Notes de l'éditeur

  1. Dir. Of Products at Yottaa Web Performance and User Experience Optimization Service 15 years building and tuning apps and websites from various angles
  2. PHILOSOPHY – Prioritize Mobile Context Reach more people (77% have mobile, 85% sold in 2011 have browsers) Focus on core content (what to do with 20% of screen available?) Innovate – new technology CONVERT – more mobile devices than people this year, restaurants convert 90%, 64% w/in the hour By the end of this year there will be more mobile devices than people http://mashable.com/2013/02/06/mobile-growth/?__hstc=28181411.2b94e1c1b807545f894e9da17dcc240b.1380296215268.1380296215268.1380296215268.1&__hssc=28181411.1.1380296215269 Mobile searches related to restaurants have a conversion rate of 90% with 64% converting within the hour. (Source: xAd and Telemetrics, 2012) - See more at: http://www.digby.com/mobile-statistics/#sthash.ZACPqe1r.dpuf
  3. WHO has a mobile site? You ALL do You need to act accordingly WHY…? http://queue.acm.org/detail.cfm?id=2510122
  4. http://www.comscore.com/Insights/Press_Releases/2013/5/comScore_Reports_Q1_2013_Desktop_Based_US_Retail_ECommerce_Spending
  5. The AVG. SPEND on mCommerce sites is $65K this year plan to spend an average of $65,000 on mobile this year - See more at: http://www.digby.com/mobile-statistics/#sthash.ZACPqe1r.dpuf
  6. Challenge SHALLOW NOTION you can shrink desktop site Mobile-optimized is real More than screen size Remove convenient assumptions Networks shaky Device capabilities vary On-device app versions fragmented ACCOMMODATE most difficult (MOBILE) first
  7. USERS ARE NOT PASSIVE – Maybe passive aggressive Shrink a site = shrink conversion potential
  8. Numbers speak for themselves * 70% of users abandon shopping carts, huge $$ spent on retention Smartphones convert the worst – why? Smallest viewports Greatest fragmentation Highest impact from unreliable networks
  9. SO how does your app behave? How many use an APM solution? How many use RUM? How many have a dedicated group to manage performance YOU SHOULD TEST – And this is the PERFECT opportunity
  10. Mobile users expect a site to load faster 4-8 seconds For sites slower than 5s, users spend less time on ads, maybe 1sec
  11. So if global cart abandonment is 70%, perception is 15% slower, you will struggle NOTE: Mobile abandonment numbers suggest more patience, but this is changing Fun fact: research shows that rodeo riders are one of the (if not THE) only professions to consistently guesstimate time.
  12. Conceptual reboot Design for smaller, limited devices Be smart about images Implement intelligent code – RWD (we’ll talk more) Respond to device capability – enable more when it will benefit users Implement what you can afford to maintain (old browsers, variable experience, more testing, more $$)
  13. Dec 2009: 12% mobile Dec 2010: 24% (next, launch mobile) Dec 2012: 42% H112 – H113: 90% increase in mobile conversions! 275% increase in traffic Revenue per user > 70%! Mobile revenue 538% increase! Non-phone: 17% conv inc., 25% revenue inc, rev/user inc 17% http://www.internetretailer.com/mobile/2013/01/28/fathead-dives-head-first-augmented-reality-and-responsive
  14. Existing investments may already constrain budget * How much do you spend on your website solutions? * Mobile solution CANNOT be additive, must be aligned
  15. Objective drives your choice/decision
  16. TEST a market oppty Easily roll out new features (vs. app) Target market starting to use tech – Samsung GS4 Easy Mode folks Tracking user behavior Retailers’ apps with store mode gather five times more engagement. - See more at: http://www.digby.com/mobile-statistics/#sthash.ZACPqe1r.dpuf
  17. LinkedIN – saw users spending more time on site Surprised to find that devices running out of memory! It’s ideal to keep rendered content for instant switching back. However you could only do that if memory management is done optimally. There’s only so much you could keep until the app crashes running out of memory.
