AI Readiness
Technical and authority signals that support AI systems in accessing, understanding, and reusing your content
Some external data sources were unavailable. Score is based on partial data.
Technical Issues
Your site has no structured data — the machine-readable labels that tell AI what your business does, what you offer, and why you're an authority. Without this, AI assistants are much less likely to mention or recommend you.
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "Organization",
"name": "Your Company Name",
"url": "https://yoursite.com",
"description": "Brief description of your business",
"sameAs": [
"https://twitter.com/yourhandle",
"https://linkedin.com/company/yourcompany"
]
}
</script>AI assistants love Q&A content — it's the easiest format for them to extract and quote. Add a Frequently Asked Questions section to your page, and you'll significantly increase your chances of being cited in AI-generated answers.
<script type="application/ld+json">

"@context": "https://schema.org",

"name": "What does your company do?",

"@type": "Answer",
"text": "We provide [your service]. Our solution helps..."
}
}]
}
</script>Your site is missing identity markup that tells AI engines "we are [Company X], and here's what we do." Adding this helps AI assistants recognize your brand as an authority and recommend you by name.

SEO & Technical Issues (18)
Add a Content-Security-Policy header to prevent XSS and injection attacks.
# Nginx:
add_header Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline';" always;
# Apache (.htaccess):
Header set Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline';"
# Next.js (next.config.js headers):
{ key: 'Content-Security-Policy', value: "default-src 'self'; script-src 'self' 'unsafe-inline'" }Found 5 of 18 images without alt attributes. Alt text is critical for accessibility (screen readers) and SEO (image search).
Set X-Content-Type-Options: nosniff to prevent MIME-type sniffing.
# Nginx:
add_header X-Content-Type-Options "nosniff" always;
# Next.js (next.config.js headers):
{ key: 'X-Content-Type-Options', value: 'nosniff' }Set X-Frame-Options to prevent clickjacking attacks.
# Nginx:
add_header X-Frame-Options "SAMEORIGIN" always;
# Next.js (next.config.js headers):
{ key: 'X-Frame-Options', value: 'SAMEORIGIN' }Add a Referrer-Policy header to control information leakage.
# Nginx:
add_header Referrer-Policy "strict-origin-when-cross-origin" always;
# Next.js (next.config.js headers):
{ key: 'Referrer-Policy', value: 'strict-origin-when-cross-origin' }Add a Permissions-Policy header to control browser feature access.
# Nginx:
add_header Permissions-Policy "camera=(), microphone=(), geolocation=()" always;
# Next.js (next.config.js headers):
{ key: 'Permissions-Policy', value: 'camera=(), microphone=(), geolocation=()' }Add a lang attribute to your <html> tag (e.g., lang="en"). This helps search engines and screen readers understand your content's language.
<html lang="en">
<!-- For other languages: lang="es", lang="fr", lang="de", lang="ja", etc. -->Found 2 H1 headings. Best practice is to have exactly one H1 per page for clear content hierarchy.
Your site is missing a sitemap.xml file. Sitemaps help search engines discover and index all your pages. Submit one to Google Search Console.
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>https://yoursite.com/</loc>
<lastmod>2026-03-15</lastmod>
<priority>1.0</priority>
</url>
<url>
<loc>https://yoursite.com/about</loc>
<lastmod>2026-03-15</lastmod>
<priority>0.8</priority>
</url>
</urlset>5 of 18 images have no alt attribute. Screen readers cannot describe these images to visually impaired users.
Heading hierarchy jumps from H1 to H3. Don't skip heading levels — this confuses screen readers and assistive technology.
Some text appears to use light colors that may not have sufficient contrast against the background. WCAG requires a minimum 4.5:1 contrast ratio.
Your HTML is 1037KB. Large HTML documents take longer to parse. Consider lazy loading content or splitting into multiple pages.
3 scripts without async or defer attributes. These block page rendering. Add defer or async to non-critical scripts.
10 images don't use loading="lazy". Add lazy loading to below-the-fold images to improve initial page load.
Add JSON-LD structured data (Schema.org) to help search engines understand your content and earn rich snippets in search results.
Add a 'Skip to main content' link at the top of the page so keyboard users can bypass repetitive navigation.
<!-- Add as the first element inside <body> -->
<a href="#main-content" class="sr-only focus:not-sr-only focus:absolute focus:top-2 focus:left-2 focus:z-50 focus:px-4 focus:py-2 focus:bg-blue-600 focus:text-white focus:rounded">
Skip to main content
</a>
<!-- Add id to your main content area -->
<main id="main-content">
...
</main>Found 35 elements with large inline styles. Move these to external CSS for better caching and maintainability.

What This Score Means for You
Readiness gaps — This Technical Audit found barriers that can make your page harder for AI systems to access, understand, or reuse. It does not measure citations, recommendations, or answer-level visibility.
Security gaps — Missing security headers may flag your site as unsafe in browsers, hurting trust and conversions.
Slow loading — Sites loading in 3+ seconds lose 53% of mobile visitors (Google data).
Most of these issues have simple, copy-paste fixes. Check the code snippets above for quick solutions.
Security score: 20/100
Most security issues are 5-minute fixes — adding HTTP headers to your server config. Check the code fixes above for the exact headers to add — we include copy-paste code for Nginx, Apache, Vercel, and Netlify.
