Google has announced the expansion of content advisory for searches where its AI (Artificial Intelligence) system does not have high confidence in the overall quality of the results available for search. Google Search Vice President Pandu Nayak said that this does not mean that there is no useful information available or that a particular result is of low quality. "These notices provide context about the full set of results on the page, and you can always see the results of your query, even if the advice is present," he said in a blog post. Nayak also said in a blog post that Google has invested deeply in both information quality and information literacy for Search and News, and today we have some new developments regarding this important task. Google has also introduced the latest AI model called Multitask Unified Model (MUM) to improve search result quality in'snippets' that are shown at the top of the page for search.
