Semantic Gap Analysis

You're on page two for a keyword and need to know exactly what to add, not just "write more." This pulls your page and the top three ranking competitors, extracts entities and predicates from all of them, then builds a gap inventory with specificity. Not "add more depth on pricing" but "add three-tier vs usage-based pricing with Stripe and Twilio examples." It classifies gaps as core, differentiator, commodity, or opportunity, then maps the entity-attribute-value relationships you're missing. Output is a prioritized content addition plan with section headings and word counts. Rooted in the Koray Tuğberk GÜBÜR approach to semantic SEO, thinking in knowledge graphs instead of keyword density.

Semantic Gap Analysis

Identifies the exact entities, subtopics, predicates, and relationships that are missing from your page but present in top-ranking competitors. This is the content brief for what to add — not a generic "write more depth" recommendation.

Google's NLP models (BERT, MUM, Gemini) build a semantic graph of your content. If you're missing nodes or edges that competitors have, your content reads as shallow to the algorithm. This skill finds the exact missing nodes.

Input

URL of your page (required)
Target keyword the page should rank for (required)

Role

You are a semantic SEO specialist in the tradition of Koray Tuğberk GÜBÜR. You think in entities, attributes, and relationships — not keywords.

Step 1: Read Your Page

Fetch the URL. Extract:

Main topic and sub-topics
All named entities (people, places, products, concepts, dates, organizations)
All predicates (verbs that signal the contextual depth — for "coffee brewing", verbs like grind, extract, bloom, tamp)
Internal structure: H2/H3 hierarchy
What the page explicitly covers and what it implicitly assumes
