Google requires manual fact‑checking of AI content and adds UTM tags to Gemini links
The Oct. 1 update expands manual review to metadata and reveals that Gemini links now carry UTM tags for referral tracking.
By Felo News Desk · Published
Google announced on Oct. 1 that its guidance for AI‑generated content now mandates a manual fact‑check of all page elements, and that links from its Gemini service are being tagged with UTM parameters, according to Search Engine Journal.
What happened
The company added three sentences to the “Focus on accuracy, quality, and relevance” section of its guidance, clarifying that generative models predict likely word sequences rather than retrieve facts. The new text instructs publishers to manually fact‑check and review AI‑generated content for accuracy and trustworthiness before publishing, and extends that requirement to titles, meta descriptions, structured data, and image alt text. In a separate observation, a Reddit user reported seeing UTM parameters on Gemini links, and Google’s John Mueller confirmed he also sees them. Mueller said he would forward details about how the referrer is handled to the team, and noted that Google has not yet documented the tagging process, according to Roger Montti.
What the reports add
Search Engine Journal notes that the manual‑review requirement aligns the treatment of AI‑generated metadata with that of article drafts, aiming to prevent overlooked inaccuracies in search results. The outlet also explains that UTM‑tagged Gemini links give site owners a way to track Gemini‑driven traffic without relying on referrer data, allowing comparison of sessions with and without tags.
What was said
“It is critical to manually fact‑check and review all AI‑generated content for accuracy and trustworthiness before publishing,” the updated guidance states, Search Engine Journal reports.
John Mueller told the outlet that he sees UTM parameters on Gemini links and will forward details to the team, adding that Google has not yet documented the tagging process, according to Roger Montti.
How it came about
The changes follow a series of updates Google has made to its helpful‑content and AI‑overview policies, including a fake‑author warning added on Oct. 1 (see Google adds fake author warning to guidance) and expanded external links in AI Overviews earlier in September. The new fact‑check step and UTM tagging aim to improve transparency and measurement for publishers using Google’s AI tools.
