According to LinkedIn's official documentation, the li_fat_id cookie's validity is 30 days from the user's last click or the latest click. After 30 days, the cookie expires, but it can be stored and sent back to LinkedIn Ads again.

Li_fat_id serves multiple purposes, including robust conversion tracking, improved retargeting performance, and enhanced analytics. It allows LinkedIn to identify users consistently, benefiting marketers in various ways.

Unlike other GCLID and fbclid that change with each click, li_fat_id remains constant for a user, providing lifetime tracking. Li_fat_id also offers better tracking accuracy and consistency compared to GCLID and fbclid.
