PART 1 - Fundamentals Chapter 9 - E-E-A-T Keyword : page à propos détaillée

Here we are talking about a criterion that often makes the difference in an audit.

The **H9 — Original Infographics** criterion is part of our SEO checklist (335 criteria). Here, you have a **practical** method to check and correct it — with a concrete example.

What this criterion covers exactly

Here we are talking about a criterion that often makes the difference in an audit.

**H9 — Original Infographics** (Chapter 8 - Images): Unique informational visuals, linkable assets for backlinks

Why it’s important (SEO + UX)

Why it matters: it’s a safeguard against duplicate content/cannibalization. When misapplied, we often see: ambiguity (wrong query associated), duplication between pages, or performance loss on Core Web Vitals.

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

How to check (step by step)

Approach: crawl check (list + export). Recommended tool: **Squoosh**.

  1. Open the page in Chrome → DevTools → Performance/Network tab.
  2. Launch 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 correction.

How to fix it properly

Strategy: apply a rule, then check neighboring pages.

  • Convert to WebP/AVIF + compress (Squoosh/ImageOptim).
  • Add width/height to avoid CLS.
  • Write a contextual alt (useful, not stuffed with keywords).

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

Concrete example (illustrative)

Example (illustrative):

  • **Context**: FAQ page for SEO training in Tunis
  • **Before**: Images in PNG 2–4 MB, no explicit dimensions.
  • **After**: WebP/AVIF conversion + dimensions + descriptive alt (context: FAQ page).
  • **Note**: Objective: reduce weight and improve rendering (and sometimes image search).

Checklist to tick

  • [ ] Optimized weight
  • [ ] Respects: unique informational visuals
  • [ ] Modern format
  • [ ] Dimensions defined
  • [ ] Useful and contextual alt

Frequently asked questions — I1

What is the most common mistake on “Original Infographics”?

Applying an overly generic automatic pattern (same logic on all pages) without adding a differentiating element.

Which tool is the fastest for checking at scale?

For this type of criterion, a crawl (e.g., Screaming Frog) + a targeted check in Squoosh 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 importing into production.
