It’s a well-known fact that site speed is a critical ranking factor for organic search. One of the most-asked questions I receive is: How exactly does Google do this? Over the last year and a bit, I’ve done quite a bit of digging to get the answers. I thought it would be useful to start an FAQ-style repository for the answers.
An historical overview of the evolution of the front-end performance industry, from 1995 to the present, highlighting everyone from early players such as Akamai and F5 to more recent entrants like Strangeloop and Aptimize.
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.
Yesterday the Reddit community made Subway.com the target of a driveby performance critique. Today, Subway.com released a better-optimized site, with thanks to the Redditors.
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.
The folks at Google are the only people I’ve met who have a clearly stated web performance goal: all pages on their sites will load in 100 ms or less. How fast do you want your site to load? And how committed are you to getting there?
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?
Top tech VC Fred Wilson recently stated that speed is the #1 priority for sites and web applications. I put his words to the test by running page tests on 5 sites in his companies portfolio: Etsy, Tumblr, Meetup, Foursquare and Stack Overflow.
