Gemini stops tagging cited links with utm_source=gemini

A UTM tag is a short label on the end of a web address that tells analytics tools, Google Analytics among them, where a visitor came from. Desktop visits are still covered by the referrer, the note a browser sends saying which page a click came from: those visits carry gemini.google.com, and in Turrado’s logs their number held steady the whole time. Clicks that arrive without any referrer, which PPC Land says includes many from the Gemini phone apps, now fall into the direct-traffic bucket with nothing to tie them to Gemini. Google has given no reason for dropping the tag and no word on whether it returns.

Gemini’s Free plan includes Deep Research, the feature that writes a sourced report from many web pages, and paid Google AI plans start at $4.99 a month (AI Plus), with AI Pro at $19.99, on our 1 November check.

A site that began counting Gemini visits from the tag in September sees that line fall from about 28 September even where real visits held steady, so the referrer count is the one figure that stays comparable across the whole month.