  18. Mobile redirects are exceedingly common Challenge SEO - Google penalizing sites for poor m.site optimization Challenge CRO - converting is harder when the experience is poor potentially EXPENSIVE Tools: multiple domains, DIY, framework plugins Figuring it out: User Agent Switcher, Ayima Redirect Checker
  19. Common differences between RWD and .msite is content & features m.site typically a subset of content Assumption "mobile users want access only to content that is “important” to them." Sure to alienate and frustrate Studies found the content users were seeking was the same, regardless of device
  20. Responsive Web Design articulates how to adapt a website’s layout for multiple screen resolutions. Creating a responsive web design utilizes: Fluid grids that ebb and flow with a devices’ screen size Flexible images and media that keep content intact on any resolution Media queries allowing designs to adapt by establishing dimension breakpoints
  21. Scaling up versus scaling down ensures message, content and functionality remain intact Scaling down risks core message and functionality getting lost
  22. For RWD, “designing to the extremes.” Either mobile first, OR Start by designing the desktop version of the website. Work out typography, tone and overall visual direction — as well as layout Small screen or “mobile” version, using the same visual direction, but adjusting the layout as appropriate for the smaller screen. Visual examples of the two layouts of the website that will vary the greatest — the biggest and the smallest screen versions of the design. These two examples will guide me as I begin the website’s front-end development. Image: http://media.smashingmagazine.com/wp-content/uploads/2012/11/envision-extremes.jpg
  23. Optimizing for everything is impossible
  24. There’s an ALIGNED concept in mobile design and mobile first, and that’s PERFORMANCE. Why is this important? Because of how websites and web applications have changed Over 200 versions of os/browser Over 30 combinations of mobile OS in the wild Strategically decide what target devices and browsers for which to optimize.
  25. Using site analytics can help you understand your audience better can be misleading (they might rely on JS, they don’t count impatient visitors that don’t ever wait for your site to load, etc) BETTER perf = HIGHER conversion Google’s Quality Score impacts cost/click, and speed impacts QS you must research your audience to gauge what best to optimize for. Focus on known devices and screen sizes (phones, tablets, desktops). mobile-first established the baseline for our website’s CSS.
  26. 7% drop in conversions for every 1 second of latency
  27. Let's talk about a necessary evil - the cost of doing business? CoreMetrics, Optimizely, GetSatisfaction, LiveChat, Marketo Show us where users've been, how they're behaving, but ruining their experience Some companies are ripping out 3rd party javascript to get performance back Consider delay or lazy loading Social Last year, only 12% of consumers bought anything through social media - See more at: http://www.digby.com/mobile-statistics/#sthash.ZACPqe1r.dpuf
  28. MYTH 2: total size of assets for mobile will be smaller than desktop. MYTH 2: The total number of http requests for mobile web will be smaller than those delivered to desktop web.
  29. Fonts usage — old version of Typekit that downloaded SVG fonts on iPhone. These font files made the mobile version much bigger than desktop. Retina images — Sometimes, both the mobile images and the retina mobile images are getting downloaded for a double hit. HTML5 Audio — HTML5 audio is embedded on the page. The browser is downloading the full mp3 file regardless of whether or not the user presses play. This balloons huffduffer.com from 122k on desktop to 2.9MB in Mobile Safari. HTML5 Video — Mobile Safari starts downloading a portion of the video in order to validate the video will work and to grab a scene from the video to use in the player. Desktop Safari wasn’t doing this.
  30. Images are stilly typically the worst offenders
  31. Consider a tip for mobile retina images - in most cases you can avoid bloat http://mobile.smashingmagazine.com/2013/05/29/the-state-of-responsive-web-design/
  32. Pageviews per visit & time spent on the site per visit have increased by 30% We’ve seen a 30% increase in conversion rate since optimizing our site – a very significant increase. That’s a very real figure indicating more sales & money in my pocket.
  33. Analyze & Determine Mobile Needs Get to know your content & your users Either Give mobile first a try Specifically rev your site with mobile in mind Optimize Images & Rendering Evaluate 3rd Party Javascripts ITERATE!
