Using Parameters and SubID to Track Links

SubIDs are query parameters that marketers add to their links to track specific traffic sources, campaigns, or placements. They're commonly used in affiliate marketing to identify which of your ads or content generated a click or conversion.

Most affiliate networks support subIDs, but there is no set standard for the parameter name—common variations include subid, sub_id, s1, and click_id.

A query parameter, sometimes called a query string, is a set of values added to the end of a 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

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

For example, if your link is:

https://linkly.link/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 a URL, and even string multiple ones together, for example:

https://linkly.link/4a?subid=facebook&campaign=retarget

which will record subid=facebook and campaign=retarget.

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

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

The following parameters are stripped. We do not record this data in the parameters tab or in our database.
