PART 2 - Advanced Strategies Chapter 14 - GEO & AEO Keyword : fichier llms.txt

This criterion seems “simple”, but it creates many discrepancies in production.

The **M5 — llms.txt File** 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 criterion seems “simple”, but it creates many discrepancies in production.

Why it matters (SEO + UX)

Why it matters: it is a UX point that eventually translates into SEO. When poorly applied, we often observe: ambiguity (wrong associated query), 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 prevents 1,000 errors at once.

How to check (step by step)

Approach: validation via Search Console (real data). 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 fix.

How to fix properly

Strategy: repair, re-crawl, and monitor in Search Console.

  • Rewrite the plan: clear H1, H2 = sub-questions, H3 = details.
  • Add a differentiating element (scope, method, example) to avoid duplication.
  • Check consistency with 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 SEO training in Casablanca
  • **Before**: generic H1 + sections without hierarchy (incoherent H2/H3).
  • **After**: intent-oriented H1 + H2 by sub-questions (case: category page — SEO training).
  • **Note**: Goal: make the plan “scannable” and aligned with intent.

FAQ

Frequently asked questions — M5

What is the most common mistake on “llms.txt File”?

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

Which tool is fastest for large-scale checking?

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

How to prevent this from recurring on 10K generated pages?

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