What the setting changes
Google describes preferred sources as a way to personalize Top Stories, AI Mode and AI Overviews. Relevant, fresh content from chosen sources can appear more often in Top Stories, and preferred sources can be highlighted in AI features. This does not guarantee that a calculator or guide will appear for any particular search.
Some sources may be unavailable, including sites that are not updated regularly. If BACwater.ai is not listed, you can still bookmark a calculation tool or guide directly.
