ChatGPT Search Optimization Checker — See If ChatGPT Recommends Your Website
A ChatGPT search optimization checker analyses whether your website is technically and structurally optimised for ChatGPT citations. VisibilityPulse checks the signals that matter most for ChatGPT: OAI-SearchBot crawler access in robots.txt, JSON-LD schema quality, entity authority, content freshness, E-E-A-T signals, and Core Web Vitals. Your ChatGPT search optimization readiness is scored 0–100 with a grade and fix list. Free. No signup. Results in ~10–40 seconds.

VisibilityPulse fetches your robots.txt and checks whether OpenAI's OAI-SearchBot crawler is explicitly allowed or blocked. If OAI-SearchBot is blocked, ChatGPT Search cannot crawl or cite your pages — this is the single most critical check for ChatGPT visibility.
Schema Validation for ChatGPT
JSON-LD structured data helps ChatGPT understand your entity, content type, and relationships. VisibilityPulse validates your schema against best practices and identifies missing or malformed markup that reduces your citation probability.
Entity Authority Score
ChatGPT favours websites with strong, unambiguous entity identity. VisibilityPulse scores your entity authority based on Organisation schema, consistent NAP data, clear authorship signals, and external entity recognition indicators.
Why ChatGPT Visibility Matters in 2026
ChatGPT has over 200 million weekly active users and is increasingly used as a primary search interface. ChatGPT Search — OpenAI's real-time web search feature — surfaces website citations directly in chat responses. If your website is not optimised for ChatGPT, you are invisible to a growing segment of high-intent users.
Unlike traditional SEO, ChatGPT visibility depends on a distinct set of technical signals. The most critical is OAI-SearchBot access — if your robots.txt blocks OAI-SearchBot, ChatGPT Search cannot read or cite your content. (GPTBot only affects training data, not search.) Beyond crawl access, ChatGPT assesses schema quality, entity clarity, E-E-A-T signals, and content structure to decide which pages to cite in its answers.
The 6 ChatGPT Visibility Signals VisibilityPulse Audits:
- OAI-SearchBot Access — Is OpenAI's citation crawler allowed in robots.txt?
- JSON-LD Schema Quality — Is your structured data complete and valid?
- E-E-A-T Signals — Do you demonstrate expertise, experience, and trust?
- Entity Authority — Is your brand/entity clearly defined for AI models?
- Content Freshness — Is your content recently updated?
- Core Web Vitals — Does your site meet Google's performance thresholds?
VisibilityPulse scores each signal individually and combines them into a single ChatGPT Search Optimization Readiness Score (0–100). You receive a grade (A–F), signal-by-signal breakdown, and a prioritised fix list ranked by impact — so you know exactly what to fix first.
OAI-SearchBot vs GPTBot: What Is the Difference?
OpenAI uses two separate crawlers. Many webmasters block both, which removes their site entirely from ChatGPT Search. Understanding the difference between training crawlers and citation search crawlers is essential for modern search visibility.
| Feature | OAI-SearchBot | GPTBot |
|---|---|---|
| Primary Function | Powers real-time search citations inside ChatGPT Search | Collects training data to build future GPT foundation models |
| User-Agent Token | OAI-SearchBot | GPTBot |
| Crawl Speed & Depth | Real-time, incremental (follows users queries) | Batch crawl, high-throughput database builds |
| Impact if Blocked | ❌ Site is completely invisible in ChatGPT Search citations | ⚠️ Site content is not used to train future OpenAI models |
| Robots.txt Example | Allow: / (to enable search citation) | Disallow: / (to restrict training data) |
If you want users to discover your brand through ChatGPT Search, you must configure your robots.txt to explicitly allow OAI-SearchBot. If you wish to protect your intellectual property from model training, you can safely block GPTBot.

What is ChatGPT Search visibility and why is it important?+
ChatGPT Search visibility measures the technical likelihood of OpenAI's real-time search agent surfacing your website as a clickable reference citation. Unlike traditional SEO, which optimizes for keyword match lists, ChatGPT Search evaluates structural signals: OAI-SearchBot access rules in robots.txt, schema graph completeness (Organization/Article), entity validation links (Wikidata/LinkedIn/Crunchbase), E-E-A-T credentials, and Core Web Vitals. Optimizing these signals ensures you capture traffic from direct AI answers.
How does ChatGPT decide which websites to cite as sources?+
OpenAI uses a specialized web index compiled by OAI-SearchBot and supplemented by Bingbot. When a user enters a query, ChatGPT Search crawls relevant pages and selects sources that load fast (LCP under 2.5s), have rich JSON-LD schema describing their entity relations, maintain high freshness (recent dateModified updates), and have verified external authority (Wikidata sameAs references). VisibilityPulse tests these prerequisites.
What is the difference between OAI-SearchBot and GPTBot?+
They are distinct OpenAI crawlers: OAI-SearchBot (user agent: OAI-SearchBot) crawls in real-time to index pages specifically for ChatGPT Search citations. GPTBot (user agent: GPTBot) crawls in bulk to gather training data for building future models. You can safely block GPTBot to protect your IP from training without affecting your ChatGPT Search citation eligibility — provided OAI-SearchBot remains allowed.
How do I get my website cited by ChatGPT Search?+
The checklist includes: (1) Add explicit User-agent: OAI-SearchBot Allow: / rules to your robots.txt. (2) Implement valid JSON-LD Organization schema with sameAs pointing to Wikidata, LinkedIn, and Crunchbase. (3) Publish fresh content with valid dateModified sitemap entries. (4) Answer niche questions directly and concisely in the first 50 words of your pages. (5) Optimize Core Web Vitals to pass speed audits.
