107% increase in sales shows that customers care more for authenticity than low prices

Posted in A/B Split Testing, Case Studies on June 7th, 2012


eCommerce websites that sell branded products need to ensure that customers know the products are original and not an imitation. If your customers are not sure about the originality, they’re never convinced about the quality of the product and any price will seem like too much. This problem is especially grave in the online world because unlike a physical store they don’t interact with a sales person face to face and moreover they cannot touch [...]

Host Visual Website Optimizer (JavaScript files) on your server

Posted in How To, News on May 17th, 2010

We have released a new feature in Visual Website Optimizer which lets you host the JavaScript files on your own server. This was done because a lot of large corporations avoid including external JavaScript files from a third party. Even though our JavaScript is hosted on Amazon S3 and we have a fail-over strategy that guarantees zero downtime (even in case of our servers going down), some corporations feel much safer if they control the [...]

Bunch of small, new features in Visual Website Optimizer

Posted in News on May 8th, 2010

In the last two days, we have released a bunch of small, unrelated new features in Visual Website Optimizer.

Left v/s Right Sidebar – which layout works best?

Posted in A/B Split Testing, Case Studies on April 23rd, 2010


Answer: none. Using Visual Website Optimizer on my blog, I tested the layout of sidebar to see if it has any effect on bounce rate. Particularly, I tested whether the sidebar in right (default on many blogs) works better than the sidebar on left. The answer for my case turned out to be that it doesn’t really matter. (Though it may differ for you – you should A/B test it, it is really quite simple). [...]
