Optimizely is a great software solution to address A/B testing and to improve your website!

In a previous job, I used Optimizely a little bit to A/B test our content (especially on our website) and it provided great insight into how people were interacting with our website and was vital to make necessary web and text changes.

Since I didn't know as much about A/B testing when I used Optimizely, I didn't completely know how to best use Optimizely's full range of features and I felt overwhelmed (which wouldn't be the case now).

Optimizely is so easy-to-use that even marketers with minimal coding expertise manage to carry out optimization on their own.

The pricing can be a bit steep for teams who don't have a lot of resources, I wish there would be more customized options available.

Have been using Optimizely for a year and love the WYSIWYG editor (which works great 90% of the time - but can be glitchy on design details).

Easy of use and ability to test before implementing site changes

Support was great during on-boarding process but account management could use some work.

You barely need to know any code to start running experiments with Optimizely. You can literally begin collecting data in minutes.

Optimizely is incredibly powerful and feature-rich, but this creates a steep learning curve. It's quite difficult to use their app even if you're just doing basic experiments.

Drag and Drop builder and A/B Testing suite.

Difficult to integrate with non-optimizely webpages.

Optimizely makes it really easy to test multiple scenarios and find the highest converting solution and then implement. Works for paid testing, organic testing, UX testing. You can test any scenario and see what works best for that specific acquisition channel. It's really useful.

Not incredibly easy to use. Can be time consuming setting up all the different scenarios you need.

- Absolutely amazing dashboard for analysis, really saved our team time vs. individually getting our developers to change one element only to find out it performed worse.. This tool will save you from that

- Incredibly expensive for what our team paid for BUT in terms of a cost/benefit analysis it's paid off (with the time we've saved going to our developers for A/B testing changes to the website, it'll pay itself off in a 1 year or so)

Supereasy to use, implement, track and analyze. Our team uses this frequently and everyone knows how to use it, it's just that easy.

None. Great tool for optimization from A/B testing.

Optimizely is a great tool that marketers can easily use without having much technical experience. The platform makes it easy to do A/B testing, audience segmenting, and analysis to improve performance of marketing campaigns and initiatives.

Great platform is you're able to work it into your budget.

We used Optimizely on some client projects and it seemed to work great. It was easy enough for a non-developer to understand how to use it, but also powerful enough that a front-end developer could inject custom JavaScript and CSS into your webpages in order to manipulate the DOM for testing (for example changing button colors, moving components around on the page, etc)

Not too many things to dislike. There were a few situations were the tests gave us false positives and after implementing the recommendations it actually lowered conversion, but those could have been flukes.

What I can say is that it offers a number of features that other test services do not offer and helped run fast experiments on our websites

is very basic ... when major changes are required, it starts to fail and the price is too high compared to the rest of the market for the product they offer

I really like how interactive the test dashboards are in terms of viewing the data differently for control vs treatment.

I dislike the learning curve required for the product - while it's great to use, it takes a long time to get there. I think it could benefit from some better tutorials or tool tips.

A must have for tech companies.

Always for a much stronger framework for testing and learning.

Expensive and time consuming to implement.

ab testing landing page designs for conversion goals

offers ab testing, multivariate testing, and robust reporting and analytics as well as additional integrations

limited integrations with 3rd parties for visualization and data management platforms are not turnkey

I like the WYSIWYG editor and I like the user interface. It's relatively intuitive and easy to use, and there are a lot of features that you can customize.

We had some serious issues with flickering and lag time. The Optimizely team tried to help us fix this for over 9 months. At the end of the day, we gave up, and given the amount we were paying for this service, it was a huge waste of time and money.

I used Optimizely for two years for A/B testing. It did a good job of randomizing to various conditions and doing basic reporting. The code to implement was also intuitive and low profile on the page.

If you're familiar with the benefits of A/B testing emails, then you'll immediately see the similar benefits with A/B testing websites or mobile apps. We're using Optimizely mainly to A/B test our websites, and as a company that is already at the forefront of the data-driven world with our Big Data offering, Talend is finding success in taking that data-driven approach to our website.

With Optimizely you can create multiple tests and you can expect right directions for landing page improvement. The software is not complex to use, all features are well described.

