Having built many Chrome Extensions in recent years and accumulating more than 20k users, as well as helping customers build their own, we've developed a simple pattern to reduce your time to release and make sure your extension is approved.
This guide is a bit technical, you'll need the help of a developer for the following step.
Source code
Complete source code on Github.
Following the Readme you should have no difficulties building your own Chrome Extension.
Remember to keep it simple and most of the code on an API to avoid debugging or releasing new versions of the Chrome Extension, as it always has to pass a review from Google.
Store listing tips
Make sure to thoroughly fill in the Store listing!
The most important section in inside “Privacy”.
If you followed our coding tips and only require the minimal amount of permission, you shouldn't have any difficulties passing Google's review.
They do read the code, don't get crazy :)
To update your Extension you can just change the version inside the manifest.json file and zip it, then click on "Upload new package" inside on the Menu > Package
