Frequently asked

What are Google AI Overviews?
AI Overviews (AIO) is Google's AI-generated answer surface that appears above the traditional Search results list for many queries, summarising answers and citing sources.
How does AIO choose sources?
AIO draws on Google's Search index plus the Knowledge Graph and Featured Snippets. Pages with valid FAQPage schema, strong E-E-A-T signals, and KG presence are more likely to be cited.
Can publishers opt out of AIO?
Google offers crawl-level controls (Google-Extended) but no granular opt-out of AIO specifically. Most publishers benefit from inclusion via stronger citation patterns.