I have more successful tests than losers, and sometimes I cannot believe that is in 80% my improvement that what I really need. The new pricing model is very hard to understand, they can be improved.

Great experience overall, the support and the resources are great as well.

Optimizely is perhaps the best A/B testing software I've used compared to others. It's definitely the one with the most intuitive dashboard, and the reports are very complete.

Only thing I can think of is you'll need to work with programmers to get things set up, it's not as user-friendly on the configuration side of things.

Split-testing is essential to any online marketing success. Optimizely is one of the best tools on the market, and with good reason. It's easy to setup, use, and implement changes to make sure you're getting the results you want.

The cost is highly prohibitive for many small businesses that are just getting started. That said, those who make the investment will see it provide a good return.

I like how easy it is to test quick visual changes - anyone with basic javascript/html/css knowledge can contribute to a test very easily. The dashboards for viewing experiments is clean and it's easy to monitor tracking around how your tests are doing.

The preview feature is not the most intuitive and many people feel like it's buggy. The fullstack option is extremely expensive.

We have ran optimizely for more than 2 years and getting know the tool was pretty easy since the beggining, We have made some great sucessful test and started changing (more likely, creating) the testing culture. Despite of being so easy, it hold a great power allowing you to make changes to your website without knowing to much about web development. Overall its a great tool

FÁCIL DE USAR

Not reporting incremental revenue per product (just total revenue)

If you've got the money to spend, I haven't found a more comprehensive solution than Optimizely for A/B testing websites. There's a decent amount you can test without being able to code, but fair warning: you're going to need a front-end coder handy for many more-than-basic tests.

Their test results are misleading; they've adopted the most generous tests of statistical significance so that it feels like you're having more successful tests more often. (I.e., results where there are actual differences between the test variances.) Just make sure you do the math yourself on the test results (using any one of many available online statistical significance calculators).

The ability to A/B test anything, and I mean ANYTHING!

Allows us to A/B test versions of our websites and landing pages that we would normally not be able to test. A lot of website builders offer integrated A/B testing, but none of them can offer the insights Optimizely can.

For an A/B split tester, it is a tad on the expensive side, but if you ask me and my team, it is well worth the expense and has paid itself off many times over in optimized conversions.

Set AB testing without needing IT

- Very intuitive; after initial implementation, you can add and change elements without any need of IT anymore. Freedom!!

- the pricing is steep, especially if your website has a large user base (when AB testing becomes more valuable)

It is a great service for A/B testing and conversion improvement. Very easy to install and setup, just add a pice of code and you are done, no extra steps or requirements, we were able to test in about one hour after purchase.

Sometimes if you use for small companies with small budgets it can have an impact on your other work. It's better to use with care

Optimizely is easy to test basic stuff, like simple image changes and type colours and sizes. It gets a bit tricky the bigger your changes become as well as visible content flashing. Experiment CSS/JS is great solution for this but it would be even better if you could limit these to only certain variations. Otherwise a good product.

Optimizely is very easy to implement, and anyone can start experimenting with the product. To get the most value out of the product you will need to invest in managing a test backlog, test plans, and documenting the results of each experiment. It also helps to have someone with strong front-end development and JS skills to implement experiments as it opens up the capabilities of the product dramatically.

Easy to set up, easy to use, good professional support services available

Hard to get to all the functionality without investing development resources

Optimizely is great for A/B testing things on your website. I like how you are able to create different tests for customers to see which layouts work best. There are endless options on how to test things on your site with Optimizely.

AB setup and testing is super easy to do, even if you don't have experience coding you can get a campaign setup in no time.

Overwhelming amount of settings and dials to mess about with make it a little overkill for what we need.

Great AB Testing platform. Easy to integrate

We used the standard version of Optimizely for our website and campaign landing pages. It was very effective for A/B testing and and Conversion rate optimization (CRO). I appreciated that it allowed filtering of audience data and that is supports multivariate testing

The pricing model is too high as compared to other competitor products in the market. We did not renew our subscription after a year owing to this fact

I love that stakeholders and non-technical marketing people can go in and change what I've developer and A/B test without me having to code anything other than include the javscript snippet. I've also been the tester to watch usability by A/B testing and Optimizely is fantastic for that.

