 Hi, everybody. So I want to give a great shout out to Katie O'Connor and our marketing team who put together that video. So you did a really terrific job really reflecting kind of the state on what we want everyone to be building today. So I'm Tal Tran. I lead global product partnerships for Chrome and the web platform team. So that's just a fancy way of saying, I basically get to talk to all you guys and talk to a lot of different companies and sites about being early adopters of all these new awesome web technologies. So it's great to hear from Darren and get a state of where Chrome is and the overall web platform. And now I get the opportunity to tell you more about progressive web apps and what's happened over the last year. So I did a lot of reflecting the last couple of days. No, no, no, not about the other stuff. But really about kind of where were we last year at the same event? And so I went back and looked at some of the tweets coming out because the Flipkart team had just launched their progressive web app. We're really kind of pioneers in this space. There's a lot of buzz and excitement about what's now possible for the web. I really want to echo Darren's sentiments about the emerging markets really leading the way here in terms of constraints leading to a lot of innovation. But I would say I was a bit nervous about the success. And I didn't know whether it was going to be specific to Flipkart, the region, will progressive web apps actually extend to other verticals and markets. And I wasn't sure if this was going to be a hot thing for a minute and then it would just get shelved away. And so it got me thinking a lot about toys. So this is my son. And so he recently got a gift of refrigerator food and wanted me to build a refrigerator. And so I spent two hours painstakingly going through building custom shelves so that every single piece actually fit. So all the pieces actually fit across all of these shelves. And I think most parents in the audience would know that most toys last about a week because it literally got shelved and empty and he didn't really play with it anymore. And I wondered would progressive web apps actually have the same fate? So was the Flipkart progressive web app a unicorn? And thankfully that wasn't the case. And so Flipkart continued to invest in progressive web app technologies. Actually just did a big refresh of their site. They also extended it to their desktop. And they had tons of learning this past years. They battle tested progressive web apps. In fact they just went through big billion days which is the biggest shopping event of the year for them in India. And last year the event was app only because they had shut down their mobile website. And this year with the Flipkart live experience back and the web experience back they saw as much traffic on the web on mobile as they did on desktop. So it completely affirmed their commitment to bringing the web back on mobile. And I think beyond Flipkart and the progressive web apps we wanted to see if we were starting to see momentum in the overall marketplace. We started to see that progressive web apps organically came up as a topic at various conferences. Saw a lot of articles about progressive web apps. I have a Google alert letting me know every time someone mentions progressive web apps sometimes I get flooded. And I want to point to kind of three articles that really illustrate that progressive web apps is actually broadening across all industries. So Smashing Magazine wrote a beginner's guide to progressive web apps. A few months ago Business Insider wrote about how PWAs are blurring the lines between mobile and web. And then more recently Marketing Land which is targeted at digital marketers talked about how the progressive web apps could be kind of the next biggest thing. And so it was really terrific to see that both developers and marketers are all interested in these technologies. So Darren talked about the importance of your web audience being a worldwide audience. And we've seen tremendous interest from developers globally. After a progressive web app Dev Summit in Amsterdam this past June, we held viewing parties across the world. And so these are folks who actually came to actually watch together with other Googlers and with other developers in the region. 17,000 developers showed up across 35 countries to showing the enormous momentum and excitement for wanting to build with these new technologies. And my favorite tweet was that there was a viewing party in Bangladesh where there were over 310 Ds and they were so inspired that they actually formed a human PWA and then tweeted this out. So definitely my favorite tweet of all time. So we're seeing global interest from sites large and small across many industries building progressive web apps. And so I wanted to kind of take a moment here and just kind of talk to you about kind of what exactly is a progressive web app and then really tell you real life partner stories so that you can kind of maybe get inspiration for how you want to go about approaching it at your respective companies. First of all, it's amazing to see the term progressive web app take a life of its own. We really view it as a shared definition across the entire web ecosystem. And it's great to see folks in the community continue to contribute to what is a