**I17 — Defined Expertise Domains** (Chapter 9 - E-E-A-T): consistent knowsAbout for each author, clear specialization

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 performance on impressions.

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

How to check (step by step)

Approach: check via crawl (list + export). Recommended tool: **Your WG Analyzer**.

  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 that violate the criterion.

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

How to fix properly

Strategy: fix the minimum necessary, then stabilize.

  • Rewrite the outline: 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 over 7–14 days (impressions/CTR/indexing).

Concrete example (illustrative)

Example (illustrative):

  • **Context**: comparison page for a law firm in Rabat
  • **Before**: generic H1 + sections without hierarchy (incoherent H2/H3).
  • **After**: intent-oriented H1 + H2 by sub-questions (case: comparison page — law firm).
  • **Note**: Goal: make the outline “scannable” and aligned with intent.

Checklist to tick

FAQ

Frequently asked questions — I17

What is the most common mistake on “Defined Expertise Domains”?

Fixing an isolated page without fixing the template/import: the mistake comes back at the next generation.

Which tool is the fastest for large-scale checking?

For this type of criterion, a crawl (e.g. Screaming Frog) + targeted verification in Your WG Analyzer 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) + add an automatic check (crawl or test) before import into production.
