowing for detailed targeting options Optimizing desktop and mobile pages separately,Page load time Including anchor text Creation of new pages,7,Increase conversion rates Increased number of tests conducted Improved customer experience,Kenshoo Search,8Optimizely, a solid conversion and optimization toolOptimizely is used by our Digital Strategy team to manage not only our own web properties but those of our clients as well. Optimizely provides a lightweight solution to our optimization needs and makes it easy to apply solid strategies across all of our products. The product is easy to use, easy to learn and packed full of powerful solutions.,A/B Testing Code optimization Experiment with changes before going live Conversion tracking,Interface can be confusing for some Pricing,8,Enhanced ability to track custom conversions Easier to target hot spots on pages and optimize for them,UnBounce,8Optimizely: Solid A/B testing solutionOur client has been happy with the tools. The set-up and execution of experiments is relatively simple. It has been used extensively to test content, banners, sign-ups, and product locations.,The design needs of the client has required a lot of developer experience to create test content and integration with site functionality that's not 'out of the box'.,In my current role I am not measuring the product performance.,8,7,4,1,A/B & Multivariate testing on a retail website.,,Professional services company,7,Self-taught,Product training is always preferred over self-training. This helps to have multiple people with a similar product skill-set available to assist with projects and train others to the same level of expertise.,There has been a lot of experiment integration with site functionality like email sign up, add-to-cart, product display grids/positions, custom espots with additional functionality, etc.,No,8,5,9,7,Adobe Analytics (Site Catalyst) Adobe Dynamic Tag Manager,Many of our clients also use eBay Enterprise Attribution (formerly ClearSaleing).,,N/AOptimizely - The A/B Testing Tool to Rule them AllThe best thing about Optimizely is how quick and easy it is to use. With one line of JavaScript, you are able to install Optimizely on your website and start testing. Design and dev work is no longer a bottleneck to start testing. Simply open up the Optimizely dashboard and use their WYSIWYG editor (What you see is what you get) to start changing content. If you are lucky enough to have design and dev resources, then you can simply create a redirect test that points to your new design.,The product excels at creating tests quickly and getting up and running. Results are also easy to read and no dev experience is necessary to get started.,We have been able to lift our conversion rates by 30% across various content assets since running Optimizely. This has, of course, had an effect on increasing signups and increasing revenue.,10,10,6,2,Optimizely is used to A/B test our entire website and marketing landing pages. By creating different types of content around different products and features, across different sources of traffic, we are able to test various messaging to find the 'optimal' one that works for a specific segment.,Implemented in-house,10,Self-taught,Optimizely has a lot of documentation on how to use their product. Reading these docs and experimenting with the product is the best way to get acquainted.,We added a custom event to Optimizely, to track a signup event from our application, in addition to Optimizely page view and click goals.,Yes,10,8,10,9,We have integrated Optimizely with CrazyEgg and Mixpanel.,Optimizely is very worth it for the priceSite optimization is one of the most critical activities of a product manager. It allows you to test different experiences against each other to learn which is most effective for customers. Optimizely allows you to do this very easily. It may not be as robust as something like Adobe Test & Target, however for the price it's beyond worth it.,One thing it does not appear to have is the ability to segment an A/B test into different customer demographics. If it's there, then it's hard to find.,You can increase your revenue per visitor and overall site conversion which pays for itself.,10,10eCommerce a/b Testing Tool: OptimizelySimplistic UI, but allows you to get dirty in the JavaScript and HTML if necessary. Reporting and validation metrics are easy to explain to non savvy analytic people. Digestible "QA ",Depending on the page scenario, sometimes loads pages very slowly. Don't recommend inserting elements with this tool, the z-index will sometimes be off w/ different browsers.,Validating treatments against controls that build a positive ROI. Allows justification of development time where needed.,8,8,eCommerce conversion. Increase click through rates / increase online conversion. User engagements and how to increase them on landing pages.,,,Implemented in-house,8,Self-taught,Yes, this tool is similar to other A/B testing tools. So if you have experience with them, you'll have no problems.,10Optimizely is the best!It made everything about creating my landing pages and enrollment