Optimizely
Optimizely is a great A/B testing tool for any size business. The Optimizely platform democratizes A/B testing through a simple interface, excellent training tools, easy implementation and low dependence on IT resources. Utilizing Optimizely I've been able to run robust experimentation programs with a variety of resources (acting as a 1-person team with limited access to IT resources as well as managing a team with high access to resources). Additionally, Optimizely is well-priced and positioned to be affordable for a variety of business sizes.

SiteSpect is great for businesses with available development resources and a need to provide flicker-free performance. Additionally, the month-to-month service model is attractive considering the contract and implementation prices of most of the tool's competitors. If an organization wants to run a lot of tests with a small team of marketers, I wouldn't recommend a tool as complex as SiteSpect. Effective use of the tool requires a lot of technical skill.

Pros
Optimizely
- Optimizely makes it extremely easy to setup almost any type of split or multi-variate testing experiment. It has a variety of test triggers types & many ways to segment incoming visitors.
- I believe Optimizely's results dashboard is one of the best among split testing software. It allowed my team to get insights into the running of tests, like time to significance and a view of metric changes over time.
- Optimizely is very easy to use for non-engineers. It has a powerful visual interface that allows marketers and advertisers to setup complex variations without 1 line of code.
- In terms of documentation and implementation, I believe Optimizely is ahead of its competitors in terms of its focus on reliability and speed.

- It is able to intercept the code from your server, inject your code and then it continues on to the end-user's computer with virtually no speed interruptions.
- It has several different options for performing A/B tests from regular factors to client-side factors, and origin experiments.
- It is extremely flexible and configurable for the needs of your company or organization.

Cons
Optimizely
- Actual creation of an A/B test is confusing and difficult (like the differences between Pages vs URLs etc.).
- Setting up a URL Redirect Experiment is so convoluted it seems like it's not even a feature Optimizely wants you to use. Instead, it's like I'm tricking Optimizely into alternating between 2 URLs. That really needs to be cleaned up as it would be very helpful.

- SiteSpect recently came out with a feature to test and optimize mobile applications. I have not used this, but it fills an important capability gap with the product I was using at the time.

Because it's an incredible and essential tool for my line of work as a conversion optimization specialist. Really couldn't do my job nearly as effectively without it. It's paid for itself many times over and I feel like I'm only beginning to unlock the tools potential.

Without a doubt, after 8 years using various different testing tools, Optimizely is by far the easiest to use. Feedback from developers and more technical teams has always been positive, mostly due to the code editor allowing for easy implementation along with the creation of advanced audience segments using advanced javascript. For business users and non-technical people, the wysiwig editor allows for smaller changes to be made quickly whilst somewhat educating the user on the types of code changes that are being made.

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.

Just need to have your requirements ready such as, what you are expecting from the tool, is there anything specific you want regarding reporting, tracking etc.

Alternatives Considered
Optimizely
I think that Optimizely is more user-friendly than Adobe and Monetate, for example - Adobe is really suited for people with deep pockets and a distinct technical acumen that may not be suitable for a small business. Montetate is not user-friendly - even for seasoned marketers. Apptemize is a pretty great product but they killed their free product. Like Optimzely, they seem to be shooting for enterprise-level clients.

I have used all the tools in the market. Sitespect kicks them into the curb based on how easy it is to build variations, and hot it doesnt interfere with client load.

Thus far, Optimizely's overall scalability has been great. Our organization has a white label business that continues to grow and we've had to build up our MarTech stack accordingly, which comes with scalability challenges - especially with the budget. This is something we need to monitor as we continue to grow.
