Free Online Visibility Checker — Score Your Search & AI Visibility
Find out how visible your website is across Google Search, ChatGPT Search, Perplexity, and Google AI Overviews. Enter your domain below to run an instant, live 8-signal audit with a comprehensive 0–100 visibility readiness score.
What Is Online Search Visibility in 2026?
Online visibility in 2026 is no longer just about where your blue links appear on a static Google search results page. Today, high online visibility requires a dual-engine architecture: dominating traditional search engine rankings while securing primary citations in generative AI answer engines (ChatGPT, Perplexity, Gemini, and Google AI Overviews).
A high Online Visibility Score confirms that your website is technically accessible to crawlers, structured with rich machine-readable Schema.org triples, anchored in global knowledge graphs, and engineered for sub-second Core Web Vitals speed.
The 8 Signals That Determine Your Online Visibility Score
VisibilityPulse evaluates your website against eight weighted technical dimensions sourced directly from live HTTP crawls and PageSpeed APIs:
1. AI Crawler Access
Audits your robots.txt file for explicit permissions granted to OAI-SearchBot, PerplexityBot, Claude-SearchBot, and Googlebot.
2. JSON-LD Schema Graph
Validates structured data schemas including Organization, Article, FAQPage, and LocalBusiness for knowledge graph disambiguation.
3. Core Web Vitals
Executes a live Google Lighthouse audit measuring Largest Contentful Paint (LCP < 2.5s), Cumulative Layout Shift (CLS = 0.00), and mobile responsiveness.
4. Entity Authority
Queries Wikipedia and Wikidata entity records to determine if your brand has established authoritative entity recognition in global knowledge bases.
5. llms.txt Standard
Checks for the presence of /llms.txt adhering to the official llmstxt.org standard, enabling fast token-efficient LLM ingestion.
6. Open Graph & Social
Verifies complete Open Graph (og:title, og:description, og:image) and Twitter Cards for social media and AI preview synthesis.
7. Security Headers & SSL
Checks HSTS preloading, Content-Security-Policy (CSP), and TLS 1.3 encryption to protect user privacy and prevent crawl blocking.
8. Canonical & Hreflang
Ensures canonical links prevent duplicate content cannibalization and hreflang tags route international visitors to regional versions.

Frequently Asked Questions About Website Visibility
What is an online visibility checker?
An online visibility checker is an automated diagnostic tool that calculates how readily search engines (Google, Bing) and generative AI answer engines (ChatGPT Search, Perplexity, Google AI Overviews, Gemini) discover, index, and cite your website. It scores your technical foundation, robots.txt crawler access, structured JSON-LD schema, Core Web Vitals performance, and knowledge graph entity authority.
How is the Online Visibility Score calculated?
VisibilityPulse calculates an aggregate 0–100 Online Visibility Score across 8 weighted technical dimensions: AI Crawler Permissions in robots.txt (15%), Schema.org Entity Hierarchy (20%), Core Web Vitals / Performance (20%), Entity Authority in Knowledge Graphs (15%), Content Freshness (10%), Open Graph & Social Cards (10%), and HTTP/3 Security Headers (10%).
How is AI search visibility different from traditional SEO visibility?
Traditional SEO visibility measures your ranking position among the 10 blue links on a Google SERP based on keywords and backlinks. AI search visibility (AEO & GEO) measures whether large language models extract and cite your website as a definitive factual answer in AI-synthesized responses (like ChatGPT Search and Google AI Overviews).
Why does my website have high search impressions but 0 clicks?
A high impression count with zero clicks typically indicates a ranking depth problem. Google indexes your page for relevant keywords, but displays it on Pages 6 to 9 (positions 60–80). Because over 95% of organic clicks occur on Page 1 (positions 1–10), impressions register during automated or paginated searches, but user clicks remain near zero until you optimize on-page content depth and push rankings into the Top 10.
How do I check my website visibility for free?
Enter your domain URL into the VisibilityPulse Online Visibility Checker above. The tool automatically fetches your robots.txt, parses your Schema.org graph, runs a real Google PageSpeed Insights test, queries Wikidata knowledge graphs, and checks crawler access in ~10–40 seconds with zero signup required.
How can I improve my website visibility score?
To improve your score: (1) Whitelist OAI-SearchBot and PerplexityBot in robots.txt, (2) Add complete JSON-LD Organization and Article schemas, (3) Format core answers in the first 40 words of key sections, (4) Optimize Core Web Vitals to achieve 0.00 CLS and sub-2.5s LCP, and (5) Build an official llms.txt file following the llmstxt.org specification.
