How does Visual Website Optimizer work?
When you create your first A/B test, you get a one-time code snippet from Visual Website Optimizer (VWO). Add this code to your website’s HTML and you’re good to go. Create unlimited tests anywhere on your website. There’s no need for you to add the code again.
When visitors land on the page on which you’re running a test, VWO code calls for the test pages set up by you during the design phase. These pages are then randomly served to visitors who become a part of your test(s).
If it is a split URL test, VWO divides the traffic between the two (or more) URLs that you’ve set up for your test. Visitors are randomly directed to these URLs.
Once the page is displayed and the conversion goal is completed by the visitor, Visual Website Optimizer logs it in your conversion data.
Dynamic test data, which has specifically been set by you for the test that is running on the current page URL.
Both the static and dynamic responses are heavily cached by us at our backend. This keeps response times minimal. The (g)zipping and minification of the code reduces these response times even further.
On the basis of the server response, the elements in the DOM (Document Object Model) are automatically replaced to display the variation that the visitor has been assigned.
In case of a Click, Form submission or Engagement as a conversion goal, a VWO function binds to a click event on the page that checks if a conversion has occurred.
After section replacements and binding of goals, the page is displayed to the visitor.
How much improvement in conversions can you expect?
Conversion improvements depend on a lot of factors.
Running small A/B tests, like button color tests or headline tests usually have far lesser impact than running tests with big changes.
Often when your test hypotheses are backed by background research like usability findings, heatmap analysis, or customer feedback, you can expect higher improvements in your website conversion rate.
A/B test results can still be quite unpredictable and best practices may not always work. It is recommended that you test any changes before you make them permanent on your website.
Typically, you should be happy with at least >10% improvements in conversions. In some cases, you can even celebrate a conversion lift of more than 300%.

What types of conversion goals are supported by VWO?
Click on a link - Specify a URL when setting up a test. The moment it is clicked on your test page, it will be counted as a conversion goal. For example, if your conversion goal is the download event, you will need to specify click on the download URL (the value contained in href attribute of a tag) as the conversion goal. And when a visitor completes this action, a conversion goal will be registered by VWO.
Visit to a page - Submit the URL in your test for which the goal needs to be triggered. If a visitor arrives on this URL from your test page, a conversion goal is logged into the data. For example, if you want to track visits to your features page from the homepage, the conversion goal will be triggered in VWO as soon as the visitor is redirected to the features page.
Form submission - This conversion goal triggers if the specified form is submitted by the visitor.
Engagement - It records clicks on any link (i.e. anchor element), button, or input element (with ‘type’ attribute equal to image, submit or button) present on the page.
Revenue Goal - This option enables you to track revenue metrics, like total sales, revenue per visitor and average order value.
Click on Element - This goal tracks a click on any DOM element (or collection of elements) on the page. See this link for more details.
Full factorial approach to multivariate testing
Visitors see same variation even on repeat visits
Conversions can be triggered even on repeat visits
The same test can run on multiple pages on the website
Multiple tests can be run on the same page
The test results are realtime; there is no lag
