UTM Builder
Build one campaign URL or a hundred. Enforce naming hygiene, use channel presets, save local templates, expand variant matrices, and export bulk CSV — all in your browser, no signup.
Extra key=value pairs (Adobe CID, internal tags, etc.). Not the five standard UTM keys.
Applied to UTM values in the live URL and bulk export. Fields normalize on blur when hygiene is on.
Variant matrix
Enter multiple values for source, medium, and/or content (comma or newline separated). Expands into every combination against the base URL with fixed campaign and term from the form above. Hygiene and custom parameters apply.
Bulk CSV / multi-URL builder
Paste one URL per line, or CSV with columns url, source, medium, campaign, term, content. Blank cells inherit values from the form above. Hygiene rules apply.