funnel easier. I was able to change things on the fly and test many options without engineering help. No engineers needed (after javascript snipet is deployed),There were to very complex things I tried to do, that weren't great. One was adding a test popup with js which didn't really work, and the second was using interactive mode to edit a very dynamic screen.,Ability to test messaging and content without investing resources to update.,10,10,A/B testing Content Management,,Implemented in-house,10,Self-taught,Totally easy to use. I taught someone else within an hour.,No,10Easy to use, easy to set-up, easy to get assistanceUsed for website A/B and multivariate testing Great for non-programmers to use Very easy to implement Great customer and tech support,While it does provide API and direct jQuery access, some programmers could possible feel that this solution is a little too "on rails" for them. Not originally designed for Responsive Design websites, however workarounds and user techniques do exist,Great for small but rapid A/B and multi-variate testing Greatly aided user engagement on critical pages by experimenting with variations of key UI elements (buttons, modules, user forms, etc.),9,9Optimizely is for beginners and expertsThe product makes A/B Testing easy. The technical support staff is very quick to respond and very helpful. Most things require no knowledge of html, java or CSS.,There are discrepancies between the Optimizely visitor count and Google Analytics. I have been unable to resolve why these differences occur. The differences are small except with regards to mobile traffic. I am not convinced the mobile tracking works as intended. Differences with Google Analytics are fairly large.,The product has allowed us to quantify $500k in revenue gains and saves (not implementing poor test outcomes). This number is soft, and will certainly decrease as gains become harder to realize.,10,8,3,3,A/B Testing. Conversion Rate Optimization.,,,Implemented in-house,9,Self-taught,The program is very easy to learn, and as more difficult tests are implemented, they have been very helpful in guiding us along the way.,We have in-house (off-site) conversion data that we tie back to tests. This is accomplished through a nightly feed of data to Optimizely and helps us with test results.,10,9,10,10,Google Analytics In-house data clicktale,Data warehouse,Optimizely: a powerful tool for your site optimization effortsUsed for simple A/B tests and to force visitor traffic to pages that have specific messaging or UI elements,Very easy to configure experiment targeting, traffic allocation, and other settings you would want to customize for your testing program Allows easy selection of experiment types like Multivariate, Multipage, A/B Permits simple UI changes using its code editor and other options which allows for decreased reliance on development resources. Product and Design teams can launch new experiments easily on their own Support is first rate: knowledgeable, great communicators who take the time to explain things so that you can learn and apply to future experiments. Optimizely customer support is among the best I've encountered from a web software service,Improvements can be made with experiment results reporting specifically customization of data within the data export or whatever is viewed on the summary page Different organizations could have different thresholds for statistical significance. Optimizely is set to 95%. It would be nice to have this value configurable. It is difficult to ascertain whether a losing variation is a statistically significant loss (only shows low chance to beat baseline). Having this would assist with pausing variations that are not performing very well. Customizable, distributable reports would be a great feature to add. Currently you must click through each individual experiment to see experiment details. Seeing a summary through email or selecting multiple experiments to view on one page would be a huge improvement for scanning health of tests.,7,Optimizely has helped us optimize on micro conversion goals throughout our site Our macro conversion goals have also been optimized using Optimizely,Homegrown A/B platform and Adobe Test & Target,Geckoboard, Asana, Trello, JIRA Software,5,1,Test new ideas/variations against current control version Force visitors to see certain site changes Reports to understand impact of site change,Segment traffic from the various inbound channels,Analytics Performance indicators,8,No,Price Product Features Product Usability,Talk with power users for each product more, and understand what feature they wish they could have but currently don't.,No,7,No,When critical tests were impacting our paid campaigns due to issues with the way Optimizely handled our page, then my request was escalated and team worked to address right away.,Button color and copy Segmenting to different audiences,Working with updating images in a slider carousel Reporting,No,6,6,9,6Optimizely, good for some things, not for all!We use Optimizely to test out some ideas for the UI that people have instead of blindly changing