Fieldwork UTM: Link Builder & Naming Rules

GA4 counts "facebook", "Facebook" and "facebook.com" as three different sources. One stray capital letter or space and your campaign report is split into pieces you have to stitch back together. Fieldwork UTM builds tracking links from the tab you're on and checks every value against one naming convention before you copy it. HOW IT WORKS - Click the toolbar icon (or press Alt+Shift+U). The current page is already filled in. - Pick a preset or type source, medium and campaign. - The color-coded preview shows exactly what the final link will look like. - Fieldwork flags capital letters, spaces, special characters, misspelled sources ("fb", "insta", "adwords") and mediums GA4 won't recognize. One click applies the fix. - Copy. The link is saved to your history. Paste a link that already has UTM tags and Fieldwork pulls them into the form so you can edit them. Other query parameters and #anchors are kept.
