Study finds Google AI mode returns largely different results across sessions
A new study found that Google's AI mode (Search Generative Experience) frequently provides inconsistent results for the same queries. Testing across sessions revealed that up to 91% of URLs differed for identical queries, showing the dynamic nature of the AI response engine.
This inconsistency may affect how users and marketers perceive reliability and visibility in AI-generated search results, suggesting a need for different SEO approaches tailored to AI variability.
Google’s John Mueller says core updates build on long-term data
In a recent discussion, Google’s John Mueller clarified that core updates are not triggered by recent links or sudden ranking changes. Instead, they’re built on long-term patterns in site quality, relevance, and user satisfaction signals.
Mueller also reiterated that disavowing links is largely unnecessary for modern SEO unless there are historic, manual action cases. Google continues to emphasize overall content quality over technical manipulations.
Google says many top sites have invalid HTML yet still rank
Google confirmed that many top-ranking websites contain invalid HTML markup, yet still appear prominently in search results. The key factor is whether the content is still accessible and interpretable by Google's systems.
This statement reassures webmasters that while clean code is beneficial, perfect validation is not essential for ranking, Google prioritizes content value and crawlability over technical perfection.
Google’s trust ranking patent shows user behavior influences rankings
A newly revealed Google patent outlines a system that evaluates website trust based on user behavior signals like visit frequency and engagement. This suggests Google may factor behavioral trust indicators into rankings alongside content and links.
The patent describes how these trust scores are computed and updated, offering insight into how search algorithms might weigh user interaction as part of the ranking process.
Google rolls out June 2025 core update with three-week rollout window
Google announced the launch of its June 2025 core update, which began rolling out on June 30 and is expected to complete within three weeks. As with previous updates, changes aim to improve the relevance and quality of search results.
No immediate specifics on affected industries were given. Google encouraged site owners to review its guidance on core updates if they see ranking fluctuations.
Google integrates Search Console Insights into main platform
Google has merged Search Console Insights into the main Search Console interface. Previously accessible through a separate page, Insights now lives within the performance reports section.
This move aims to improve accessibility for webmasters seeking traffic trends, top-performing content, and audience behavior data, all from a unified dashboard.
Google tests token auction ad system using AI to write ads in real time
Google is experimenting with a “token auction” system in which large language models generate ad text in real time. Instead of bidding on keywords, advertisers bid on individual tokens that compose dynamic AI-generated ads.
The approach allows for ultra-personalized ads tailored on the fly to user queries. This system is still in testing and has not yet been rolled out publicly.
Google to ban ads for pill presses and related equipment
Starting September 1, 2025, Google will prohibit advertisements for pill presses and related machinery. This includes encapsulating machines and parts used in pill production.
The update is intended to curb misuse of such equipment in the production of illegal substances and align with global safety and legal standards in advertising.
