1 canonical article. Overwijk is co-inventor with Li Xiong, Chuan Hu, and Junaid Ahmed on the Site Topical Authority patent (US 20210004416, the formula A(s,t) = SR(s) * C(s) * T(s,t)^2 that explicitly quantifies per-site per-topic authority by combining global site rank, click signal, and squared per-topic page share). The most precise mathematical formulation of topical authority in the modern patent literature. Conceptually paired with Procopio (per-author per-topic authority) and Agent Rank (author-level reputation, 65gp pat-47).

Each inventor track inside the Nizam SEO War Room patents archive isolates one engineer's research arc — typically a decade or more of continuations, divisionals, and follow-up patents on a coherent research thread. Reading by inventor (rather than by topic) recovers the narrative: how the original disclosure evolved, what the continuations added, which claims got carved out into divisional applications, and how the thread eventually intersected with other research lines at Google or Microsoft. This is how working SEOs build durable intuition about search-engine internals — not by memorizing claim language, but by following the research bibliography that shipped the algorithms we now optimize against.
How to read this track
Start with the earliest filing — it sets the foundational disclosure. Continuations refine the claims; divisional applications split out separable inventions; the follow-up patents tend to introduce performance optimizations, edge-case handling, or downstream integration with other systems. Each patent on this site is annotated with the ranking surface it touches — query understanding, document retrieval, ranking, behavioral signals, knowledge graph, or AI search — so the practitioner can map the research back to the algorithm output observed on live SERPs.
For example, a working SEO consultant uses Arnold Overwijk, Microsoft Site Topical Authority when diagnosing a ranking drop, planning a content calendar, or briefing a client on why a tactic shifted. However, the concept only compounds when paired with the surrounding entries in the encyclopedia and patents archive. In addition, the platform connects this concept to live SERP data so the theory carries through to execution.
