The term SGE is Search Generative Experience. This is a new Google feature launched in May 2023 in the US and in September 2023 in India and Japan as well.
This feature will allow users to search in natural language and receive answers from Google in a natural way in the form of content paragraphs combined with links to websites or links to products – depending on the search performed.
The feature works on a language model called PaLM 2 – an artificial neural network that resembles/imitates the human nervous system. The language model is based on a huge amount of content, products, data and media – something that allows it to understand in a more natural and clear way the search the user made and to give the user a full, natural and more correct answer for the specific search.
This feature, according to Google, will be integrated at the top of the search results page, above paid ads.
