UTM for paid vs organic social
Paid social ads and organic social posts can drive clicks from the same platform, but they are different channels with different costs and goals. The reliable way to separate them is a deliberate utm_medium convention, since the platform domain alone cannot distinguish a boosted ad from an organic share. This page sets out a clean split.
Why the platform alone is not enough
A click from a Meta ad and a click from an organic Facebook post can share the same referrer and source token, so utm_source alone cannot tell them apart. The distinction has to live in utm_medium.
A common convention is utm_medium=paid_social (or cpc) for ads and utm_medium=social (or organic_social) for unpaid posts, keeping utm_source as the platform name in both cases.
- utm_source = platform (e.g. facebook, linkedin)
- utm_medium=paid_social or cpc for ads
- utm_medium=social or organic_social for posts
Aligning with channel grouping
Analytics default channel groupings classify many sources into Paid Social vs Organic Social based on the medium value, so picking medium tokens the tool recognizes makes your reports line up with built-in channels.
Document the chosen vocabulary in your taxonomy and apply it consistently so the same medium is never spelled two ways. Validate that ad platform auto-tagging or link builders are not overriding your medium with their own.
How it appears in analytics and logs
Two rows for the same platform — one paid_social, one organic/social — confirm your medium convention is separating ad clicks from post clicks; a single blended row means the medium was not differentiated.
Diagnostic use case
Report paid social and organic social as separate channels by assigning distinct utm_medium values, so ad spend performance is not blended with unpaid reach.
What WebmasterID can help detect
WebmasterID records each tagged social landing hit by its medium, so paid and organic social on the same platform stay separable as distinct campaign sources.
Common mistakes
- Using the same medium for ads and posts, blending paid and organic.
- Choosing medium tokens the channel grouping does not recognize.
- Letting an ad tool overwrite your medium so organic and paid mix.
Privacy and accuracy notes
The medium and source values describe the channel and campaign, not the person. Geography stays a coarse edge estimate, and WebmasterID records the touch without raw IP, exact location, or a cross-site identity.

Meta Ads (Facebook and Instagram paid placements) lets you attach UTM parameters at the ad level through the URL Parameters field or the destination URL.

- Facebook campaign tracking with UTM
Facebook commonly opens links inside its in-app browser, which frequently strips the web referrer, so untagged Facebook clicks land in direct. This page gives a recommended utm_source=facebook structure for organic posts and Facebook Ads, and the rule that no audience data belongs in a public URL.

Analytics tools sort traffic into channel groups (Paid Search, Organic Social, Email, Referral, Other) using rules built mostly on utm_medium. Choose the wrong medium and good traffic falls into 'Other' or the wrong channel. This page explains how the mapping works and the medium values that keep channels correct.
