[MUSIC PLAYING] AANCHAL BAHADUR: Good afternoon. Thank you all for being here. You're almost through
day one of I/O, so we're really, really
glad that you're here. I'm Aanchal. I work on the product
partnerships team here at Google and
I support Chrome. Our goal is to help
developers like all of you build great websites so
you can be successful and make those experiences
for everyone everywhere. While framing the
context of this talk, I was naturally inclined
towards anchoring it on the core benefits
of the web-- its massive reach, frictionless
access, and the fact that a website just works no
matter where you are. You could be on the
fastest internet connection or you could be busy
playing the offline dino game-- it just works. And yes, this is what
has kept the foundation of the web solid and
steady for over 30 years. But there's so much
path-breaking development that's happened in
the past few years. With service workers and
Progressive Web Apps, or PWAs, things are changing. Just by making small changes,
developers across the world are seeing that they're
delighting their users, they're finding new ones,
and they're ultimately seeing great results. Here are some examples of this. Tokopedia, the biggest
marketplace platform in Indonesia, is seeing that
by using a combination of AMP and PWA, they're seeing five
times higher conversions on their website. And if like me, you
enjoy listening to music, you can do that on Spotify on a
Chromebook on their Progressive Web App on desktop, and they're
seeing higher engagements from these installed PWAs. In Brazil, Terra or
"Te-ha," a news publisher, has seen that users are sharing
more articles after they implemented the Web Share API. And Bücher, or Büch-- Bücher, I might
have messed that up. I apologize to anyone
who speaks German. But a leading German
books and media retailer has a top performing PWA, and
they use Trusted Web Activities as a building block for
their Play Store experience. These core values of universal
reach and reliability, when you combine them
with the new superpowers, they can help you solve
real world problems for all your users. Let's walk you through my
daily routine as an example. So the first thing
I do when I wake up, even before the
caffeine kicks in, I check my email,
messages, what's going on in the world, what's
happening back home in India. And sometime during the day,
I hit my lowest productivity hour, and after a heavy
lunch, I go onto social media and I ask some very
profound questions. That's still bothering
me, by the way. And then, once I go home,
I obviously sit on my couch and am binge watching the
latest episodes of some show. That's a crazy routine. It goes against
everything they tell you about digital
well-being, so please remember to hit Pause
every once in a while. Here's a quote from someone
who lives and breathes the internet. The point is I'm
in this business, but when I wear my
user hat on as a user, all I want is a fast,
seamless experience. I don't care how I would
have consumed that news, those tweets, or those shows-- I just want it to be seamless. As developers, all of
you have a choice-- which of the
superpowers will you use that will
delight your users? You have different locations
that your users are present in, different markets,
mature, emerging markets, different connection
types, low-end devices, the fastest smartphones-- you're building for
everyone, and so it's important to keep that
in mind as you look to be successful in the long term. There are developers
amongst you who have made some great choices
to delight their users. Let's talk about
Twitter's web experience. I remember when Twitter shipped
their PWA two years ago. It was a turning point in
the broader adoption of PWAs. I had heard many reviews
about the Twitter experience, the new PWA being light,
fast, and everybody was just really happy using it
and not all these people worked at Google. These folks used the new
capabilities of the web across mobile and
desktop, and they're able to do this all in one
codebase, which has resulted in business outcomes. Sometimes a focus on performance
can make all the difference. The Times Group, the largest
media conglomerate in India, has seen that by just
having a laser sharp focus on performance, a lighthouse
score that is always at 100, they're seeing business
outcomes and they're doing this in a remarkable way. And then finally, Hulu, an
online streaming service, identified an opportunity
that was almost entirely based on user feedback. Their users were saying
things about a great website, but they were complaining
about it not being installable. And so they brought the
two worlds together, built a desktop PWA,
and now they're-- and it's not been too
long, but they're already seeing great business results. Wouldn't it be cool if
these companies were here to tell you their stories
in their own words? So as you applaud me
for my genius setup, please welcome Jesar and Charlie
to tell you about Twitter. [APPLAUSE] JESAR SHAH: Hi everyone. My name is Jesar and
I'm a product manager on the web team at Twitter. CHARLIE CROOM: And
my name's Charlie. I'm one of the engineers who
helped build Twitter's new PWA. JESAR SHAH: And we are very
excited to be here today to talk about Twitter's journey
of building one universal web app to serve people in both
