An SEO crafting a newsletter with AI spotted a hallucination about a March 2026 Google Core Update and decided to publish it as an experiment to see how misinformation spreads. While search marketing industry publications ignored the fake news some independent SEOs picked it up and ran with it without first checking the factual accuracy of the news.<\/p>
Mistake Leads To A Double Take<\/h2>
The person who did the experiment, Jon Goodey (LinkedIn profile), published a LinkedIn article that purposely contained an AI hallucination about a non-existent March 2026 Google Core update. He explained, in a subsequent Linkedin post, that his AI workflow contains human quality control to catch AI mistakes and when he spotted it he decided to go ahead and publish it to see if anyone would dispute or challenge the false information.<\/p>
Google Ranks Misinformation<\/h2>
Goodey explained that it was Google itself that fueled the misinformation about the fake core algorithm update as his LinkedIn newsletter ranked for the phrase Google March Update 2026. The fake news ranked in Google\u2019s classic search and in AI Overviews.<\/p>
He explained:<\/em><\/p> \u201cMy LinkedIn article began ranking on the first page of Google for \u201cGoogle March update 2026.\u201d Not buried on page three. Right there, visible to anyone searching for information about recent Google algorithm changes.<\/p> \u2026Google\u2019s own AI Overview feature picked up the fabricated information and presented it as fact.\u201d<\/p> <\/blockquote> Google\u2019s fact checking in the search results is basically non-existent, so it\u2019s not surprising that Google\u2019s search engine would rank the fake information, especially for anything related to SEO. Using Google for SEO queries is like playing a slot machine, you have no idea if the information will be right or a total fabrication.<\/p> Searching for information about a dubious black hat tactic (like Google stacking) may cause Google to actually validate it, potentially misleading an honest business person who wouldn\u2019t know better.<\/p> This is a longstanding black spot on Google\u2019s search results and is why it\u2019s not surprising to see Google spew out misinformation about a fake Google update.<\/p> The result is that SEO websites began repeating the false update information because of course, Google core updates are a traffic magnet and a way some SEOs attract potential clients. There\u2019s a long history in the SEO community of stirring up noise about non-existent updates, so again, not surprising to see SEO agencies pick up this ball and run with it.<\/p> Goodey shared:<\/em><\/p> \u201cMultiple websites published detailed, authoritative-sounding articles about the \u201cMarch 2026 Core Update,\u201d treating it as confirmed fact. These weren\u2019t throwaway blog posts. They were detailed pieces with specific claims about Gemini 4.0 Semantic Filters, Information Gain metrics, and recovery strategies.\u201d<\/p> <\/blockquote> SEJ and our competitors ignored the fake March update news. But a technology site apparently did not, with Goodey calling them out about it.<\/p> He wrote:<\/em><\/p> \u201cAnother site, TechBytes, went even further with a piece by Dillip Chowdary headlined \u201cGoogle March 2026 Core Update: Cracking Down on \u2018Agentic Slop\u2019.\u201d (Oh, the irony\u2026).<\/p> This article invented specific technical details including claims about a \u201cGemini 4.0 Semantic Filter,\u201d a \u201cZero Information Gain\u201d classification system, and a \u201cDiscover 2.0 Engine\u201d prioritising long-form technical narratives.\u201d<\/p> <\/blockquote> I recall Google\u2019s Danny Sullivan talking about how Google doesn\u2019t do fact checking but I couldn\u2019t find his tweet or statement. There is however a news report published in Axios related to fact checking where a Google spokesperson affirms that Google will not abide by an EU law that requires fact checking.<\/p> According to the news article:<\/em><\/p> \u201cIn a letter written to Renate Nikolay, the deputy director general under the content and technology arm at the European Commission, Google\u2019s global affairs president Kent Walker said the fact-checking integration required by the Commission\u2019s new Disinformation Code of Practice \u201csimply isn\u2019t appropriate or effective for our services\u201d and said Google won\u2019t commit to it.<\/p> The code would require Google to incorporate fact-check results alongside Google\u2019s search results and YouTube videos. It would also force Google to build fact-checking into its ranking systems and algorithms.<\/p> Walker said Google\u2019s current approach to content moderation works and pointed to successful content moderation during last year\u2019s \u201cunprecedented cycle of global elections\u201d as proof. Jon Goodey had multiple takeaways, with the most important one being that people should fact check what they read online.<\/p> Other takeaways are:<\/strong><\/p> Featured Image by Shutterstock\/Rawpixel.com<\/em><\/p> <\/div> News,SEO#SEO #Test #Shows #Trivial #Rank #Misinformation #Google #sejournal #martinibuster1774056699<\/p> ","protected":false},"excerpt":{"rendered":" An SEO crafting a newsletter with AI spotted a hallucination about a March 2026 Google Core Update and decided to publish it as an experiment to see how misinformation spreads.
