PART 1 - Fundamentals Chapter 12 - UX & Accessibilité Keyword : navigation clavier

This is often seen as an error on mass-generated sites.

The **L15 — Keyboard Navigation** criterion is part of our SEO checklist (335 criteria). Here, you have a **practical** method to check and fix it — with a concrete example.

What exactly this criterion covers

This is often seen as an error on mass-generated sites.

**L15 — Keyboard Navigation** (Chapter 12 - UX & Accessibility): Site fully navigable by keyboard (Tab, Enter, Escape)

Why it matters (SEO + UX)

Why it matters: it is a lever for CTR and perception in SERP. When poorly applied, we often observe: ambiguity (wrong associated query), duplication between pages, or loss of ranking performance.

On volume-generated sites, this criterion also serves as a **safeguard**: a stable rule prevents 1,000 errors at once.

How to check (step by step)

Approach: tool-assisted test (validator / performance). Recommended tool: **Hotjar/Clarity (if available)**.

  1. Open the page in Chrome → DevTools → Performance/Network tab.
  2. Run WebPageTest and note the main weak point.
  3. Check if the problem repeats on “money” pages.

Tip: first isolate 10 “representative” URLs (top pages + generated pages) before scaling the fix.

How to fix properly

Strategy: make a “clean” fix (no patch), then measure.

  • Simplify the mobile journey (visible menu/CTA, no aggressive popups).
  • Fix instabilities (CLS) and interactivity (INP) if affected.
  • Test on 2–3 screen sizes and re-measure.

Then: re-crawl 50–200 URLs, then monitor Search Console for 7–14 days (impressions/CTR/indexing).

Concrete example (illustrative)

Example (illustrative):

  • **Context**: blog article for auto garage in Marseille
  • **Before**: Confusing menu on mobile + hidden CTA + visible CLS.
  • **After**: Simplified navigation + visible CTA + visual stability.
  • **Note**: Goal: readability + engagement (which indirectly helps SEO).

Checklist to tick

  • [ ] Mobile first
  • [ ] Respects: tab
  • [ ] CTA visible
  • [ ] No major friction
  • [ ] Visual stability OK
