How long will users stay on a web page before leaving? Study after study confirm: Not very long. First ten seconds on the web page are critical for users to decide should they stay on the web page or leave completely.
This happens because performance IS user experience. Take mobile websites: 85% users of the mobile website expect it will load more quickly than on desktop. This, combined with the fact that more than 60% web page views are coming from mobile, leads to the conclusion: mobile webpage performance optimization should be taken into consideration from the beginning.
The average mobile website page weight is ~50% images. Toss in the complication of thousands of differently sized screens, and it might appear that efficient delivery of images to every device is an impossible task. But all is not lost! In this talk, we’ll examine strategies to send the perfect image to every device, ensuring a fast, beautiful rendering of your content. We’ll look at progressive images, placeholder images, lazy loading and other techniques and real world examples that will improve the usability of your site or app. Attendees will come away with an understand of the current ‘state of the art’ for optimizing visual content on the web.
