Every GEO Check, Across 16 Categories
Glippy scores each page with 240+ individual checks grouped into 16 weighted categories - spanning technical readiness, machine readability, citability, agent interactivity, and content quality. Explore what each category measures and how to improve it.
Technical & structural readiness
Ten categories cover whether AI crawlers and agents can reach, parse, and act on your pages. Each links to a dedicated guide with the exact checks Glippy runs.
Structured Data & Schema 1.5x
JSON-LD, Schema.org types, Speakable markup, and sameAs references.
Semantic HTML 1.2x
Heading hierarchy, semantic elements, and content-to-markup ratio.
Accessibility for Agents 1.0x
Lang attributes, alt text, ARIA landmarks, link text, and form labels.
Internal Linking 1.0x
Link density, navigation structure, breadcrumbs, and anchor links.
Meta & Discoverability 1.0x
Title, description, canonical URLs, Open Graph tags, and hreflang.
Machine Readability 1.5x
SSR, bot blocking, robots, llms.txt, Content-Signal, Link headers, RSL licensing, and IndexNow.
Entity & Authority 1.0x
Author info, publication dates, organization signals, and trust pages.
Citability & Answer-Readiness 1.3x
FAQs, tables, lists, and lead paragraphs that make content easy to cite.
Performance & Crawlability 0.3x
Image dimensions, lazy loading, render-blocking scripts, and DOM size.
Agent Interactivity (WebMCP) 0.2x
WebMCP tools, MCP/A2A discovery, AP2 payments, Agent Skills, NLWeb, schemamap, and Web Bot Auth.
Content quality
Six categories evaluate whether your writing earns citations once AI can read it - the substance, sourcing, and structure that LLMs reward.
Content Positioning 1.2x
Brand differentiation, proof points, social proof, and value props.
Content Freshness 0.8x
Machine-readable dates, recency, copyright year, and version signals.
Information Density 1.0x
Substance vs filler, claim-evidence pairing, and chunk-readiness.
Factual Verifiability 0.8x
Citations, source attribution, and methodology disclosure.
Content Comprehensiveness 0.8x
Topic depth, heading coverage, definitions, and comparisons.
Multimodal Content 0.5x
Alt text, captions, transcripts, SVG titles, and media schema.
Beyond the score: live AI crawler access
Every category above is graded from the page itself. The live AI crawler access check instead measures your server: on demand, Glippy sends 12 real requests for the same URL from one IP, differing only in User-Agent, and reports which AI crawlers were served and which were refused. Because a lone 403 can just mean a bad IP reputation, only a difference between those same-IP requests counts as evidence, and the check says "could not tell" rather than guessing. It runs in the Chrome extension and as the check_agent_access tool in the MCP server.

How scoring works
Each category is scored 0-100 from its individual checks, then combined with the weights shown above into a single GEO score and an A-F grade. Higher-weight categories like Structured Data and Machine Readability move your score the most; emerging-standard checks (WebMCP and the agent-discovery surfaces) are scored as a bonus, so they lift your score when present without penalizing you when absent. For the complete, itemised list of every check, see the full check reference.
