Tracking external sources

If you link to your add-on's details page or directly to its file from an external site, such as your blog or website, you can append a parameter to be tracked as an additional download source on this page. For example, the following links would appear as sourced by your blog:

Add-on Details Page

https://addons.mozilla.org/addon/cardbook?src=external-blog

Direct File Link

https://addons.mozilla.org/downloads/latest/634298/addon-634298-latest.xpi?src=external-blog

Only src parameters that begin with "external-" will be tracked, up to 61 additional characters. Any text after "external-" can be used to describe the source, such as "external-blog", "external-sidebar", "external-campaign225", etc. The following URL-safe characters are allowed: a-z A-Z - . _ ~ % +
