Result
This page opens the UTM builder with the social convention prefilled: utm_source=facebook and utm_medium=social. Fill in the campaign name and copy the finished link.
The usual refinement on this channel is splitting paid from organic: many teams keep utm_medium=social for organic posts and switch to paid-social (or cpc) for boosted and dark posts, so the two never blur together in reports. utm_content is the workhorse here — use it to tell apart the image ad, the carousel and the story placement running under the same campaign name.
Values with spaces or capital letters are the classic way Facebook campaign reports fall apart, so leave both cleanup toggles on. The link is assembled locally in your browser, existing parameters on your landing page URL are preserved, and nothing is uploaded anywhere.
