“You may have the best answer in your site’s pages, but if they aren’t found within the Google search index, they risk not being cited in an AI Overview — no matter how well-optimized they are otherwise.”
Content Quality & Relevance
The study introduced a new way to measure content relevance using cosine similarity analysis.
It found that websites cited in AI Overviews often closely match the AI-generated summaries, indicating that higher quality content is linked to better visibility in AI search results.
What This Means
The study suggests several strategic priorities for businesses:
Measure visual SERP metrics like pixel depth to quantify true organic visibility
Analyze semantic similarity between page content and AI Overview summaries
Prioritize earning, growing, and defending top 12 organic ranking positions
Maintain strong SEO fundamentals to support organic performance
Develop a broader AI search strategy encompassing new platforms like Bing, ChatGPT Search, and Meta AI
Methodology & Scope
The research, conducted from August 15 to September 1, analyzed:
36,000 commercial keywords
85,638 informational keywords
22 websites across e-commerce, publishing, and branded sectors
Both desktop and mobile search results
Looking Ahead
The study reveals changes in how users view search results and how businesses should manage their online visibility. AI Overviews pose challenges for organic search but also present opportunities for adaptable businesses.
Key points for search marketers include maintaining strong organic rankings, tracking visual SERP positioning, and creating content that meets user needs.
As search engines enhance their AI tools, it’s vital to maintain a strong foundation of technical SEO while expanding AI-focused strategies for greater visibility.