our site, we get great data on the impact of every change we make. Mostly Engineering uses it, but some project managers use it as well.,A/B testing The impact of CSS and HTML edits,Integrating with our database to figure out revenue impact. Optimizely could be more intuitive. You have to dig through documentation in order to set up a simple A/B test.,8,It has allowed us to show whether changing things in the UI give us more clicks.Optimizely does its job pretty wellOptimizely is owned and operated by the marketing department, but has provided value to nearly all departments of the organization. Optimizely helped us test content ideas, solve navigation issues, improve conversion rates, and better understand user behavior.,Optimizely's WYSIWYG interface allows marketers who do not know how to code to make design changes easily. Optimizely informs a marketer when a test is complete and doesn't assume you have a deep understanding of statistics. Optimizely's documentation is thorough and helpful.,Optimizely can allow novices to make many small changes that, in sum, add a lot of overhead to code execution. Optimizely does not have a pleasant way of viewing past tests or exporting results. It can be buggy.,8,Increased conversion rate.,Maxymiser,Google Analytics, TrelloFor a beginner, Optimizely offers great support and an engaging interface to start in the optimization fieldOptimizely is used by our department but affects the whole organization. It helps us evaluate customer behavior on our website so we can make decisions based on analytics. For a time, our company would make decisions on web design based on personal feelings. Optimizely gives us a solid footing on how we make decisions and instigates new creative designs based on those trends.,The interface is easy to use and is always improving. I can select tests easily and navigate to goals and audiences with ease. The analytics are very detailed, especially with their latest update that shows us totals vs uniques. They eagerly engage with their clients, offering suggestions in how and what to test.,Grouping of related goals together to easily add them to similar projects. There are times when I'm running 10 tests with 12 similar goals. It would be nice to add a group of goals and then edit what else I want or don't want. Some of their suggestions do not relate well to the exact context of how your industry works and how customers use your website. The ability to hide/display and move goals within the results. It can be done in a spreadsheet but I would really like to see it in the web interface.,9,Increased sales Increased engagement with marketing content Increased social media interactionBest tool to learn about your client base.We use Optimizely mainly for testing marketing ideas. We use it to make sure the new hypotheses are not affecting our conversions in a negative way.,Ease of use, no need to involve the developers when we want to test on the front-end. Stable platform. So far we never had any noticeable outings or downtime because of it. Powerful tools for advanced users. Writing your own code and skipping the WYSIWYG editor is a breeze.,The company is industry leading, hence the pricing is adjusted accordingly. Makes sense for bigger companies, not so much for small businesses - unless of course they can leverage use on a daily basis with significant results.,10,Tremendous amount of useful data to better understand our clients. Some of our tests yielded huge improvements, affecting our recurring revenue. We couldn't have known that without Optimizely.,Great product, amazing team perfect for A/B testingWe decided to start using Optimizely to increase our A/B testing velocity. We already had an internal tool but it was not flexible enough to be able to run the number of experiments that we wanted to run and have the flexibility to turn on/off experiments out of the release cycle. We have an entire team dedicated to A/B testing with engineers, QA, and a product manager and designer. The team is responsible for the implementation of all our A/B tests; with Optimizely or our internal tool. I am the product owner and I am the person who interacts the most with Optimizely but everybody in my team uses it on a weekly basis.,Product is very easy to implement and to ramp up with. Even non developers can use it. Extremely easy to manage your experiments, to turn them on/off and dashboard very user friendly. Great capability for user targeting, traffic allocation, etc. Reliable analytics tool (they've made a lot of progress in 2015 with their new results page). Amazing team, very nice to work with, always on top of things and very efficient technical support. Using Optimizely has enabled us to double our testing velocity. We also use optimizely for promotion campaign or quick bug fixes.,Sometimes the software can be slow, the dashboard takes some time to load, etc. We still use our internal tool for more complex tests with back-end part. I am still paranoid about the flicker and don't use Optimizely for big tests if it is above the fold.,9,Higher testing velocity Shorter lead time to start a test

