What is AI web readiness?

AI web readiness measures how well a website can be discovered, parsed, and cited by AI agents and large language models. It covers signals like /llms.txt, structured data, robots.txt AI crawler permissions, server-side rendering, and OpenGraph metadata.

What is /llms.txt and why does it matter?

/llms.txt is a plain text file placed at the root of a website that tells AI agents what the site is about, what it offers, and which pages to prioritize. Without it, AI agents have to guess your site's structure and purpose. It is the most impactful single change you can make for AI visibility.

How is the AI readiness score calculated?

The score is calculated across 14 weighted checks, each representing a signal that AI agents use when reading, classifying, or citing a website. Points are awarded on a pass/partial/fail basis, then normalized to a 0-100 scale. The checks cover /llms.txt (25 pts), structured data (15 pts), content readability (15 pts), and 11 additional signals.

Is AI readiness the same as SEO?

They overlap but are distinct. Traditional SEO optimizes for search engine crawlers and ranking algorithms. AI readiness optimizes for large language models and AI agents that read, summarize, and cite content directly. Many SEO best practices (structured data, fast load times, clear content) also help AI readiness, but AI-specific signals like /llms.txt have no SEO equivalent.

Which AI crawlers does the tool check for?

The tool checks for explicit permissions in robots.txt for GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, Google-Extended, anthropic-ai, cohere-ai, and meta-externalagent, among others.

Is this tool free to use?

Yes, AI Web Readiness is completely free to use. No account or sign-up is required. Simply enter a URL and get a full report in seconds.

Audit by AI Web Readiness (https://aiwebreadiness.com) on 2026-07-12. Full report: https://aiwebreadiness.com/report/oteFMJyeko
Current score: 58/100 (Fair). 8 of 14 checks at full marks.

## Your task

You are working on the website https://kakuro-puzzle.online. An automated audit measured how well this site can be discovered, parsed, and cited by AI agents and LLM-powered search engines. The issues it found are listed below, ordered by how many points each is worth.

Work through them in order, highest value first. For each issue, make the change in this site's codebase or CMS using the stack and conventions already in use. Where a fix needs copy, facts, or URLs you cannot verify from the existing site, ask me rather than inventing them.

There are 62 weighted points on the table across these 6 issues. Fixing all of them scores 100/100. If you only have time for the top 3, that alone is worth 45 points and takes the score to roughly 88/100.

## Issues to fix (6)

### 1. AI agent manifest (25 points available)

**What the scan found:** No /llms.txt found (status 404).

**Why it matters:** An /llms.txt file tells AI agents exactly what your site is, what it offers, and which pages to prioritize. Without it, agents have to guess.

**How to fix it:** Create a plain text file at /llms.txt in your site root. It should start with a # Title line, a short > description, and a list of your key pages as markdown links. Use the draft generated below as your starting point. It is ready to deploy as-is.

### 2. Full-content AI feed (10 points available)

**What the scan found:** No /llms-full.txt found (status 404).

**Why it matters:** An /llms-full.txt file gives agents your complete site content in one place, so they can understand you without crawling page by page.

**How to fix it:** Create /llms-full.txt at your site root containing the full text of your most important pages, concatenated in order. Each page should be separated by a clear heading. Many static site generators and CMS platforms have plugins that generate this automatically.

### 3. AI crawler permissions (10 points available)

**What the scan found:** robots.txt exists but defines no rules for AI agents (GPTBot, ClaudeBot, etc.).

**Why it matters:** Checks whether your robots.txt explicitly addresses AI agents like GPTBot, ClaudeBot, and PerplexityBot. Silence is ambiguous; explicit rules build trust and control.

**How to fix it:** Add explicit rules for AI crawlers to your /robots.txt file. To allow all AI agents: add "User-agent: GPTBot", "User-agent: ClaudeBot", "User-agent: PerplexityBot", "User-agent: Google-Extended", and "Allow: /" under each. To block specific agents, use "Disallow: /" instead. Each additional agent addressed improves your score.

### 4. Attribution schema (8 points available)

**What the scan found:** No author, publisher, Person, or Organization found in JSON-LD structured data.

**Why it matters:** Structured author, publisher, Person, or Organization data tells AI citation engines who created the content and who stands behind it, directly influencing whether you get credited.

**How to fix it:** Add an author or publisher entity to your JSON-LD. For a business, include an Organization block with name, url, and logo. For content pages, add an author field with a Person type containing name and optionally sameAs links to authoritative profiles (LinkedIn, Wikipedia, official bio page). This is what citation engines use to attribute quotes and facts to you.

### 5. Content feed (6 points available)

**What the scan found:** No RSS or Atom feed detected. A content feed signals an actively updated site that agents should re-index.

**Why it matters:** An RSS or Atom feed signals that your site publishes content regularly and gives agents and aggregators a reliable stream to re-index as you update.

**How to fix it:** Create an RSS or Atom feed at /feed.xml or /rss.xml listing your most recent content with title, link, description, and pubDate per item. Add a <link rel="alternate" type="application/rss+xml" href="/feed.xml"> tag to your <head> so agents can discover it automatically. WordPress, Ghost, and most CMS platforms generate this by default.

### 6. Readable content ratio (3 points available, currently scoring 12 of 15)

**What the scan found:** 12851 chars of text, 9.4% text-to-HTML ratio. Improving content density would raise this score.

**Why it matters:** Measures how much of your page payload is actual text versus markup, scripts, and boilerplate. Low ratios signal bloated or ad-heavy pages that agents deprioritize.

**How to fix it:** Reduce inline scripts and styles, remove unused third-party widgets, and ensure your main content is substantial. Aim for at least 1,500 characters of visible body text and a text-to-HTML ratio above 10%. Moving scripts to external files and deferring non-critical CSS both help significantly.
