Don't lose user and app state, use Page Visibility API: http://bit.ly/1Lr81Sv.

Counting on pagehide, beforeunload, or unload events to save user data, app state, beacon your analytics, etc? Well, I can guarantee that you're missing a lot of mobile sessions, because those won't fire whenever your app/tab transitions to a background state. You should be using Page Visibility API.

Tracking Complex Interactions in Dynamically Added Cross-Domain Iframes /via +LunaMetrics  #measure   #analytics  

"Welcome to part three of our series on tracking user behavior within iframes. In Part One, we discussed how to track simple user interactions within cross-domain iframes by using the postMessage API. In Part Two, we discussed tracking complex interactions when the iframe in question is on the same domain as the parent frame. Today, we’ll be tackling tracking user interactions cross-domain when the iframe is added dynamically using JavaScript."
Learn how to track interactions with cross-domain iframes seamlessly in your Google Analytics. Part 3 in our comprehensive iframe series.
