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

  • 01
    WARN · technical
    Robots.txt
    The robots.txt file was found but does not contain a Sitemap directive. The Sitemap directive helps search engine crawlers discover all pages on your website more efficiently.
  • 02
    FAIL · performance
    Time to First Byte (TTFB)
    Time to First Byte is 2363 ms (2.36 sec) — Google flags this as "poor" (> 1.8 s per web.dev/articles/ttfb). The browser cannot begin rendering until the first byte arrives, so LCP cannot beat 2.36s. Every downstream Core Web Vital (LCP, INP, CLS) inherits this delay, and Page Experience signals trigger a soft demotion in Google + Bing rankings.
  • 03
    FAIL · onpage
    HTML <head> completeness
    1 essential head element(s) missing: Canonical URL. 2 recommended head element(s) missing: Apple touch icon, Theme color.
  • 04
    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.
  • 05
    FAIL · performance
    Images Inventory (Deep)
    Inventoried 85 <img> elements (20 HEAD-probed, 0 responsive, 82 lazy-loaded). Approx 6711 KB of probed image weight. 7 images larger than 500 KB.
  • 06
    WARN · onpage
    Meta Title
    The <title> tag is short (12 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
    WARN · technical
    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.
  • 09
    FAIL · technical
    WWW Canonicalization
    WWW/non-www canonicalization is not configured. The site is accessible at both addresses (ycombinator.com and www.ycombinator.com), which results in duplicate content. Search engines may index both versions and split link equity between them.
  • 10
    FAIL · performance
    Render-Blocking Resources
    Found 26 render-blocking resources (25 CSS, 1 JS) — this is too many. The browser must download and process all of these files before it can start rendering the page. This critically delays First Contentful Paint (FCP) and Largest Contentful Paint (LCP).
