Trivago, Wix, JD Williams, Missguided and more.
There's a lot of competition to define the next big unicorn performance metric, but does this unicorn actually exist? In the past, we relied on metrics like page load time, start render, and time to first paint to measure user experience, but we now know that these metrics don't tell the full story.
The key to a good user experience is quickly delivering the content your visitors care about the most. This is easy to say, but tricky to do. Every site has unique content and unique user engagement goals, which is why measuring how quickly critical content renders is a hugely challenging task.
Tammy will walk through a brief history of UX and web performance research, highlighting landmark studies that helped connect the dots between performance and user experience. She'll also demystify the current state of performance metrics and help you understand what you need to focus on for your site and your users.
There's a common misconception that making a Progressive Web App means creating a Single Page App with an app-shell architecture. But the truth is that literally any website can benefit from the performance boost that results from the combination of HTTPS + Service Worker + Web App Manifest.
Like it or not, a huge part of modern web development involves the use of third-party providers: fonts, analytics, ads, tracking, and more all have an impact of performance, and can leave us (or, more worryingly, our visitors) susceptible to performance degradation.
In this talk, we’ll take a look at unruly or uninvited (third-)party guests: how to detect them, how to audit them, and how to manage them. We’ll also look at the different tools available to help us stress-test and quantify the overhead these third parties bring, and what that means for users and businesses alike.
There are some exciting new developments happening in the web platform right now. New APIs such as CSS Grid, Web Components, Custom CSS Properties and the Web Animation API. Each on their own is a complex topic worth getting to grips with but what this talk aims to show is how they can be used with each other when used together the result is greater than the sum of its parts. There is only a brief introduction to each topic so some prior knowledge for Web Animations, Custom Properties, CSS Grid and Web Components would help but is not required.
Somewhere on a university campus in the US midwest, a 20 some year old student was earning minimum-wage, writing code in the middle of the night that would forever change the world. Until 1992, the internet was largely textual, reserved almost exclusively to academia, with the charm of searching for library books via antiquated card catalogs. The sea change was a browser called: Mosaic. Marc Andreessen, the young minimum-wage earner, co-authored Mosaic and in 1993 it became the 1st consumer-friendly browser, described once as the “gateway to the riches of the internet”. 25 years later, these same internet riches have become richer content, browsing has become as quotidian as a cup of coffee though not without a touch of tumult. “The Shape Of The Web” is about both accomplishments and challenges that lay in past, present and future of the web, its technologies employed and its employed technologists.
As Timbo said, the web is supposed to be for everyone. So why isn't it, and how can we get the web to more people? Seren Davies and Bruce Lawson, the web's very own Harry and Meghan, will reveal more.
Missguided are one of the UK's most innovative and fast-moving fashion retailers but as with many other retailers, web performance hasn't always been our highest priority.
In summer 2017 we started to make performance improvements and as a result, Android revenue increased significantly. Spurred on by this success we created a dedicated performance team and embarked on a journey to dramatically improve performance right across the site. All sites evolve over time and ours was no different, there was legacy code to be unpicked, new techniques to try and stakeholder needs to balance.
In this talk, we'll share some of the approaches we took, the challenges we faced and the lessons we learned. We'll also talk about the performance and revenue gains, and as ultimately getting faster is about making customers happier, their reaction too.
Inside and out of the technology sector, more people are talking about diversity than ever before. That means it matters to us as a society. That’s good, because I care deeply about diversity, and I need you and all of us to care.
Wix is the leading DIY platform for building an online presence, hosting over 100 million websites. Providing high-performance service is of topmost importance to us, and is one of our main goals for the entire company. In this case-study I will review how we implemented a process of continuous performance improvement, the methodologies and technologies we used, the results we were able to achieve, and our plans for the future.
It’s pretty widely accepted that performance impacts business success. So where do you start and how do you make sure you’re successful? It’s not just about making the slowest pages faster or having the fastest root cause analysis in a fire drill. We need to start to manage performance like a product and use data to gain clear prioritization of efforts and improve performance where it matters most.
