Google Labs scores B (89/100) for traditional SEO and A (96/100) for AI and answer-engine visibility, so the site is in strong shape overall. The lower SEO score is almost entirely driven by a weak Search Visibility category (62/100), pulled down by three foundational technical issues: a soft-404 misconfiguration, duplicate-host indexing, and a missing HTTP-to-HTTPS redirect. These gaps don't affect how AI tools read the site today, but they create crawling and duplicate-content risks that hold the SEO grade back.
SEO: correspond au profil des sites bien classés.
AIO: correspond au profil des sites bien classés.
Le seuil de 85 points correspond au score qu'obtiendrait un site appliquant les pratiques des sites systématiquement bien classés sur ces mêmes vérifications — un étalon mesuré, et non un classement en temps réel des concurrents.
Scores par catégorie
Chaque catégorie est un ensemble pondéré de vérifications mesurées ; les catégories non mesurables sont exclues de la note, et non estimées.
Chaque score est construit à partir de catégories pondérées ; la colonne contribution indique précisément combien de points chaque catégorie ajoute au total (les pondérations se renormalisent sur ce qui était mesurable). Les catégories réutilisent les mêmes vérifications sous-jacentes — rien n'est exploré deux fois.

Fix soft 404s so error pages return HTTP 404 status
SEO + AIOTo do
When we requested a deliberately non-existent URL, the server returned HTTP 200 instead of a proper 404 — meaning search engines may treat error pages as real, indexable content. This wastes crawl budget and can dilute the site's authority by surfacing meaningless pages in search indexes. Audit your server or CMS routing rules to ensure any URL that doesn't match a real page returns a true HTTP 404 (or 410 for permanently removed content); this typically helps search engines focus crawling on pages that matter.

Add a discoverable Contact page linked from the homepage
SEO + AIOTo do
We found links to an About page and a Privacy page from the homepage, but no Contact page was detected. Search engines and AI answer engines use trust signals like About, Contact, and Privacy pages to assess site credibility, and a missing Contact link is a common reason authority scores plateau. Adding a Contact page and linking to it clearly from the main navigation or footer typically helps both user trust and quality assessments.

Redirect www or apex to one canonical host consistently
SEO + AIOTo do
Both the www (www.labs.google) and non-www (labs.google) versions of the site currently return HTTP 200 without redirecting to a single preferred host, which means search engines may index the same content under two different addresses. This creates a duplicate-content risk that can split ranking signals and confuse crawlers about which version to treat as authoritative. Choose one canonical host and configure a permanent 301 redirect from the other; this typically helps consolidate any link equity and prevents duplicate indexing.

Redirect all HTTP traffic to HTTPS automatically
SEO + AIOTo do
Our test found that the http:// version of the site did not redirect to https://, leaving open the possibility that both the secure and insecure versions are crawled and indexed separately. Beyond the duplicate-content risk this shares with the canonical-host issue, serving any traffic over plain HTTP is a security concern that browsers and search engines flag negatively. Adding a server-level 301 redirect from http:// to https:// for all URLs typically helps unify signals and ensures visitors always land on the secure version.

Reduce homepage HTML size below 100 KB where possible
SEO + AIOTo do
The homepage HTML document weighs 285 KB before any images or scripts are loaded, which is well above the commonly recommended threshold of around 100 KB for a lean HTML payload. Large HTML documents slow initial parsing, can delay time-to-first-byte on slower connections, and may cause crawlers to truncate content before reaching important elements lower in the page. Review the markup for inline scripts, large inline SVGs, or redundant whitespace that could be moved to external files or minified to bring the document size down.
