Reverse-engineer WHY certain pages get cited by Gemini — and build a blueprint to replicate their success.

Background

Influence over AI answers happens at retrieval, not inside the model. You can't edit Gemini's weights, but you can enter the candidate set it selects from when it searches the web. Every prompt triggers a retrieval step — Gemini fires search queries, evaluates the results, and picks sources to ground its answer. The pages it picks consistently form the recurring retrieval set for that topic.

This skill profiles the pages inside that recurring set. By analyzing what they have in common — length, structure, schema, freshness, entity density — you get a concrete blueprint for what it takes to enter and stay in the candidate set. Gemini's search-first architecture creates more entry points than recall-first models like GPT, which means the on-page profile of cited sources matters more than ever: retrievability requires alignment with query patterns, comprehensive coverage, and structural clarity.

Why This Works

Not all pages are created equal. When Gemini answers a prompt, it consistently cites certain sources over others. This skill reveals the common profile of those cited pages: their length, structure, schema markup, freshness, and entity density. By running 20 samples, you see which sources are reliably part of the recurring retrieval set (not just lucky once), then by profiling those pages, you discover the on-page signals that correlate with AI citation.

The result is a citation blueprint — a concrete spec for what your content needs to look like to enter the candidate set for that prompt. Influence compounds through repeated inclusion; one-off citations don't matter, but matching the blueprint puts you in the recurring set.

Defaults

• Model: gemini-3-flash-preview — the same model powering Google AI Overviews
• Samples: 20 runs per prompt — captures probabilistic citation patterns
• Top pages: 10 — profiles the 10 most-cited URLs

Requirements

• Gemini API key (free from aistudio.google.com) — set as GEMINI_API_KEY env var
• Python 3.9+
• No pip dependencies (stdlib only)

Usage

# Basic — profile top-cited sources for a prompt
GEMINI_API_KEY="$GEMINI_API_KEY" python3 scripts/profile.py "best project management tools for startups"

# Highlight how your domain compares to the blueprint
GEMINI_API_KEY="$GEMINI_API_KEY" python3 scripts/profile.py "best project management tools for startups" --domain monday.com

# Profile more pages with higher confidence
GEMINI_API_KEY="$GEMINI_API_KEY" python3 scripts/profile.py "best CRM software" --domain hubspot.com --runs 30 --top 15

# JSON output for programmatic use
GEMINI_API_KEY="$GEMINI_API_KEY" python3 scripts/profile.py "best SEO tools" --output json

Options

| Option | Default | Description | |--------|---------|-------------| | prompt | (required) | The query to analyze | | --domain | (none) | Domain to highlight vs the blueprint (e.g., example.com) | | --runs | 20 | Number of Gemini runs | | --model | gemini-3-flash-preview | Gemini model to use | | --top | 10 | Number of top URLs to fetch and profile | | --concurrency | 5 | Max parallel requests (keep ≤5 to avoid rate limits) | | --output | text | Output format: text or json |

JSON Output

Structured JSON with profiles (per-page data), blueprint (aggregate pattern), and domain_analysis (if domain provided).

How It Works

1. Phase 1 — Citation Collection: Sends the prompt to Gemini 20 times with Google Search grounding. Extracts all cited URLs from grounding chunks and ranks by frequency.
2. Phase 2 — Page Profiling: Fetches the top 10 most-cited URLs using urllib. For each page, parses HTML to extract:

• Word count (visible body text)
• Headings (H1, H2, H3 counts)
• JSON-LD structured data (types like Article, FAQ, Product)
• Publication and modification dates from meta tags
• Entity density (proper nouns, numbers, statistics, quoted terms)

1. Phase 3 — Blueprint Generation: Aggregates page profiles into a "citation blueprint" — averages, ranges, and common patterns across all profiled pages.
2. Phase 4 — Domain Analysis: If --domain provided, compares that domain's pages against the blueprint, showing where they exceed or fall short.

Tips

• Use the blueprint as a content spec — match the word count, heading structure, and entity density of pages in the recurring retrieval set
• If your domain isn't in the top results, the blueprint tells you what to aim for to enter the candidate set
• Pages with JSON-LD schema (especially Article, FAQ) get cited more often — use aeo-schema to add it
• Run for your most important prompts and compare blueprints — different query types may need different content profiles
• Pair with aeo-content-free to create content that matches the blueprint
• Pair with aeo-ai-overview-simulator for deeper citation rate tracking over time
• Pair with aeo-multi-prompt-strategy to find pages that enter the recurring retrieval set across multiple prompts

Notes

• Gemini API key stored in macOS Keychain under google-api-key
• Pages that fail to fetch (timeouts, 403s) are noted but don't crash the analysis
• HTML parsing uses stdlib html.parser — no external dependencies
• Retries API calls up to 5 times with exponential backoff
• Page fetching uses a 10-second timeout to avoid slow pages blocking the analysis