It's pricey from the get-go so it was hard to convince stakeholders to invest in it. I think it's well-worth it, but for small businesses it's hard to get started with it.

very nice experience. moderate price. very powerful tool

A/B testing and campaign segmentation are really easy with this software. I'm very happy to use it and will use even more it now that we have a 2nd department

someway difficult to learn the settings to put an A/B test in action but very powerful once you manage how to use it!!

It is possible to edit the page that we want to change with the elements, change texts, images, delete or even modify JavaScript and at the end of everything check how it can be seen in different types of browsers.

Only offers its services for free for 30 days, that is to say that you have to pay certain fees for its use

The best A/B testing tool in my opinion. Light footprint, no screen flickering for variants, experiments easy to set up using the integrated editor and code IDE.

I can't think of anything I didn't like about this software.

We use this tool with the majority of our clients. Possibly the best A/B testing tool out there. Awesome feature set and easy to use!

My work with it mainly relates to setting up campaigns that run on the website and it has been pretty good to use for the time being.

The interface is pretty neat and easy to understand and provides a lot of options for you to customize as per your requirement. Helps you create ads and run campaigns on your websites through easy steps.

At times it does not capture the link correctly and you would need to try doing it a couple of times. A very minor issue this but found it lagging a bit when you try going to a previous page again.

It was fairly straight forward on how to use it to ensure that we were testing adequate sample sizes in order to get significance from our testing.

One thing I wish it had was more information about different testing strategies or ways to optimize current practices.

A product you can rely on. Good documentation and fact customer support

Easy to use, reliable and an overall well though product. I use it daily and it is my to go recommandation for AB testing

The fact that the metrics can't be filtered down by propertries and that you can't create your custom metrics based on existing metrics and properties in the Full Stack version

I've used Optimizely for clients' websites. It generally felt snappy and proved very useful, especially using analytics to prove theories and success.

- Ease of use: Simple to get started experimenting and testing within the app.

- The business model: It started of as a simple SaaS tool and balooned into B2B-ish enterprise land. Where you need to contact sales to even create a trial (if it's even available).

It has been very useful at the time of performing the A / B testing, it adapts to the needs of the client, which is an ideal aspect and the reason why it has been implemented in the company, can be used on different platforms and devices without any Disadvantage providing mobility its use extends from a desktop PC to mobile devices without reducing its software potential.

It is a very simple tool that allows you to perform analytical tests on the web, its interface is complete, it is not necessary to apply a line of code which reduces some time in that aspect, has a good reputation and is also ideal for those beginners who work in web design since it does not require previous knowledge, from my point of view it is an ideal tool that should not be missing in any web development.

Its characteristics as well as functionalities are suitable both for different users and level of knowledge regarding web development, nothing to say about it.

Optimizely is very reliable and powerful. The software has worked flawlessly over the 2 years I've used it. It has enabled me to run many profitable A/B split tests for a large UK brand.

Their tech is flawless. They've put a ton of effort on their stats engine - so you can trust their data. Because the software is so functional and powerful, you'll occasionally need to reference their documentation. Thankfully the documentation is very thorough, concise and helpful.

It's expensive. Not just subjectively. Relatively, within the split testing technology space, Optimizely is one of the most expensive options.!

Optimizely is a great option for experimenting on your website, especially if you aren’t a designer. It lets you easily A/B test what works.

The price point is a little high, especially when you consider that Google offers a free software that is very similar.

It's full of features and can be easily customized. Good WYSIWYG editor with clean interface.

A bit expensive, but really powerful. Can be laggy at times.

I like the way you can build any test you want by modifying the Javascript or CSS of the page, I also liked the user interface, is intuitive enough to do what you need without innitial training.

It's very expensive compared to other tools, if you're on a tight budget I would recommend to start using Google Optimize since it's still free but not as robust as optimizely.

We have ran this software for quite a bit and overall is a great product, easy to use and rich from a feature standpoint.

We found a couple of minor things that were reported at the time and fixed in the following release.

