New VWO code snippet: cleaner, faster, easier

Posted in News on

Today we’ve released a change in Visual Website Optimizer code snippet that will make the process of integrating VWO to your website a lot easier! As you will see, the change is a significant improvement over the previous code snippet and we recommend you to update it on your website as soon as possible to enjoy all its benefits (of course, it is backward compatible; So your existing VWO code will also work — but the new one is much faster). The new code is cleaner and much easier to implement The old snippet required you to insert code at two places: one in header and one in footer. The new code requires only one small snippet to be inserted into the website header. Yes, that’s it! No more you are required to add separate code snippets in header and footer. Now, all the code required to run VWO, create…

New feature: email notifications of test results

Posted in News on

We just launched a cool new feature in Visual Website Optimizer: email notifications! VWO already has a feature which monitors your test in the background and disables loser variations or starts displaying winning variation to all site traffic automatically. This ensured that the test reduced risk of losing sales and conversions because losing variations get automatically disabled. Now, we have added email notifications to automatic monitoring so that any time a winner or loser variation is found, you get an email like the following: UWe also did a quick update in conversion goals, so that you can now choose any goal as primary goal (which will be analyzed for crunching email notifications). So, now you can pick the conversion goal (note: you can add multiple conversion goals for each A/B test) you want to monitor, choose to disable losing variations for that goal and simply sit back and relax. You…

The attack of red buttons: how reduced bounce rate by doing a simple change

Posted in A/B Split Testing, Case Studies on

It has been criticized, but it is always guaranteed to work. What is that we are talking about? Yes, you guessed it right: red buttons! No matter how many people consider such A/B tests as a trivial exercise, every now and then they have been demonstrated to increase conversions. The theory of red buttons also worked for one of the Visual Website Optimizer’s users, although they use orange, which fits their color scheme, instead. is one of the Netherlands’ largest eCommerce shops selling mobile phones, GSM plans and other mobile accessories. As you can imagine for an eCommerce site, they have Buy Now buttons used all over the website: product pages, catalogue pages, special offers pages, etc. The challenge for this particular A/B test was that they had to vary ALL buttons on the site at once. A lot of pages (such as the homepage) contain multiple instances of…

New feature: select date range for Visual Website Optimizer reports

Posted in News on

A customer requested this feature, and we obliged! Visual Website Optimizer reports now come with a date picker to let a user see reports only for a specific date range (of course, in addition to the default aggregated report). See below how this date picker looks like: Although test reports should always be analyzed in aggregate (to avoid introducing any statistical bias), this feature will come handy if you want to analyze following scenarios: How do the test variations perform on weekends v/s weekdays (most of the sites get different type of traffic on different days of the week) If you have been running a test for long, and one specific day you saw a rush of visitors due to an ad campaign or press mention, you may want to analyze how test variations performed for this “new” kind of visitors Most importantly, this feature will be useful to verify…

Easiest way to track conversions across multiple domains (using third party cookies)

Posted in A/B Split Testing, How To on
Third party cookies

We’re excited, very excited. Today we launched a new feature that allows Visual Website Optimizer users to track goal A/B test conversions across multiple different domains and sub-domains without doing any extra settings. Due to restrictions posed by the way cookies work, earlier if multiple domains were involved we instructed users to take a hackish approach to track conversions. But now, it just works out-of-the-box. No extra setting, no code fiddling. Finally, cross-domain tracking is a reality. Why is this significant? A lot of internet marketers like to track a visitor across different domains. This isn’t for any malignant purpose, but simply because their services involve multiple domains. Consider following scenarios (all of which our users have come across): Doing a site-wide A/B test where is the main website and is the variation Involvement of third-party payment processor. For example, if your site is located at and…

Consolidated clickmaps and heatmaps: a new method for analyzing visitor activity

Posted in How To, News on

We had launched clickmaps and heatmaps for A/B tests recently in Visual Website Optimizer. Since then it has become the most popular feature amongst our users. We aren’t surprised by the success of this new feature because it gives a new angle to A/B test results. While you can always get information about conversion rate, bounce rate and other hard metrics from standard reports, visualizing “hotspots” on a page has a charm of its own. Based on feedback from a user, we rolled out a new minor feature: consolidated clickmaps. Unlike traditional clickmaps, which show results only for a particular page, this new feature will aggregate click activity on ALL your website pages to show which parts get most clicks. This is useful if you have a website that has common template/theme across different pages (e.g. header, footer, sidebar, product box, etc.). Using consolidated clickmaps, you will be able to…

A/B Testing + Clickmaps = Awesomeness

Posted in Multivariate Testing, News on

Do you know where visitors are clicking on your website homepage? Do you know which parts of your website are hotspots that attract visitor attention? You can, of course, fire up your web analytics tool and tell me that 20% visitors go to sign up page after visiting homepage but that information doesn’t tell you the whole story. First, some stats about Visual Website Optimizer homepage: 30% of visitors who come to homepage visit the sign up page too. Of course, this figure is unsurprising because we have a giant Sign up for FREE 30 day trial button right in the middle. So, a lot of visitors must be clicking on it to arrive on the sign up page? That is what we believed all the while. In Visual Website Optimizer, we had recently released an experimental feature called clickmaps & heatmaps. Clickmaps provide complete click statistics on the web…
