We ignore IE 7 users at our peril. At the time of this writing, IE 7 has 15% market share. This doesn’t sound like much, until you translate that number into 15 out of every 100 living, breathing human beings who come to your site and are rebuffed by its poor usability.
Web page speed tests of the top 20 holiday ecommerce sites – from Amazon to Zappos – showing huge disparities in site speed and page load time. I also demonstrate some new ways to visually present test results to make them meaningful to other stakeholders in your organization.
I ran side-by-side performance tests of TechCrunch, Mashable, GigaOM, Technology Review, and the tech blogs for the New York Times and LA Times. My point: to illustrate why, if you’re looking at just the amount of time it takes for your pages to load, you may be focusing on the wrong thing.
I ran performance tests on 27 leading online retail websites — from eBay to Groupon — to see how fast they load and to illustrate the pros and cons of relying on performance indices and industry benchmarks to evaluate your site.
Kids need an almost instantaneous user experience, with page load times below 200ms. So why does the average kids’ website take more than 9 seconds to load?
As power users, we in the tech community are most guilty of turning a blind eye to slow website performance. So if we can’t trust our own judgment, what can we trust?
Google Instant is going to fundamentally change how people search. Eventually, page 2 search results are going to be irrelevant. Page 1 will be the new bar. The companies that hit that bar will be the companies that are ready to squeeze every last ounce of performance from their sites.
The three greatest third-party performance culprits — performance-leeching widgets, badly designed ads, and poorly optimized pages — and real-world tips for dealing with them.
It’s not enough to have a fast site. Time after time I see “high performance” sites that make the same mistake: having their most important content load dead last. Here’s a case study from Symantec.com.
The mainstream web performance community is rapidly amassing reams of data in this area. But when it comes to the mobile web, we’re pretty much at square one. The problem is threefold: lack of performance-measuring tools, need for large-scale A/B testing, and lack of information sharing.
