I recently published a Chrome extension (Source Code) and now discover some broken incoming links on the extension's website which must be related to that extension:
On the chrome extension webstore I don't find such links. Do you have any idea where those links come from and what's their purpose? Would users exepect anything else than a 404 on that URLs?
The website is referenced in the extension's manifest homepage_url field and on the webstore item in the "Websites" field.
Update: I just noticed again one such request where the referer comes from this question.
Normally, those URLs are relative to the Webstore and are used for Analytics tracking and this stat page (only available to you). See this mention, for example.
/track_install/... is, quite obviously, used as a beacon to track installs.
/webstore/detail/ext/free/... tracks opening your extension's listing in Web Store.
Here's documentation on homepage_url, which I believe influenced this, including this quote:
If you distribute your extension using the Chrome Web Store, the homepage URL defaults to the extension's own page.
I believe that it's either a bug that those are sent out to your server instead, or a feature I haven't seen documented anywhere to let you track those instead. Note that those are just beacons sent from analytics code; you don't need to serve content on them.
In any case, it's worth reporting, either on the bugtracker or via the exceptionally well-hidden developer support form.
