🚀 Antigravity SEO

The Next-Generation SEO & GEO Skill for Antigravity & Google Gemini.
Technical SEO · Core Web Vitals (INP/LCP/CLS) · E-E-A-T · Schema.org JSON-LD (2026 Standards) · GEO (AI Overviews & Gemini Citability) · Agentic Browsing & llms.txt.

🌟 Why Antigravity SEO?

Most traditional SEO audit tools are still anchored in 2020: they measure outdated metrics (like FID instead of INP), fail to account for Google's latest rich-result deprecations (such as the removal of FAQPage rich results in May 2026), and ignore the reality of AI Search (GEO / AEO).

Antigravity SEO is purpose-built from the ground up for the Antigravity agentic environment and Google Gemini:

• 🤖 Designed Exclusively for Antigravity & Gemini: Leverages Antigravity's native tools (browser_subagent, run_command, read_url_content) to perform in-depth DOM inspections, headless crawls, and local source code audits.
• ⚡ 2026 Core Web Vitals Compliance: Real-world evaluation of INP (< 200ms), LCP (< 2.5s), and CLS (< 0.1).
• 🏷️ Schema.org 2026 Standards: Immediate detection of deprecated schemas (FAQPage, HowTo, SpecialAnnouncement) and generation of modern, connected @graph JSON-LD models.
• 🧠 GEO / AEO Citability Engine: Evaluates passage citability (40–80 words standalone response blocks) for Google AI Overviews, Gemini, and Perplexity.
• 🌐 Agent Readiness: Verifies semantic form markup, ARIA access, and llms.txt formatting for autonomous AI agents.
• 🎯 Falsifiable Action Plans: Every recommendation includes a concrete observation, leading indicator, and an explicit test to detect failure.
