The Shifting landscape of Search: Are AI Overviews Rewriting Citations and Rankings?
The introduction of Google’s AI Overviews (AIOs) has sparked debate about its impact on traditional search results. Are these AI-powered summaries changing where information comes from, and even what information gets cited? Recent research suggests the answer is complex, and the implications are meaningful for content creators and SEO professionals.
Initial Concerns & Google’s Response
When the Pew Research Center initially published findings on AIOs, Google disputed the results.However, subsequent studies have echoed similar trends, raising valid concerns about the shift in how information is presented and sourced.
For example, Ahrefs, a leading search analysis tool, found a 34.5% decrease in click-through rates to the top organic result when an AIO appeared above it. This suggests users are increasingly satisfied with the AI-generated summary, reducing the need to click through to individual websites.
Diving Deeper: Originality.ai‘s Findings
Originality.ai, a platform focused on AI content detection, conducted its own investigation into AIO citations. Their findings paint a nuanced picture:
Human-Written Content Still Dominates: 74.4% of citations within AIOs where originally written by humans. A Significant Portion Remains Unclassifiable: 15.2% of citations were categorized as “unclassifiable” due to factors like:
Short length
Video format
PDF format
Broken links (20% of unclassifiable citations)
Beyond the Top 100: A surprising 52% of working links cited by AIOs didn’t rank within Google’s top 100 organic results for the same search term. of those, 12.8% were flagged as AI-generated – a higher rate than the overall 10.4% across all citations.
This suggests AIOs are pulling information from sources Google’s traditional algorithm might not prioritize.
Conflicting data: ahrefs vs. Originality.ai
Interestingly, originality.ai’s results contrast with a larger study by Ahrefs. Their July analysis of 1.9 million citations from 1 million aios revealed:
76% of cited pages ranked in the top 10.
9.5% ranked within the top 100.
Only 14.4% didn’t rank at all.
what explains this discrepancy?
The YMYL Factor & Google’s “Query Fan Out”
Experts believe the difference lies in the type of queries analyzed. Sam robson,CEO of The Better Web Co. (an SEO firm),suggests Originality.ai’s focus on “Your Money or Your Life” (YMYL) topics – those impacting health, finances, and safety – is key.
“AI Overviews are powered by Gemini, and being Google’s own LLM, it’s designed to parse deeper and more varied training materials than Googlebot / Google Search ever have been,” Robson explains. “This might mean that,in the YMYL space,where great information is contained in PDFs,whitepapers,and othre formats not optimized for traditional search,AI overviews is doing a better job of highlighting these more varied resources.”
Google also clarifies that AIOs don’t simply cite pages ranking for your exact query. They utilize a “query fan out technique” - conducting numerous related searches to build a complete response. this means the AI may be drawing from sources relevant to similar queries, even if they don’t rank for your initial search.
What Dose This Mean for You?
The rise of AIOs is reshaping the search landscape. Here’s what you need to consider:
Traditional Ranking Isn’t Everything: Getting into the top 10 is still valuable, but AIOs demonstrate that valuable content can be discovered and cited even outside those top rankings. Diversify Your Content formats: Don’t limit yourself to blog posts. Consider creating PDFs,
