Using Parameters and SubID to Track Links

What is a SubID?

SubIDs are query parameters provided by traffic sources that allow you determine exactly which ad was clicked on.

Most affiliate networks provide some version of subID, but there is no set standard.

What is an URL parameter?

A query parameter, sometimes called a query string, is a set of values added to the end of an URL that specify something about the traffic source.

For example, you might have:

https://your-url.com/page?source=facebook

In this case, source=facebook is the query string.

You can add as many of these as you like, using ‘&’ to separate values.

https://your-url.com/page?source=facebook&medium=cpc

How to use a subID

Linkly records the query parameters used when a user clicks a link.

For example, if your link is:

https://linklyhq.com/l/4a?subid=facebook

Linkly will record subid=facebook for that click, and show it in the reports.

You can append any key=value pair onto an URL, and even string multiple ones together, for example:

https://linklyhq.com/l/4a?subid=facebook&campaign=retarget

which will record subid=facebook and campaign=retarget.

Results are shown in the traffic reports under the ‘Parameters’ tab.

See traffic for a single SubID/parameter

In your link’s traffic report, under the ‘Parameters’ tab, click 'Filter’ to show just traffic for this parameter value.
