This error is often seen on mass-generated sites.

Criterion N4 — Public API 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 error is often seen on mass-generated sites.

N4 — Public API (Chapter 15 - Agentic SEO): Programmatic interface for AI agents, clear documentation.

Why it matters (SEO + UX)

Why it matters: it is a comprehension signal for the engine. 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: 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 violating 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 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: training page for online courses in Paris
  • Before: generic H1 + sections without hierarchy (incoherent H2/H3).
  • After: intent-oriented H1 + H2 by sub-questions (case: training page — online courses).
  • Note: Goal: make the plan scannable and aligned with intent.

FAQ

Frequently asked questions — N4

What is the most common mistake on “Public API”?

Applying an overly 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) plus targeted verification in Your WG Analyzer is generally the fastest combo.

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

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