I talk to a lot of people who have taken on the role of in-house performance evangelist at their organization, and I know it can be a hard, lonely job. Often it's a self-appointed role because you're genuinely passionate about web performance. And often you're fighting a one-person battle in a workplace that's already struggling to cover a lot of other technical bases with limited resources.
Over the past few months, we've been slowly rolling out Expert Talks, a series of easy-to-digest, solution-agnostic videos that provide brief explainers of key performance concepts. One of our goals in creating this series is to make it easier for you to evangelize within your organization by offering videos that you can use to explain whatever performance issue you're trying to define or solve.
One of the reasons why I love this video is that it does a better job than any other material I've seen (and I've seen a LOT of material) to tell a real-world story of what a page delay feels like in our modern world and how it can throw some unpleasant friction into your day.
Last week, we released our quarterly State of the Union for ecommerce web performance, which found (among other things) that the median top 100 retail site takes 5.4 seconds to render primary content, and 10.7 seconds to fully load.
*NB: Don't panic. Correlation does not equal causation. More on that later in this post.
In our latest quarterly research into the performance of the top 500 ecommerce sites, we found that while 75% of the top 100 websites use a content delivery network, CDN usage doesn't correlate to faster load times. Sites that use a CDN take a full second longer to render primary content than their non-CDN-using counterparts.
Today, I want to discuss why these findings aren't as surprising as they sound, what CDNs fix versus what they can't fix, and how site owners can ensure they're covering all their performance bases.
Performance has only recently started to make headway into the conversion rate optimization (CRO) space. These inroads are long overdue, but still, it's good to see movement. In the spirit of doing my part to hustle thing along, here's a collection of infographics representing real-world examples of the huge impact of page speed on conversions.
Earlier this week, I had the privilege of speaking at the RWD Summit, alongside awesome folks like Tim Kadlec, Brad Frost, and Jenn Lukas. I presented some of the findings of research we conducted here at Radware about how mobile users engage with ecommerce sites, and how this engagement is affected when pages are slowed down even by marginal amounts.
If you’ve been following along with this site over the past four years, you may recall this post, which offered an introduction to waterfall charts. Given that the post is now a few years old, I think it merits a refresh.
Last fall, Twitter founder Ev Williams gave an excellent talk at XOXO* in which he nailed down what makes some online ventures succeed, and others fail:
Yes, your company needs to have rock-solid technology and excellent management, but if what you’re offering doesn’t somehow make your users’ lives easier, then it will fail. So, how do we define convenience? According to Williams:
Like most clickbait, the title of this post isn’t quite accurate. For one thing, this post isn’t about a trick, it’s about a technique that’s been painstakingly developed and tested over the course of the past six years. And it isn’t weird — unless you think really, really smart ideas are weird.
Earlier this month, we released our quarterly State of the Union for ecommerce web performance. Today, I want to share the poster version of the infographics we created to accompany the report. Feel free to download and share. And if you have any questions about any of these findings, let me know.
While TTI has improved since our last quarterly report, there is still a lot of room for improvement. To take a glass-half-full attitude, this represents a great opportunity for site owners who are ready to take the lead in delivering faster Time to Interact (TTI) for their shoppers.
