analyzing-content-gapslisted

Use when running a competitor SERP diff, asking why a competitor outranks you, building a content brief, or auditing what top-3 ranking pages cover that yours doesn't. Auto-triggers on "content gap analysis", "competitor SERP", "why does X outrank us", "what are competitors covering that we aren't", "content brief", "SERP analysis". Takes a target query + your URL, scrapes top-3 via Firecrawl, diffs entities/H2s/schema/depth/freshness/AIO presence, and ships `CONTENT_BRIEF.md` with gaps ranked by impact. Pairs with `optimizing-on-page` (fills the gaps) and `planning-topic-clusters` (when gaps span sub-topics).

# Analyzing Content Gaps ## Overview The top 3 pages already won the editorial battle for a query — Google watched users vote with dwell, scroll, and pogo-sticks for months and decided those pages best serve the intent. Your job isn't to imagine what the page should cover. It's to **diff what they cover that you don't**, then decide which gaps deserve a response. **Core principle:** SERP-proven coverage beats imagination. Entities and sub-questions present across all top-3 are table stakes — if they're missing on your page, fix those first. ## Why this matters in 2026 - **AI Overviews appear on 50–60% of US Google searches**, average 157 words, and cite 8–13 sources [3]. AIO citations skew toward pages with deep entity coverage on the specific sub-question — 92% of citations come from top-10 pages, but 2 in 3 come from pages a normal SERP search wouldn't surface [4]. - **Topic Gaps replaced keyword gaps as the unit of analysis** [1]. Modern search treats keywords as surface representations of underlying entities. - **Featured snippets and AIO citations correlate strongly** — the answer-first patterns that win snippets win citations [3]. - **Skyscraper 1.0 is dead.** "Make it longer" no longer works; the 2026 evolution is better entities, sharper examples, tighter intent — not word count [5]. ## When to use - A competitor consistently outranks you for a query you care about - You're refreshing a page and need to know what to add - You need a content brief before writing
