Criterion D3: Natural Keyword Density — guide + checklist

PART 1 - Fundamentals Chapter 4 - Content Keyword : densité mots-clés naturelle

Here we talk about a criterion that often makes the difference in audits.

The criterion D3 — Natural Keyword Density 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

Here we talk about a criterion that often makes the difference in audits.

D3 — Natural Keyword Density (Chapter 4 - Content): 0.5-1% (3-6 occurrences/1000 words), avoid keyword stuffing (>2% = risk)

Why it matters (SEO + UX)

Why it matters: it is a safeguard against duplication and cannibalization. When poorly applied, we often observe: ambiguity (wrong associated query), duplication between pages, or performance loss on indexing rate.

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: Google Trends.

  1. Open the source code and locate the concerned element (tag/structure).
  2. Check the hierarchy and consistency with H1 + intro.
  3. Run a crawl to detect pages violating the criterion.

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

How to fix properly

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

  • Rewrite the plan: clear H1, H2 = sub-questions, H3 = details.
  • Add a differentiating element (scope, method, example) to avoid duplication.
  • Check consistency with the intent (info / comparison / action).

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

Concrete example (illustrative)

Example (illustrative):

  • Context: training page for dentist in Lille
  • Before: generic H1 + sections without hierarchy (incoherent H2/H3).
  • After: intent-oriented H1 + H2 by sub-questions (case: training page — dentist).
  • Note: Goal: make the plan scannable and aligned with intent.

FAQ

Frequently asked questions — D3

What is the most common mistake on “Natural Keyword Density”?

Fixing an isolated page without correcting the template/import: the error returns at the next generation.

Which tool is the fastest for large-scale checking?

For this type of criterion, a crawl (e.g. Screaming Frog) plus targeted verification in Google Trends is generally the fastest combo.

How to prevent this from happening again on 10K generated pages?

Freeze an auto-generation rule (title/structure/schema/URLs) plus add automatic control (crawl or test) before production import.
