Google Tells Sites to Fact-Check AI Content Before Publishing
Google has updated its guidance for websites using generative AI to explicitly require manual fact-checking of all AI-generated content before publication. This new directive addresses the risk of hallucinations by mandating human review of both article text and metadata elements like titles and alt text. The update aligns with previous statements from Google employees and reinforces the company's stance on maintaining content accuracy and trustworthiness.
