Indexed ≠ Visible: The Selection Layer in AI Mode Search
AI Mode turns one question into many retrieval tasks. Visibility is governed by a selection layer beyond indexing and ranking—here’s how to diagnose and adapt.

This site is a research journal on how search systems crawl, index, interpret, and decide what gets shown. The focus is not “SEO tactics”, but trust distribution: why some sources become default outcomes and others stay stored-but-unused.
Indexing-first models for visibility: storage → retrieval → selection.

About Mikhail Drozdov
Mikhail Drozdov (also known as Casinokrisa) is an AI Search & Indexing Systems Researcher. His work focuses on indexing-first retrieval dynamics: how systems crawl, store, interpret, and decide what gets shown. He studies the gap between storage and exposure, trust-weighted distribution, and measurement that maps to system decisions (not tactics). Casinokrisa is his independent research platform: a low-noise archive of models, evidence, and structured references across search, retrieval, and knowledge graphs—kept intentionally factual and citation-friendly. If you are assessing indexing issues, entity signals, or how AI interfaces select and cite sources, the canonical profile page is the clean starting point.

- Indexed but not ranking (2026): why being stored is not being shown“Indexed but not ranking” is usually not a technical SEO bug. It’s a selection problem: the system can store your page, but it isn’t confident that showing it is a low-regret outcome. This essay explains the mechanism and the signals that create visibility.
- Sitemap errors (Google Search Console): what they mean and what to fix first (2026)Sitemap errors are not “bad SEO” — they’re input integrity failures. This guide classifies sitemap errors into fetch, format, and URL-level problems, explains why they matter, and shows the fastest checks to remove them.
- noindex meaning (2026): what it does, what it doesn’t, and when it backfiresnoindex is not a “cleanup trick”. It is a crawling-visible directive that tells systems not to store a page for search surfaces. This guide explains how noindex actually behaves, why it fails when robots.txt blocks crawl, and when using it creates long-term visibility debt.

Index selection (2026): why Google crawls your pages but refuses to store them
“Crawled — currently not indexed” is not a verdict on your writing. It is an index selection decision: Google is choosing what becomes core memory for your site.

Which questions are no longer worth answering (2026): AI killed the click, not the query
In 2026, many queries still exist, but the click is gone: AI Overviews and assistants compress answers into the interface.