  • Digestible "QA "
  • Depending on the page scenario, sometimes loads pages very slowly.
  • Don't recommend inserting elements with this tool, the z-index will sometimes be off w/ different browsers.

Pros and Cons

  • It made everything about creating my landing pages and enrollment funnel easier. I was able to change things on the fly and test many options without engineering help.
  • No engineers needed (after javascript snipet is deployed)
  • There were to very complex things I tried to do, that weren't great. One was adding a test popup with js which didn't really work, and the second was using interactive mode to edit a very dynamic screen.

Pros and Cons

  • Used for website A/B and multivariate testing
  • Great for non-programmers to use
  • Very easy to implement
  • Great customer and tech support
  • While it does provide API and direct jQuery access, some programmers could possible feel that this solution is a little too "on rails" for them.
  • Not originally designed for Responsive Design websites, however workarounds and user techniques do exist

Pros and Cons

  • The product makes A/B Testing easy.
  • The technical support staff is very quick to respond and very helpful.
  • Most things require no knowledge of html, java or CSS.
  • There are discrepancies between the Optimizely visitor count and Google Analytics. I have been unable to resolve why these differences occur. The differences are small except with regards to mobile traffic.
  • I am not convinced the mobile tracking works as intended. Differences with Google Analytics are fairly large.

Pros and Cons

  • Very easy to configure experiment targeting, traffic allocation, and other settings you would want to customize for your testing program
  • Allows easy selection of experiment types like Multivariate, Multipage, A/B
  • Permits simple UI changes using its code editor and other options which allows for decreased reliance on development resources. Product and Design teams can launch new experiments easily on their own
  • Support is first rate: knowledgeable, great communicators who take the time to explain things so that you can learn and apply to future experiments. Optimizely customer support is among the best I've encountered from a web software service
  • Improvements can be made with experiment results reporting specifically customization of data within the data export or whatever is viewed on the summary page
  • Different organizations could have different thresholds for statistical significance. Optimizely is set to 95%. It would be nice to have this value configurable.
  • It is difficult to ascertain whether a losing variation is a statistically significant loss (only shows low chance to beat baseline). Having this would assist with pausing variations that are not performing very well.
  • Customizable, distributable reports would be a great feature to add. Currently you must click through each individual experiment to see experiment details. Seeing a summary through email or selecting multiple experiments to view on one page would be a huge improvement for scanning health of tests.

Pros and Cons

  • Optimizely's WYSIWYG interface allows marketers who do not know how to code to make design changes easily.
  • Optimizely informs a marketer when a test is complete and doesn't assume you have a deep understanding of statistics.
  • Optimizely's documentation is thorough and helpful.
  • Optimizely can allow novices to make many small changes that, in sum, add a lot of overhead to code execution.
  • Optimizely does not have a pleasant way of viewing past tests or exporting results.
  • It can be buggy.

Pros and Cons

  • The interface is easy to use and is always improving. I can select tests easily and navigate to goals and audiences with ease.
  • The analytics are very detailed, especially with their latest update that shows us totals vs uniques.
  • They eagerly engage with their clients, offering suggestions in how and what to test.
  • Grouping of related goals together to easily add them to similar projects. There are times when I'm running 10 tests with 12 similar goals. It would be nice to add a group of goals and then edit what else I want or don't want.
  • Some of their suggestions do not relate well to the exact context of how your industry works and how customers use your website.
  • The ability to hide/display and move goals within the results. It can be done in a spreadsheet but I would really like to see it in the web interface.

Pros and Cons

  • Ease of use, no need to involve the developers when we want to test on the front-end.
  • Stable platform. So far we never had any noticeable outings or downtime because of it.
  • Powerful tools for advanced users. Writing your own code and skipping the WYSIWYG editor is a breeze.
  • The company is industry leading, hence the pricing is adjusted accordingly. Makes sense for bigger companies, not so much for small businesses - unless of course they can leverage use on a daily basis with significant results.

Pros and Cons

  • Product is very easy to implement and to ramp up with. Even non developers can use it.
  • Extremely easy to manage your experiments, to turn them on/off and dashboard very user friendly.
  • Great capability for user targeting, traffic allocation, etc.
  • Reliable analytics tool (they've made a lot of progress in 2015 with their new results page).
  • Amazing team, very nice to work with, always on top of things and very efficient technical support.
  • Using Optimizely has enabled us to double our testing velocity.
  • We also use optimizely for promotion campaign or quick bug fixes.
  • Sometimes the software can be slow, the dashboard takes some time to load, etc.
  • We still use our internal tool for more complex tests with back-end part.
  • I am still paranoid about the flicker and don't use Optimizely for big tests if it is above the fold.