The greatest thing about Optimizely is its setup mode. It is very fast and functions greatly both for websites and mobile devices. Your task is to add their code to your website and you can start optimization. What is more, this software tests everything from button colors to all titles. All changes and errors are depicted on your dashboard. All reports are clear and simple, so you will see everything in front of your eyes.

It should be stated that Optimizely has a few distinctive drawbacks that should be improved. Firstly, a preview mode isn’t perfect. There are cases when it is buggy and it’s rather annoying. Secondly, a function of testing in general lacks of functionality. Often, it is hard to set up and manage tests. Moreover, redirect tests work very badly. The same thing is with Metrics because it isn’t developed enough.

Optimizely makes it easy to setup different A/B testing scenarios, as well as tracking any kind of custom website events you can come up with. With the various tracking options and different tests you can run, it makes it easy to figure out what the best course of action should be.

Overall Optimizely has worked well, but the pricing is a bit high.. I suppose it's a case of you get what you pay for!

Optimizely is one heck of a tool that every marketer should use. Recommended.

As a marketer, I love Optimizely for several reasons.

1. It is expensive. Lowering the price a bit will make it affordable and a lot of startups and small businesses will then be able to use it.

Optimizely makes it very easy to create the most appealing site for customers, because you can test several scenarios and determine the setup that has the highest conversion rate.

The problem with Optimizely is that it make take a long time to create the different variant for the tests.

Optimizely makes it super easy to split test your landing pages. The WYSIWYG editor makes it easy for non-technical users to run effective tests. I also like that you can setup conversion goals easily. For example, you can simply set a goal as clicking a button without any advanced event tracking code.

I've strayed away from optimizely recently just because Google Optimize is free and offers similar features.

I use and teach this tool to Marketing students every week. It's great for setting up A/B testing, which is incredibly useful in our work. It allows you to do this with very little to no coding and delivers clear results.

Not too much to complain about here. I haven't found any competitor that would make me consider changing.

I got the ability to set up A/B tests on my website. Nothing too special, since there's a bunch of other software out there that will do the same thing.

I was attracted to Optimizely because it's a low-cost tool to run A/B tests on websites. Even though their prices have changed over the years, it's still one of the lowest-cost solutions out there. It's also easy to use, because the most time-consuming step is putting the code on your site. If you have a small website, you can get it done in a few minutes.

Preview mode is really buggy. I also wish there was a way to segment the results by audience. For example, if I'm running a different type of traffic to a page I want to be able to see a separate page of data specifically for that. The new goal setting flow is also buggy, but it is new. Hopefully they fix all the kinks as time goes on.

Getting know the tool was pretty easy since the beggining, Despite of being so easy, it hold a great power allowing you to make changes. With this tool, can check which web page is working best, thanks to the A / B tests. This option allows you to compare two pages with their different elements. In real time.

Is a robust and reliable application, easy to configure, easy to use, with good professional support services. I like the fact that you do not need to know how to code and allows us to concentrate on running multiple tests. Very intuitive and easy to use. For more advanced users, you can also access the raw code, which you can specify to those things that the editor may have done. I enjoy the Optimizely analyzes.

The URL does not have a bulk upload option for unrelated URL lists. It has matches of substrings and regular expressions that cover most other needs. The price is higher than some tools. It is difficult to reach all the functionalities without development resources.desarrollo.

The most advanced A/B testing tool so far, it has a huge knowledge base, it's solid,trustworthy. it's surprisingly easy to set up and the results are brilliant.

Optimizely can be a bit expensive for a smaller companies and/or if not used at it's full potential, however it's not an issue for a more experience users from large businesses.

It delivers what it is supposed to without any hidden gems.

The pricing should be more transparent to new users (seems to be focused more towards big companies). Also sometimes the preview mode can be buggy

Lot's of stats for my A/B testing were generated quickly

The software allowed me to quickly setup my A/B testing on our Home Page. I was able to start getting stats in just one day.

Some of the interface at the time was hard to understand. I had to read through a lot of online help to fully understand the product.

This is a great program to AB test web pages. There are some functionalities that let you tweak designs without coding. The analysis is displayed nicely and in a great format to present to other stakeholders.

To get really different pages with certain functionalities you will need development to help create this.

