"LinkedIn" and "linkedin" are two different sources in GA4 — not one.
Build a UTM link with values auto-lowercased and hyphenated before they hit the URL, so casing never quietly splits your own data into duplicate rows. One link at a time, or a whole table of placements at once.
Single link — free
Source, medium and campaign are required. Term and content are optional.
Add a valid destination URL, source, medium and campaign.
Why everything gets lowercased
- GA4 does not merge UTM values that differ only by case —
utm_source=LinkedInandutm_source=linkedinbecome two separate rows, splitting one channel's traffic into two. - Spaces are converted to hyphens for the same reason: consistency across every link, without relying on everyone typing it the same way.