emerging and mature markets. So Twitter is the platform
to find out what's happening. Our mission is to serve
the public conversation. That starts with giving
everyone the access to create and share ideas
and information instantly. One of the ways
we aim to do this is by building experiences
that are available to people no matter what device they use. So we were here in
2017 to talk about one of those experiences--
our mobile website that we had just
launched as a PWA. But a lot has
changed since then. Twitter's PWA has grown since
2017, and is also more powerful now. We're available on almost
every browser and almost every operating system. This wide reach spans
a huge diversity of use cases,
customers, and devices, so this, for us, prompted
a fundamental shift in how we build our web experiences. We viewed our Twitter
users as our customers and we wanted to ensure we were
building a universal app that was responsive to
their diverse needs. One of the major benefits
of building a universal app is that it allows us to build
once and ship to everyone in one single codebase. Our users benefit from regular
updates and consistency across platforms, which
makes a better Twitter experience overall. And, organizationally,
this allows us to move faster as a team and
have more focus on the things that matter most to our users. So in order to
achieve our vision of building a universal
app, we needed to extend the functionality
of our PWA to all devices. There are a lot of devices
out there, some of which are on the screen, and the team
brainstormed dozens of things that we needed to improve. We built our roadmap by
launching smaller units of work and getting public feedback
at each step of the way to help us iterate and improve
on the user experience. We started with the mobile
logged in experience and have worked our way through,
replacing some of our legacy desktop apps with the PWA. At each milestone,
we considered what was unique about the set of
customers that we were adding. How did they access
Twitter differently, and how can we meet their
needs through the web product? In particular, when
we did research across devices and
markets, we found a difference between mobile
and desktop use cases. Mobile web is expected
to be fast, lightweight, and cost effective. People tend to use mobile
web when they're on the go or looking for quick
information on Twitter. Desktop web, on
the other hand, is expected to be more
powerful, task driven, and additive to the
mobile experience. People tend to use desktop
web in a stationary setting with more time and intent to
consume and create conversation on Twitter. So, given the differences
that we saw between mobile web and desktop web, we needed to
pick one as a starting point. We know that the majority
of our users on Twitter use mobile devices to access the
public conversation every day, so with that in mind, we decided
to start with mobile first. It offered the largest
opportunity for growth for us and also the most room
to improve technically. We know that there
are several barriers to using Twitter on
mobile, including poor connectivity, slow mobile
networks, expensive data plans, and also low
storage on devices. So in 2017, we launched our
first iteration of the PWA, branded as Twitter Lite. It was faster,
lighter, and engaging, giving our users
the best Twitter experience at a lower cost-- hence the name "Lite." In order to serve the
global conversation, we need to make
sure that Twitter is available to
everyone, and our PWA is helping us do just that. And since then, we've been
growing Twitter's user base with the help of the PWA. Tweets sent from the PWA have
increased by nearly three times since the launch. And our users love
the PWA as well. They're each using it
for different reasons, from data constraints
to storage constraints. We wanted to increase the
discoverability of the PWA, so we decided to
list it in the Play Store, which is where our
users went to look for apps. Since it was 2017, we did this
via a WebView wrapper, which helped us achieve the
level of discoverability we were looking for and
essentially reach our users. When we did this,
the install size was much smaller
than our Twitter for Android app, which was
a huge win for our data and storage
constrained customers. We also saw over 5 million
installs of the app from the Play
Store since launch, which increased the
number of people who have the PWA on their device. So by listing it
in the Play Store, we were able to increase
discoverability, which allowed us to reach more
people and grow our user base. Listing it in the Play Store
also gave us visibility into how our users
perceived our app at scale. The reviews and ratings
across countries and languages increased our ability to find
gaps in the user experience. That's especially
important when you're building a global product from
San Francisco, like we are. And today there are a lot
more options for distribution. We started with
Add to Home Screen, used a WebView wrapper to bring
our PWA to the Play Store, and have also used PWA
builder to bring PWA to the Windows desktop. We're now exploring
using Trusted Web Activity as a building block
instead of the WebView. All these options mean that
whenever a customer looks for Twitter, there's a way
