Lazy-loading images below the fold

Sometimes there’s no need to load all the images right away. We’ll look at the best techniques for lazy-loading images that fall below the fold.

Working with different cache sizes on mobile

Mobile browsers have different cache sizes. We’ll talk about what this means for mobile WPO.

Preloading content for the next pageview after the onload

Take advantage of the time while the user is reading a page and start downloading the next one.

When to inline and outline CSS/JavaScript

Connections are more expensive on mobile devices. This changes the numbers for when you should inline or outline your CSS and JavaScript.

Knowing the effects of iframes on mobile

Iframes are typically bad for performance. We’ll compare how iframes act on mobile vs. desktop.

Evaluating the various tradeoffs with mobile

WPO is a series of tradeoffs. In this talk, we’ll talk about some of the tradeoffs that are specific to mobile.

Understanding loading indicators on mobile

Loading indicators are important for giving feedback to the user on how the page is loading. We’ll look at how mobile browsers handle loading indicators and how you can work with them.
