The "Related Keywords Test" tool from TeckBlaze analyzes words semantically linked to your main topic in real time. You enter a URL above, we fetch the page exactly as Googlebot would, isolate the tested element, compare it to 2026 best practices, and tell you in plain words whether it passes, needs work, or is critical.
Why related keywords test still matters in 2026
Keyword choice and density signal to Google what your page is actually about. Without semantic consistency, Google may rank the page for irrelevant queries — or not rank it at all.
The newer reason: AI answer engines and link previews
AI engines rely on semantic consistency to understand your expertise. Scattered vocabulary makes the page seem unfocused — and the AI will prefer a clearer source.
Common mistakes worth checking
Vocabulary spread across multiple intents.
Over-optimization (density > 5%) triggering a spam signal.
Fixing words semantically linked to your main topic usually takes minutes once you know where to look. Below: the code example, where to edit it based on your stack, the usual causes, and the best practices that keep the issue away.
Example
TXT
Sujet : audit SEO
Mots associés : analyse, rapport, vérification, score, recommandation, technique
Where to make the change
WordPress: via the theme (header.php / Yoast / Rank Math) or a dedicated SEO plugin.
Shopify: under Online Store → Preferences or in the theme's Liquid code.
Static HTML site: directly in the page's source file.
Next.js / React: via the framework's <head> metadata (Next Metadata API, react-helmet, etc.).
Other CMS: SEO panel in the admin, or edit the template.
Common causes and resolution
