Last December, UK shoppers spent £4.6 billion online and this looks set to rise this Christmas. In fact, according to the IMRG, 93 per cent of UK shoppers intend to buy at least some of their Christmas presents online this year. This means that retailers are likely to see unprecedented levels of internet traffic in the run up to the festive period - excellent news, but how can site administrators ensure they are ready for the Christmas rush?
As shoppers continually look for their online shopping experiences to mirror their offline shopping experiences, sites are using more rich content than ever before. However, such content, which includes video and a heavy use of images, can also slow down the loading speed of web pages, making the user experience painful if sites don’t have the correct infrastructure to cope with it. Therefore, sites need to find ways to ensure visitors do not leave either through impatience, or because a website has collapsed under the pressure of high user volume. So how can sites be exciting and engaging, whilst still offering the ultimate user experience?
Traffic shaping has been talked about as a solution in the past, and now it is a reality. Websites can give preferential treatment through the profiling of online traffic, optimising the user experience for ‘premium’ visitors. For example, if many visitors try to reach a particular web page at the same time, they can be profiled so that those with an item in their basket will get through before someone just browsing, encouraging them to get to the all important checkout.
There are many other ways that e-commerce sites can ready themselves to deal with heavy traffic. Load balancing is a common technique, ensuring that traffic is spread across a number of servers. However, it is now becoming more ‘intelligent’, allowing administrators to inspect and route traffic based on the visitor type. Imagine a busy motorway, where one lane is blocked - with traditional load balancing, drivers automatically manoeuvre their vehicle into other lanes to avoid the delay; whereas with intelligent load balancing, there is a traffic warden guiding cars to the fastest lane according to their size.
When it comes to delivering content, businesses can utilise servers according to location. Content delivery networks can replicate data to servers across geographies so that it is more locally stored for users everywhere, and so takes less time to load. Caching popular content on websites is another way to cut loading time. This means that while something like a video will take a while to load the first time it’s clicked on in a day, the load is then taken off the main web server, leading to performance improvements and an enhanced user experience, as the content no longer loads from scratch.
E-commerce sites are in a Catch 22 position. They are perfectly placed to benefit from the enhanced user experiences available on web sites today, and at the same time too much rich content - particularly at times of heavy traffic such as the lead up to Christmas - could be the reason behind a collapse of their site. Techniques like load balancing, content caching and traffic shaping are great ways to helps sites avoid collapsing, and so increase their conversion rates - however heavy the traffic - and can be the difference between e-retailers having a happy Christmas or not…