progressive web app. And so we wanted to offer kind of our definition but obviously evolve it to what makes sense for your site. And ultimately it's about radically improving the web user experience. Probably just saw this in Darren's talk where we wanted to make sure that you understand that your PWAs are first and foremost about improving your user experience, making sure it's fast, reliable, engaging for all users. And a common question I get is, wait, does that mean I have to build a native app, a PWA and a mobile site? And the answer is no. Your web experience should just become your progressive web app. And so that also means that your progressive web app should be indexed and crawlable just like any other website. We've also got a lot of questions about this as well. And so I wanted to just note that we just posted an updated blog post from Webmaster Central Blog where we talked about updated guidance on building indexable progressive web apps. So definitely check that out. I think it just got posted yesterday. And so we wanna let people know that building progressive web apps is a journey. And so we wanted to just maybe offer up some of a framework for how to think about building a progressive web app because people sometimes think, oh gosh, it feels so inaccessible. There's just like, there's so many things I have to do. And so we wanted to say, you know, think about it as a journey. You can start off with a baseline with things like HTTPS, a web app manifest file, and a few other things. And then continue to add on more and more features over time. And so an exemplary one is about pushing your site to add more features, get even faster loading times, provide a more reliable experience offline, and even on flaky networks. So the good news is that you don't have to track all this up because we actually heard your feedback and we put together a baseline and exemplary checklist of things to test and fix. It's on developers.google.com slash web. You're gonna hear that over and over again because we're really trying to be better about having a central Google resource for building on the web. And Darren already talked about Lighthouse Tool. And so really think about it as your personalized guide for a site to becoming more progressive. We're continuing to invest in Lighthouse and it will get better. So with the checklist, Lighthouse, along with testing on real hardware devices, you should be on your way to shipping a great PWA. So I'm not gonna spend this talk going into detail about Service Worker and all the various APIs. There are a ton of great advanced sessions about that. But I now wanna dig into the impact of Progressive Web Apps and why it's a big deal for your users and your business. So I've had a really fortunate opportunity to work really closely with a number of partners across the globe. It's been awesome to have folks actually share stats because they want to kind of contribute back to the ecosystem and talk about the awesomeness of what they're experiencing after they've shipped a Progressive Web App. So I wanna run through a few Progressive Web Apps in different stages to really illustrate the diversity of approaches, regions, and industries. So Darren talked about Alibaba, which is the world's largest speed-to-be marketplace. So the scale at which they're operating is huge. And he went over how they saw a 76% increase in conversions. So I wanna add one more detail because conversions is great, but you really want to make sure that users are coming back to your site time and time again. And so I wanna talk about how they saw an increase on iOS of monthly active users, as well as a bump of 30% on Android. And so the higher increase on Android could probably be attributed to the fact that their open rate on web push notifications is comparable to their native app. Again, just increasing the overall reach of your user base. And housing.com is this major, growing online real estate platform in India. So seeing incredible activity and innovation coming out of India with Flipkart and then startups like Housing Embracing Progressive Web Apps. And like most startups, Housing is obsessed with how to efficiently acquire users to gain market traction. This is probably not something that developers think about, but I bet you your marketing team is thinking about how to bring in new users and how much they cost. And so Housing took a look at how much they were spending to acquire an app download versus getting user to come to their mobile website. So the first that I wanna offer is I cost them about $3.75 to get users to download an Android app. And how much do you guys think it's costing them to get users to their mobile website? 75 cents. 