GEO Platform Optimizer

Core Insight

Only 11% of domains are cited by BOTH ChatGPT and Google AI Overviews for the same query. Each AI search platform uses different indexes, ranking logic, and source preferences. A page optimized for Google AI Overviews may be invisible to ChatGPT, and vice versa. Platform-specific optimization is not optional — it is the foundation of any serious GEO strategy.

How to Use This Skill

1. Collect the target URL and the site's primary topic/industry
2. Run each platform checklist below against the site
3. Score each platform on the 0-100 rubric
4. Generate GEO-PLATFORM-OPTIMIZATION.md with per-platform scores, gaps, and action items

Platform 1: Google AI Overviews (AIO)

How AIO Selects Sources

• 92% of AIO citations come from pages already ranking in the top 10 organic results — traditional SEO is the gateway
• However, 47% of citations come from pages ranking below position 5 — AIO has its own selection logic favoring clarity and directness over raw rank
• AIO strongly favors pages with clean structure, direct answers, and scannable formatting
• Featured snippet optimization has ~70% overlap with AIO optimization
• AIO prefers concise, factual, unambiguous answers — hedging and filler reduce citation probability

Optimization Checklist

1. Question-Based Headings: Use H2/H3 headings phrased as questions matching real user queries. Check Google's "People Also Ask" for the target topic and mirror those exact phrasings.
2. Direct Answer in First Paragraph: After each question heading, provide a clear 1-2 sentence answer immediately. Then expand with supporting detail. The first sentence should be a standalone citation candidate.
3. Tables and Structured Comparisons: AIO heavily cites tables. Convert any comparison, pricing, specification, or feature data into HTML tables. Use clear column headers.
4. Ordered and Unordered Lists: Step-by-step processes should use ordered lists. Feature lists should use unordered lists. AIO extracts these directly.
5. FAQ Sections: Add a dedicated FAQ section with 5-10 real questions. Use proper H3 headings for each question. While FAQPage schema rich results are restricted to govt/health sites since Aug 2023, the content pattern still helps AIO extraction.
6. Definitions and Glossary Boxes: For any industry-specific term, provide a clear definition. Format: "[Term] is [concise definition]." AIO frequently cites definitions.
7. Statistics with Sources: Include specific numbers with attribution. "According to [Source], [statistic]." AIO prefers citeable, specific claims over vague assertions.
8. Publication Date: Include a visible publication date and last-updated date. AIO deprioritizes undated content for time-sensitive queries.
9. Author Byline: Display author name with credentials. Link to an author page with bio, credentials, and sameAs links.
10. Page Depth: Keep target pages within 3 clicks of homepage. AIO rarely cites deep, orphaned content.

Platform 2: ChatGPT Web Search

How ChatGPT Selects Sources

• Uses Bing's search index as its foundation (not Google)
• Top citation sources by domain share: Wikipedia (47.9%), Reddit (11.3%), YouTube, major news outlets
• ChatGPT heavily weights entity recognition — if your brand exists as a structured entity (Wikipedia, Wikidata, Crunchbase), it is far more likely to be cited
• Prefers authoritative, well-established sources over new or niche sites
• Longer, more comprehensive articles get cited more often than short pieces
• ChatGPT tends to cite the most canonical source for a claim rather than the original

Optimization Checklist

1. Wikipedia Presence: Check if the brand/person/product has a Wikipedia article. If not, assess notability criteria. If notable, create a draft. If an article exists, ensure it is accurate and current.
2. Wikidata Entity: Verify the entity exists on Wikidata (wikidata.org). If not, create a Wikidata item with key properties: instance of, official website, social media links, founding date, headquarters location.
3. Bing Webmaster Tools: Verify the site is registered in Bing Webmaster Tools. Submit sitemap. Check for crawl errors.
4. Bing Index Coverage: Use site:domain.com on Bing to verify key pages are indexed. Bing may have different indexed pages than Google.
5. Reddit Authority: Check for brand mentions on Reddit. Identify relevant subreddits. Assess whether the brand participates authentically in discussions.
6. YouTube Presence: Verify YouTube channel exists with relevant content. Video descriptions should contain full URLs and entity information.
7. Authoritative Backlinks: ChatGPT/Bing weight .edu, .gov, and major publication backlinks heavily. Audit backlink profile for these sources.
8. Entity Consistency: Brand name, founding date, leadership, and key facts must be consistent across Wikipedia, Crunchbase, LinkedIn, and the official website.
9. Comprehensive Content: Pages targeting ChatGPT citation should be 2000+ words with thorough topic coverage. ChatGPT prefers single authoritative sources over combining multiple thin pages.
10. Clear Attribution: Include "About" sections, company descriptions, and founding stories. ChatGPT uses these for entity grounding.

