AutoTag

AutoTag is a Tracking Tag feature that automatically appends the Click ID to every outbound link, form submission, and checkout redirect on your site — before the visitor clicks — so the identifier travels with them to the destination.

How AutoTag works

AutoTag uses the right parameter name for each destination: atclid by default, or the network-specific parameter when the destination is a recognized affiliate network (sid for CJ, subid for Impact and many others). For links AutoTag can’t auto-detect, place the --CLICK-ID-- token as any parameter’s value and the Tag substitutes the real Click ID at page load. If a link already carries a SubID value, AutoTag merges rather than overwrites. It requires links published as regular HTML anchors (not JavaScript-generated).

AutoTag is one of the Tracking Tag’s three automation features, alongside AutoScan (crawls the page to find trackable links and forms) and AutoTrack (tracks form submissions and outbound clicks).

AutoTag vs Click ID

Click ID — AutoTag appends the Click ID; it is not the identifier.

Frequently asked questions

FAQ was last reviewed on 2026-06-23

Do I need to set up UTM templates or tag links manually with AutoTag?

No. AutoTag detects outbound links and forms and appends the Click ID automatically, using the network's required parameter name (for example sid for CJ, subid for Impact) or atclid by default. For links it can't auto-detect, place the --CLICK-ID-- token as a parameter value and the Tag substitutes the real Click ID at page load.

What does AutoTag do if a link already has a SubID value?

It merges rather than overwrites. AutoTag requires links published as regular HTML anchors; links generated dynamically by JavaScript may not be tagged.
