AI Overview

Also known as: AI overviews, generative search

AI Overview is a feature where AI displays summary answers at the top of Google search results. It sparked a zero-click debate that led to a decline in website visits.

AI Overview is a function that shows AI answers that summarize the contents of multiple web pages at the top of Google search results. In the past, you had to go through a list of blue links to find the answer yourself, but now the librarian summarizes the contents of the book first.

As conversational AI like ChatGPT encroached on search demand, Google came up with a response by combining generative AI with search. Users get answers quickly without clicking, but this leads to the so-called zero-click problem, which reduces visits to the original website.

From the perspective of media companies and websites that create content, there is a lot of backlash because it reduces traffic and advertising revenue. In addition, as cases where AI summaries showed incorrect information as fact became known, controversy over its reliability continued.
