All Latest 540 A/B Tests

This experiment tested the order of purchase plans. The control version sorted the purchase options by the least expensive while the variation sorted them by the most expensive first. Impact on sales and revenue was measured.

This experiment variation prompted users to save (bookmark) a company profile on a company detail page. Clicking on the save feature while logged out, would prompt a registration modal. Hence the save feature acted as an extra reason to signup. The number of people engaging or interacting with the feature was measured, as well as registrations.

In this experiment, a lead form on a listing page showed whether an agent was recently online or not. The diplayed had two statuses: either indicating that someone is online now, or the most recent time they were online in minutes.

In this experiment, a dynamic page title was generated and added at the top of the screen. The first few words from a property description were used to dynamically generate these titles. The effect on leads was measured.

In this experiment, we tested a visible "Shipping Frequency" (A) option against a progressively displayed one (B) that would only appear after someone first chose a duration option. Thus in variation B, the buy box component would initially appear with fewer fields and smaller. The experiment measured initial progression and actual sales. 

Note on the data: the experiment was run a little shorter than usual, as one of the variations triggered a stop rule to protect losses (so the effect might be somewhat inflated from a lower power).

In this experiment, larger "Apply" buttons were shown on a casting detail page. The application funnel would take users through a series of steps leading to a paid membership subscription. The experiment measured initial progression and account signups (email signups).

In this experiment, the B variation property prices were framed using higher and crossed out price points from 12 months ago - achieving a relative discount. A tooltip was also shown which explained the higher price point on hover. The example in the screenshot translates to "2% less compared to 12 months ago". This high-power experiment measured the number of leads that were generated on property (product) screens.

In this experiment on a casting call site, pricing information was shown beside the application button. This change shows the effect of setting a price expectation and being more clear that the application process is not free.

In this experiment, realtime social proof information has been added below an add-to-cart button. The variation shows how many users that have viewed, or placed a product into their basket. Translated to "4 visitors have this product in their shopping cart."

In this experiment, a product page showed customer reviews at the bottom of the page (B) instead of hiding them under a tab (A).

In this experiment only the button label changed. The control had a more immediate (next step-oriented) button label of "Upload Your Photos Now". The variation tried a more benefit-oriented button of "Order Now" (hinting at paying and obtaining the product).

AutoScout24 is Europe’s largest online marketplace for new and used cars. As published by Optimizely, they tested a form pre-filled with text that read: ‘Hello. I am interested in your vehicle. Please contact me. Kind regards.’ 

A product landing page with an image was tested against one without - raising the call to action above the fold.

Microsoft Store ran an experiment on the Surface Book 2 product page. The treatment showed a hero image with fewer, yet larger product photos

Microsoft Store ran an experiment on the Office 365 Home product page. The treatment raised the purchase calls to action higher by removing the hero image.

In this experiment, a call to action was repeated at the bottom of the product page. Additional certification icons were also added for additional reassurance.

This test ran on the Suzuki Swift landing page. In the B variation, extra links with the following copy ‘Discover the <name of car model>’ were added for each sub product. (in Dutch: ‘Bekijk de…’).

In the variation, customer reviews were exposed from a less visible tab view.

In this experiment, a number of customer reviews were added at the middle of a product page.
