  3. 3. 1. Why Performance matters?
  4. 4. Every second counts! A fast website leads to more pages viewed, satisfied visitors and ultimately higher conversion rates [1]. Performance is therefore not a feature, but an important requirement for every site owner and online marketer, especially in highly competitive online markets like retail and travel. A mere 250 milliseconds, a blink of an eye, can make a visitor decide to click way [2]. Continuous performance issues can influence your brand’s online image. But there’s a positive side to this story. Fast web pages enable visitors to get into a flow state, in which they start enjoying their visit and will be more focused to buy (additional) goods. Faster equals more page views , equals more potential revenue. “Performance is not a feature, but a requirement” - Fred Wilson, Union Square Ventures [1] Forrester research 4 [2] Google research

Pages aregetting bigger with more 1150content and more thirdparties being used.

  19. 19. Key Findings Performance of Twinkle100 is slower compared to 2011 The average Twinkle100 site keeps on growing. More objects and larger content will result in slower webpages. The difference between #1 (1.70 seconds) and #30 (15,30 seconds) in Travel30 best shows the impact: 268Kb and 38 objects compared to 1191Kb and 108 objects. Retail100 beats the Travel30 in every category An interesting finding is that the Retail100, on average, beats the Travel30 in every category researched. Not only does this result in a slower page load time average, but webpages are bigger in size and contain more objects/third parties. Websites rely more on Third Party Content The usage of third party content keeps growing, from 19% in 2011 to 24% in 2012. Next to the usual suspect like analytics and affiliaties we see a growth in social and testing/optimization tooling. This raises some concern because performance is impacted by the quality of delivery from these third parties. Do you know what their SLA is? 19
  20. 20. Methodology Web Performance is not just something technical, it’s something every online consumer experiences day in day out when surfing the (mobile) web, at home, in the car or at work. Most of the times it’s fun, but sometimes a struggle with content squeezed on a mobile screen, flash adverts, slow websites or failure to load pages. The setup of our performance tests are to measure web performance from a end-users perspective: - Via webpagetest.org which simulates page load times from a real user’s perspective using real browsers, in this case Internet Explorer 8; - Average internet connection with a download speed of 10Mbps and an upload speed of 1.5 Mbps[1]; - All measurements are performed 24 hours per day from December 1st 2011 to August 1 st 2012. - All candidates for the Retail100 and Travel30 are measured during the entire period, so all are compared equal. - For equal comparison only the homepage is measured, since in most cases this is the first page a first time visitors visits. All data analysis is done based on raw data, which means that no averages are used to calculate performance. Based on the revenue per year provided by Twinkle magazine we linked actual performance (speed & downtime) to revenue risked.
