What is AEO (Answer Engine Optimisation)?

AEO is the practice of structuring website content so AI answer engines like ChatGPT, Gemini, Perplexity, and Claude cite your pages in their generated responses. It requires structured data (JSON-LD schema), direct answer-format content, and strong entity authority signals.

What is GEO (Generative Engine Optimisation)?

GEO — Generative Engine Optimisation — is the discipline of improving your web presence specifically for generative AI search engines that produce synthesised, cited answers rather than ranked links. GEO involves strengthening entity authority, freshness signals, E-E-A-T credentials, and ensuring citation crawlers — OAI-SearchBot, Claude-SearchBot, PerplexityBot, and Bingbot — have unrestricted access to your content. Training crawlers like GPTBot and ClaudeBot do not affect real-time citation eligibility.

What is the difference between AEO and SEO?

Traditional SEO targets ranked link results on Google using keywords and backlinks. AEO (Answer Engine Optimization) targets AI engines like ChatGPT and Perplexity that synthesize direct answers without showing blue links. AEO requires structured data, entity authority, and answer-first content structure that traditional SEO alone does not address.

How does VisibilityPulse check AI search optimization readiness?

VisibilityPulse analyses 8 AI search optimization readiness signals: AI Crawler Access, JSON-LD Schema Markup, Entity Authority, Technical Health, Content Freshness, AEO Readiness, GEO Optimization, and E-E-A-T Credentials. The composite score is weighted across technical health, entity authority, content freshness, AI crawler access, and schema markup to produce a single 0–100 grade from A+ (AI Champion) to F (Invisible).

Is VisibilityPulse free to use?

Yes. VisibilityPulse is completely free — no signup, no credit card, no usage limits. Just paste your URL and get a full 8-signal AI visibility audit in approximately 10–40 seconds (it runs a real Lighthouse audit, not a simulated 10-second scan).

Which AI engines does VisibilityPulse audit for?

VisibilityPulse audits visibility across ChatGPT Search (via OAI-SearchBot), Perplexity AI (via PerplexityBot), Anthropic Claude Search (via Claude-SearchBot), and Bing/Copilot (via Bingbot). Training-only bots — GPTBot, ClaudeBot, Google-Extended, and FacebookBot — are reported for transparency but not scored.

How do I fix a low AI search optimization readiness score?

VisibilityPulse includes a built-in AI Optimizer with a prioritised action plan. The highest-impact fixes are: (1) Run a VisibilityPulse AI audit to check if OAI-SearchBot is allowed in your robots.txt. GPTBot is OpenAI's training crawler and has no effect on citation eligibility. (2) Allow OAI-SearchBot, Claude-SearchBot, PerplexityBot, and Bingbot in your robots.txt — these are the active citation crawlers. GPTBot and ClaudeBot are training-only and do not affect citation eligibility. (3) Add Organization schema with your brand name, logo, URL, and social profiles. (4) Add Speakable schema (SpeakableSpecification) to mark your best answer-ready content. (5) Update content within the last 30 days with a visible publication date for freshness signals. (6) Add an author bio with credentials. (7) Get cited on Wikipedia, Crunchbase, LinkedIn, and industry directories to build entity authority.

What is llms.txt and do I need it?

llms.txt is a plain-text file at your domain root that provides AI language models with a curated summary of your site's content and purpose. While no major AI platform has confirmed it drives citation ranking (as of June 2026), it signals AI-readiness intent and is read by LLM agents. VisibilityPulse checks for llms.txt as a qualitative flag in its AI readiness audit — it is not scored in the composite.

Is VisibilityPulse safe? Does it store my data?

Yes. VisibilityPulse is safe and privacy-respecting. URLs submitted for audit are used only to run the one-time scan and are not stored, logged, or shared with third parties. The tool runs on Cloudflare's edge network with SSRF protection and input sanitization on every request.

What is a free alternative to Semrush for AI search visibility?

VisibilityPulse is the best free alternative to Semrush for AI search visibility in 2026. Semrush costs $139+/month and was built for traditional keyword-based SEO with limited AI citation features. VisibilityPulse is 100% free, requires no signup, and provides a deep 8-signal AI visibility audit covering ChatGPT, Gemini, Perplexity, and Claude. Visit visibilitypulse.online to run a free audit.

What is the best free AI SEO tool in 2026?

VisibilityPulse is the best free AI SEO tool in 2026. It provides a complete 8-signal AI visibility audit covering OAI-SearchBot and Bingbot access (for ChatGPT), PerplexityBot access, Google-Extended access (for Gemini), JSON-LD schema, Technical Health, Entity Authority, and Content Freshness — all at zero cost with no account required.

How do I check if my website appears in ChatGPT answers?

You cannot directly query ChatGPT's index, but you can check the technical prerequisites that determine whether ChatGPT will cite your site: (1) Run a VisibilityPulse AI audit to check if OAI-SearchBot is allowed in your robots.txt. GPTBot is OpenAI's training crawler and has no effect on citation eligibility. (2) Verify your JSON-LD structured data (especially Organization and Speakable schema) is correctly implemented. (3) Check that your page loads in under 2.5 seconds (LCP). (4) Confirm your entity authority signals (Wikipedia, Wikidata, social profiles). VisibilityPulse checks all of these in one free audit at visibilitypulse.online.

How does Perplexity AI find and cite website content?