75 cents, 80, 50, seven cents. So I wanna pause on which to observe the difference here. And how much cheaper it is to get your user to your mobile website. So maybe worth saying, well, app users are usually more loyal, so it may be worth it. But for that single app download, you can reach 53 mobile web users. So that's 53 potential re-engagement opportunities. And Housing is operating with millions of users, so obviously trying to get more users to their website efficiently is a no-brainer. Yeah, people should take pictures of this and send it to your marketing team. But it's not only about getting users to your site experience, you want them to make sure that they're getting a really good user experience once they arrive. So Housing was seeing faster page loads as well as an increase in conversions. And the Housing folks are actually here, they traveled in from India and are giving a talk tomorrow morning. So definitely check it out. I believe it's the second talk of the day. So now I wanna turn to West Elm. We've seen a lot of adoption in other parts of the world, and so we're starting to see more and more here in the US. And so West Elm is this modern furnishings company, and it's on its way to doing about $2 billion in revenue. And a significant portion of that is actually coming from online. They don't have a native app, so they rely on the web to deliver the best user experience possible. And as you can probably see from your own habits, you're seeing a growing number of users shopping on mobile devices. So we're gonna queue, so I'm actually gonna demo an early beta that they just launched yesterday. So I already have it on my home screen, and so one of the key principles or tenets of them launching this was that they wanted it to be a hugely immersive experience. And so here you're dropped right into this West Elm experience. You can scroll, everything's super smooth. You see the navigation on top. They took a lot of cues from social applications, so it's highly visual. So I can tap in here, see how smooth everything looks. And I actually wanna go through an example of when I showed my sister a desk I just bought from West Elm. And so instead of me kind of searching, I just look and say, oh well, I can just go ahead and just tap. I look at furniture. I see home office, desks. And as I'm scrolling through, I see, oh, there it is. There's the desk I had purchased. And this is actually how I showed my sister the desk I bought. Very much like a magazine like experience. And so this is the type of user experience that we're hoping all of you are inspired to build back to sites. And so this is where focusing, we talk a lot about performance and making sure that your site is super fast. But I think we really think of West Elm as a great example of how to rethink your user interactions for today's audience, which is about casually consuming and being inspired by things. Maybe the user is not gonna purchase every time they come to your site, but maybe they wanna come back and just browse in their few moments where they have some downtime. So you can check out their early beta at the URL there. And I wanna kinda now turn to Latin America. So Infobay is one of Argentina's first major digital-only outlets. It's a top publisher with a strong presence throughout Spanish-speaking Latin. And we're actually starting to see growing interest in Latin America for all these new web technologies. Infobay's primary motivation was speed and delivering news to users as quickly as possible. And it's no surprise. 65% of their traffic is on mobile. And so they took inspiration from the Washington Post progressive web app demo from IO and they started working with the post team and leveraging the Washington Post CMS to really roll out their progressive web app. And we're seeing that the Infobay's article pages are loading in less than a second. They're also caching content for offline experience. And so similar to what you saw with the CNET demo from Darren, this is really about a smooth reading experience and really what news should be and be resilient to flaky networks as well. And then I wanna talk to you about Lyft. So we've seen adoption with retail and publishing sites and it's great to see another use case here. So for those who are unfamiliar, Lyft is an on-demand ride sharing network. It was app-only for a long time. And so they wanted to make sure they could reach users across all platforms. And obviously we've seen that reach and user acquisition are critical. So they rolled out an MSI. I think there was an article about rolling out their MSI for the first time a few weeks ago. It wasn't a PWA yet, but it was just an MSI just to test the waters. And they had some internal metrics that they were looking at. And after a month, they saw five times more rides than expected coming through their mobile web. So it turns out that people were probably wanting to book rides even before they're able to download an app. So here's a gift of their user experience. And so after they saw that initial kind of success with their MSI, they went all in and said, you know, we're going to invest in mobile web. We're going to build a progressive web app. And so their goal right now is to achieve feature parity with their native app. So they launched in preview yesterday, ride.lyft.com, and the team will continue to iterate and add more and more features over time. And so this is about making sure they can deliver a great experience for all users regardless of what platform you're on. And so, and they didn't want to actually have people download an app if they didn't need to. And here I want to point out that they're trying to achieve feature parity by also dramatically reducing the download size. They were gracious enough to share some of their stats around, you know, 17 megabits for Android. You see the bump in iOS there. And their progressive web app is less than one meg. And so the Lyft team is actually here and will kick off