Another failed attempt to kill SEO
If Marie Haynes, Barry Schwartz or Cindy Krum had written an article declaring SEO dead and proposing we rebrand our industry you’d seriously consider it. Wouldn’t you? What about Zach Cohen and Seema Amble? I don’t know either. Looked them up just now. Two VC people with insignificant footprint or long-term interest in SEO, Machine…

Dissecting Gemini’s Tokenizer and Token Scores
As a technical SEO, you might be diving into machine learning (ML) to understand how tools like Google’s Gemini process text. One foundational concept is subword tokenization—breaking words into smaller pieces called “tokens.” While tokens themselves are context-agnostic (they don’t consider surrounding words), they do carry an inherent bias: each token’s likelihood reflects how prominent…

Query Fan-Out Prompt Implementation in Google’s Open-Source Agentic Framework
Google’s open-source “Gemini Fullstack LangGraph Quickstart” pairs Gemini 2.5 with LangGraph to showcase a fully transparent, citation-driven research agent (Mikami 2025). A React frontend (Vite, Tailwind CSS, Shadcn UI) collects user queries and displays progress, while a FastAPI/LangGraph backend orchestrates a multi-step workflow: Although this isn’t Google’s official Gemini implementation as seen in AI Mode…

From Hallucinations to Clicks
Anastasia Kotsiubynska proposed a method to repurpose LLM-hallucinated URLs and set up redirects from hallucinated 404 instances with more than one session to most similar valid 200 pages. I really like this, but since I work on websites with many millions of pages where volumes of hallucinated URLs are typically beyond the scope of manual…

AI Mode & Page Indexing
Our tests show that Google’s AI Mode doesn’t retrieve page content from the live web but somewhere else, and that “somewhere else” appears to be a proprietary content store separate from the search index. How do we know this? We found a case where AI Mode failed to fetch a page that’s indexed and ranking…

AI Mode is Not Live Web
I recently stumbled upon a fascinating aspect of how Google’s AI Mode (powered by a custom Gemini model) interacts with the internet. I ran a simple test, and the results suggest that instead of performing truly live fetches for all URLs, the AI Mode relies on Google’s existing index or a cached version of the…
