LinkDecoder

Trace redirect chains, parse UTM parameters, detect ad macros, and compare mobile vs desktop redirect paths.

Set test values for unresolved ad macros (e.g. {GCLID}, __CLICKID__) before analyzing.

Trace redirect chains

Follow every hop — 301, 302, 307, 308 — for both desktop and mobile user agents simultaneously.

Compare mobile vs desktop

Detect when iOS or Android traffic gets routed to a different destination than desktop browsers.

Score link health

Get an A–F grade across redirect efficiency, SSL security, analytics integrity, and mobile compatibility.