to install it and keep it on their device to help
us grow our user base. CHARLIE CROOM: So all these
distribution mechanisms mean there's even more ways
to access the Twitter PWA. And as Jesar mentioned,
we want to think about how our customers are different. But technically, we
can go one step further and think about how their
devices are different as well. Though we started by building
the mobile experience, our goal has always
been to create a richer, faster experience
for all of our users, and today I want to talk about
how we did that for desktop from a technical perspective. So this is the
traditional way that you might start thinking about
how to create a responsive experience for your users. You'd segment the
desktop users on one side and the mobile
users on the other. But this method doesn't really
capture the level of nuance that exists in the world today. Many people use physical
keyboards with their phones or live in places where wired
internet, as you might have on a desktop, is actually
slower or more expensive than their wireless connection. Instead, we thought about
our users and their devices in a different way. Instead of looking
at it device level, we broke down the
properties of their devices and treated them as parameters
into our application. And I think that this
is a really great way to think about your PWA
and how you build it. What's the output of an app
when the internet is 2G? How does usability change
when a mouse or a keyboard is detected? What about if the device
is low on memory or just doesn't have a lot of
memory to start with? Using these techniques
is one of the reasons we decided to keep Data
Saver available on the new Twitter.com desktop site. We recognize that there are
many people in the world who can benefit from this, even
if they're on a larger screen experience. Perhaps the most important tool
to help us make these changes wasn't even a web API. It was actually
a design pattern. Our awesome designers
have worked tirelessly to help us
standardize the way we use small, repeated
elements across the site, like the button you see here. And it means that any
time we're working on a new page or a new
feature, the method for implementing this is not
only very clear design wise, but it's well documented
and easy to drop in code wise as well. And what I've discovered
is that the concept of progressive
enhancement-- it really lends itself to merging
components and parameters. On Twitter, we have a ton
of floating action buttons, and these allow you to do
things like compose a tweet, reply to someone, or
create a new list. And any time we use these
throughout our codebase it's always the same
single component. So, when we worked on bringing
our PWA to feature phones like you see here or
other smaller devices, we found the floating action
button was often in the way-- it was too big, it was hard to
get to without touch support. And so, instead of
using that button, we used the smaller
action bar, and this was powered by the
extra physical keys that those smaller devices have. So I want to show you
how easy this was to do. We use React at Twitter, so
that's what I'm showing here, but you could do this with
any component-based framework. The gist is that we have
our floating action button component, and if we detect
that the user agent is a feature phone, we instead simply
render a soft button bar. And what's fun is that this
is really the code we use. We have a few more properties,
but it is this easy to alter functionality
throughout the entire website. And I think that this
is a really neat example of progressive
enhancement, because it helps the developer
make things more easily and provides benefit
to your users as well. And we use this pattern to
help us create better desktop experiences. For instance, when using
an overflow menu, on mobile you see it as an action sheet. Well, on desktop, it presents
instead as a dropdown. On larger screen
devices, we can take advantage of all
that extra screen real estate to show related
content alongside a screen. This adds on top of
the mobile experience. We can even go one step
further and show two screens side by side, like your DM
inbox and a particular message view from your DMs. This makes navigation easier
and more powerful for our users. Finally, because we've been
iteratively experimenting with desktop, we got
feedback along the way that the wide
screen design didn't take full advantage
of all the things that make desktop unique and
powerful compared to mobile. Based on this, we've
been experimenting with newer designs
that allow easier access to features customers
care about, like lists, bookmarks, and more to come. So we hope our
journey can inspire you to build a
single codebase PWA, and we have a few tips we hope
will help get you started. First, progressive enhancement
isn't just about the APIs you use. It's for the way you design,
the way you roadmap, and the way you think about your
product as well. Next, make sure to get your
core experience right first. Ensure that the code
that everyone sees is the very best
code that you write. Also, think not just
about the users, but their devices and the
properties of those devices. And, finally, use
those properties to create a responsive
experience that adapts to the diverse
needs of each user. So Jesar and I
