How Grammarly Looks on AI Platforms
Grammarly's score is calculated based on: website structure and schema markup, content accessibility for LLMs, clarity of product/service descriptions, FAQ coverage and structured data, integration documentation, and pricing transparency.
How accessible is Grammarly?
Grammarly's website is highly structured with detailed product pages, transparent pricing, a comprehensive support center, and extensive documentation. The site uses clean HTML, proper heading hierarchy, and accessible metadata. However, some gated content (enterprise pricing, certain case study details) reduces full transparency for AI crawlers.
How easy is it for LLMs to understand Grammarly's mission?
Grammarly's mission - to improve lives by improving communication - is clearly articulated across all touchpoints. Product descriptions, use cases, and success stories consistently reinforce the value proposition with concrete metrics like time saved and error reduction rates that LLMs can parse and summarize accurately.
