Benchmark Your Web and Mobile User Experience

Yottaa's CEXi is a compound index that quantifies the desktop and mobile user experience of a web application far more accurately than any single metric. The CEXi combines objective, measurable aspects of performance, such as page load speed from both mobile and desktop simulations, with specific weighting calculations to provide online businesses with an overall performance score that simulates the actual feeling, positive or negative, of using their web applications for a modern, cross-device user.

The Customer Experience Index focuses on three aspects of web performance: speed, parity of experience (across devices), and how well a site is optimized in relation to its complexity.

4D Optimization Technology

Automated App Acceleration and Security with Machine Learning


4D Optimization allows enterprises to accelerate apps automatically, using a machine learning engine to adapt to real-world conditions for a set-and-forget experience without code change. To customize optimizations, our customers can select light customizations, or extract every ounce of performance out of their apps with the most powerful real-time HTML transformation technology in the industry:

  • ContextIntelligence™: Optimize your application for every visitor’s context
  • ContextAgent™: Adapt optimizations in real-time with on-device intelligence
  • InstantON™: Accelerate dynamic apps by 40% with intelligent caching
  • AppSequencing™: Orchestrate 3rd party content without changing code
  • Set and forget: Learn from ongoing interactions across 4 dimensions

  • How the web has evolved, exposing the shorcomings of the traditional delivery paradigm
  • What assumptions are usually made in optimizing applications
  • Prescriptive advice on ways to update delivery mechanisms to meet the needs of current users


Until recently, application development and delivery was owned, managed, and funded by the office of the CIO. That made sense, as it requires specialized skills and development expertise to create an application delivery architecture using Web Servers, Application Delivery Controllers (ADCs), WAN Optimization Controllers (WOCs), and Load Balancers (LBs).

Today the office of the CMO is empowered to accelerate apps using tools and frameworks that have come into being because of advances in HTML and JavaScript, among other technologies. In the modern ecosystem a tech-savvy Marketer or eCommerce professional can harness thousands of tools to optimize end user experiences simply by adding innocuous pieces of JavaScript to their online application.

With great power comes great responsibility, however, and despite their good intentions both technical and non-technical groups within agile organizations are finding that this paradigm can cause as many problems for applications as it solves. Many organizations struggle to align their processes and procedures in a way that ensures a well-optimized application. So with increasingly complex apps and increasingly mobile users, the industry simply requires better tools for content aggregation, acceleration and personalization.

Enter Yottaa’s 4D Optimization technology. Yottaa’s ContextIntelligence™ platform creates a feedback loop that automatically tailors and transforms HTML content to continuously and automatically optimize your content. The process works by evaluating visitor traffic across 4 Dimensions: Geography, Browser, UserAgent and URL. Yottaa’s machine learning engine evaluates every request and infrastructure response across these dimensions to understand, score, categorize and optimize Web applications automatically using patented technology that reviews the context of the request and the payload of the response. The result is increasingly granular acceleration and security optimizations that maximize end user experiences and improve business outcomes.