I've witnessed clever usage of Optimizely increase the revenue through cart checkout conversion by 15% by simply testing the removal of elements on the check-out page that are not essential. The set-up for the experiment was straightforward and required only some technical assistance at hand.

I'd have liked to continue using Optimizely for my own small venture, however the pricing makes it unaffordable for a small business. But that's definitely one to keep on the radar as it has powerful and comprehensive solutions for A/B Testing.

With this tool, you can check which web page or landing page is working best, thanks to the A / B tests.

This software is very expensive, but it is really worth its initial price, everything else is wonderful

If ou are looking for a simple set up website testing solution allowing AB Testing, split test or multiviraiant testing - AB Testing is a good option. Still not very expensive solution and wih easy set up you can learn your audience preferences.

Preview function can be buggy, especially for complex long web pages. Optimizely is expanding business so their pricing model might be changing

It is possible quickly set up various tests without requiring any developer assistance. Also it can add and change elements without any need of IT anymore. It is to easy to setup an A/B test on the website or inside the app.

This software is very expensive. Also their test results are misleading. It requires coding skills for more advanced A/B testing.

Makes A/B testing a breeze. You can quickly set up various tests (like changing button text) without requiring any developer assistance.

Would love to see deeper integrations with 3rd parties. You can skew some of your Google Analytics data based on the fact you ran tests.

It did the job. We were looking for an A/B testing solutions that had support for campaigns and Optimizely did the job and fit the bill.

The cost is on the expensive side but if you have the budget you get what you pay for. Otherwise there are cheaper alternatives that may fit your needs.

I have used several ab testing software and this one is the easiest in use. Furthermore their support is very good. When I experienced an issue a solution was found very fast

Compared to other software I used this one is the most expensive and furthermore there also needs to be an investment in development resources

Web experimentation has never been easier. With this product, I can easily test 2 (or more) versions of the same website and get reliable results quickly.

The software is a bit feature-heavy. I don't always use all of the options available. But, that's less of a con and more of a personal need issue.

I really like the fact that you don't need to know how to code, you can just install it on your site and boom! You can use it

I don't really like the price point, but then again you get what you pay for, so it could be a frugality issue!

I like that there is WYSIWYG editing of content that allows non-technical folks to A/B test. I also like that they expose custom Javascript fields so technical folks can make further optimizations if needed.

Wish there was a non-grandfathered free tier, and also think that they should automatically log information based on which div classes and ids are clicked on a page without having the end user manually define which elements are of interest to them.

I took a CRO course this past year and Optimizely was the go-to A/B testing software. Here's why: #1: Super easy to use. You do not need to know how to code, anyone can set up a test and launch it same-day.

I've used Optimizely in their free account, and I can't believe how powerful the software is. I was able to replace content on my site for half of the visitors, finding out that an old call to action was actually more effective than a new one we'd replaced it with - by 33% over a 10,000 visitors test. Having this information makes my efforts so much more useful and strategic. No one in marketing should be blindly creating content.

We're using Optimizely to confirm our improvement hypothesises and our front end/design team wants to make changes to the UI. Using A/B tests with Optimizely, we measure different kinds of user engagement (search actions, registrations) and use the results to help drive design decisions. On-boarding and support from Optimizely was first-rate. I'd recommend for anybody looking to start use A/B testing for their front end.

- Test setup is fast and easy, without using lots of time and effort.

- The previews often never load - this could just be our network.

I have been using Optimizely for over 2 years now. In my previous role I used another testing and targeting tool that was much more complex to use. Optimizely's user interface is intuitive and the statistical algorithms give you confidence in selecting a winner. The best part about Optimizely is it's support. They have a support line and they will work tirelessly until your issue is resolved. I recommend Optimizely's platform to anyone looking to increase web conversions or provide more personal web experiences.

- Fácil de usar

The price is higher than some tools but you get what you pay for.

Optimizely is definitely the most advanced and widely referred to as "industry standard" conversion optimization tool currently on the market. It's easy to use for beginners and incredibly flexible for the most advanced users/tests. Top notch support and community, always eager to help out and inspire new optimization ideas.

Robust, trustworthy, flexible, huge user base, huge knowledge base

Expensive, but only if you're not using it to its full potential.
