Links and Campaigns

A Lucia link is how you collect attribution data across every customer. To measure a campaign's ROI, you need the canonical source of each visitor — and their journey across devices and platforms.

Links are the lifeblood of the Lucia attribution system: they reveal the relationship between each marketing channel and the users it brings in, so you can measure the full journey from first click to last conversion.

That full journey works when the Lucia SDK is installed on the sites your links point to — it ties each session to a single persistent profile per customer, across devices and wallets.
