Investigative essays for a web where the answer is the destination, not the link. Researched, sourced, and argued.
These are the long arguments. For dated reporting on what changed this week, read the SEO and GEO news.
These pieces assume the vocabulary rather than re-explaining it each time. If a term is doing unfamiliar work, it is defined in the glossary.
The August 2026 spam update ran 2 days 16 hours and introduced no new policy. Three changes in the same fortnight never entered the ranking log, and two of them came from regulators rather than from Google.
Reddit's share of ChatGPT Search citations fell 86.4% in under two weeks after an August 2026 robots.txt block. There was no penalty — the retrieval layer simply routed around a door that closed.
Published 2026 retention figures for Perplexity range from 44% to 89% depending on who measured. The spread is not a detail — it is the finding, and it changes what an AI visibility report is worth.
ChatGPT recommends 1.2% of local business locations. Gemini recommends 11%. Google's local 3-pack shows the same brands 35.9% of the time. The gap is a data problem, not a content problem.
Nobody sees an Instagram ad at 9pm and books a $60,000 basement by 9:05. Most renovation companies run their Meta ads as if they do — one campaign, one “Get a Free Quote” button, and a cost per lead that keeps climbing.
Query fan-out is documented, defined, and demoed in Google's own developer docs. What happens after fan-out retrieves candidate pages has never been disclosed — and two "Google AI Overview patents" widely cited in SEO content belong to Glean and Microsoft.
Copilot Mode: retired. Project Mariner: shut down. ChatGPT Atlas: sunsetting. Three of the industry's flagship agentic browsers stopped existing as standalone products in one quarter — not because the technology failed, but because it won.
Google's ad revenue is up 17% year over year even as CPCs climb double digits and its own share of the search-ad market slips below 50% for the first time in two decades.
Four independently-run studies contradict Google's "clicks are stable" line on AI Overviews — and Google's own anti-chunking advice quietly conflicts with the citation mechanics its search engineers describe.
Google Search Central tells publishers not to fragment pages for AI — but Passage Ranking, Anthropic's Contextual Retrieval, and Ahrefs' citation data all show retrieval happening below the page level.
The most-cited AI-citation study ran on GPT-3.5 and five fake search results. Ahrefs, Otterly, and Chroma's actual production data point somewhere else entirely.
Two years of Ahrefs, Semrush, and Pew data show featured snippets collapsing 60-90%+ as AI Overviews expanded — and in January 2026, Google's own VP of Engineering confirmed why: snippets never left, they just moved backstage.
Microsoft Copilot passed 20 million paid seats and Glean is valued at $7.2B, but a controlled study shows JSON-LD schema barely moves RAG accuracy. Legible prose does.
The technical blueprint SEO content keeps calling "Google's entity resolution patent" — including GraphRAG — belongs to Microsoft and IBM. Here's what Google has actually filed, and what it hasn't.
Chegg, Business Insider and WPP cut thousands of roles citing AI and Google traffic. Meanwhile SEO job postings with "AI" in the title pay 27% more. Here's what the data actually supports — and what doesn't hold up.
Five independent studies quietly agree: off-site brand mentions, not backlinks, now drive AI visibility. Here's the gap between the data and what Google keeps saying.
Google made manipulating AI answers a spam violation. Weeks later, research showed a 13-word edit poisons AI agents up to 62% of the time — and every defense failed.
Per-query clicks have collapsed — but a Google patent points somewhere worse: a web where the destination page is never visited because Google generates it.
