What do you use for Chrome Extension usage tracking?

• About the usage, I can't answer, because for my extension, I don't track with GA (they need to signup to my plateform before, and then, I track their usage)
• For the installs, google is providing enough stats, you need to add your google id in the extension options, and then, you can filter via google analytics where the installs are from. (like installs from the extension chrome page, or via the search results....)

Most traditional web analytics tools’ JavaScript snippets are actually just wrappers for creating complex image beacons, which means you can use code to send the information you need without using the traditional JS snippet in a fashion a little closer to a straightforward GET call.

What does your extension do? The kinds of calls you’d want to create are different depending on whether your extension is, say, a Honey clone or a pop-up language dictionary.
