Our Mission
The way people find information is changing fundamentally. Consumers are increasingly turning to AI assistants — ChatGPT, Claude, Gemini, Perplexity — instead of traditional search engines for recommendations, research, and purchasing decisions.
Sigly exists to ensure your business is not left behind in this transition. We provide the tools to measure, monitor, and improve how AI systems understand and recommend your business — a discipline we call Generative Engine Optimization (GEO).
Traditional SEO optimizes for crawlers and ranking algorithms. GEO optimizes for Large Language Models (LLMs) that need to understand your content, not just index it. Sigly bridges this gap with continuous monitoring and actionable coaching.
How Sigly Works
Sigly evaluates your website across 400+ automated checks grouped into 22 categories, covering everything from structured data and content quality to neural readability and agentic actionability.
AI Visibility Pillar
Measures whether AI systems can find, access, crawl, and comprehend your content. Covers crawl coverage, structured data, machine readability, content quality, and neural readability metrics like Transformer Attention Weight and RAG Chunk Integrity.
Agentic Actionability Pillar
Measures whether AI agents can take meaningful actions on your site — navigating forms, understanding conversion paths, and interacting with semantic elements. Includes technical health scoring for performance, accessibility, and trust signals.
The two pillars combine into the Sigly Score — a single 0-100 metric representing your overall AI readiness. Daily scans track your progress over time, verify applied fixes, detect regressions, and provide prioritized coaching recommendations.
