A deep dive into how VWO\u2019s native support to dynamic websites makes experimentation easy for you as you build seamless experiences for your visitors.<\/em><\/p>\n\n\n\n

Many websites are built as Single Page Applications (SPAs) as they have few key advantages over traditional static websites: Dynamic websites are fast, compact and responsive. Such websites enable you to optimize the content that your visitor sees to create engaging and unique experiences. If you hear from your development team that your website is built using React, Vue, AngularJS, Ember, or Backbone, you are probably working with a SPA, and this article is relevant to you.<\/p>\n\n\n\n

In this article, we talk about how we, at VWO, make experimentation<\/a> on dynamic websites effective and easy with in-built support for SPA testing so that you focus only on your website experience optimization efforts and nothing else.  <\/p>\n\n\n\n

But first, let’s talk about the problem that brought you here in the first place.<\/p>\n\n\n

Challenges of running experiments on dynamic websites<\/strong><\/h2>\n\n\n

You are probably here because when you are running experiments on a SPA, the changes you make to your landing page are not visible to the end-users. As a result, you cannot test and validate your ideas as quickly as you want and this leaves you frustrated.<\/p>\n\n\n\n

Firstly, let’s understand that SPAs are different from traditional websites. The entire web page loads each time someone visits a conventional website. In SPA, however, only some sections of the page are updated. This is because, in SPAs, resources like HTML, CSS, Scripts, etc., which build the look and feel of your webpage, are only loaded once. <\/p>\n\n\n\n

Based on how the visitor interacts with different parts of the web page, what you see on a specific section of the page dynamically changes in response to the visitor’s action. Say, if a visitor clicks a button, a pop-up opens. This pop-up is the dynamic change made by the framework as per the visitor interaction without impacting performance. Some more examples where there is dynamic change on a SPA are as below:<\/p>\n\n\n\n
