Google AI Overviews are AI generated summaries that appear at the top of many Google search results pages. They synthesise information from a small number of sources, name those sources, and often answer the user's question completely so they never need to click through.
For UK businesses, AI Overviews now appear on a growing share of search results, particularly for informational queries, how to questions, comparisons, and definitional searches. They often push the first organic result well below the fold.