Platform 3: Perplexity AI

How Perplexity Selects Sources

• Top citation sources: Reddit (46.7%), Wikipedia, YouTube, major publications
• Perplexity places the heaviest emphasis on community validation of all AI search platforms
• Strongly favors discussion threads where claims are debated, validated, or expanded by multiple participants
• Prefers recent content — publication date is a strong ranking signal
• Cites multiple sources per answer (typically 5-15), so there is more opportunity for mid-authority sites to appear
• Uses its own crawling infrastructure in addition to search APIs

Optimization Checklist

1. Active Reddit Presence: The brand or its representatives should participate authentically in relevant subreddit discussions. Not promotional — helpful, specific, and community-oriented.
2. Reddit AMAs and Threads: Encourage or participate in AMAs, detailed discussion threads, and community Q&As. Perplexity treats these as high-signal content.
3. Forum and Community Presence: Beyond Reddit, check Hacker News, Stack Overflow, Quora, and niche industry forums. Perplexity indexes these heavily.
4. Discussion-Friendly Content: Publish content that invites discussion — opinion pieces, research findings, contrarian takes, original data. Content that gets shared and debated in communities ranks higher.
5. Freshness Signals: Publish content with clear dates. Update content regularly. Perplexity deprioritizes stale content more aggressively than other platforms.
6. Multiple Source Validation: Claims in your content should be supported by other sources. Perplexity cross-references and prefers claims it can verify from multiple origins.
7. YouTube Video Content: Create video content that Perplexity can reference. Ensure video titles, descriptions, and transcripts contain target information.
8. Direct, Quotable Passages: Write paragraphs that can stand alone as citations. Each paragraph should make one clear point with supporting evidence.
9. Original Data and Research: Publish original surveys, benchmarks, case studies, or datasets. Perplexity heavily favors primary sources.
10. Perplexity Pages: Check if Perplexity has created a "Page" about your topic/brand. These are curated summaries that influence future citations.

Platform 4: Google Gemini

How Gemini Selects Sources

• Uses Google's search index plus strong weighting toward Google-owned properties
• YouTube content is weighted significantly more heavily than in standard Google Search
• Google Business Profile data is directly accessible to Gemini
• Gemini uses Google's Knowledge Graph directly — entity presence in Knowledge Graph is a major advantage
• Structured data (Schema.org) is consumed directly by Gemini for entity understanding
• Gemini multi-modal: can reference images, videos, and text together

Optimization Checklist

1. Google Knowledge Panel: Check if the brand has a Google Knowledge Panel. If not, claim it through Google Business Profile or structured data. Ensure all information is accurate.
2. Google Business Profile: Complete and optimize GBP with all fields: hours, services, photos, posts, Q&A. Gemini pulls directly from GBP for local queries.
3. YouTube Strategy: Create YouTube content for every key topic. Optimize titles, descriptions, timestamps, and closed captions. Gemini cites YouTube more than any other AI platform.
4. YouTube Chapters and Timestamps: Use chapters (timestamps in description) so Gemini can reference specific segments of videos.
5. Google Merchant Center: For e-commerce, ensure products are in Google Merchant Center. Gemini references product data directly.
6. Structured Data (Schema.org): Implement comprehensive Schema.org markup. Gemini uses this for entity understanding more aggressively than other platforms.
7. Google Sites Ecosystem: Ensure presence across Google ecosystem: Google Scholar (for research), Google News (for publishers), Google Maps (for local).
8. Image Optimization: Gemini is multi-modal. Use descriptive alt text, structured image filenames, and high-quality images. Include relevant images with every piece of content.
9. Google E-E-A-T Signals: All standard Google E-E-A-T signals apply with extra weight. Author pages, about pages, editorial policies, and expertise demonstrations.
10. Chrome Web Store / Google Workspace Marketplace: For software companies, presence on Google platforms adds entity signals.

Platform 5: Bing Copilot

How Copilot Selects Sources

• Uses Bing's search index (shared infrastructure with ChatGPT but different ranking/selection)
• Supports IndexNow protocol for near-instant indexing of new and updated content
• Copilot tends to cite fewer sources per answer (typically 3-5) but gives more prominent attribution
• Microsoft ecosystem integration: LinkedIn, GitHub, Microsoft Learn content is weighted
• Copilot prefers pages with clear, structured markup and fast load times

Optimization Checklist

1. Bing Webmaster Tools: Register and verify site. Submit XML sitemap. Review and fix any crawl issues.
2. IndexNow Implementation: Implement the IndexNow protocol to notify Bing of content changes in real-time. Submit a key file at /.well-known/indexnow-key.txt and ping the IndexNow API on content publish/update.
3. LinkedIn Company Page: Ensure the company LinkedIn page is complete with accurate description, employee connections, and regular posts. Copilot indexes LinkedIn content.
4. GitHub Presence: For tech companies, maintain an active GitHub presence. Copilot references GitHub repos, documentation, and README files.
5. Microsoft Learn / Documentation: If relevant, contribute to Microsoft Learn or ensure documentation is compatible with Microsoft's documentation standards.
6. Bing Places for Business: Equivalent to Google Business Profile. Complete all fields for local search visibility in Copilot.
7. Clear Meta Descriptions: Bing/Copilot weights meta descriptions more heavily than Google does. Write compelling, keyword-rich meta descriptions for every page.
8. Social Signals: Bing has historically weighted social signals (shares, likes, engagement) more than Google. Maintain active social media presence.
9. Exact-Match Keywords: Bing's algorithm is more literal about keyword matching than Google. Include exact target phrases in titles, headings, and body content.
10. Fast Page Load: Copilot deprioritizes slow pages. Target sub-2-second load time. Optimize images, enable compression, minimize render-blocking resources.
