Fast, rich, and secure: How to nail web experience in 2019

Modern websites have an ugly secret. On the outside, a website is an elegant display of dynamic content designed to convert visitors into loyal customers. On the backend, many websites are a patchwork of first-party and third-party code, leaving them open to breakdowns in both performance and security. Delivering rich, dynamic web experiences is a heavy burden — and it’s only getting harder. Total page size has been steadily increasing over the last decade, and the trend appears to be continuing. Striking a balance between optimal user experience, web performance, and web security can be tough — but it’s essential for businesses to get it right.

Improved web performance leads to better results

After rebuilding their pages to decrease wait time, Pinterest experienced a 15 percent increase in organic traffic and increased mobile conversions by 40 percent. According to Google research, mobile-optimized websites with fast load times (classified as five seconds or less), had 70 percent longer average session lengths, a 35 percent lower bounce rate, and 25 percent higher ad viewability versus sites that took longer to load.

In addition, research shows that better web performance will increase your bottom line:

  • After shaving 100ms off their load time, Zalando saw a 0.7 percent lift in revenue per session.
  • Trainline reduced latency by 0.3 seconds across their entire funnel, which led customers to spend an extra $11.5 million per year.
  • Walmart experienced a 1 percent increase in revenue for every 100ms improvement.

Now, if this was their experience, imagine what improving the performance of your website could do for your business.

How to optimize web performance in 2019

A modern website should deliver customized content in a fraction of a second, while safeguarding customer information and providing detailed customer analytics on the backend. This is not an ideal to hope for — it is table stakes for businesses that expect to remain competitive in 2019 and beyond. Let’s take a look at some ways you can ensure you don’t miss opportunities because poor performance is affecting the overall web experience of your customers.

Boost the performance of dynamic HTML

Today’s dynamic web experiences often take a performance hit due to the inability to leverage caching, requiring a trip back to the origin in order to render the correct content in a customer’s browser.

Instart CDN intelligently learns which parts of a web page are static and which are uniquely generated at the origin. Non-user specific content, such as static HTML, CSS, and API calls, can be pre-fetched and cached at the edge to allow the browser to start rendering faster, while dynamic content is generated.

The result: significantly lower wait time for the customer who is eager to interact with your website.

Accelerate and streamline first-party Javascript

A recent article published by Google described JavaScript as, “the most expensive resource we serve on the web byte for byte”.  Truncating unused function calls in JavaScript libraries reduce page weight and increases load time.

Instart CDN identifies which first-party JavaScript functions are used most frequently based on customer interaction, fragmenting JavaScript files into smaller, optimized bundles that only sends what is necessary to create the optimal experience for a visitor. Any additional functions that might be triggered are streamed as needed.

Optimize web images

For most websites, images represent the greatest opportunity to reduce payload and increase page load time. On average, images make up over half of the data transferred to render a website. With the explosion of devices, operating systems, browsers, and connections, the task of optimizing images has become an arduous task — it’s nearly impossible for a team to manually ensure that the right image size is rendered for every individual visitor.

Instart CDN automatically classifies images, applies the optimal degree of compression, and then transcodes them into the correct format to ensure that images are served as fast as possible and appropriately formatted for every device and browser.

Upgrade your legacy CDN

Today’s customers have high expectations for experience — they want everything to be personalized, immersive, and blindingly fast. Modern websites and web apps are evolving to meet these expectations, but legacy content delivery networks (CDNs) have remained the same with a heavy focus on scaling with hardware and caching static assets.

Instart provides a global, scalable CDN and a set of performance optimization services that are designed to meet the needs of a modern website, such as accelerating dynamic content and images. With a worldwide caching and delivery network, Instart easily connects customers with website content from all over the world.