There will always be emergencies, but we can use product management strategies and data to help us work smarter; allowing us to identify and focus on the most impactful places to optimize. Maximize efforts and impact by making sure you and your team are focused on what matters most to your company, customers and bottom line. We’ll step through some of the keys of product management and how to apply them to performance and optimization projects.
At FT we built one of the world's fastest media websites, and release to production dozens of times a day. But the architectural and organisational decisions aimed at allowing us to deliver reliable features quickly and consistently don't always fit neatly with the desire to optimise performance.
In this warts-and-all talk, you'll learn
Let's break down what makes up a PWA (progressive web app). Then build one ourselves; looking at what tools we can use to help save time making them and what performance benefits they can bring us.
In July 2017, Pinterest formed its first-ever dedicated web performance team. In this talk I will discuss how the performance team got off the ground, set goals, built tools, and made performance a priority at Pinterest.
Topics will include building a regression testing and investigation framework, finding the biggest optimization wins in our codebase, making customized metrics decisions by relating performance to engagement, and understanding what performance tooling developers need.
How do 3G and 4G connection speeds differ across countries? What is the effect of 301 redirect on user experience, and thus on conversion rate? These are some of the questions connecting web performance to UX and business metrics that we will be looking at in this talk.
HTTP archive, although very useful, consists of data points that constitute what is known as synthetic measurement, since these numbers are obtained from pages loaded from a browser in a datacenter and not from actual users. That changes with the Chrome User Experience Report that Google launched last October. This Real User Monitoring (RUM) data for Google Chrome users include key user experience metrics for 10,000 websites from real users.
We will analyse this data to answer these questions, our experience in digging through this dataset and potential pitfalls to avoid when analysing it.
Web Performance has always been a term used in business that has many meanings. After finally being able to show a direct correlation between webpage load time and impact on e-commerce conversion Nbrown has brought web performance to the centre of the N brown road map. This talk will take you through our journey from an IT metric to a company-wide focus.
Every day the trivago hotel search website enables millions of users to find their ideal hotel in over 190 countries. With over 50 active locales and annual traffic growth of over 40%, maintaining optimal web performance is key to trivago's success as a business.
In emerging markets, maintaining optimal web performance can become a challenge: varying network conditions and different device topology cause issues. Thanks to trivago's rigorous testing culture, we identified these issues in one of our key emerging markets. We ran comparative tests to improve performance, tied the resulting data to trivago's business metrics and correlated it to conversions, more page interactions and a significant increase in new users.
In this talk, you'll learn how trivago measures performance, how we run complex multivariate tests to calculate the business value of engineering and how we optimised performance for one of our key emerging markets.
In a world of unreliable networks and vastly differing device capabilities how can we ensure that we always deliver a fully functional user experience? Let’s go beyond the theory and look at some practical techniques used at BuzzFeed to create resilient front-end systems.
What’s common for Meryl Streep, Henry Ford and Albert Einstein? All of them suffered from different problems in their professional lives despite their success. This talk *is not about development*. Instead of code, this inspirational and motivational talk will set debugger on ourselves as humans to analyse the bugs most of us face in our day-to-day jobs as developers. Among others, we will be talking about:
But these are not limited to developers and are applicable to a much wider audience. It will be about psychology, neuroscience, work-life balance, work quality and… us.
This talk will discuss the new QUIC protocol and why it is needed/important for web performance in particular. I will start by discussing the shortcomings of the current HTTP/2 setup and how QUIC aims to help solve them. I will discuss the bolder aspects of the new standard and the open challenges.
The second part will detail our own experience in developing a QUIC implementation and from looking at other open source implementations. This will also incorporate some findings from related state of the art academic research on QUIC. We end by contemplating how quickly the new standard will evolve and what developers can do in preparation, especially if they have not yet transferred to HTTP/2 yet.