didn't do this alone. It takes a village to
make something this large. So a huge thanks to the
entire team back at Twitter. [APPLAUSE AND CHEERING] As you might have noticed, a few
of them are in the room today, and so we look forward
to hearing from you. We really love
working on this PWA and we truly hope that
you enjoy using it. And now, I'd like to welcome
Rudra onstage to tell you more about how Times
Internet builds for their users in India. [APPLAUSE] RUDRA KASTURI:
Thank you, Charlie. That was a great show. Hi everyone, namaste from India. I'm Rudra Kasturi. I'm growth at the Times Group. I'm very excited to be here
to share Times' web success story with all of you. At Times Group,
we build products for all segment of users
as we touch their lives in every day in different ways. Some of these are just not
products, but iconic brands in their own right. Our business is large and
spread across multiple use cases like news, languages,
music, OTT-- you name it, at Times Group
we have a business around it. Now, this comes with
huge growth opportunities and unique challenges. A recent study states that
internet users in India will almost double alongside
smartphones' growth in next three to four years. But the reality is, the
majority of these users are on slow connections
on low-end devices with low storage capacity. And if those constraints
aren't enough, language is also a
key consideration when building for these users. There are over 200 languages
spoken in Indian subcontinent, with different
scripts and dialects. We have seen our Hindi
users have surpassed English and are growing at
94% year on year. This is where we have
identified a huge opportunity. As I said earlier,
at Times Group, we build products for everyone. So we focused on improving that
user experience on our Hindi property Navbharat Times,
or we local call it as NBT. NBT has been delighting
users since 1947 and today, we proudly serve
65 million users on web. But most of these users
are in small cities with poor connectivity. Keeping this in mind,
we built NBT PWA, which is fast, light, and reliable. My team contributes to
the growth and revenue for the company, so our PWA
is built on two pillars-- performance and engagement. Performance is critical
for all businesses in India and, of course,
across the world, but every second
delay on page load, we lose substantial traffic. So we have performance
budget which ensures we don't exceed
this limit on each page. We have a maximum JS
bundle size and totally [INAUDIBLE] and a
specific load time to ensure our time to
interact to always stays under five seconds on
most of the networks. And we also have a system in
place if any of this limit is crossed, we have
an electric system that triggers and
identify the issue and we quickly
implement to fix it. As an example, we use
webpack-bundle-analyzer that helped us to
reduce our JS file size by 70% over
the past few months. As a media site, we
depend heavily on images, so we used Intersection Observer
to prioritize and lazy load images, ensuring
that right images are loading on the right time. And we don't want
our users to see any blank screen or an offline
dino when they're offline. So we have used caching
strategies using Workbox so user can still consume top
20 stories on NBT when they're offline. With all the great effort,
we launched NBT PWA-- super fast, super light,
and instant loading. I love this screenshot. And we use Lighthouse
as a source of truth to measure this performance. And now, our pages
are super fast. Now, we want to ensure that
our users to stay engaged more and consume more content. Keeping this in
mind, we used Add to Home Screen prompt that works
to prompt the user when they're most likely to install,
typically during breaking news or a big event in India like
elections, budget, [INAUDIBLE] and so on. We want to earn the
love of our users, so we let them
experience our PWA first before asking them
to install it. And the best part-- our marketing teams don't
have to spend a thing. They don't have to
spend a thing here, because our average spend
to install an Android app is ranged between 4,200 rupees. Depends on the quality
of the user you acquire, which is about $1 or so. PWA installs are
absolutely free. And the biggest
achievement with this is we have driven engagement
higher by almost 50%. And, finally, we
used Web Share API that triggers the
Android need to share dialog to give users control
over how and where the data is shared. Since launching it, we have seen
increase of 24% users coming to NBT while they shared posts. With all of these, we have seen
incredible wins on NBT PWA. We saw a stunning 72% increase
in acquiring new users, and we achieve our
engagement goals by increasing the
average time spent by 31%, which means that
users are sticking around for longer sessions,
watching more videos, and consuming more content. And finally-- I
love this slide-- there was a clear
revenue impact for NBT, as we recorded 59% increase
in our network revenue. There is no magic bullet. [APPLAUSE] There is no magic bullet here. Keeping performance
and engagement as our key focus areas, we are
able to achieve these results. Also, we did the impossible. I'm sure most of you know Alex
Russell, the tech lead for PWA. When he saw NBT PWA trace,
