Part 3 | Five Steps to Improve E-Commerce Performance for Increased Sales

Network Performance

This is the third episode of the mini-series on e-commerce performance management. Our client TescaraHats (name changed for commercial reasons), a European market leader in manufacturing customized hats, did not achieve the expected sales increase with its new e-commerce site. It offered its customers the ability to customize and order hats online instead of visiting its brick and mortar locations, but customers seemed disinterested. TescaraHats learned quickly that there is much more to an e-commerce platform than simply putting an e-commerce service online.

In previous posts we showed that increasing page rank is not the only way to boost sales and that checking and improving back-end performance of your e-commerce is also critical. In this episode we show why you should not keep network load and HTTP errors in check.

Avoid Unnecessary Network Load
Although broadband connection is now a commodity and many Internet users can stream HD videos online from rental services like Netflix, you should still keep the size and the download time of a web site in check. In order to maximize the usability of your site, you should ensure it loads quickly. This is true on mobile devices as well because mobile e-commerce (a.k.a. m-commerce) is said to be taking over the market share.

To begin, check how much time is spent on the network to complete each page. Longer network time, as seen in Figure 1, may indicate that you are pushing unnecessarily heavy content to the client, or the server is busy generating (on the fly) some non-HTML components of the page.

Figure 1: Avoid unnecessary network load: check operation time breakdown and number of hits

Next, make sure your site is properly cached. If a web browser needs to download the same content over and over, even if the page is not too heavy, the footprint of your whole site becomes a burden for returning visitors or those who spend more time on the site.

Figure 2: The speed of the web report tells you if your site is too heavy or the cache is not properly optimized

The report in Figure 1 shows an inflated hits per operation ratio, which may mean that the content is not properly cached. Figure 2 shows a report from the Speed of the Web service, which was used to analyze TescaraHats e-commerce site. The report aligns with findings reported in Figure 1: the caching is not properly configured. Figure 3 shows a similar report from the perspective of images served from TescaraHats site. Both reports indicate that there are too many resources, e.g., images and JavaScript files, served from the same domain.

Figure 3: Analyze the images which need to be downloaded with e-commerce pages to see if you can reduce their number or size, or both

Although the bandwidth of the network connection is usually not a problem these days, the web browsers can only open a limited number of parallel connections. When the page consists of too many items, the site is unable to download them all at once. Figure 4 illustrates the problem with a page sequence load step chart report.

Figure 4: Too many page components cannot be downloaded in parallel, they affect the complete page load time

To solve the network load problem you need to:

  • Make sure all static content is properly cached.
  • Make sure all JavaScript files are combined and compressed into (ideally) one; same goes for CSS files.
  • Try to serve images of higher quality to size ratio; if possible combine smaller images into one and use the CSS sprites technique.
  • Use content delivery networks (CDN) to serve your static content.

Keep Control of HTTP Errors
Sometimes users mistype the URL and end up with a 404 error page. Additionally, sometimes your software may fail and the user will see a HTTP 500 error page. Users have become accustomed to seeing some funny and useful versions of these error pages.

Web developers often forget to ensure that there are no back-end calls that end up with an error. In many cases users will not be aware that those errors even happened, but it does not mean that those errors have no impact on the users. In fact, the calls that end up with an HTTP error not only contribute to the higher network time, but may also indicate application performance problems.

Figure 5 presents a part of report from the Speed of the Web service that shows time lost on handling HTTP 500 errors at TescaraHats.

Figure 5: There are too many HTTP errors reported by your e-commerce site

If your APM tool shows there are HTTP errors: in most cases you need to talk to your developers.

Make Sure You Care About Your Users
When you are certain about your e-commerce back-end performance, decreased unnecessary network load and made sure there are no HTTP errors behind the scenes, it's time to focus on your users who will soon swarm to visit your site. Read the next episode of our series to learn how to make your customers happy.

@ThingsExpo Stories
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
Growth hacking is common for startups to make unheard-of progress in building their business. Career Hacks can help Geek Girls and those who support them (yes, that's you too, Dad!) to excel in this typically male-dominated world. Get ready to learn the facts: Is there a bias against women in the tech / developer communities? Why are women 50% of the workforce, but hold only 24% of the STEM or IT positions? Some beginnings of what to do about it! In her Day 2 Keynote at 17th Cloud Expo, Sandy Carter, IBM General Manager Cloud Ecosystem and Developers, and a Social Business Evangelist, wil...
PubNub has announced the release of BLOCKS, a set of customizable microservices that give developers a simple way to add code and deploy features for realtime apps.PubNub BLOCKS executes business logic directly on the data streaming through PubNub’s network without splitting it off to an intermediary server controlled by the customer.

Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.
Apps and devices shouldn't stop working when there's limited or no network connectivity.

The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
Cloud computing delivers on-demand resources that provide businesses with flexibility and cost-savings. The challenge in moving workloads to the cloud has been the cost and complexity of ensuring the initial and ongoing security and regulatory (PCI, HIPAA, FFIEC) compliance across private and public clouds. Manual security compliance is slow, prone to human error, and represents over 50% of the cost of managing cloud applications. Determining how to automate cloud security compliance is critical to maintaining positive ROI. Raxak Protect is an automated security compliance SaaS platform and ma...

The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.
