290 Optimizely Testimonials

"It's so important to have a partner like Optimizely out in front for us because with all these things like machine learning, artificial intelligence, search programming, these things are constantly changing."

"Testing is a way of life for us. We're increasing our testing resources, and building testing into our long-term, strategic plans."

“Despite no impact on conversion being achieved for the four-letter test, the three-letter test confirmed the initial hypothesis and resulted in 18.1% lift in orders for visitors arriving via Facebook ads. Facebook represents the largest acquisition source for Lost My Name and clearly demonstrates the value that optimization brings to the business.”

"We're maybe as good as a coinflip at guessing what's going to work best for our users. We rely on testing to just make better decisions. People are really fascinating and interesting and weird! It’s really hard to guess their behaviors accurately."

"With Optimizely, we were not able introduce nearly 1 in 4 U.S. students to computer science, but we were able to launch the fastest growing web-service ever last week, which reached 15 million users in 5 days, faster than Facebook, Twitter, Instagram and Tumblr, combined."

"Ensuring that sales teams have solid leads to follow is fundamental in the B2B marketplace. We wanted a way to deliver better leads without burdening our busy internal IT team."

"Testing helps you make decisions based on objective results, not subjective guesses. It's a good way to be in touch with how the customers react to the content of your website."

"As an online retailer, optimizing our customer's experience on our site is absolutely key to executing our business objectives."

"We're a pretty heavy testing company. We use Optimizely for a lot of the heavy lifting. It's ideal because we can really get velocity and turn results around in a short amount of time."

"Optimizely helped us learn a lot about our users what's working and what's not so we could make changes on our site to optimize our conversion percentages. In the end, this translated to higher revenue for us."

“Of the 14 tests we have run so far on Soulmates, seven have been successful, three have been negative, and four have been inconclusive, in that the differences did not generate big enough changes to reach statistical significance. To know what doesn’t work has been just as informative as to know what does work. A negative test is just a challenge to improve on what has failed and test it again."

"One of the biggest mistakes a company can make is to just assume that the functionality on the big screen will work on the little one. You have to be smart, and pick and chose."

"Optimizely makes building and running A/B and multivariate experiments fast and easy, which enables us to run more tests and optimize our site at a higher pace."

"We try to dial in things like navigation, pricing, shipping options, and promos before the holiday season and then use Optimizely to launch season specific tests, like 'Order in the next X hours for guaranteed delivery by Christmas."

"Optimizely has taken the debate aspect out of design and design by-committee. We let our users tell us what designs are the best layout. If we have a question about what the best design is, we test it."