tomorrow morning with housing as they deep dive into how they're building a progressive web app and the benefits of being able to deploy updates and experiment quickly for the web. So kind of the final one where I want to talk about stats a little bit is to make my trip. So we're going back to India. And make our trip is the largest, well, one of the largest travel sites in India. And what's interesting here is to make my trip folks really start digging into kind of differences in user behavior between the native experience and the mobile web experience. And so for those of you unfamiliar with the India market, like up to 90% of users will uninstall the app in six months. And so for an infrequent purchase like travel, it can be hard to remain on the user device. So after being in a market for a few months, so they share some insights about what they're seeing in terms of their user base. First of all, half of their bookings on their progressive web app are same day reservations. And not only are they same day reservations, but this number is actually 30% higher compared to their app users. Turns out that these are generally last minute users. They just want to book right away and they prefer to do so on their mobile website. You probably are experiencing the same thing. Like when you want to get something done, you just want to get it done. You don't want to have to wait for a download. And the other fascinating stat is that in taking a closer look at first time visitors, it turns out that their progressive web app users were booking three times more on their first visit. And so this really shows the web is great at fulfilling the immediacy of intent, which is in this case, resulting in more bookings. And so they're also seeing that the destination cities of progressive web, the destination cities are much more widespread for progressive web app users versus native app users, indicating that people might be booking once they arrive on site and they just want to get a booking done as quickly as possible. So really terrific staff and really kind of giving us insights into the different user behavior. And so they still have a native app experience and that will address and be great for a specific audience but then they're also building a great progressive web app experience. And so I just want to make sure that, I talked a lot about a bunch of these companies seeing worldwide adoption. And now I wanted to spend just a couple of minutes talking about how to get started. So you know, have an idea of what you should be building and you can see that it can have high impact on your business but the toughest part is figuring out how to get started, especially if you're part of a large org or you need to deal with a lot of legacy issues. And so you have to take a look at your different user experience and figure out what you want to tackle first. Sometimes you can tackle the entire site, sometimes you can do a section like CNET Tech Today, they did, they ended up shipping a progressive web app for a section. And if you're a larger brand, sometimes it's easier to start with a smaller site to become familiar with the technologies and then extend out to your flagship. So here I want to walk you through a journey that the Weather Channel has gone through over the last year and I think many of you will relate. So weather.com is a top 20 site here in the US delivering billions of forecasts around the world across many, many platforms. And weather is really focused on innovation and new technologies and became really interested in seeing how they could build a much better mobile experience. So their journey started about 18 months ago where they had to diligently roadmap what they need to do and knowing that it will take time. They're a major site operating in almost 200 locales. And so they had to prioritize, I think most of you are figuring out how to prioritize transition HTTPS right now or if have not already done it and we have a great session later talking about HTTP too as well. And so it wasn't easy with ads and analytics but notice it was starting to get easier as more third parties were prioritizing HTTPS as well. And then in April, they actually rolled out web push notifications across 30 languages. What's significant here, and it's actually now 62 languages because they've continued to expand, what's significant here is in the first three months of rolling out web push notifications, weather saw a million opt-ins. So they provided the same set of notifications as their app users for the web but now they're reaching a whole new audience with web push notifications. And then more recently, they started looking at integrating service workers and transitioning more of their sites over to a progressive web app. Given the U.S. site was more complex and with more legacy, they decided to tackle their international sites first and have now rolled out progressive web apps in 178 countries seeing growing traffic in China, India and Mexico. And the weather team is constantly trying to improve their overall experience. And they've been happy enough with working with these technologies and seeing some gains here that they are planning to expand to a progressive web app for their flagship U.S. site in 2017. And I think I really want to tell the story because I think we hear a lot about, well, I