UTM Link Builder
Analytics is only as good as your tagging, and inconsistent tagging is the most common reason a report can't answer a simple question. This enforces lowercase and offers the presets we use, so "Instagram" and "instagram" never split a report again.

Everything is forced to lowercase — that's what stops one campaign splitting into three rows in your reports.

Which parameters actually matter?+
Source, medium and campaign carry almost all the value. Term and content are for finer splits within a campaign — useful, but skip them rather than filling them inconsistently.
Is this tool really free? Do I need an account?+
Free, and no account. Everything runs in your browser — we never see your numbers unless you press save to create a shareable link.
