How to tag Facebook links
Posts, comments and ads
Links are clickable in Page posts, in comments and in ads. Tag the link in the post; if a Page's link posts are limited, put the tagged link in the first comment.
Facebook's link shim is fine
Facebook opens outside links through l.facebook.com, a safety check that hides which page the click came from. Your UTM tags are what tell GA4 the visit came from Facebook.
Organic and paid apart
Use utm_medium=social for Page posts and a paid medium such as paid-social for ads. facebook is on GA4's social list, so they land in Organic and Paid Social.
Example: A Page post linking to a spring offer = https://example.com/spring?utm_source=facebook&utm_medium=social&utm_campaign=spring-sale

Where links work on Facebook, and how to tag them
Every place a link can sit on Facebook, whether people can click it, and the tag to give it.
| Where the link sits | Clickable? | Tag to add |
|---|---|---|
| Page posts | Clickable | utm_medium=social |
| Comments, including the first comment | Clickable | utm_content=first-comment |
| Reels captions | Clickable | utm_content=reel |
| Page buttons and About | Clickable | utm_content=page-button |
| Ads | Clickable | utm_medium=paid-social |
In December 2025 Meta began testing a cap of about 2 link posts a month for Pages without Meta Verified; links in comments were not affected. If your Page is in the test, the first comment is the place for the tagged link.
