The tags that quietly split your reports in two.

Questions
What does the checker look for?
The mistakes that stay silent: the same source or campaign written several ways, links missing source, medium or campaign, a medium that repeats the source, and the same link pasted twice.
Why does spelling matter so much?
Most analytics tools group visits by the exact string. LinkedIn and linkedin become two sources, so one campaign shows up as two lines, each carrying half of its numbers, and nothing flags it.
What belongs in utm_medium?
The kind of channel: cpc, paid_social, social, email, referral. The source says where exactly, like linkedin or newsletter. Putting the source in both leaves you with no grouping at all.
Do my links leave my browser?
No. This one runs entirely in the page: nothing is sent anywhere, and nothing is stored.
