Web & Mobile @jcemer
I work on GloboPlay. globo.com
This talk is about two important subjects and their intersection.
None
None
Mobile devices are dominating the Internet.
Companies should focus on a mobile- first approach for
their websites.
https://speakerdeck.com/jcemer/
1. Mobile Web versions
Facebook and Google are trying to filter and classify the
Web.
None
None
None
None
Instant Articles are a new way for any publisher to
create fast, interactive articles on Facebook.
None
None
The average load time was between 0 and 300
ms, compared with 3.66 seconds for similar web articles.
No ads can appear above the fold. This would help
with rapid initial loading.
The biggest mistake we’ve made as a company is betting
on HTML5 over native. @Zuckerberg, 2012
The key to Instant Articles' functionality is the strictly formatted
HTML5 which is optimized for faster loading.
https://developers.facebook.com/ docs/instant-articles/reference/
None
37% + reach 22% + shares 83% + Likes 57%
+ link clicks. https://blog.hootsuite.com/started-using-facebook- instant-articles/
As with any publishing platform, the value of Instant Articles
greatly depends on your business model and goals. https://blog.bufferapp.com/facebook-instant-articles
Users won't have to click out of Facebook to view
an article.
None

AMP-HTML is simply HTML5 with a set of specifications (requirements
and restrictions).
https://github.com/ampproject/amphtml
None
The big players are trying to restrict and split
the Web.
None
AMP and Instant Articles create different versions of a same
website.
2. Mobile Apps
None
None
No-one is going to install an app for each service,
your mobile Web experience has to be good.
None
Deepest engagement for the longest period of time happens in
Apps, so Apps matter. http://venturebeat.com/2015/09/25/wait-what-mobile-browser- traffic-is-2x-bigger-than-app-traffic-and-growing-faster/
Native apps might survive.
Progressive Web Apps
Progressive Web Apps have the reach of the web, and
are reliable, fast and engaging.

1. Deliver a Mobile-friendly design™
None
None
<meta name="viewport" content="width=device-width">
@media screen and (max-width: 1000px) { /* Styles */
} @media screen and (max-width: 560px) { /* Styles */ }
None
Designing in the browser allows the designer to keep checking
the results in different devices.
None

2. Apply progressive enhance
The app should works for every user, regardless of browser
choice.
Responsive Design != one size fits all. @Brad Frost
Don’t get hung up thinking that media queries are the
only tool in your toolbox. @Brad Frost
I work for Booking.com, and we support IE 7, and
I use flexbox. @Zoe Mickley
Start with the content and then enhance the experience.
Modernizr tells you what HTML, CSS and JavaScript features the
user’s browser has to offer. https://modernizr.com/
None
@Brad Frost
3. Ensure fast page load performance
0.1 second reacting instantaneously. @Jakob Nielsen, 1993
1 second user will notice the delay.
10 seconds users will want to perform other tasks while
waiting.

4. Use a secure network connection
HTTPS ensures that the contents of communications between the user
and site cannot be read or forged.
None
The page that's making the Geolocation API call must be
served from a secure context.
https:// letsencrypt.org/
5. Create a manifest.json
Manifest enable add to homescreen and a launch experience
more comparable to native apps.
None

6. Allow the app to be loaded on offline/flaky connections
None
Service workers allow good caching strategies.

PWAs can also benefit from push notifications, like
native apps.
None
None
https:// pwa.rocks/
PWAs are in equal parts new Web APIs, design patterns,
and marketing fluff.
The Web still matter…
Thank you! @jcemer
