  FAIL · technical

  Canonical Tag

  The canonical tag is missing. Without <link rel="canonical">, Google + Bing + Yandex may index multiple URL variants of the same content (with/without trailing slash, with tracking parameters like ?utm_source=, http vs https) and split link equity across the duplicates. AI search engines (ChatGPT / Claude / Perplexity) may also cite the wrong URL variant, fragmenting the citation graph for your content.

  WARN · technical

  Robots.txt

  The robots.txt file exists but does not contain a User-agent: * block. While specific bots may be configured, most search engine crawlers look for wildcard rules.

  XML Sitemap

  The sitemap.xml file was not found at /sitemap.xml. Without a sitemap, Google + Bing + Yandex must rely on internal-link discovery to find your pages — recently published or orphan content may not be indexed for weeks. AI search engines (ChatGPT search via OAI-SearchBot, Claude search, Perplexity) also crawl sitemap.xml to discover content, so missing sitemaps delay AI citation as well.

  HTTP Redirects

  WWW canonicalization is not configured. The site is accessible with both www and non-www addresses simultaneously, which leads to duplicate content issues for search engines.

  WWW Canonicalization

  WWW/non-www canonicalization is not configured. The site is accessible at both addresses (melottogroup.com and www.melottogroup.com), which results in duplicate content. Search engines may index both versions and split link equity between them.

  Browser Caching

  Security Headers

  Only 1 out of 6 modern security headers found. Missing: x-frame-options, x-content-type-options, content-security-policy, referrer-policy, permissions-policy. The site is exposed to XSS (no CSP), clickjacking (no X-Frame-Options / CSP frame-ancestors), MIME-sniffing (no X-Content-Type-Options), and HTTPS-stripping MITM (no HSTS). Mozilla Observatory grades sites with <4 headers as D or F.
