XML Sitemap +6 overall pts

Sitemap found at nen.nl/sitemap_index.xml, but bounded integrity checks failed: invalid_xml.

XML Sitemap

HIGH

Sitemaps help AI crawlers discover all your pages efficiently. Without one, crawlers may miss important content or waste time discovering your site structure.

Keep sitemap URLs same-origin, use valid lastmod values, and ensure sampled pages return successful responses.

High-value schema types +5 overall pts

No high-value schema types found. We check for 17 recognized types including Article, Product, SoftwareApplication, FAQPage, LocalBusiness, VideoObject, and more.

High-value schema types

HIGH

Certain schema types (Article, Product, FAQPage, etc.) trigger rich results in Google and Bing and give agents typed, unambiguous entities to extract instead of inferring from prose. Their effect on AI-search citations is indirect, via the search indexes that feed products like ChatGPT and Perplexity.

Add JSON-LD markup for content-appropriate types like Article, Product, SoftwareApplication, FAQPage, LocalBusiness, Service, Event, or VideoObject so agents and search engines can identify your content type and extract structured facts reliably.

JSON-LD html

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "SoftwareApplication",
  "name": "Your App Name",
  "operatingSystem": "Web",
  "applicationCategory": "BusinessApplication",
  "offers": {
    "@type": "Offer",

AI crawler directives +4 overall pts

Mixed AI crawler policies. Disallowed: CCBot. Not mentioned (12): GPTBot, Google-Extended, ChatGPT-User, ClaudeBot, Amazonbot, Claude-User, Bytespider, PerplexityBot, Applebot-Extended, meta-externalagent, Claude-SearchBot, OAI-SearchBot.

AI crawler directives

MEDIUM

Major AI systems use dedicated crawlers (GPTBot, ClaudeBot, Amazonbot). Explicit directives signal whether you want your content included in AI training and search results.

1 AI crawlers are blocked. Consider allowing them to improve AI discoverability.
