This criterion is discreet… until it blocks SEO performance.

The criterion **I15 — Lessons Learned** 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 criterion is discreet… until it blocks SEO performance.

**I15 — Lessons Learned** (Chapter 9 - E-E-A-T): Sharing challenges encountered and solutions found

Why it matters (SEO + UX)

Why it matters: it’s a UX point that eventually translates into SEO. When poorly applied, we often observe: ambiguity (wrong query associated), duplication between pages, or loss of performance on Core Web Vitals.

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: express audit (manual + 1 tool). Recommended tool: **People Also Ask**.

  1. Open the source code and locate the concerned element (tag/structure).
  2. Check the hierarchy and coherence 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: make a “clean” fix (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 coherence 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**: category 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: category page — law firm).
  • **Note**: Goal: make the plan “scannable” and aligned with intent.

FAQ

Frequently asked questions — I15

What is the most common mistake on “Lessons Learned”?

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

Which tool is the fastest for large-scale checking?

For this type of criterion, a crawl (e.g. Screaming Frog) + targeted verification in People Also Ask is generally the fastest combo.

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

Freeze a self-generation rule (title/structure/schema/URLs) + add an automatic check (crawl or test) before production import.
