An article can be perfectly structured and still lose citations because it's incomplete — missing the subtopics an authoritative answer would include. This tool compares your article against a target query and maps the gap: what you cover, what you're missing, and an honest verdict.
Why it matters for AI search: when an AI assistant synthesizes an answer, it effectively builds a mental checklist of what a complete response includes, then pulls from sources that cover those pieces. An article on "how to block AI crawlers" that never mentions Google-Extended, or a CRM comparison that skips pricing, forces the assistant to supplement from other sources — diluting your citation or replacing it entirely. Topical completeness is the content-side counterpart to structural quality: structure determines whether your content can be extracted; coverage determines whether it's worth extracting.
How this tool works: enter the query you want the article to win (phrased the way a user would ask it) and paste your article text. The AI returns three sections: Covered — the entities and subtopics your article handles, each with a word of evidence; Missing — the entities an authoritative answer to your target query would include but your article doesn't, filtered for genuine relevance rather than padded lists; and a one-sentence Verdict on overall coverage. Use the Missing list as an edit plan: each item is a candidate section, paragraph, or table for your next revision. Free usage is capped at 3 checks per day.
Limitations: the gap list reflects a language model's judgment of what an authoritative answer includes — usually sensible, occasionally generic, and worth filtering against your own audience knowledge rather than following mechanically. Input is truncated to roughly 6,000 characters, so for long articles paste the core sections. The tool evaluates one article against one query; it doesn't crawl competitors or measure your site-wide topical authority. Pair it with the GEO Content Structure Analyzer — coverage plus structure is the full content-side picture, with the AI-Readiness Audit covering the technical side.
