Keynote annual review reveals vast diversity in UK website performance

 

By Robert Castley

The sites monitored varied in terms of industry, audience and maturity, stretching from online retailers such as Amazon, through to news sites such as The Economist. The results revealed that there was a worrying disparity in UK site performance, as some sites offered a great online experience – both responding fast and being reliable – while others delivered the complete opposite.

The top performers in the index were Google and HMRC, both of which had an average 2013 availability of 99.95 percent. They also came first and second for response time; Google’s homepage loaded in an average of 0.24 seconds and HMRC in 0.28 seconds. Cable and Wireless wasn’t far off this level of performance and achieved the third fastest average response rate of 0.4 seconds, as well as a 99.92 percent load success rate. The worst performers in the index included The Economist, which had an average load time of 7.45 seconds, as well as Bloomberg and Lastminute.com, which both took more than four seconds to load. For reliability, Halifax offered the lowest chance of a successful load at 94.7 percent, followed by WHSmith at 97.51 percent, and Yahoo at 97.82 percent.

Overall, the sites loaded in an average of 2.07 seconds, close to the recommended response rate maximum of two seconds, with 20 out of the 35 sites achieving this. In terms of reliability, 30 out of the 35 sites had an average load success rate above the recommended minimum of 99 percent, and seven sites loaded correctly 99.9 percent of the time on average.

The performance analysis of different sites during 2013 has shown that there is a huge disparity between good and bad online service from UK sites. A difference of 7.21 seconds between the best average response time and the worst is worrying and will have translated into a very different customer experience. It is great to see that the majority of sites have dipped below the recommended maximum load time of two seconds, however, as overall site speeds to continue to improve, site visitors will become less and less tolerant to those failing to make the grade.

It is interesting to see how travel and news sites tend to fall towards the bottom of the table with regards to speed. Both these industries offer timely information, whether it be for the latest deal or a report on breaking news, and it is critical that they don’t keep site visitors waiting. At the other end of the scale, banking websites tended to load quicker than others in the index. It is fundamental that banks assure customers of a reliable and responsive service and it is good to see that this is being delivered online.

For all sites there may be times when a small content change leads to a performance issue, or there is an unexpected level of traffic. Instead of trying to manage the fallout of frustrated customers, as a result of these problems, companies should test and monitor the site to be able to prevent hitches and rectify any issues that do occur before it impacts users. The most important time for any site is when there is a buzz of excitement – such as a breaking news story or a major online sale – and internet users are heading online in droves. Site owners must utilise this opportunity by presenting them with a fully functioning, responsive homepage or they might miss out on being the first port of call in the future.
