# First-touch attribution

> A model that gives all the credit for a conversion to the first known touch.

Also called: first-click attribution.

First touch answers "what introduced this buyer?". All the credit goes to the earliest touch the tool recorded: the first ad click, search, post or link.

It is the right lens for channels that create demand: prospecting ads, content, podcasts, partnerships. Its weakness is memory. A tool can only see as far back as its data reaches, and browser limits such as Safari's 7-day cap on script-set cookies shorten that. A buyer's "first touch" may really be their second or third.

Compare it with last touch before cutting a channel. See [attribution models explained](https://datacenter.so/guides/attribution-models-explained).