can't do it in the next three months. We can't figure out how to prioritize. But I think given some of you who will have legacy sites, like you need to take a step back and kind of roadmap out how long it's going to take and what it's going to mean, it's not something that's going to be done overnight. Think about it as a journey. And so I wanted to kind of maybe walk through kind of the approaches to building progressive web apps. And I've offered up a diverse set of sites at how they start building PWAs. And so we started just noticing patterns in how people are approaching it, right? So some folks are lucky enough to just build new from the ground up and transition their experience almost immediately. Some people will want to ship a beta to kind of test and experiment, rolling out to a small percentage of traffic with the intent of transitioning their main site over time. And then some people are able to actually build on their existing experience. So integrating APIs indirectly. And so housing and CNET are actually two examples of where they were able to build new experience from the ground up. And I think they are, that was the right approach for them. Housing for the whole site, CNET for a subsection of their site. And for the beta, as I talked about with the demo with West Elm, they couldn't transition a site right away. It was going to be, and it was tough to describe what this experience could be like. So even before they got to a beta, they actually built a demo and then they showed it to their senior leadership. And so now they are going to move to a beta, early beta by the end of the year and then a public beta next year, which is a great path. And then they'll start to kind of move their site over over time. And left again is an early preview this week and they'll continue to iterate and bring more and more features to their PWA. And as far as existing sites, I already talked about the weather channel, but make my trip actually started first with their hotel section of their site. And then they expanded to flights and now they're going to continue to add other sections to bring into kind of the progressive web app fold. And so there's no right way or wrong way to build a progressive web app. I just wanted to offer kind of a framework as you're kind of going back to your teams and saying, okay, section, whole site, new beta existing, just so you can get the conversation started in terms of how to start building. And so looking ahead, there's going to be tons of great sessions today. I want to kind of talk about how progressive web apps really is, we talked a lot about kind of engagement, conversion, we don't need to know like all the marketing terms at the bottom, but kind of think about progressive web apps as kind of this term for just improving your mobile web experience. And then accelerate mobile pages. This is also great. If you're having a lot of traffic coming in from search and other platforms, it's a great way to get users quickly to your site from the top of the funnel. And we're going to have an AMP and PWA session tomorrow morning where we'll talk about AMP installing a service worker to transition to a progressive web app as well as how AMP is being used inside of a progressive web app. But we get a lot of questions about that. And then for some of you push notifications, it's like the one thing that you can do over the next few months, that's perfectly fine. You're able to re-engage users so quickly like what Carnival did in what Darren went through. And then two things I did want to highlight which are actually after my talk this morning. Conversion is such a pain point. Typing is so painful on the mobile web. And we've done ourselves a disservice by not trying to do more here, but we are now. And so seamless sign in and one tap checkout are going to be great sessions where you can basically just understand your get users into your experience, build an engaging experience, and then make sure they actually convert and close on them. So it's really about radically improving the overall web experience. So over the last year, we've heard from so many of you the excitement for building and innovating on the web. And again, this really is a journey. And it requires constant iteration, probably patience as you're trying to figure out how you're gonna construct your back end to fit in with the progressive web app architecture. But it's worth it. And I hope you see that today by just seeing the enormous momentum and what people are seeing in terms of success with their various business metrics. And so speaking of iteration, I talked in the beginning of building a fridge for my son that didn't really stick. So I did try again. So this is actually a hotel room key because I was traveling a few months ago and he was really upset that he couldn't be in the hotel room with me. And so I built, I took a shoebox and then I put a little hotel, the slit. And then he was able to, I bought my hotel key and now he uses it every single day. He literally closes his door, puts in the key card, beeps and then lets himself into his hotel room. And so he does it every night. He's been doing that every night for the last few months. And so with that, I think that's your inspiration for building great web experience that people will want to use every single day. Thank you.