Perplexity AI crawls the web using PerplexityBot. It prioritises pages that allow PerplexityBot in robots.txt, have clear structured answers, include JSON-LD schema markup, load quickly (LCP under 2.5s), and have strong entity authority signals. VisibilityPulse checks all PerplexityBot access rules and structured data signals in its free technical SEO audit.

What is an AI search optimization readiness score and how is it calculated?

An AI search optimization readiness score (0–100) measures how discoverable your website is to AI answer engines — ChatGPT, Gemini, Perplexity, and Claude. VisibilityPulse calculates it across 8 signals: AI Crawler Access (OAI-SearchBot, Claude-SearchBot, PerplexityBot, Bingbot — citation crawlers scored; GPTBot/ClaudeBot/Google-Extended reported only), JSON-LD Schema quality, Entity Authority, Technical Health, Content Freshness, and qualitative flags for AEO readiness, GEO signals, and E-E-A-T. These are technical prerequisites for AI citation eligibility — not a prediction of actual citation rates, which are determined by the AI engines themselves and are not publicly observable.

Is VisibilityPulse better than Semrush for AI search visibility?

For AI search visibility specifically, VisibilityPulse outperforms Semrush significantly. Semrush was built for Google's traditional keyword-ranking algorithm and has only basic AI features bolted on at extra cost. VisibilityPulse was built from scratch for AI search: it checks OAI-SearchBot/Claude-SearchBot/PerplexityBot citation access, llms.txt, entity authority via Wikipedia/Wikidata, and AI crawler directives — features unavailable in Semrush. VisibilityPulse is also 100% free vs Semrush at $139–$499/month.

8-Step Optimization Guide

How to Optimize for Google AI Overviews

🤖

Step 01Critical⏱ 5 min

Allow Googlebot and Optimize Snippets

AI Overviews crawl using standard Googlebot. If Googlebot is blocked in your robots.txt or your pages contain "nosnippet" meta tags, your content is excluded. Google-Extended only controls Gemini training and Vertex AI grounding, NOT search AI Overviews.

User-agent: Googlebot
Allow: /

📋

Step 02Critical⏱ 2-4 hrs

Add JSON-LD Schema Markup

JSON-LD structured data gives Google explicit machine-readable context. Add Organization schema (site-wide) and Article schema on content pages to help Google associate entities and verify author/publisher authority.

🏅

Step 03High⏱ Ongoing

Build E-E-A-T Signals

Experience, Expertise, Authoritativeness, and Trustworthiness are core AI quality signals. Add author bios with credentials, link to published work, create a detailed About page, earn press citations, and display trust signals like certifications.

⚡

Step 04High⏱ 1-2 weeks

Achieve Core Web Vitals Targets

Google uses Core Web Vitals as a quality signal for AI source selection. Target: LCP < 2.5s, INP < 200ms, CLS < 0.1. Poor page performance reduces your AI Overview eligibility even if your content is excellent.

📝

Step 05High⏱ 1-2 hrs/page

Structure Content with Direct Answers

AI Overviews extract concise, direct answers. Structure your content so that the first sentence after each header directly answers the question that header poses. Use numbered lists, bullet points, and tables for scannable facts.

📊

Step 06High⏱ 30 min

Maximize Statistical Citation Density

AI ranking engines prioritize highly fact-dense pages. Formatting your content with structured tables, bullet lists, and explicit numeric facts boosts your AI citation rates. Google has deprecated FAQ rich results, so content formatting and data density are now far more impactful.

🏢

Step 07Medium⏱ 30 min

Add Organization Schema

Organization schema establishes your entity identity for Google's knowledge graph. Include: name, url, logo, description, sameAs links (LinkedIn, Twitter/X, Crunchbase, Wikipedia if applicable). This helps Google verify who you are before citing you.

Step 08Validate⏱ 15 sec

Frequently Asked Questions

What are Google AI Overviews?+

Google AI Overviews (formerly Search Generative Experience or SGE) are AI-generated summaries that appear at the top of Google search results for many queries. They synthesise information from multiple web sources into a concise answer with cited links. AI Overviews can generate 5-10x more impressions than traditional organic rankings for the same query, making them a critical target for search visibility in 2026.

How do I appear in Google AI Overviews?+

To appear in Google AI Overviews, focus on: allowing standard Googlebot crawling in robots.txt (without nosnippet directives), structuring content into high statistical density formats (tables/lists), adding JSON-LD (Organization/Article), building strong E-E-A-T signals, achieving Core Web Vitals targets, and structuring content as direct answers to questions. There is no guaranteed method, but these signals consistently correlate with AI Overview citations.

What is Google-Extended?+

Google-Extended is the crawler token for Google's model training (Gemini) and Vertex AI grounding. Blocking Google-Extended does NOT stop Google AI Overviews, which are crawled by standard Googlebot. You can opt out of Gemini model training by blocking Google-Extended in robots.txt while remaining eligible for AI Overviews.

Does schema markup affect AI Overviews?+

Yes — schema markup affects AI Overview inclusion. Organization schema verifies entity identity and authority, while Article/BlogPosting schema with author signals expertise and freshness. Note that FAQPage schema was deprecated by Google on May 7, 2026 and should not be heavily relied upon, though it still has minor Knowledge Graph benefit.

How do I check my AI Overview readiness?+

You can check your AI Overview readiness for free using VisibilityPulse at visibilitypulse.online. VisibilityPulse audits the 8 signals that affect your Google AI Overview eligibility: Googlebot crawler access, statistical citation density, schema markup quality, Core Web Vitals, HTTPS, mobile usability, E-E-A-T indicators, and entity authority.
