Depending on where in the world you are, right now you might be enjoying the final weeks of summer or the winter wind-down. If you're on holiday, there's a good chance that your web performance work is the last thing on your mind. Though if you're out and about – using travel apps and staying up to date on the news via your phone – there's a very good chance that you're experiencing firsthand the real-world effects of other people's performance work (or lack thereof)... both good and bad.
If you want to dig into those effects, our Industry Benchmarks let you poke into the performance of some of the most-used travel, ecommerce, and media sites in the world. You can drill down into each site and find out what makes The Guardian and Le Monde deliver meaningful content so quickly. Or how Trivago and HomeAway help travellers on the go, even under slow mobile conditions.
Also in this newsletter, we share a roundup of powerful image optimization tools, real-world performance culture tips, Core Web Vitals news, and a great ecommerce case study from our friends at Farfetch.
Wherever you are, I hope you're enjoying whatever season you're in. Until next month, stay safe, happy, and well.
How Trivago delivers a fast mobile UX
Your CDN may be great, but it's not enough
If you rely on your content delivery network (CDN) to do all the work of mitigating your site's performance and UX issues, that's not enough... especially for mobile. Every site in this recent snapshot of our US benchmarks for media sites uses a CDN. Yet the Largest Contentful Paint time – which measure when the page's key image is visible – for each site ranges from 8 to 83 seconds for mobile.
Wondering what you could be doing to fix issues on your pages? These are some of the most common solutions we recommend:
You can look at your own SpeedCurve data to find out which optimizations we recommend for your pages. We run Lighthouse tests on all your synthetic tests, and you'll find your audits (aka recommendations) on your Improve and Vitals dashboards, as well as when you drill down into your individual synthetic test results.
Powerful image optimization tools
Optimizing the size of images can have a bigger impact on performance than all other areas combined. In a recent Smashing magazine article, Louis Lazaris covers different tools – both free and paid – available for reducing the size of images.
Farfetch sees higher conversion rates for better Core Web Vitals
This is a great case study from our friends at luxury retailer Farfetch. They correlated Core Web Vitals and performance metrics with business metrics, and found that conversion rate increased by 1.3% with each 100ms reduction in Largest Contentful Paint (LCP).
If you use SpeedCurve RUM, good news! You can create your own correlation charts that show the impact of performance on business and user engagement metrics. Correlation charts are a fantastic tool for driving interest in performance from non-technical stakeholders in your company.
Real-world performance culture tips
If you read the Farfetch case study above, you learned that they built a performance business case calculator to drive product decisions and build their performance culture. That's because having a strong culture of performance in your organization is possibly the single greatest predictor of success.
