What is an AI Visibility Checker?

An AI Visibility Checker analyzes your webpage to determine how likely it is to appear in AI-generated search results from tools like ChatGPT, Google AI Overviews, and Perplexity. It scores your content on factors like structure, clarity, authority signals, and schema markup that AI systems use to select sources.

What is llms.txt and why do I need it?

llms.txt is a new standard file (similar to robots.txt) that tells AI crawlers like GPTBot, ClaudeBot, and PerplexityBot which pages on your site are most important. As AI-powered search grows in 2026, having an llms.txt file helps ensure your most valuable content gets properly indexed and cited by AI systems.

How does the Meta Tag Generator work?

Our Meta Tag Generator uses AI (GPT-4o-mini) to analyze your webpage URL or pasted content and generate optimized meta tags including title tags, meta descriptions, Open Graph tags, Twitter Card tags, and canonical URLs. Each tag is crafted following SEO best practices with proper character limits.

Do I need to sign up to use these tools?

No signup is required for free usage. You can use all 9 tools immediately. Creating a free account lets you save your generation history and access your results across devices. Paid plans unlock unlimited AI generations and additional features.

What is schema markup and why does it matter?

Schema markup is structured data (JSON-LD) that you add to your HTML to help search engines understand your content. It can enable rich snippets in search results like star ratings, FAQ dropdowns, recipe cards, and more. Our Schema Markup Generator creates valid JSON-LD for Article, FAQ, Product, HowTo, and other types.

Our tools are regularly updated to reflect the latest changes in search engine algorithms, AI crawling behavior, and technical SEO requirements.
