Overall Satisfaction with Optimizely

Optimizely is, among other things, a conversion rate optimization tool. This allows our creative and development teams to build unique desktop experiences for the many different users who interact with the site. Whether it's testing an A/B (or C/D/E) split among different creative and structural choices or simply just showing a different page for a different geographic location, Optimizely helps target and switch fairly seamlessly.

Sometimes traffic and engagement metrics to websites will stagnate. And Optimizely is a way to test different website layouts to discover winners (or losers) in a statistically significant way.


  • Optimizely does fairly pain-free WYSIWYG web editing. Once the code has been implemented, it is easy to move around pieces of the website, resize and format different elements around the page. You don't need that much experience in coding to operate Optimizely, although it helps.
  • Optimizely allows the team to target and serve different pages based on UTM tags.
  • Optimizely allows unparalleled creativity in determining triggers for different pages to show. With Optimizely, you can discover the geographic location of users, reference this against the weather patterns in their area and serve a different website. This may be a particularly useful tool if your client is REI, for example. REI would benefit from showing a website optimized for cold-weather climates to cold weather climates. The same goes for more temperate and warm climates. Optimizing your website so that users find what they're looking for, convert, and stay longer is the goal. And Optimizely is a great way to start reaching that goal.


  • Perhaps in the certification exams - these seem much easier when described, but take a surprising amount of studying, especially into development specialties. It's mentioned that no developer skills are needed to pass certification, but very specific certification questions are asked regarding JavaScript, HTML, and tagging that the regular account manager or similar jobs wouldn't have knowledge of.
  • It's hard to say without giving up too much of our internal processes.
Optimizely won this bid, so we chose them over Sizemek.
Optimizely is well suited any time you need to serve a different version of a website to varied users or potential customers. It is also well suited when you are uncertain of which version of a website to serve to users. Optimizely provides a no-frills medium within which you may test which version leads to better conversion and optimize towards it.