he went and tweeted this. [APPLAUSE] Thank you, Alex. So if you're wondering where
we want to take our development effort next, with
incredible wins from NBT, we have launched PWA
in six more languages-- Telugu, Tamil, Marathi,
Malayalam, Kannada, and Bengali languages-- and across multiple brands
such as the Economic Times, the biggest business news in
the country, Gaana, our music streaming service, Dineout,
our table reservation service, and many more. We strive to be at the
forefront of web development, so we have used Trusted Web
Activities as a building block for our Android offering. Ladies and gentlemen, I'm
super excited to announce on this stage for the
first time NBT 2.0. [APPLAUSE] Attracting and
retaining app users is a tough problem for
users on low-end devices with low storage capacity. In such scenarios, smaller
apps seal the deal. Using Trusted Web
Activities, we have created a lighter experience for
the users on low-end devices. We are now able to
offer an experience that is less than 1.2 MB and five
times faster to install. You can all catch this lighter
experience on web sandbox. Please [INAUDIBLE]. And finally, I would not
have this opportunity to present these amazing
business outcomes if it hadn't had been for the team. A huge thanks to all
of them on the screen and the Google
team who helped us to achieve these results
for them behind the screen. [APPLAUSE] I would like to
fall on stage Matt from Hulu to explain PWA's
success story on the desktop. [APPLAUSE] MATT DOYLE: Thank you, Rudra. Good afternoon, everyone. My name is Matt Doyle and I'm
a product manager at Hulu. Hulu is the fastest growing
streaming service, offering live and on demand TV
and movies in the US with over 28
million subscribers. We are home to acclaimed
Emmy Award-winning Hulu original series "The
Handmaid's Tale" and Oscar-nominated documentary
film "Minding the Gap." My team's mission at Hulu is to
ensure that the Hulu experience is especially tailored
to every single device that we're on, whether it's
the TV in your living room, the computer you're
using right now, or the phone in your pocket. And today, I'm going to talk
to you about Hulu on desktop. In September of last year,
we relaunched Hulu.com. It was built from the ground
up with a brand new UI and in a modern tech stack
using Node and Next.js. And just last month, we were
awarded the 2019 People's Voice Webby Award for Best
Media Streaming Website. [APPLAUSE] As we heard from Twitter, the
beauty of developing for web is to build once and
ship to everyone. So my team's work
was done, right? Well, not quite. It turns out we didn't
quite ship to everyone. You see, we'd developed a
universal Windows Platform Application for desktop in
2015 and, since then, it's gone largely untouched. It was built on our old stack,
lacked a ton of features, didn't have live TV, and the
reviews weren't that great. But if there was one positive
that we could take away from what our viewers were
saying about our legacy app, it was that our new
website was better. At Hulu, we actually saw
this as an opportunity to try something new. And that's what I'm going
to talk to you about today. We began by asking
ourselves, why did our viewers keep coming
back to this legacy application, even though it lacked
so many features? Well, simply put,
it was installable. Hulu viewers loved having their
favorite TV shows and movies just a tap or click
away without having to go through their
browser, and we know that having Hulu
on a user's home screen drives repeat visits and
increased engagement. This is when we had
our light bulb moment-- desktop PWA. Leveraging the
fundamental PWA components would allow us to
replace the legacy app and would also allow us
to iteratively test PWA without rolling out
to all of our viewers. So where do we start? Well, we chose to start small-- a basic PWA made up of a web app
manifest and a service worker. Simple enough, right? Just two things. Well, we actually found there
were quite a few challenges in these two components. Here are some
decisions that we made that might help you when
you approach your own PWAs. The first was scope. We used the ability to set the
scope of our service worker to allow us to incrementally
roll out our PWA. We scoped the server worker to
its own path at Hulu.com/app. Then we pointed a native
app wrapper to this path. This allowed us to
seamlessly migrate users from the legacy app to
the new Hulu desktop PWA without impacting the
entirety of Hulu.com. Here's what that looks like
in our web app manifest. We plan to continue to utilize
this approach to incrementally test PWA through the
web browser as well, and it's an approach
that all of you can take to roll out
PWA to your users. Second, service
worker installation. We had to decide when
service worker installs would become effective. Since tab hoarding is
pretty common on desktop, and I know some of you are
guilty of this up here, we chose to skip
the waiting phase. Here's what it looks like
in our service worker. Choosing skip waiting ensured
that the latest version of the service worker
was installed even when users don't close their tabs. We referred to the service
worker lifecycle developer documentation to pick the
approach that was best for us. And finally, caching. The caching strategy
is going to determine what the offline experience
