I was just reviewing my Twitter feed for the past week and realized there are a ton of great articles in there that deserve more attention than a mere tweet. I never cease to be grateful for this wealth of great reading around performance and user experience. When I first started working in this space — just half a dozen years ago — performance material was pretty thin on the ground. Today, it’s a struggle to keep up. (Note: This is a problem I’m happy to have.) Thanks so much to all the folks out there who keep this space relevant and interesting!
Important news from the Google Webmaster Blog: interstitials could cost you your “mobile-friendly” label. “After November 1, mobile web pages that show an app install interstitial that hides a significant amount of content on the transition from the search result page will no longer be considered mobile-friendly. The Mobile Usability report in Search Console will show webmasters the number of pages across their site that have this issue.” [link]
Real estate sites are notoriously slow. This is a great case study from Zillow on how they implemented web performance budgets, sped up their pages, and improved the user experience. [link]
Speaking of UX, this is an interesting roundup of stats you may not know (including the controversial claim that you’re more likely to climb Everest than click on a banner ad). [link]
People have strong feelings about content delivery networks. Are they the holy grail of performance, or are they kinda overrated. The answer, of course, is much more nuanced than that. This is a great collection of thoughtful responses — including the good, the bad, and solutions — from thought leaders like Ilya Grigorik, Dan Rayburn, and Patrick Meenan. [link]
If you don’t know what “critical rendering path” means, you should. It’s the foundation for understanding what and how to optimize your pages. This is an excellent primer from Patrick Sexton. [link]
I love this history of the Google logo, along with the performance rationale for its recent redesign, which shrunk it from around 14,000 bytes to just 305 bytes. Aspirational stuff. [link]
Head over to CSS-Tricks and respond to their poll asking how invested people in your organization are in web performance. (The survey is down in the right-hand sidebar.) Answers range from “Nobody cares at all” to “Everybody cares and actively works to maintain and improve”. I’m looking forward to seeing the results. [link]
