Content Moats (Topical Authority)
also: topical authority · compounding content · SEO moat
Definition
A content moat is a defensive advantage built from a deep, interconnected portfolio of articles on a topic such that search engines treat the publisher as the topical authority. Returns compound: each new article benefits from the authority of the existing set, while competitors cannot catch up without a comparable investment.
Topical authority in Google's post-BERT algorithms rewards publishers that cover a topic exhaustively and interconnectedly. The unit economics favor depth over breadth: ten articles on one topic outperform ten articles on ten topics, because internal linking and entity co-occurrence signal expertise. Content moats compound over 18–36 months — the moat only becomes defensible after the archive passes a threshold that competitors cannot shortcut with budget alone.

The Compounding Advantage of Content Moats: Modeling SEO as a Capital Investment with Depreciation Curves
A single well-written article generates traffic for years. That makes content a capital asset, not an operating expense — and like any capital asset, it depreciates. The companies that model this correctly build content moats that compound. The rest produce content that decays.
