Affichage des 10 principaux problèmes. Audit complet avec corrections au niveau du code disponible sur le forfait gratuit.

  • 01
    FAIL · onpage
    Meta Description
    The meta description is missing. Google + Bing + Yandex will fabricate a SERP snippet from random page text — often ending mid-sentence or surfacing irrelevant content. ChatGPT / Claude / Perplexity may quote the description verbatim as a citation snippet; without one, they fall back to less benefit-focused page text. Missing description = lost CTR even when ranking is unchanged.
  • 02
    FAIL · onpage
    HTML <head> completeness
    3 essential head element(s) missing: Character encoding, Meta description, Canonical URL. 10 recommended head element(s) missing: html lang attribute, Open Graph title, Open Graph description, ....
  • 03
    FAIL · onpage
    H1 Heading
    The H1 heading is missing. Google + Bing + Yandex use H1 as a secondary ranking signal (after <title>) to confirm page topic. ChatGPT / Claude / Perplexity also lean on H1 when extracting page summaries for citation — a missing H1 forces them to infer the topic from <title> and body text, often less accurately. Accessibility screen readers also rely on H1 for page-level navigation.
  • 04
    WARN · ai-readiness
    Knowledge Panel Readiness
    Partial knowledge-panel readiness — score 50/100. Missing components: Organization JSON-LD with ≥5 sameAs anchors, visible NAP (name/address/phone). Each missing piece reduces the chance of appearing in Google Knowledge Panel and AI-search citation anchors.
  • 05
    FAIL · security
    Security Headers Grade (Mozilla Observatory)
    Security grade D- (40/100 baseline, Mozilla Observatory rubric). Top issues: Content-Security-Policy header missing (-25); X-Frame-Options + CSP frame-ancestors both missing (-20); X-Content-Type-Options: nosniff missing (-5)
  • 06
    WARN · onpage
    Meta Title
    The <title> tag is short (5 chars). Google and Bing render ~50–65 chars of title in SERPs — a short title leaves SERP real estate unused and weakens keyword signal. AI engines (ChatGPT / Claude / Perplexity) also use <title> as the canonical page label; a short or vague title produces less-recognizable citations.
  • 07
    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.
  • 08
    FAIL · technical
    HTTP Redirects
    HTTP-to-HTTPS redirect is not configured. Users accessing the site via the insecure protocol (http://) are not being redirected to the HTTPS version.
  • 09
    FAIL · performance
    Image Lazy Loading
    None of the 5 images on the page use lazy loading (loading="lazy"). All images are loaded simultaneously when the page opens, significantly slowing down initial load and consuming user bandwidth.
  • 10
    FAIL · security
    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.
