Delivering a great user experience throughout the holiday season is a marathon, not a sprint. Here are ten things you can do to make sure your site is fast and available every day, not just Black Friday.
Your design and development teams are working hard to attract users and turn browsers into buyers, with strategies like:
However, all those strategies can take a toll on the speed and user experience of your pages – and each introduces the risk of introducing single points of failure (SPoFs).
Below we've curated ten steps for making your users happy throughout the holidays (and beyond). If you're scrambling to optimize your site before Black Friday, you still have time to implement some or all of these best practices. And if you're already close to being ready for your holiday code freeze, you can use this as a checklist to validate that you've ticked all the boxes on your performance to-do list.
Our development team recently emerged from an offsite with two wonderful improvements to SpeedCurve. The team tackled a project to unify our filtering, and then they over-delivered with a re-Vital-ized dashboard that I'm finding to be one of the most useful views in the product.
Take a look at the recent updates – and a big thank you to our amazing team for putting so much love into SpeedCurve!
Sia Karamalegos is a web performance diva we've come to know through her many articles, workshops, conference talks, and her stint as an MC at performance.now() last year – not to mention her role in speeding up a pretty big slice of the internet!
Sia is kind, funny, smart as heck, and always down to talk web performance (especially if you have a Shopify site). For those reasons and many more, we are excited to share that Sia is this month's Performance Hero!
Here's a detailed walkthrough showing how to make more meaningful and intuitive attributions for your RUM metrics – which makes it much easier for you to zero in on your performance issues.
Real user monitoring (RUM) has always been incredibly important for any organization focused on performance. RUM – also known as field testing – captures performance metrics as real users browse your website and helps you understand how actual users experience your site. But it’s only in the last few years that RUM data has started to become more actionable, allowing you to diagnose what is making your pages slower or less usable for your visitors.
Making newer RUM metrics – such as Core Web Vitals – more actionable has been a significant priority for standards bodies. A big part of this shift has been better attribution, so we can tell what's actually going on when RUM metrics change.
Core Web Vitals metrics – like Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS) – all have some level of attribution associated with them, which helps you identify what exactly is triggering the metric. The LoAF API is all about attribution, helping you zero in on which scripts are causing issues.
Having this attribution available, particularly when paired with meaningful subparts, can help us to quickly identify which specific components we should prioritize in our optimization work.
We can help make this attribution even more valuable by ensuring that key components in our page have meaningful, semantic attributes attached to them.
Paper cut: (literal) A wound caused by a piece of paper or any thin, sharp material that can slice through skin. (figurative) A trivial-seeming problem that causes a surprising amount of pain.
We all love big showy features, and this year we've released our share of those. But sometimes it's the small stuff that can make a big difference. We recently took a look at our backlog of smaller requests from our customers – which we labelled "paper cuts" – and decided to dedicate time to tackle them.
Are they all glamorous changes? Maybe not, though some are pretty exciting.
Are they worthy of a press release? Ha! We don't even know how to issue a press release.
Will they make your day better and put a smile on your face? We sure hope so.
In total, our wonderful development team tackled more than 30 paper cuts! These include:
Keep scrolling for an overview of some of the highlights.
We've made improvements to how we collect RUM data. Most SpeedCurve users won't see significant changes to Core Web Vitals or other metrics, but for a small number of users some metrics may increase.

A recent analysis of twenty leading websites found a surprising number of page speed optimizations that sites are not taking advantage of – to the detriment of their performance metrics, and more importantly, to the detriment of their users and ultimately their business.
I spend a lot of time looking at waterfall charts and web performance audits. I recently investigated the test results for twenty top sites and discovered that many of them are not taking advantage of optimizations – including some fairly easy low-hanging fruit – that could make their pages faster, their users happier, and their businesses more successful.
More on this below, but first, a few important reminders about the impact of page speed on businesses...
Michelle Vu is one of the most knowledgeable, helpful, kind people you could ever hope to meet. As a founding member of Pinterest's performance team, she has created an incredibly strong culture of performance throughout Pinterest. She's also pioneered important custom metrics and practices, like Pinner Wait Time and performance budgets. We are super excited to share that Michelle is this month's Performance Hero!
Our customers often tell us how much they appreciate the user-friendliness of the articles we create for them, so we recently decided to make them available to everyone (not just SpeedCurve users). Introducing the Web Performance Guide!
The Web Performance Guide is – as its name suggests – a collection of articles we've been writing over the years to answer the most common questions we field about performance topics like site speed, why it matters, how it's measured, website monitoring tools, metrics, analytics, and optimization techniques.
You'll find the articles grouped into these topics...