looks like for your users. Do you want to show them a
cached version of your home page or display something
completely different when your users are offline? At Hulu, we have
a live TV service, and it's important that the data
that we display to our users is fresh all the time. So, at Hulu, we took a
network-only approach for domains associated
with these services. This approach works
really well for items with no offline equivalent. When building your
own PWAs, it's important to select the
caching strategy that works best for your application. And at Hulu, we continue
to explore new avenues to provide the right offline
experience for our viewers without negatively impacting
the timeliness they expect from a live TV service. So now, the big question-- how long did all of this take? Well, getting to a baseline PWA
took just one developer only two weeks to research,
build, QA, and release. That's just one
sprint for my team. We literally couldn't have
done it any faster than this. [APPLAUSE] And this is what it looks like. Once installed, the
Hulu PWA behaves just like any other
application, and now it's just a tap or click away-- no need to sift through
a forest of tabs. And we were able to deliver
this experience to our viewers with very little effort and
consolidate another codebase in the process. Now, when we ship a
feature on Hulu.com, we can say we can truly
build once and ship to everyone on desktop. And since launching the PWA in
January, it's been doing great. In just three short
months, we successfully migrated 96% of all of
our legacy app users to the new Hulu PWA. We saw a 27% increase
in return visitors and a 5.5% increase
in engagement. But I'll tell you,
the best thing was that our viewers
are loving the app. At Hulu, we care about every
single one of our viewers, and feedback like this is
better than any other KPI. Discoverability of desktop
PWAs has never been easier. Current Hulu subscribers can
try the PWA today by visiting Hulu.com/app using Chrome. Simply click on the Add to
Home Screen prompt to add Hulu to your computer. And soon, you'll be able
to add PWAs directly from the omnibox in Chrome. All of this has given
us the confidence to invest further in
PWA technology at Hulu. And, in the coming
months, we're going to be adding support for
push notifications, media keys and media session API,
and an enhanced offline experience because,
although we all love trying to beat our
high score in the dino game, we think that we
have an opportunity to provide an even
better offline experience for Hulu subscribers
enabled by PWA technology. We're going to use offline
as a way to drive awareness for the latest Hulu
original series, and we're going to experiment
with offline media caching to provide trailer playback
even when a user doesn't have an internet connection. At Hulu, we are just
getting started with PWA, and we look forward to
bringing all of these features and more to our viewers soon. And finally, I wanted to give
a big thanks to the entire Hulu web team, without
whom we couldn't deliver this amazing
experience for our viewers. Thank you all so much, and
back to Aanchal to wrap it up. [APPLAUSE AND CHEERING] AANCHAL BAHADUR: Summarizing
months of hard work in just 10 minutes is no easy task,
so as a measure of how amazing they are, can you please
give them a loud cheer and a huge round of applause? [APPLAUSE AND CHEERING] Lighthouse score 1,000. I'm sure you've been
listening intently for the past 30 minutes. That was a lot of
information, and so I'm going to quickly recap for you. Take your phones out,
take photographs, and if you're watching us on
the livestream, screenshots. Twitter showed us that,
by building a responsive experience in one codebase,
you lower development costs, you create engineering
velocity, and you increase the number
of tweets that they had sent by almost three times. This is a direct business
outcome for Twitter. Times builds for the
next billion users. With a laser sharp
focus on performance and a tracking
system that breaks if you don't hit that
100 on Lighthouse, they've successfully earned
the love of their users. Across different
languages, their PWA has contributed to 59% increase
in ad network revenue-- a direct business outcome. And, finally, if
there's one thing you take away from
what Matt said, listen to what your
users are saying. They might be giving
you some feedback that might really be
helpful for you as you make development choices. So look at your
legacy apps, some that you might have
ignored for a while. Use the web super buzz, and
create delightful experiences just like Hulu's PWA on desktop. It's still early
days, but Hulu's PWA is loved by their
users, and they're seeing an increase in
27% for return visitors. And engagement is also on the
rise at about 5 and 1/2%-- it's just been a few months. These are direct business
outcomes for Hulu. And, finally, as a user,
it's not that I don't care. I trust you to make
the right choices so I can have a
delightful daily routine. I can continue asking
profound questions. So thank you very much. Take a look at your business,
see how PWAs can help you. We've got material when
you're ready up on web.dev, so this is a good one
to take a photograph of. Or did your site,
Lighthouse has your test against various benchmarks, or
