Google’s search engine has been given an AI overhaul. The web giant has activated a new feature Australia-wide that will deliver answers from its generative chatbot Gemini that will sit above the usual list of web results.

The feature, called AI Overviews, has been live for months in the US and elsewhere. While some users have been impressed by its ability to summarise information from multiple sources, others have expressed concerns over accuracy, potential manipulation and the interruption to advertising revenue for sites, which will be visited less often since the information is available directly on Google.

Google says the feature is designed to appear when users are making searches that would usually have them clicking through multiple links or scrolling through results. The AI-powered summaries won’t appear if regular search results are clear enough, or if they are for certain sensitive topics.

The tech giant also said it was continuing to improve the AI feature, including making links to the websites it gets information from more prominent. It says AI Overviews create more opportunities for web content to be discovered, and it said users spent more time at the websites they were referred to through the feature compared to regular Google Search.

“The idea is to create a jumping-off point to create a way to bring key information about a topic or a question at the top of your search results with links to go deeper, so you can quickly get to the content that makes the most sense for you,” said Hema Budaraju, Google’s senior director of product management for Search.

“As we evolve the search experience with AI, we continue to stay focused on connecting people to content from a diverse range of sources. We have tappable site icons that help people get to the various citations in AI overviews, and our pre-launch testing has found this is increasing traffic to supporting websites.”

At least 90 per cent of web searches in Australia go through Google, so it may be taking a calculated risk in changing its flagship product to compete with the likes of Microsoft’s Bing and ChatGPT. However, it has clearly seen a big jump in users moving to generative AI services where they would previously have Googled, especially in the under-24 age bracket.

AI Overviews is an attempt to have it both ways. Google wants to make it clear that everything that made it the preferred search engine is still there, but that it also has quick chatbot answers.
